Question

I’d like to move all my mysql databases to another parition. I’ve tried the brazillion guides out there but I’ve not found anything that works!

Whenever I change the ‘datadir’ in my.cnf MySQL ceases to function!

$ mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Here’s some more info:

$ mysqld -u root
101110 16:37:03 [Warning] Ignoring user change to 'root' because the user was set to 'mysql' earlier on the command line
101110 16:37:03 [Warning] Can't create test file /home/krainboltgreene/repo/databases/mysql/krainboltgreene-desktop-gateway.lower-test
101110 16:37:03 [Warning] Can't create test file /home/krainboltgreene/repo/databases/mysql/krainboltgreene-desktop-gateway.lower-test

And here’s the conf file:

As @cdhowie says, it looks like you may just need to chown your new directory to mysql. This is usually accomplished through sudo chown -R mysql:mysql directoryname

Let us know if that works.
