源码编译安装Percona Server 5.5
Percona Server（http://www.percona.com/）是MySQL的衍生版，其对MySQL进行了改进，在功能、性能和稳定性上有着显著的提高。下面介绍一下如何用源码自行编译安装目前最新版本的Percona Server 5.5。
服务器系统版本为Centos 6。
从地址http://www.percona.com/redir/downloads/Percona-Server-5.5/Percona-Server-5.5.15-21.0/source/Percona-Server-5.5.15-rel21.0.tar.gz 下载最新源码包，并拷贝到/home/software/percona下。在控制台执行以下命令：
# cd /home/software/percona
# tar zxvf Percona-Server-5.5.15-rel21.0.tar.gz
# cd Percona-Server-5.5.15-rel21.0
# CC=gcc CFLAGS="-DBIG_JOINS=1 -DHAVE_DLOPEN=1 -O3" CXX=g++ CXXFLAGS="-DBIG_JOINS=1 -DHAVE_DLOPEN=1 -felide-constructors -fno-rtti -O3"

修改/etc/my.cnf，如如下内容：
# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M - 64M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with
# other programs (such as a web server)
#
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /usr/local/mysql/data) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

注意：在标红处，可以设置字符集为utf8，缓冲区大小根据实际情况来调整。
在/usr/local/mysql目录下，创建目录：logs、tmp，并且赋予读写权限。
添加到启动项：
# cd /usr/local/mysql
# cp support-files/mysql.server /etc/rc.d/init.d/mysqld
# chmod 700 /etc/init.d/mysqld
# chkconfig --add mysqld
# chkconfig --level 345 mysqld on
安装handlersocket
# cd cd /home/software/percona/Percona-Server-5.5.15-rel21.0/storage/HandlerSocket-Plugin-for-MySQL/
# ./autogen.sh
# ./configure --with-mysql-source=/home/software/percona/Percona-Server-5.5.15-rel21.0 --with-mysql-bindir=/usr/local/mysql/bin/ --with-mysql-plugindir=/usr/local/mysql/lib/mysql/plugin
# make
# make install
初始化话数据库我就不写了，网上资料很多。完成后登录到mysql可以安装handlersocket插件了：
# mysql> INSTALL PLUGIN handlersocket SONAME 'handlersocket.so';
# mysql> SHOW PLUGINS;
