MySQL - Installing InnoDB Plugin I have a Master/Slave Replication Setup, both servers run MySQL 5.1.61.

I want to upgrade the master server to a stronger machine with the following:


2 processors - 6 cores each
48GB of RAM


To utilize both processors I need to install the InnoDB Plugin

I have a few questions:


Is it possible to install the InnoDB plugin just on the master and not on the slave?
Are there any other implications to installing the plugin?
What parameters do I need to change in my.cnf to better utilize the plugin and the multi core options?
Any recommended tutorial for installing the plugin?
Goto to the following folder

cd /usr/lib64/mysql/plugin
ls -l

You have located the InnoDB Plugin files

Getting back to your question :


  1.Is it possible to install the InnoDB plugin just on the master and not on the slave?


Yes


  2.Are there any other implications to installing the plugin?


Once the plugin is installed and you configure my.cnf for the Master, do not use the options for InnoDB Plugin on another server where the plugin was not installed.


  3.What parameters do I need to change in my.cnf to better utilize the plugin and the multi core options ?


Please see my past posts on this

  4.Any recommended tutorial for installing the plugin?


Please follow the instructions from the MySQL Documentation on InnoDB Plugin Installation
