MySql won't start after upgrade from 5.1 to 5.7

Hello World,
as the subject says I tried to perform an upgrade from a MySql 5.1 to a 5.7 and now the service is not running. I used the remi repo to do it.

- CentOS release 6.7 (Final)
- Mysql Ver 14.14 Distrib 5.7.20, for Linux (x86_64) using EditLine wrapper

Actually if I launch the mysql service I got this:

Code: Select all

[root@www etc]# mysql -u root -p
Enter password:**********
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
System is right: there's no mysql.sock file there and even if I try to "touch" it the output is gonna be:

Code: Select all

[root@www local]# 2018-01-11T22:58:31.381719Z 0 [Note] /usr/sbin/mysqld (mysqld 5.7.20-log) starting as process 31906 ...

Diggin' around the web I tried some solutions and I found someone with similar issue trying to launch this command:

Code: Select all

sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking --user=mysql &
But I got this result and nothing is running anyway.

Code: Select all

[root@www local]# sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking --user=mysql &
