Answer 1

Your mysql server might be started, it seems the socket leading to it isn’t available at the path you’re providing to it (/var/run/mysqld/mysqld.sock).

You must change this socket path to the appropriate one in your machine.
The best way to find it is the following in a console : sudo find / -name mysqld.sock
Then you’ll get the path and you’ll just have to change it in your configuration file.
