start MySQL server from command line on Mac OS Lion

Question

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-li

Answer 1

maybe your mysql-server didn't started

you can try

/usr/local/bin/mysql.server start

Answer 2

111028 16:57:43 [ERROR] Fatal error: Please read "Security" section of the manual to find out how to run mysqld as root!

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

Answer 3

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'

Answer 4

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' 

Answer 5

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
