1) Check whether InnoDB is enabled on the server. To check login to shell as root and go to mysql prompt.
i) root@server [~]#mysql
ii) mysql> show engines;
Search for InnoDB and check whether it is Enabled or Disabled.
iii) mysql> quit
2) Now if it is disabled and to make it enabled on the server edit /etc/my.cnf file and comment skip-innodb line as bellow.
i) nano /etc/my.cnf
#skip-innodb
ii) Restart mysql service.
/etc/init.d/mysql restart
Thanks
