    [mysqld]
    #
    # Remove leading # and set to the amount of RAM for the most important data
    # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
    # innodb_buffer_pool_size = 128M
    #
    # Remove leading # to turn on a very important data integrity option: logging
    # changes to the binary log between backups.
    # log_bin
    #
    # Remove leading # to set options mainly useful for reporting servers.
    # The server defaults are faster for transactions and fast SELECTs.
    # Adjust sizes as needed, experiment to find the optimal values.
    # join_buffer_size = 128M
    # sort_buffer_size = 2M
    # read_rnd_buffer_size = 2M
    datadir=/var/lib/mysql
    socket=/var/lib/mysql/mysql.sock

    # Disabling symbolic-links is recommended to prevent assorted security risks
    symbolic-links=0

    log-error=/var/log/mysqld.log
    pid-file=/var/run/mysqld/mysqld.pid
