How to run a sudo command on mac? .. problem with mysql server I 've installed mysql server with brew, and i need to run manually this command each time my computer start to make it work with an application that I can't edit.

sudo mkdir -p -- /var/run/mysqld/ ; sudo ln -s /tmp/mysql.sock /var/run/mysqld/mysqld.sock


What I can do to call this automatically? I tried with Automator, but I don't want to enter my password each time, what is the right way to run this or to fix this? (may changing permissions and running this as normal user)

Mysql is running with my normal user, not root.
On OS X Yosemite you should add the script in:

/Library/LaunchDaemons


using this name for the script:

com.mysql.mysql.plist


and this content:

&lt;!--?xml version="1.0" encoding="UTF-8"?--&gt;
&lt;plist version="1.0"&gt;
  &lt;dict&gt;
    &lt;key&gt;KeepAlive&lt;/key&gt;
    &lt;dict&gt;
       &lt;key&gt;SuccessfulExit&lt;/key&gt;
       &lt;false/&gt;
    &lt;/dict&gt;
    &lt;key&gt;Label&lt;/key&gt;
    &lt;string&gt;com.mysql.mysqld&lt;/string&gt;
    &lt;key&gt;ProgramArguments&lt;/key&gt;
    &lt;array&gt;
      &lt;string&gt;/usr/local/mysql/bin/mysqld_safe&lt;/string&gt;
      &lt;string&gt;--user=mysql&lt;/string&gt;
    &lt;/array&gt;
  &lt;/dict&gt;
&lt;/plist&gt;


you will get MySQL started automatically every time you reboot the Mac.

be sure to set proper privileges to the script:

sudo chown root:wheel /Library/LaunchDaemons/com.mysql.mysql.plist
sudo chmod 644 /Library/LaunchDaemons/com.mysql.mysql.plist
sudo launchctl load -w /Library/LaunchDaemons/com.mysql.mysql.plist


Just tested on OS X 10.10.2 while moving out of MAMP PRO and it works like a breeze :-)
