One of our server had Mysql failing to start on reboot with below error

tail -n 100 /var/log/mysqld.log
2022-03-08 3:53:37 0 [Note] Crash recovery finished.
2022-03-08 3:53:37 0 [Note] Server socket created on IP: ‘127.0.0.1’.
2022-03-08 3:53:37 0 [ERROR] mysqld: Can’t create/write to file ‘/var/run/mysqld/mysqld.pid’ (Errcode: 2 “No such file or directory”)
2022-03-08 3:53:37 0 [ERROR] Can’t start server: can’t create PID file: No such file or directory

Solution to this was

Create a new folder mkdir -p /var/run/mysqld/

Chown mysql.mysql /var/run/mysqld/

[root@ok1146s1 run]# mkdir /var/run/mysqld
[root@ok1146s1 run]# chown mysql:mysql /var/run/mysqld/
[root@ok1146s1 run]# /scripts/restartsrv_mysql
