How to install InnoDB (step by step)

Do you own the server OR you have a Shared/Reseller plan somewhere? If you own the complete server, ssh to the server using Putty

user: root
pass: root password i.e. the one you use to access WHM

Once you are logged in, check if Innodb is already there. Execute the command:

this will tell you if Innodb is present on the server and whether it is ON or OFF. Forward the output of the above command so people here can assist you further.

 

If you see have_innodb is set to OFF. It indicate thet innodb is disabled on your server.

To enable it, ssh to your server as root and open file /etc/my.cnf with your favorite editor.

Search for line skip-innodb and comment the line by placing # in the starting of the line.

Save and quit the file and restart mysql service for changes to take effect.

HTML:

/etc/init.d/mysql restart

Now check status of InnoDb engine

HTML:

mysqladmin variables | grep have_innodb

Above command should show output as YES now.

 

What if there is no skip-innodb in the config file?

 

In this case It seems InnoDb is already enable on server.

SSH server as root, go to mysql prompt and check available database engines.

Check what do you see corresponding to InnoDB in the Support column.

 

Hi,

I have same problem,
the ibdata1 had a big volume, and I made a backup from my Databases, and removed ibdata1 file in /var/lib/mysql/ and then restored databases.
now all is good, but just I do not have the innodb engine working.

Missing innodb in "mysql> show engines;"
and also innodb is not skipped in my.cnf
root@avts1 [~]# cat /etc/my.cnf | grep "skip-innodb"
root@avts1 [~]#

looks that I need to reinstall the mysql server or mysql engine innodb on this server.

I`ll be thanksful if you update me.
regards

 

Yes, in your case you have to reinstall mysql on server or try upgrading mysql this will fix your innodb engine issue. For better performance of site I will suggest you to go with MariaDB instead of mysql.
