重新启动后符号链接消失

Question

I'm running Mac OS X 10.8.4

I make the following symbolic link

ln -s /Users/AlyssaPHacker/mysql/mysql.sock /tmp/mysql.sock

But every time I restart the computer, the symbolic link disappears and I have to create it again. Does anyone know how to get around this?

Answer 1

The /tmp directory is emptied when the system boots so your link is lost.

You can use the special cron @reboot entry to run your command during each boot:

@reboot ln -s /Users/AlyssaPHacker/mysql/mysql.sock /tmp/mysql.sock

in the crontab file - see the man page
