how to fix InnoDB corrupted data structure? – CentOS

I removed mysql and installed mariadb, I guess removing mysql broke InnoDB (I’m new to this).

Edit1: According to the post below, the InnoDB implementation which used to be known as the "plugin" is included with mysql, and mariadb I’m presuming. So should I just reinstall mariadb to fix innodb?

https://dev.mysql.com/doc/refman/5.5/en/innodb-installation.html

When you use the InnoDB storage engine 1.1 and above, with MySQL 5.5 and above, you do not need to do anything special to install: everything comes configured as part of the MySQL source and binary distributions.

Edit2: I used yum history undo on the install of mariadb, the removal of mysql and the install of mysql. Then installed mariadb. This didn’t fix the problem but did clean up some unused mysql dependencies.

Edit3: The following commands from the post below solved my problem:

sudo rm -rf /var/lib/mysql/*
sudo mysql_install_db -u mysql
