How to convert InnoDB to MyISAM

Although at times faster, you will find InnoDB a very large headache when it comes to table corruption and may want to convert to MyISAM. First backup your databases. Do note that some databases like WordPress may require innoDB. Be sure to backup your databases before hand. Once you have performed this, the following commands may be useful in converting InnoDB to MyISAM:


mysql -e "SELECT concat('ALTER TABLE ', TABLE_NAME,' ENGINE=MYISAM;') FROM Information_schema.TABLES WHERE TABLE_SCHEMA = 'db_name' AND ENGINE = 'InnoDB' AND TABLE_TYPE = 'BASE TABLE'"

/etc/init.d/mysql stop
mkdir -p /root/innodb.bak
mv /var/lib/mysql/ib* /root/innodb.bak/
/etc/init.d/mysql start


To restore use the following:

 


cp /root/innodb.bak/* /var/lib/mysql
echo innodb_force_recovery=4 >> /etc/my.cnf
service mysql restart
