I am trying to install MySQL 5.6 in amazon linux machine. by using following link.
after completing following steps.
sudo yum localinstall http://repo.mysql.com/mysql-community-release-el6-3.noarch.rpm
sudo yum install mysql-community-server
when i am starting mysql services by this command.
sudo service mysqld start
I am getting MySQL Daemon failed to start error.
Remove old mySql
sudo yum remove mysql mysql-server mysql-common mysql-client
remove all pre-installed packages. You can get a list:
rpm -qa | grep -i mysql
Then uninstall all of them. For example:
rpm -e mysql libmysqlclient15-5.0.94-0.2.4.1 <and so on>
Completely remove the /var/lib/mysql folder
cd /var/lib
rm -rf mysql
Installing fresh mySql 5.6 =>
wget http://dev.mysql.com/get/Downloads/MySQL-5.6/MySQL-5.6.23-1.el7.x86_64.rpm-bundle.tar
tar -xvf MySQL-5.6.23-1.el7.x86_64.rpm-bundle.tar
sudo yum -y install MySQL-client-5.6.23-1.el7.x86_64.rpm
sudo yum install MySQL-shared-compat-5.6.23-1.el7.x86_64.rpm
sudo yum install MySQL-server-5.6.23-1.el7.x86_64.rpm
Starting from 2015 Sep, Mysql 5.6 server is now natively available through Amazon yum repos. More info # https://aws.amazon.com/blogs/aws/now-available-amazon-linux-ami-2015-09/
You can now simply install Mysql 5.6 server using
sudo yum install mysql56-server
Then you can simply start/stop/status look using the regular service commands
service mysqld start ( restart | stop | status | )
I couldn't figure out the default root password in Amazon AMI then I simply reset the root user password by starting the mysqld service with skip grant tables
mysqld_safe --skip-grant-tables start
mysql -u root
update user set password=PASSWORD('[New Password]') where User='root';
OR
/usr/libexec/mysql56/mysqladmin -u root password 'new password'
Also, you need to run the following command to upgrade the MySQL database to 5.6
sudo mysql_upgrade -u root -p
I met the same problem on my micro instance. Check your mysql logs
If the issue is because of
InnoDB: Cannot allocate memory for the buffer pool
Adding a swap page might solve the problem. It solved for me.
You can follow this setup
http://www.prowebdev.us/2012/05/amazon-ec2-linux-micro-swap-space.html
I copied the contents if the page does not loads
Amazon EC2 Micro Instance Swap Space - Linux
I have a Amazon EC2 Linux Micro instance. Since Micro instances have only 613MB of memory, MySQL crashed every now and then. After a long search about MySQL, Micro Instance and Memory Managment I found out there is no default SWAP space for Micro instance. So if you want to avoid the crash you may need to setup a swap space for your micro instance. Actually performance wise is better to enable swap.
Steps below show how to make a swap space for your Micro instance. I assume you have AWS Account with a Micro instance running.
Run dd if=/dev/zero of=/swapfile bs=1M count=1024
Run mkswap /swapfile
Run swapon /swapfile
Add this line /swapfile swap swap defaults 0 0 to /etc/fstab
Step 4 is needed if you would like to automatically enable swap file after each reboot.
Some useful command related to SWAP space:
$ swapon -s
$ free -k
$ swapoff -a
$ swapon -a

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

[ERROR] [MY-013236] [Server] The designated data directory /opt/homebrew/var/mysql/ is unusable. You can remove all files that the server added to it.

[System] [MY-010910] [Server] /opt/homebrew/Cellar/mysql/8.0.27_1/bin/mysqld: Shutdown complete (mysqld 8.0.27) Homebrew.
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
To find out the start command for mysqld (using a mac) I can do:
ps aux|grep mysql
I get the following output, which allows me to start mysql server.
/usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=...
How would I find the necessary command to stop mysql from the command line?
Try:
/usr/local/mysql/bin/mysqladmin -u root -p shutdown
Or:
sudo mysqld stop
Or:
sudo /usr/local/mysql/bin/mysqld stop
Or:
sudo mysql.server stop
If you install the Launchctl in OSX you can try:
MacPorts
sudo launchctl unload -w /Library/LaunchDaemons/org.macports.mysql.plist
sudo launchctl load -w /Library/LaunchDaemons/org.macports.mysql.plist
Note: this is persistent after reboot.
Homebrew
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
Binary installer
sudo /Library/StartupItems/MySQLCOM/MySQLCOM stop
sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
sudo /Library/StartupItems/MySQLCOM/MySQLCOM restart
I found that in: https://stackoverflow.com/a/102094/58768
There is an alternative way of just killing the daemon process by calling
kill -TERM PID
where PID is the value stored in the file mysqld.pid or the mysqld process id which can be obtained by issuing the command ps -a | grep mysqld.
I did it with next command:
sudo killall mysqld
I found the answer here.
Use
sudo stop mysql
For Windows, you can run this command directly if mysql/bin is in your path.
mysqladmin -u root -p shutdown
Worked for me on mac
a) Stop the process
sudo launchctl list | grep -i mysql
If the result shows anything like: "xxx.xxx.mysqlxxx"
sudo launchctl remove xxx.xxx.mysqlxxx
Example:
sudo launchctl remove org.macports.mysql56-server
b) Disable to autostart the process
sudo launchctl unload -wF /Library/LaunchDaemons/xxx.xxx.mysqlxxx.plist
Example:
sudo launchctl unload -wF /Library/LaunchDaemons/org.macports.mysql56-server.plist
Finally reboot your mac
Note: In some cases if you tried "a)" first, you need to reboot again before try b).
When mysql was installed with Homebrew, it automatically restarts when killed. You need to use the following command:
brew services stop mysql
PS: If you installed a specific version, it will be mysql#X.X
On OSX 10.8 and on, the control for MySQL is available from the System Configs. Open System Preferences, click on Mysql (usually on the very bottom) and start/stop the service from that pane. https://dev.mysql.com/doc/refman/5.6/en/osx-installation-launchd.html
The plist file is now under /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
for Binary installer use this:
to stop:
sudo /Library/StartupItems/MySQLCOM/MySQLCOM stop
to start:
sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
to restart:
sudo /Library/StartupItems/MySQLCOM/MySQLCOM restart
Try killing mysqld four times in a row. It's the only thing that worked for me...
root#ubuntu:/etc/init# killall -KILL mysqld
root#ubuntu:/etc/init# killall -KILL mysqld
root#ubuntu:/etc/init# killall -KILL mysqld
root#ubuntu:/etc/init# killall -KILL mysqld
mysqld: no process found
Just keep killing it over and over until you see "mysqld: no process found".
Kill is definitly the wrong way! The PID will stay, Replicationsjobs will be killed etc. etc.
STOP MySQL Server
/sbin/service mysql stop
START MySQL Server
/sbin/service mysql start
RESTART MySQL Server
/sbin/service mysql restart
Perhaps sudo will be needed if you have not enough rights
What worked for me on CentOS 6.4 was running service mysqld stop as the root user.
I found my answer on nixCraft.
/etc/init.d/mysql stop
service mysql stop
killall -KILL mysql mysqld_safe mysqld
When you see the following information, you success
mysql: no process found
mysqld_safe: no process found
mysqld: no process found
I use this to solve the installation problem of MySQL 5.6 in Ubuntu 15.10 using this link.
During this installation, I encounter the problem saying:
"mysqld_safe A mysqld process already exists"
Just completely stop the mysqld, mysqld_safe, mysql solves the problem.
If my mysql keeps restarting
sudo rm -rf /usr/local/var/mysql/dev.work.err
mysql.server stop
worked for me.
To stop autostart of mysql on boot, the following worked for me with mysql 8.0.12 installed using Homebrew in macOS Mojave 10.14.1:
rm -rf ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
To stop MariaDB and MySQL server instance:
sudo mysqladmin shutdown
To start MariaDB and MySQL server instance:
mysqld &
To change data ownership for MariaDB and MySQL server instance:
sudo chown -R 755 /usr/local/mariadb/data
Just go to task manager.
Then in process, search mysqld.
right click on mysqld then click on stop.
with this process you can stop it without using commands.
first try this
sudo service apache2 stop
if not, then
sudo mysql stop
if not, then
sudo stop mysql
if not, then
sudo mysqladmin shutdown
I have been there, and I do with many tips, at the end of using tips that I follow will lead me to solved. So if you not solve in this issue, you just do other tips, till your issue get solved. Hopefully it's will help you. Thanks
For mysql 5.7 downloaded from binary file onto MacOS:
sudo launchctl load -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
sudo launchctl unload -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
Following worked for me on my macbook pro:
brew services stop mysql
Incase if you want to stop all brew services:
brew services stop --all
if all else fails, this help me. Every time I tried to kill the process with the last installation it will respawn.
sudo rm -rf /usr/local/var/mysql
brew reinstall mysql
For MAMP
Stop servers (but you may notice MySQL stays on)
Remove or rename /Applications/MAMP/tmp/mysql/ which holds the mysql.pid and mysql.sock.lock files
When you go back to Mamp, you'll see MySQL is now off. You can "Start Servers" again.
How can i make mysql start every time the system boot ? I need that in a dedicated server(ubuntu distro) in which i have my blog, but every time the server goes down, on booting mysql is stopped.
Btw i can use only command line.
update-rc.d allows setting init script links on Ubuntu and Debian Linux systems to control what services are run by init when entering various runlevels. It should be able to add mysql to the list of services to run at boot:
sudo update-rc.d mysql defaults
If you later want to disable running mysql on bootup:
sudo update-rc.d mysql remove
You can do it by using sysv-rc-conf, on debian based you can install it with sudo apt-get install sysv-rc-conf
then you can choose what start at boot with a simple X on the name of the deamon, all via command line
Run the following command to see your mysql current status:
/sbin/chkconfig mysqld --list
it will return a line such as below:
mysqld 0:off 1:off 2:off 3:off 4:off 5:off 6:off
to make mysql start every time the system boots, type the following:
sudo /sbin/chkconfig mysqld on
Result now from '--list' is:
mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off
No answer helped. Finally chkconfig and update-rc.d did not work with MySQL on my machine.
Solution, I had a file /etc/init/mysql.override which contained
manual
i just deleted that file
$ sudo rm /etc/init/mysql.override
Deleting
/etc/init/mysql.override
did the job in my case (HostEurope VPS with Ubuntu 12.04)
I had the same problem, so I checked how I disabled it in the first place:
https://askubuntu.com/questions/138487/how-to-keep-apache-and-mysql-from-starting-automatically
Check your /etc/init/mysql.conf to make sure you don't have start on commented out (like I did).
# MySQL Service
description "MySQL Server"
author "Mario Limonciello <superm1#ubuntu.com>"
start on runlevel [2345]
stop on starting rc RUNLEVEL=[016]
...
Rebooted the machine and it works.
$ sudo service mysql status
mysql start/running, process 972
Use the chkconfig command as per the manpage http://manpages.ubuntu.com/manpages/maverick/man8/chkconfig.8.html
Another place to look for clues as to what is and isn't starting at boot time...
/etc/init.d/.depend.start (and its buddy at shutdown time, .depend.stop)
Here's a little more info http://www.pyenet.co.nz/2-202-1-customising-system-startup-and-boot-processes/
I had 2 servers - after booting, 1 would have mysql running, the other not so much.
On the box where mysql was starting at boot time:
chkconfig wasn't even installed
there were zero links from any scripts in /etc/rc?.d/* back to /etc/init.d/mysql
BUT... /etc/init.d/.depend.start contained:
TARGETS = halt apache2 umountfs umountnfs.sh sendsigs networking umountroot reboot killprocs unattended-upgrades urandom mysql mdadm dns-clean landscape-client pppd-dns sysstat rsync sudo postfix single grub-common ondemand rc.local

rc.local: apache2 unattended-upgrades postfix mysql mdadm dns-clean landscape-client pppd-dns sysstat rsync sudo
When I simply copied this file over to the problem server, and rebooted, mysql was up & running.
With Debian 9, I installed MySQL today and typed "reboot" and mysqld restarted automatically. Also rebooted from my VPS dashboard, mysqld restarted automatically. In short, if you have Debian 9, there's nothing extra to do, it just works.
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

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 $(whoami):admin /usr/local
Then:
brew update
mysql.server start
mysql is now running
If it's installed with homebrew try just typing down mysql.server in terminal and that should be it.
AFAIK it executable will be under /usr/local/bin/mysql.server.
If not you can always run following "locate mysql.server" which will tell you where to find such file.
If you have MySQL installed through Homebrew these commands will help you:
# For starting
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
# For stoping
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
MySql server startup error 'The server quit without updating PID file '
if you have installed mysql from homebrew
close mysql server from preferences of mac
ps ax | grep mysql
#kill all the mysql process running
sudo kill -9 pid
which mysql
/usr/local/bin/mysql
Admins-MacBook-Pro:bin username$ sudo mysql.server start

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
