    amazing i’ve been going at this for the last 3 days and finally got it thanks to you telling me about the compiling flag ..can you please include this information in your directions to install?

    Does the plugin really need to use fast mutex?

    It’s not included in the Debian installs of mySQL and, according to mySQL themselves, is about to be deprecated:

    ‘fast’ mutex implementation has several shortcomings and provides no measurable performance benefit. Since nowadays most platforms offer support for adaptive locks, MySQL’s ‘fast’ mutex is going to be removed in MySQL 6.0.

    I don’t really want to be having to take my server offline and go through the hassles of recompiling a custom install of mySQL [no doubt breaking other stuff in the process], just to be able to use a WP plugin.

    Hi Madra,

    You don’t need to build your own MySQL to work with ClouSE: just download an official build from and it will work with ClouSE.

    Does the plugin really need to use fast mutex?

    The plugin does not use fast mutex at all, but it must be compiled with the same flags as the MySQL binaries. The official MySQL builds that are distributed by Oracle do get compiled with the fast mutex and so does ha_clouse*.so.

    Please post further questions to this forum.

    Hi, I followed the instruction to install MySQL from, however at step 15, when I log into mysql, it shows the old version of MySQL installed earlier. How do I change it to the new version?

    Hi Albert,

    It’s possible that your MySQL server startup scripts still point to the old installation. The exact steps for deploying startup scripts varies for different Linux distros, however most should work if you copy mysql.server from support-files to /etc/init.d/ and make links to it in /etc/rcN.d/ dirs. For RedHat-based systems, you can use chkconfig --add mysql.server to automatically make links in /etc/rcN.d/ dirs; for Debian-based systems you can use update-rc.d mysql.server defaults for that purpose.
