I'm trying to set up a XAMPP installation on my work laptop – that's why I go for XAMPP and not regular LAMP so I don't have to have start-up services etc. But I get an error when trying to start MySQL. I've tried changing permissions but I don't really know what to do.
Here is my error log:
110922 21:39:20 mysqld_safe Starting mysqld daemon with databases from /opt/lampp/var/mysql

Does anyone have any idea how to fix this?
Thank you for your time! 🙂

I've never used XAMPP's version of MySQL, so I'm not sure whether it tries to run MySQL as the logged in user, or as a special system user called mysql (like regular MySQL does).
But what you need to do is ensure that what ever user the database is running with has permissions on the folder
/opt/lampp/var/mysql/and all it's contents. You need to ensure both the ownership and the permissions are correct.The commands should be of the form (where you replace
[USER]with the right username):chown -R [USER] /opt/lampp/var/mysql/ chmod -R 755 /opt/lampp/var/mysql/
