MySQL 5.7 upgrade process failed

I am getting error MySQL 5.7 upgrade. Please let me know this fix.

(XID kb2ypk) The system failed to connect to the "MySQL" database "mysql" because of an error: CR_CONNECTION_ERROR (Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)) at /usr/local/cpanel/Whostmgr/Mysql/Upgrade.pm line 234.

Obtained version information from system.
Proceeding with MySQL/MariaDB upgrade despite the following:
Normal: The selected MySQL version (5.7) is the same as the currently installed MySQL version (5.7). No upgrade will be performed at this time, though the normal upgrade steps will still be executed. This is only useful if a previous upgrade failed while partially completed.
Critical: MySQL enables "strict mode" by default as of version 5.7. Strict mode controls how MySQL handles invalid or missing values in data-change statements such as INSERT or UPDATE. Applications not built with strict mode enabled may cause undesired behavior; please verify applications using MySQL are compatible before upgrading. More information about strict mode is availablehere.
