i save this configuration for my.cnf :

[mysql]

# CLIENT #
port = 3306
socket = /var/lib/mysql/mysql.sock

[mysqld]

# GENERAL #

but after restart mysql

server.pid deleted and ERROR! The server quit without updating PID file (/var/lib/mysql/server.pid).

what can i do?

i disable SELinux and reboot but not solve

default settings:

mysql> show variables like ‘innodb_log_file_size’;
±---------------------±--------+
| Variable_name | Value |
±---------------------±--------+
| innodb_log_file_size | 5242880 |

1 row in set (0.00 sec)

mysql> show variables like ‘datadir’;
±--------------±----------------+

mysql> show variables like ‘innodb_data%’;

Did you checked mysql error log ? It will provide more details what causing it. Can you please show relevant error log entries for that from /var/lib/mysql/server-error.log file.
