Enabling Innodb engine for MySQL

Enabling Innodb engine for MySQL

To enable Innodb engine for MySQL put following lines in `/etc/my.cnf' file

innodb_data_home_dir = /usr/local/mysql/var/
innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend
innodb_log_group_home_dir = /usr/local/mysql/var/
innodb_log_arch_dir = /usr/local/mysql/var/

The last line innodb_log_arch_dir may not be acceptable in all versions. If MySQL fails to start then check /var/log/mysql.log file to see if this configuration line is causing problems

You would also need to do:

mkdir /usr/local/mysql/var
chown -R mysql:mysql /usr/local/mysql/var

You can check with command `mysql -e 'show engines'' which engines are working.
