MySQL start FAILED on VM Virtual Box

Recently  I had on issue with MySQL Start-up with VM. my environment was
Host OS   : Debian / BOSS
Guest OS : CentOS
Application running in CentsOS. We tried to replicate the same in Debian/BOSS but wouldn't because some missing packages. so decided to go with Virtual Machine concept.

When we boot the CentOS from Debian/BOSS, MySQL Failed to start.

As we followed my error.log we managed to start the MySQL.

1) Network Adapter settings in your VM settings to be bridged mode

2) Change bind address  in /etc/mysql/my.cnf to 0.0.0.0
bind-address = 0.0.0.0
 start the server by /etc/init.d/mysql start

3) gone through the log file (img),
