Not able to get mysql running on my mac - mysql

I'm trying to install mysql on my mac but unable to start server. When I try to start mysql server, I get this error in the logs: Can't start server: can't create PID file: Permission denied. Can't create/write to file ~/Downloads/mysql-5.5.32-osx10.6-x86_64/data/HOSTNAME.pid. I have symlinked /usr/local/mysql to ~/Downloads/mysql-5.5.32-osx10.6-x86_64. And all files/directories under /usr/local/mysql and ~/Downloads/mysql-5.5.32-osx10.6-x86_64 are owned by mysql. I'm trying start mysql server as root. Searched everywhere for this, but no luck. I tried with mysql 5.5 and 5.6. Same problem with both the versions. Any clues?

I'd highly recommend you install mysql using Homebrew. To do this:
ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"
brew install mysql
The output of the second command may give you a few extra steps. Follow them and you should be set.

You have to start it as an administrator. Write sudo and a space followed by the command you will use to start MySQL.

Use below permission to grant permissions:
check your mysqld location, mine is this:
do this:
ls -ld /usr/local/var/mysql
sudo chmod a+w /usr/local/var/mysql

ERROR 2002 (HY000) while using brewed mysql

I was using MAMP and have removed it completely from my MAC OS.
Post this,
I installed mysql5.7 using brew
Added mysql path to zshrc / bash profile
Started mysql service using brew services start mysql#5.7
Now when I try to access mysql on command line it gives me error ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/Applications/MAMP/tmp/mysql/mysql.sock' (2)
Where as I have already added socket path to /tmp/mysql.sock in my.cnf as well as tried creating symlink of same to ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/Applications/MAMP/tmp/mysql/mysql.sock' (2)
but no luck.
Advice on same will be highly appreciated!
this is a sign that the server did not really start.
Run:
ps aux|grep mysql
If you find a mysql server process , there are chances is not correctly installed.
the best is to uninstall, if you don't have anything important in the database and reinstall it again . You could try reinstall , but this is usually not fixing the issue.
brew services list
brew uninstall mysql#YOUR_VERSION
brew install mysql#DESIRED_VERSION
[1] I faced a similar issue a few weeks ago, the fix was changing my brew permissions. Try some of the answers in this stackoverflow answer and the rest of the thread:
sudo chown -R $(whoami) $(brew --prefix)/*
[2] Brew tells you a bunch of folders having permission issues and the fix for each of them. Run commands mentioned in brew doctor and it should work. Here is what my brew doctor had to say:
You should change the ownership of these directories to your user.

ERROR! The server quit without updating PID file on El captian

I have problem mysql starting, i was update to El captian on mac.
In terminal,
brew install mysql
mysql.server start
but it not working
this is error message.
Starting MySQL... ERROR! The server quit without updating PID file(/usr/local/var/mysql/Heo-MacBook-Pro.local.pid).
help me please!
I had the same problem using brew command to start mysql service.
If you are using MacOS, go to System Preferences and click on MySQL icon. Probably you'll see information message about permission denied in some directories. All you need to do is to give permission to that.
That's worked for me.
Open your terminal
Execute this command: sudo chown -R mysql /usr/local/mysql/data
Try this first:
/usr/local/var/mysql/support-files/mysql.server restart
If that doesn’t fix
Remove or backup the /etc/my.cnf
also try this method:
sudo /usr/local/var/mysql/support-files/mysql.server start
Starting MySQL
. ERROR! ....................
remove the .err files like so:
rm *.err /usr/local/var/mysql/data/
Solution working for my case:
Check your error log at /usr/local/var/mysql/Heo-MacBook-Pro.local.err
If there is something like this in the log: ...[Note] Unable to delete pid file: Permission denied..., which means mysql does not have the permission to your mysql folder
Use the following command in terminal to grant the permission: sudo chown -R mysql /usr/local/var/mysql/
The Problem could also be a version mismatch. My db was installed with Homebrew as version 5, later unintentionally upgraded to version 8.
Check the most recent error log at /usr/local/var/mysql/<your-computers-name.some.domain>.err
You can conveniently read the last couple of lines (e.g. 40) of the file with tail -n 40 <your-computers-name.some.domain>.err
You may find a hint about upgrading istructions in this case.

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' [duplicate]

This question already has answers here:
Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (38)
(43 answers)
Closed 21 days ago.
I installed MySQL on Mac OS X Mountain Lion with homebrew install mysql, but when I tried mysql -u root I got the following error:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
What does this error mean? How can I fix it?
You'll need to start MySQL before you can use the mysql command on your terminal. To do this, run brew services start mysql. By default, brew installs the MySQL database without a root password. To secure it run: mysql_secure_installation.
To connect run: mysql -uroot. root is the username name here.
This happened after the homebrew install and occurs due to permission issues. The following commands fixed the issue.
sudo chown -R _mysql:mysql /usr/local/var/mysql
sudo mysql.server start
It's probably because MySQL is installed but not yet running. [...] To verify that it's running, open up Activity Monitor and under "All Processes", search and verify you see the process "mysqld".
You can start it by installing "MySQL.prefPane".
The above quote is from the blog Obscured Clarity, "Install MySQL on Mac OS X", where you can also find the complete tutorial that I found most helpful.
Run: brew info mysql
And follow the instructions. From the description in the formula:
Set up databases to run AS YOUR USER ACCOUNT with:
unset TMPDIR
mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
To set up base tables in another folder, or use a different user to run
mysqld, view the help for mysql_install_db:
mysql_install_db --help
and view the MySQL documentation:
* http://dev.mysql.com/doc/refman/5.5/en/mysql-install-db.html
* http://dev.mysql.com/doc/refman/5.5/en/default-privileges.html
As others have pointed out this is because MySQL is installed but the service isn't running. There are many ways to start the MySQL service and what worked for me is the below.
To start the service:
Go to "System Preference"
At the bottom pane there should be MySql icon.
Double click that to launch the 'MySQL Server Status' and press the button 'Start MySQL Server'
My env:
Mac Yosemite 10.10.3
Installed Package: /Volumes/mysql-advanced-5.6.24-osx10.8-x86_64
Solutions revolve around:
changing MySQL's permissions
sudo chown -R _mysql:mysql /usr/local/var/mysql
Starting a MySQL process
sudo mysql.server start
Just to add on a lot of great and useful answers that have been provided here and from many different posts, try specifying the host if the above commands did not resolve this issue for you, i.e
mysql -u root -p h127.0.0.1
The designated data directory /usr/local/var/mysql/ is unusable. You can remove all files that the server added to it.
MacOS:
$brew services stop mysql
$brew services list
$brew uninstall mysql
$brew install mysql
$brew postinstall mysql
If Any error found then run those cmd
! Warning: this will delete any databases on this server:
$sudo rm -rf /usr/local/var/mysql
$sudo rm /usr/local/etc/my.cnf
$brew postinstall mysql
$brew services start mysql
$mysql_secure_installation
Completed All process of secure installation then run
$mysql -u root -p
Congratulations you’ve just set up mysql!
Warning - this method will remove all of your databases in the /usr/local/var/mysql folder
I had MySQL installed with Homebrew, and the only thing that fixed this for me was re-installing MySQL.
On my company laptop, I didn't have permission to uninstall MySQL from my computer via Homebrew:
$ brew uninstall mysql --ignore-dependencies
Uninstalling /usr/local/Cellar/mysql/8.0.12... (255 files, 233.0MB)
Error: Permission denied # dir_s_rmdir - /usr/local/Cellar/mysql/8.0.12
So instead, I removed and reinstalled MySQL manually:
$ sudo rm -rf /usr/local/Cellar/mysql
$ brew cleanup
$ sudo rm -rf /usr/local/var/mysql
$ brew install mysql
And that worked!
Looks like your mysql server is not started. I usually run the stop command and then start it again:
mysqld stop
mysql.server start
Same error, and this works for me.
Below I'm including the latest instructions from brew install mysql so newer searches for this issue can benefit:
$ brew install mysql
==> Downloading https://homebrew.bintray.com/bottles/mysql-5.6.26.yosemite.bottle.1.tar.gz
######################################################################## 100.0%
==> Pouring mysql-5.6.26.yosemite.bottle.1.tar.gz
To connect:
mysql -uroot
To have launchd start mysql at login:
ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents
Then to load mysql now:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
Or, if you don't want/need launchctl, you can just run:
mysql.server start
In my case I loaded mysql now via launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist and was then able to launch $ mysql and be on my way.
This problem related to /usr/local/var/mysql folder access, I remove this folder and reinstall mysql.
uninstall mysql with brew :
brew uninstall mysql
sudo rm -r /usr/local/var/mysql
brew install mysql#8.0
mysql -u root
This solution works fine for me!
BUT YOU LOST ALL YOUR DATABASES! WARNING!
This fixed my issue when I restarted the mysql service. Just run:
brew services start mysql
In my case it was simply a matter of deleting a lock file.
sudo rm -f /tmp/mysql.sock.lock
Ough, that took me a while to figure out. I saw it in a comment. After installing mysql using brew, and starting the service (perhaps using sudo brew services start mysql) then run:
$ mysqld
And MySQL should be running for your thereafter.
For me it was simple as running:
/usr/local/opt/mysql/bin/mysqld_safe
instead of mysqld
I went through this issue and I managed to run mysql server using below solution
Install mysql through .dmg(https://dev.mysql.com/downloads/mysql/5.7.html), you will get mysql service panel in system preferences then start mysql from the panel and try
mysql -u root -p
Images attached for reference
just hit "brew services start mysql" in terminal
I found the solution to my problem. It was indeed because my MySQL server was not running.
It was caused by MySQL not being correctly set up on my machine, thus not being able to run.
To remedy this, I used a script which installs MySQL on Mac OSX Mountain Lion, which must have installed missing files.
Here is the link: http://code.macminivault.com/
Important Note: This script sets the root password as a randomly generated string, which it saves on the Desktop, so take care not to delete this file and to note the password. It also installs MySQL manager in your system preferences. I'm also not sure if removes any existing databases, so be careful about that.
After working on this for several hours what worked for me was
go to /etc/mysql/ and edit the my.cnf file. Add the following
[client]
port = 3306
socket = /var/run/mysqld/mysqld.sock
AFTER USING ALL THE ABOVE SOLUTIONS, NOTHING WORKED FOR ME BUT THIS WORKED.
I you have installed MySQL using HomeBrew then check System Preferences > MySQL in your mac that MySQL Server is stopped if it is running stop it by clicking on Stop MySQL Server and start MySQL from terminal writing the command mysqlserver.start.
If it doesn't work you can also try:-
If you have also installed MySQL workbench then just uninstall MySQL workbench and MySQL and after that install MySQL first and then MySQL workbench.
I would recommend you to run
mysql.server start
before going to
mysql -u root -p
so as to make sure that the mysql server is running before trying to login into it
This happens many times what you start/restart a machine where by no mysql server is running.
I keep coming back to this post, I've encountered this error several times. It might have to do with importing all my databases after doing a fresh install.
I'm using homebrew. The only thing that used to fix it for me:
sudo mkdir /var/mysql
sudo ln -s /tmp/mysql.sock /var/mysql/mysql.sock
This morning, the issue returned after my machine decided to shut down overnight. The only thing that fixed it now was to upgrade mysql.
brew upgrade mysql
After trying many solutions, seems like the one that finally did the trick was to connect by IP. No longer file sockets getting deleted randomly.
Just update your MySQL client config (e.g. /usr/local/etc/my.cnf) with:
[client]
port = 3306
host=127.0.0.1
protocol=tcp
Probably you might have faced some issues during the homebrew mysql installation and mysql services might not be running. If that is the case, then it might be worth trying below steps to reinstall mysql properly and then try to connect.
sudo chown -R $(whoami) /usr/local/var
sudo chown -R $(whoami) /Library/Caches/Homebrew
brew uninstall mysql
brew install mysql
mysql.server start
mysql -uroot
Homebrew will absolutely never repair the permissions using a standard reinstall, and chasing down which folder/file is corrupted will take longer than it is worth.
In this case - blow away the mysql install manually and reinstall via homebrew. Takes about 2 minutes.
cd /usr/local/var
sudo rm -rf mysql
brew install mysql
Homebrew installs mysql insecure by default, so if you want a password:
mysql_secure_installation
Then fire it up.
mysql -uroot
After installing MySQL on my mac m1 macOS Monterey, using brew install mysql I got this info:
[System] [MY-013169] [Server] /opt/homebrew/Cellar/mysql/8.0.27_1/bin/mysqld (mysqld 8.0.27) initializing of server in progress as process 3624

and this warning:
Warning: The post-install step did not complete successfully You can
try again using: brew postinstall mysql
After that I try to start MySQL using brew services start mysql, and I got this error:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket
'/tmp/mysql.sock' (2)
I managed to fix it using:
> rm -rf ~/opt/homebrew/var/mysql/
> brew postinstall mysql
Now you can connect with mysql -uroot or mysql -uroot -p.
only this has made the trick for me
brew services start --all
(after trying all answers)
I managed to solve this issue by changing localhost to 127.0.0.1
For my case, just specify host as 127.0.0.1, instead of localhost:
$ bin/mysql -uroot -p -h127.0.0.1
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.

if you are using Kali linux you might want to specify the host explicitly
do that with
mysql -h 127.0.0.1 -u root
where 127.0.0.1 is your localhost

mysql_install_db gives FATAL ERROR: Could not find my-default.cnf

I've download MySQL and I'm trying to setup the MySQL grant tables, but when I type:
scripts/mysql_install_db --basedir=/usr/local
I get the error above.
I'm not sure how to fix it, as my-default.cnf is in the support_files directory and I believe I'm setting the basedir correctly.
(This is on mac btw)
(I'm assuming you're using Homebrew, since I hit the same issue trying to do the same thing on Homebrew on my macbook)
I believe you need to point it to the actual mysql directory in the cellar as its basedir, not at /usr/local (since that's just things symlinked from the cellar dir).
So, in my case, I had to use:
$ mysql_install_db --basedir=/usr/local/Cellar/mysql/5.6.10
Need copy /usr/share/my.cnf
Try this:
sudo cp /etc/mysql/my.cnf /usr/share/mysql/my-default.cnf
sudo mysql_install_db
Its help for me on Ubuntu 14.04 and mysql 5.6.33
To extend to rascalking's answer, the current mysql installs to /usr/local/mysql/ via brew.
But to get over timestamp issue and the permission issue the full command will be:
sudo mysql_install_db --basedir=/usr/local/mysql --explicit_defaults_for_timestamp
Don't forget to set your password first incase you skipped the instruction:
/usr/local/mysql/bin/mysqladmin -u root password 'new-password'

After MySQL install via Brew, I get the error - The server quit without updating PID file

Ok, I've searched all over and have spent quite a bit of my time installing, uninstalling, trying various option but without success.
I'm on Mac OS X Lion (10.7.3) and am trying to setup a Python, MySQL.
I successfully installed Python and MySQL via HomeBrew.
Python works great.
After MySQL Installation, I followed the first 2 steps - unset and the mysql_install_db commands.
Now, when I try to start mysql "mysql.server start", I get the following error
ERROR! The server quit without updating PID file (/usr/local/var/mysql/Brajeshwar.local.pid).
Brajeshwar is my username on my machine.
I found that it was a permissions issue with the mysql folder.
chmod -R 777 /usr/local/var/mysql/
solved it for me.
EDIT 2012/09/18:
As pointed out by Kane, make sure the mysql database is properly set up before doing anything else. See “PID error on mysql.server start?” for more info.
Original answer kept for history's sake:
It most likely is a permissions issue. Check /usr/local/var/mysql/*.err. Mine said:
120314 16:30:14 InnoDB: Operating system error number 13 in a file operation.
InnoDB: The error means mysqld does not have the access rights to
InnoDB: the directory.
InnoDB: File name ./ibdata1
InnoDB: File operation call: 'open'.
InnoDB: Cannot continue operation.
120314 16:30:14 mysqld_safe mysqld from pid file /usr/local/var/mysql/janmoesen.local.pid ended
I also had to do this:
sudo chown _mysql /usr/local/var/mysql/*
I ended up with completely reinstalling of mysql, and it finally worked out.
WARNING This will remove all of your databases, so make sure to save dumps first.
brew remove mysql
brew cleanup
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
sudo rm -rf /usr/local/var/mysql
brew install mysql
mysqld --initialize --explicit_defaults_for_timestamp
mysql.server start # no sudo!
I had this issue on mac 10.10.5 Yosemite
What I did to solve this
cd /usr/local/var/mysql
sudo rm *.err && sudo rm *.pid
sudo reboot
sudo mysql.server start
I had the same issue on OS X El Capitan, here's the terminal command sequence that fixed it for me.
Delete error files (you'll have to change the path depending on your setup)
sudo rm /usr/local/mysql/data/*.err
Find the info for the mysql process that's still running and kill it:
ps -A | grep -m1 mysql | awk '{print $1}' | sudo xargs kill -9
Now restart MySQL:
/usr/local/mysql/support-files/mysql.server start
November, 2014: If you're getting this error on MySQL 5.6.x on Mac OS X Mavericks or Yosemite and want to use MySQL with PHP locally (/tmp/mysql.sock is where PHP PDO expects to find the sock file), here is what fixed it for me:
1) Uncomment the default homebrew config file lines and edit as below
$ sudo vi /usr/local/Cellar/mysql/5.6.21/my.cnf
...
basedir = /usr/local/Cellar/mysql/5.6.21
datadir = /usr/local/var/mysql
port = 3306
server_id = <UNIQUE_NUMBER_HERE_OR_LEAVE_COMMENTED_OUT>
socket = /tmp/mysql.sock
pid-file = /usr/local/var/mysql/[BOXNAME].local.pid
....
BOXNAME is what you have in your System Prefs -> Network as the unique id for your computer on the network.
2) Set permissions on all the files in the mysql datadir. These were all owned by [my_username]. MySQL is very picky about this and refuses to create the pid file unless it (the user _mysql) owns the directory.
$ sudo chown -R _mysql:mysql /usr/local/var/mysql
3) Start MySQL using the bash helper/wrapper script:
$ sudo mysql.server start
Starting MySQL
. SUCCESS!
Hope that helps. If the above doesn't work for you, try to run the mysqld_safe binary manually in the Cellar/mysql/VERSION_/bin/ directory and check what the settings are (if it runs)
sudo /usr/local/Cellar/mysql/5.6.12/bin/mysqld_safe &
If that runs, you can
ps aux | grep mysql
and see something like
[username] 6881 0.0 2.7 3081392 454836 ?? S 8:52AM 0:00.54 /usr/local/Cellar/mysql/5.6.21/bin/mysqld --basedir=/usr/local/Cellar/mysql/5.6.21 --datadir=/usr/local/var/mysql --plugin-dir=/usr/local/Cellar/mysql/5.6.21/lib/plugin --verbose --log-error=/usr/local/var/mysql/BOXNAME.local.err --pid-file=/usr/local/var/mysql/BOXNAME.local.pid
I'm not sure why that worked for me but it shows you where I got the my.cnf config file options from. You can also use the command line options to try to troubleshoot when starting mysqld manually.
If you do run manage to run MySQL server using mysqld_safe, you may have to do this to shut it down before trying the mysql.server bash helper. Resist the urge to kill -9 [PID] because you can corrupt your data.
mysqladmin -uroot shutdown
Good luck!
This worked for me:
sudo chmod -R 777 /usr/local/var/mysql/
sudo /usr/local/mysql/support-files/mysql.server start
This worked for me on 10.12.2 :
$ rm /usr/local/var/mysql/*.err
then
$ brew services restart mysql
If I remember correctly it is a permissions issue. Try to 'touch' and 'chmod' the pid file or the folder the file is held in.
My issue was that I started server as sudo once and then tried to restart as a local user.
Here mysql was not able to write to '.err' file owned by root.
I had to remove that file and restart the server:
sudo rm /usr/local/var/mysql/*.err
mysql.server start
Try this (OSX)
Step 1:
ps -aux | grep mysql
Then kill the 4 digits PID number
Step 2: kill 1965
Step 3: mysql.server start
Or having hard time to locate those PID numbers, try this below
Step 1 again: ps -aux | grep mysql
Step 2 again: killall
Step 3 again: mysql.server start
I’ve got a similar problem with MySQL on a Mac (Mac Os X Could not startup MySQL Server. Reason: 255 and also “ERROR! The server quit without updating PID file”). After a long trial and error process, finally in order to restore the file permissions, I’ve just do that:
launch the Disk Utilities.app
choose my drive on the left panel
click on the “Repair disk permissions” button
This did the trick for me. Hoping this can help someone else.
Find usr/local/var/mysql/your_computer_name.local.err file and understand the more information about error
Location : /usr/local/var/mysql/your_computer_name.local.err
It's probably problem with permissions
Find if mysql is running and kill it
ps -ef | grep mysql
kill -9 PID
where PID is second column value
2. check ownership of mysql
ls -laF /usr/local/var/mysql/
if it is owned by root, change it mysql or your user name

sudo chown -R mysql /usr/local/var/mysql/
For me it worked with:
unset TMPDIR
mysql_install_db --user=`whoami` --basedir="$(brew --prefix mariadb)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
What worked for me was:
Go to your mysql installation directory
sudo chmod -R 777 data
Then go back one directory
cd support-files/
sudo ./mysql.server start
After that the server started running.
But the problem with this method is that I have to repeat this every time I want to start the mysql now. Don't know why it started behaving like this suddenly.
I had this problem on Linux, but the cause is relevant to any mysql installation. In my case, the server was crashing before startup was complete and the pid file updated. The error messages were seen when starting up mysqld directly instead of via "service mysql start".
In my case, the cause was the partition where the log files were located being full. Removing log files permitted mysql to start again. To test for this issue, go to the location of your mysql activity logs, and do df ..
If you have upgraded your mysql installation to 8.x, check if your previous version is supported for upgradation.
If not, mysql will not work! Uninstall your mysql along with all configuration files in /usr/local/var/mysql (remove the whole folder). Reinstall mysql.
NOTE: reinstalling might lead to loss of data.
Please check the log , you will get more detailed information .
Use the below command to tail the error log
tail -100 /usr/local/var/mysql/<user_name>.local.err
For me , one of the directory is missing , once created the server has started .
The key takeaway is to check the .err file, by default on Mac OSX it's in /usr/local/var/mysql.
That log filed revealed to me that I had to delete the following files:
ibdata1
ib_logfile0
ib_logfile1
Running MySQL with mysql.start worked successfully after that. Note that deleting those files will likely causes data loss.
sudo chmod -R 777 /usr/local/var/mysql/
works for me.
I had the same issue:
But the situation was, every time i try to enter:
/usr/local/mysql/support-files/mysql.server start
a file named localhost.pid is created instead of iMax0.local.pid which was stated in the error:
ERROR! The server quit without updating PID file (/usr/local/mysql/data/iMax0.local.pid).
Solution that works for me was copying localhost.pid and renaming it to iMax0.local.pid.
My solution on OSX El Capitan was:
sudo chmod ugo+w /tmp
It was broken suddenly.
The error was:
ERROR! The server quit without updating PID file
and the log showed:
Can't start server : Bind on unix socket: Permission denied
It might also be helpful to note, that under OSX there is no my.cnf file by default and not needed by default, which I did not know. Good luck!
$ sudo mysql.server restart
It works for me.
I had the similar issue. But the following commands saved me.
cd /usr/local/Cellar
sudo chown _mysql mysql
This is file permission problem.
Check disk permissions and repair.
Osx => Cmd+Space => Disk Utilty => Verify Disk Permissions.
Verify completed after Repair Disk Permissions.
mysql.server start command is worked succesfuly.
None of the answers worked for me. However, I simply did sudo mysql.server start and it worked nicely.
Also, for me, it did NOT show permissions issue in *.err file.
all solutions above doesn't work for me.
but they give me some clues to fix this error.
mysql.server start ----error The server quit without updating PID file
I installed mysql#5.7 on my macbook mojave with homebrew
brew install mysql#5.7
mysql error log located in /usr/local/var/mysql/IU.lan.err,there is one line in it:
Can't open and lock privilege tables: Table 'mysql.user' doesn't exist
after trying many posts in goole search engine,I turned to baidu
https://blog.csdn.net/xhool/article/details/52398042
inspired by this post,I found the solution:
rm /usr/local/var/mysql/*
mysqld --initialize
a random password for root user will be shown in bash.
but the command mysql -uroot -p[theRandomPassword] cant work.so I have to reset password.
create a init file with contents like this
SET PASSWORD FOR 'root'#'localhost' = PASSWORD('MyNewPass');
place it in any directory easy to find,such as Desktop
mysqld --init-file=[YourInitFile] &
many logs printed on your screen.
mysql -uroot -pMyNewPass
enjoy your high-version mysql!
Happened to me because I was actually switching from MariaDB to Mysql.
Switching back to MariaDB solved this.
I'm guessing the existing database wasn't compatible.
Solved this using sudo chown -R _mysql:_mysql /usr/local/var/mysql
Thanks to Matteo Alessani
This error may be actually being show because mysql is already started. Try to see the current status by:
