Cannot Start MYSQL Server Mac - mysql

I am currently trying to run mysql server on a mac, but the Start MySQL Server from the preferences pane doesn't work, and neither does starting it from the Terminal. I have found a lot of fixes, but none of them work. This is my first time using MySQL, I have very little (just a bit of Java) programming experience, and this is my first StackOverflow post in a long time (please help me learn if I did it incorrectly!).
I installed this version(didn't use brew): mysql-5.7.21-1-macos10.13-x86_64
My machine is 64 bit
What I've tried:
Uninstalled and reinstalled MySQL using this process:
To uninstall MySQL and completely remove it (including all databases) from your Mac do the following:
Open a terminal window Use mysqldump to backup your databases to text
files! Stop the database server sudo rm /usr/local/mysql sudo rm -rf
/usr/local/mysql* sudo rm -rf /Library/StartupItems/MySQLCOM sudo rm
-rf /Library/PreferencePanes/My* edit /etc/hostconfig and remove the line MYSQLCOM=-YES- rm -rf ~/Library/PreferencePanes/My* sudo rm -rf
/Library/Receipts/mysql* sudo rm -rf /Library/Receipts/MySQL* sudo rm
-rf /private/var/db/receipts/mysql https://community.jaspersoft.com/wiki/uninstall-mysql-mac-os-x
When I open the folder where mysql is installed, I do not have permissions to open the data or keychain folders. So, I decided it was a permissions problem and tried this: Cannot start Mysql on Mac. When I tried to start the server, I got the following error:
sudo /usr/local/mysql/support-files/mysql.server start Starting MySQL

Please help!
EDITED: I uninstalled and reinstalled with brew. Using these instructions: http://stefan.magnuson.co/articles/osx/reinstalling-mysql-on-osx-with-homebrew/ Now it works.

I uninstalled and reinstalled SQL with Homebrew using these instructions: http://stefan.magnuson.co/articles/osx/reinstalling-mysql-on-osx-with-homebrew/ Now it works.

This small diagnosis worked for me in MAC...
open Your Terminal and use the following command to check all the instances or mysql that are currently running in your machine.
1) ps -ef | grep mysql
If you found any process Id with the above command.
2) sudo kill -9 [PID]
Where [PID] is the process id next to username
now try restarting mysql again using the mysql server pane or go to terminal and type the following command
sudo /usr/local/mysql/support-files/mysql.server start

In XAMPP MySQL database is not starting

Although if have written some commands in terminal like this:
sudo killall mysql
sudo chmod -Rf 777 /Applications/XAMPP/xamppfiles/var/mysql/
sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start

mysql.server start wont start the mysql server

Whenever I type "mysql.server start" on OSX terminal I get this error:
Maria-MacBook-Pro:~ mariakocsis$ mysql.server start

Even if I try to run mysql by MAMP, its not working.
Before the error I followed this commands:
cd ; nano .bash_profile
/usr/local/mysql/bin/mysql -v
/usr/local/Cellar/mysql/5.7.22/bin/mysqld_safe ; exit;
source ~/.bash_profile mysql -v
in your terminal type in: mysql
source ~/.bash_profile mysql -v
SHOW GLOBAL VARIABLES LIKE 'PORT';
sudo apt-get purge mysql-server mysql-client mysql-common mysql-server-core-5.7 mysql-client-core-5.7
sudo nano /etc/my.cnf
How can I reset this things?
And how I can start mysql server?
Use command below:
To start mysql: mysqld start
To stop mysql: mysqld stop
To restart: mysqld restart

How to stop mysql on OsX from the command line

This question bas many answers, I tried what I found – did not work
So, I tried sudo mysqld stop.
Still I see the mysql processes running:
0 317 1 0 11:15AM ?? 0:00.02 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/usr/local/mysql/data --pid-file=/usr/local/mysql/data/anarinsky-mbp.smartdestinations.com.pid
74 3562 317 0 11:40AM ?? 0:00.41 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/usr/local/mysql/data/anarinsky-mbp.smartdestinations.com.err --pid-file=/usr/local/mysql/data/anarinsky-mbp.smartdestinations.com.pid
The same happens if I do “sudo kill -9 3562”.
Trying to go to /Library/LaunchDaemons does not retrieve any mysql entries
ls /Library/LaunchDaemons | grep mysql
The service command does not work:
-bash: service: command not found
My Os X version is 10.9.2
There are two answers I know, it might not help since you search a long time.
1.if you install mysql from dmg, you can close it in "system preferences".
2.And besides that, you can start/stop/restart mysql by:
sudo /usr/local/mysql/support-files/mysql.server start
sudo /usr/local/mysql/support-files/mysql.server stop
sudo /usr/local/mysql/support-files/mysql.server restart
To install Homebrew, open Terminal/iTerm and run following command or check https://brew.sh/
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Install mysql
$ brew install mysql.
Install brew services first
$ brew tap homebrew/services.
Start mysql
$ brew services start mysql.
In order to avoid mysqld from auto restarting after killed, try execute all these 3 commands:
$ brew services stop mysql
$ sudo launchctl unload /Library/LaunchDaemons/com.mysql.mysql.plist
$ sudo launchctl unload /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist

Is it possible to upgrade the MySQL in MAMP to MySQL 5.7?

Is it possible to upgrade the MAMP MySQL library to 5.7?
I am currently running 5.6 (which I upgraded to using MAMP’s upgrade script
)
Or would I need to install MySQL natively on my system? (macOS 10.11 El Capitan)
If someone could point me in the right direction… Thanks!
Upgrade MAMP to Mysql 5.7

sudo /Applications/MAMP/bin/start.sh
echo "migrate to new version"
/Applications/MAMP/Library/bin/mysql_upgrade -u root --password=root -h 127.0.0.1
UPDATE: Version 5.0 of MAMP now includes MySQL 5.7 already in the installer! Just upgrade your core MAMP setup and you are set to go with MySQL instead of having to jump through technical hoops like this.
Leaving answer below as a reference for anyone who needs it.
While I have read this answers and comments here—as well as some similar linked tutorials on GitHub and such—there were a few things that confused me in some of the tutorials. Such as instructions to set chmod -O o+rw and even a comment about creating a symbolic link to /tmp/mysql.sock; why do that when MAMP out of the box should be self contained and not require such changes? So here are the instructions I have put together based on my experience getting MySQL upgraded for MAMP 4.4.1 on mac OS 10.3.4 (High Sierra).
First, get a copy of the macOS binaries for MySQL 5.7; note that as of me posting this answer MySQL 5.7.22 is the current version so adjust this URL to whatever new version you might want to use:
curl -OL https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.22-macos10.13-x86_64.tar.gz
Decompress it like this:
tar xfvz mysql-5.7*
Copy the bin/ and share/ stuff into MAMP via Rsync like this:
sudo rsync -arv --progress mysql-5.7.*/bin/* /Applications/MAMP/Library/bin/ --exclude=mysqld_multi --exclude=mysqld_safe
sudo rsync -arv --progress mysql-5.7.*/share/* /Applications/MAMP/Library/share/
Copy your existing MySQL 5.6 database directory like this; just note that the mysql56 directory is temporarily needed during the upgrade but can be discarded after the rest of the MySQL 5.7 upgrade is done:
sudo cp -r /Applications/MAMP/db/mysql56 /Applications/MAMP/db/mysql57
Once that is done, get rid of MySQL database specific binaries like this for upgrade:
sudo rm -rf /Applications/MAMP/db/mysql57/mysql/innodb_*
sudo rm -rf /Applications/MAMP/db/mysql57/mysql/slave_*
And instead of changing permissions to o+rw just change the owner of the DB directory to your current user; this matches how MAMP installs this stuff:
sudo chown -R ${USER}:admin /Applications/MAMP/db/mysql57
Now run this Sed command to adjust the mysqld_safe script to point to the new MySQL 5.7 path; you could probably just open this file up in a text editor and change all instances of mysql56 to mysql57as well:
sed -i.bak 's/mysql56/mysql57/g' /Applications/MAMP/Library/bin/mysqld_safe
Finally, if you use MAMP and set a my.cnf file, that should be set in /Applications/MAMP/conf/my.cnf… But by doing this upgrade, the default search path of the my.cnf in MAMP will be /usr/local/mysql/etc/ instead of the expected /Applications/MAMP/conf/ since that is where the new binary expects it to be set. Clearly we’re not going to recompile MySQL at this point so the cleanest/simplest thing to do to make your MAMP setup truly portable again is to change this line in the startMysql.sh from this:
/Applications/MAMP/Library/bin/mysqld_safe --port=8889 --socket=/Applications/MAMP/tmp/mysql/mysql.sock --pid-file=/Applications/MAMP/tmp/mysql/mysql.pid --log-error=/Applications/MAMP/logs/mysql_error_log &
To this; note we are adding the --defaults-extra-file= option before all the otgers:
/Applications/MAMP/Library/bin/mysqld_safe --defaults-extra-file=/Applications/MAMP/conf/my.cnf --port=8889 --socket=/Applications/MAMP/tmp/mysql/mysql.sock --pid-file=/Applications/MAMP/tmp/mysql/mysql.pid --log-error=/Applications/MAMP/logs/mysql_error_log &
With all of that command line work done, launch MAMP via the application, start the MySQL and Apache servers and then drop back into the command like to run this command to upgrade the databases:
/Applications/MAMP/Library/bin/mysql_upgrade --user=root --password=root --port=3306 --socket=/Applications/MAMP/tmp/mysql/mysql.sock --force
And finally run this command to get the mysql.sock properly set for MAMP path instead of that /tmp/mysql.sock path:
/Applications/MAMP/Library/bin/mysql_config_editor --verbose set --socket=/Applications/MAMP/tmp/mysql/mysql.sock
When this is all done, and you have confirmed MySQL is running as expected, just toss the old MySQL 5.6 directory like this:
sudo rm -rf /Applications/MAMP/db/mysql56
With all that done you should all be set to cleanly use MySQL 5.7 under MAMP 4.4.1.
I encountered problems upgrading to MySQL 5.7.22 described in Giacomo1968’s answer.
The updated procedure worked well on El Capitan with MySQL 5.7.18.
I have written an updated bash script for this procedure:

echo "Building Mysql 5.7 Folder"

echo "Finally, if you use MAMP and set a my.cnf file, that should be set in /Applications/MAMP/conf/my.cnf… But by doing this upgrade, the default search path of the my.cnf in MAMP will be /usr/local/mysql/etc/ instead of the expected /Applications/MAMP/conf/ since that is where the new binary expects it to be set.

How to start MySQL server from command line on Mac OS Lion?

I installed mySQL on my Mac. Beside starting the SQL server with mySQL.prefPane tool installed in System Preferences, I want to know the instructions to start from command-line.
I do as follows:
After
su root
I start the mySQL server by command-line, but it produces an error as below:
sh-3.2# /usr/local/mysql/bin/mysqld
111028 16:57:43 [Warning] Setting lower_case_table_names=2 because

insensitive
111028 16:57:43 [ERROR] Fatal error: Please read "Security" section of
the manual to find out how to run mysqld as root!
111028 16:57:43 [ERROR] Aborting
111028 16:57:43 [Note] /usr/local/mysql/bin/mysqld: Shutdown complete
Simply:
mysql.server start
mysql.server stop
mysql.server restart
Try /usr/local/mysql/bin/mysqld_safe
Example:
shell> sudo /usr/local/mysql/bin/mysqld_safe
(Enter your password, if necessary)
(Press Control-Z)
shell> bg
(Press Control-D or enter "exit" to exit the shell)
You can also add these to your bash startup scripts:
export MYSQL_HOME=/usr/local/mysql
alias start_mysql='sudo $MYSQL_HOME/bin/mysqld_safe &'
alias stop_mysql='sudo $MYSQL_HOME/bin/mysqladmin shutdown'
I like the aliases too ... however, I've had issues with MySQLCOM for start ... it fails silently ... My workaround is akin to the others ... ~/.bash_aliases
alias mysqlstart='sudo /usr/local/mysql/support-files/mysql.server start'
alias mysqlstop='sudo /usr/local/mysql/support-files/mysql.server stop'
As this helpful article states:
On OS X to start/stop MySQL from the command line:
sudo /usr/local/mysql/support-files/mysql.server start
sudo /usr/local/mysql/support-files/mysql.server stop
On Linux start/stop from the command line:
/etc/init.d/mysqld start
/etc/init.d/mysqld stop
/etc/init.d/mysqld restart
Some Linux flavours offer the service command too
# service mysqld start
# service mysqld stop
# service mysqld restart
or
# service mysql start
# service mysql stop
# service mysql restart
If you installed it with homebrew, the binary will be somewhere like
/usr/local/Cellar/mysql/5.6.10/bin/mysqld
which means you can start it with
/usr/local/Cellar/mysql/5.6.10/support-files/mysql.server start
and stop it with
/usr/local/Cellar/mysql/5.6.10/support-files/mysql.server stop
Edit: As Jacob Raccuia mentioned, make sure you put the appropriate version of MySQL in the path.
Maybe your mysql-server didn't start.
You can try
/usr/local/bin/mysql.server start
sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
sudo /Library/StartupItems/MySQLCOM/MySQLCOM stop
make alias in .bash_profile
alias start_mysql="/Library/StartupItems/MySQLCOM/MySQLCOM start"
alias stop_mysql="/Library/StartupItems/MySQLCOM/MySQLCOM stop"
and if you are trying to run as root use following safe mode
sudo ./bin/mysqld_safe
if you are still having issues starting, a recommended read:
mysql5.58 unstart server in mac os 10.6.5
For me this solution worked on mac Sierra OS:
sudo /usr/local/bin/mysql.server start
Starting MySQL
SUCCESS!
My MySQL is installed via homebrew on OS X ElCaptain. What fixed it was running
brew doctor
which suggested that I run
sudo chown -R $(whoami):admin /usr/local
Then:
brew update
mysql.server start
mysql is now running
If it's installed with homebrew try just typing down mysql.server in terminal and that should be it.
AFAIK it executable will be under /usr/local/bin/mysql.server.
If not you can always run following "locate mysql.server" which will tell you where to find such file.
If you have MySQL installed through Homebrew these commands will help you:
# For starting
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
# For stoping
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
MySql server startup error 'The server quit without updating PID file '
if you have installed mysql from homebrew
close mysql server from preferences of mac
ps ax | grep mysql
#kill all the mysql process running
sudo kill -9 pid

On mac Big Sur and MySQL 5.7, I needed to stop/start with:
sudo launchctl load -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
and
sudo launchctl unload -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
This answer came from https://coolestguidesontheplanet.com/start-stop-mysql-from-the-command-line-terminal-osx-linux/
In my case, I had downloaded the mysql server and installed it but I didn't click on the run server that showed up on the last installer page.
In order to start my server manually in the terminal (without adding aliases), I used this in the terminal and it works.
Start Server:
sudo launchctl load -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
Stop Server:
sudo launchctl unload -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist

Have you set a root password for your mysql installation? This is different to your sudo root password. Try /usr/local/mysql/bin/mysql_secure_installation
