After the change of the Maria DB databases no longer connects with PhpMyAdmin

[FabioB]

It's a new installation, I've only installed CentOS and LAMP and redirected the databases folder, there's no data. I would have liked to solve the problem rather than circumvent it.

The correct solution is to either expand the filesystem that contains /var/lib/mysql or to create a new filesystem that you can dedicate to it. Moving it under /home is a horrible hack and no solution.

[FabioB]

Ok, I will format and give different sizes to disk. The /home mount point is obligatory?

[TrevorH]

You will need a /home directory but it doesn't need to be 147GB if you only aim to keep 166MB on it.

[FabioB]

I left CenOS partitioning automatically.
Well, but, the last thing, in what mount poin is /var?

[FabioB]

All right, now it's so
