    Hi :)

    As we have the mysqltunner script in place i want to recommend to have always also the latest version of Tunning primer script on Centminmod :)

    I know it is very old and has many years to get an update but it works and many times is useful :)

    MySQL Tuning Primer Script in Launchpad

    Thanks

    mysqltuner.pl included in Centmin Mod is from mysqlmymonlite.sh's modified mysqltuner.pl version at mysqlmymon.com so needs modifying for each version update. So will need to update it myself.

    ah was an easier update apparently to add my modifications to mysqltuner.pl 1.6.18

    updating is as easy as removing existing /root/mysqltuner.pl and downloading latest one
    Code (Text):
    rm /root/mysqltuner.pl
    wget -O /root/mysqltuner.pl https://centminmod.com/centminmodparts/mysqltuner/mysqltuner.pl
    


    example run of mysqltuner.pl 1.6.18
    Code (Text):
    /root/mysqltuner.pl   
     >>  MySQLTuner 1.6.18 - Major Hayden <major@mhtx.net>

        Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1
    Variables to adjust:
        query_cache_limit (> 512K, or use smaller result sets)

    Yes i know but i was ask for it to be there ready to go after Centminmod installation....

    But no big deal if you want to keep your modified version as default :)

    doh.. mysql tuning-primer.sh is too ancient and some suggestions are not relevant to newest mysql, percona and mariadb server versions so probably won't be included by default
