Missing /var/lib/mysql/mysql.sock file

Question

I\'m trying to access mysql and when I run the mysql command, I get the following.

[root@ip-10-229-65-166 tpdatabase-1.8.0.28356]# mysql

ERR

Answer 1

rm -rvf /var/lib/mysql/ib_logfile*
touch /var/lib/mysql/mysql.sock
touch /var/lib/mysql/mysql.pid
chown -R mysql:mysql /var/lib/mysql
systemctl restart mysql

try this and check the permission of both /var/lib/mysql/mysql.sock and /tmp
