I am trying to install the InnoDb plugin for mysql 5.1.61, I have successfully done this in the past on a slightly older version of mysql (less than 5.1.38) however I am currently trying to do this on 5.1.61.
Apparently the Innodb plugin is no longer available for download and instead is bundled in with the download of the server from MySQL.
After installing the RPMs available on the Mysql 5.1 download page I have attempted to enable the innodb plugin as described on the mysql site by adding the line ignore_builtin_innodb into the configuration file but all this does is disable innodb completely.
I have noticed that there is no file called ha_innodb.so anywhere on the server after instillation so it appears that the plugin is not bundled with this version of mysql now as is claimed, or at least its not bundled in the download direct from mysql.
Does anyone know if there is something I am missing, or if the innodb plugin is available for download independently of the mysql distribution that I can install manually?
Turns out this is a known problem as the InnoDB Plugin is not built for RedHat 3, 4, SuSE 9 or for Generic Linux for 5.1 and must be built manually which I am not prepared to do. I have instead decided to bite the bullet and upgrade to MySQL 5.5 where the InnoDB Plugin in now the built in InnoDB driver.
