Difference between JOIN and INNER JOIN
They are functionally equivalent, but INNER JOIN can be a bit clearer to read, especially if the query has other join types (i.e. LEFT or RIGHT or CROSS) included in it.

Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2)
Are you connecting to “localhost” or “127.0.0.1” ? I noticed that when you connect to “localhost” the socket connector is used, but when you connect to “127.0.0.1” the TCP/IP connector is used. You could try using “127.0.0.1” if the socket connector is not enabled/working.
