问题:

I installed mySQL for my Mac. Beside starting the SQL server with mySQL.prefPane tool installed in System Preference, I want to know the instruction to start from command-line. I do as follow:

After

su root

I start the mySQL server by command-line, it produce error as below:

sh-3.2# /usr/local/mysql/bin/mysqld

111028 16:57:43 [Warning] Setting lower_case_table_names=2 because file system for /usr/local/mysql-5.5.17-osx10.6-x86_64/data/ is case 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

Please help me!

EDIT:

The reason is here: http://dev.mysql.com/doc/refman/5.5/en/changing-mysql-user.html

A solution is described in the xdazz's answer below.

回答1:

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'


回答2:

Simply:

mysql.server start

mysql.server stop

mysql.server restart



回答3:

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' 


回答4:

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 


回答5:

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.



回答6:

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



回答7:

maybe your mysql-server didn't started

you can try

/usr/local/bin/mysql.server start



回答8:

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.



回答9:

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


回答10:

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



回答11:

For me this solution worked on mac Sierra OS:

sudo /usr/local/bin/mysql.server start
Starting MySQL
SUCCESS!

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
