installing mysql

I am hoping to run a set of scripts that will identify and index olfactory receptors using BLAST and mysql. That means I need to sort out how mysql is installed on noctilio, which should be great fun.

First thing I noticed when I downloaded mysql, is that we have 3 other version of mysql on the server! :)

I knew this was going to cause some problems so I needed to uninstall all versions of MySQL in order to get this working properly. I basically followed this awesome post. Here it is reiterated for Mac OsX Yosemite:

Remove MySQL completely per The Tech Lab

• ps -ax | grep mysql

• stop and kill any MySQL processes
• brew remove mysql
• brew cleanup
• sudo rm /usr/local/mysql
• sudo rm -rf /usr/local/var/mysql
• sudo rm -rf /usr/local/mysql*
• sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
• sudo rm -rf /Library/StartupItems/MySQLCOM
• sudo rm -rf /Library/PreferencePanes/My*
• launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
• 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*
• restart your computer just to ensure any MySQL processes are killed
• try to run mysql, it shouldn't work

Brew install MySQL per user Sedorner from this StackOverflow answer

• brew doctor and fix any errors
• brew update
• brew install mysql
• unset TMPDIR
• mysqld -initialize --verbose --user=whoami --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp #note the above command has been edited to replace the deprecated form
• mysql.server start
• run the commands Brew suggests, add MySQL to launchctl so it automatically launches at startup

Okay now to have MySQL start at launch, follow this lovely post. Homebrew can basically set this up for you.

brew tap homebrew/services

Apparently it is no longer supported, so also run these commands:
brew untap homebrew/boneyard brew tap gapple/services

When you run this command, mysql should start:
brew services start mysql
