Need to run mysqld command in ubuntu WHM terminal to up the website [closed]

I am using ubuntu Os and WHM/Cpanel for my websites.

Few days ago my websites stoped working without any reason, I have not done anything with my.cnf file.

Even not able to access the PHPMYADMIN and not able to take backup.

After adding few lines in my.cnf file

[mysqld]                                                                                                                bind-address = 0.0.0.0                                                                                                    user=root                                                                                                               pid-file     = /var/run/mysqld/mysqld.pid                                                                                socket       = /var/run/mysqld/mysqld.sock                                                                               port         = 3306                                                                                                                                                                                                                              [client]                                                                                                                port         = 3306                                                                                                      socket       = /var/run/mysqld/mysqld.sock

Then use mysqld commond , after that PHPMYADMIN starts working.

But now, the website and PHPMYADMIN stops anytime.

I need to run mysqld commond to start the website and PHPMYADMIN.

Is their any solution so that the website and PHPMYADMIN will not stop.

Thanks in advance
