步骤如下：

一、编译安装两个mysql，步骤如下

安装第一个数据库(主数据库)

(红色部分为默认数据库文件路径，可改成其他如：data、var等)

tar zxvf mysql-6.0.11-alpha.tar.gz

cd mysql-6.0.11-alpha

./configure --prefix=/usr/local/mysql3306 --sysconfdir=/usr/local/mysql/etc --with-tcp-port=3306 --localstatedir=/usr/local/mysql3306/var--with-unix-socket-path=/tmp/mysql3306.sock --with-charset=utf8 --with-collation=utf8_general_ci --with-extra-charsets=gbk,gb2312,binary --enable-thread-safe-client --with-plugins=innobase --with-mysqld-user=mysql --with-charset=utf8  --with-client-ldflags=-all-static --with-mysqld-ldflags=-all-static

make && make install

安装第二个数据库(从数据库)

tar zxvf mysql-6.0.11-alpha.tar.gz

cd mysql-6.0.11-alpha

./configure --prefix=/usr/local/mysql3307 --sysconfdir=/usr/local/mysql3307/etc --with-tcp-port=3307 --localstatedir=/usr/local/mysql3307/var--with-unix-socket-path=/tmp/mysql3307.sock --with-charset=utf8 --with-collation=utf8_general_ci --with-extra-charsets=gbk,gb2312,binary --enable-thread-safe-client --with-plugins=innobase --with-mysqld-user=mysql --with-charset=utf8  --with-client-ldflags=-all-static --with-mysqld-ldflags=-all-static

make && make install

如需支持所有字符集 修改为：--with-extra-charsets=all 即可

二、分别初始化数据库脚本(在编译目录执行下)

scripts/mysql_install_db --basedir=/usr/local/mysql3306/ --user=mysql

scripts/mysql_install_db --basedir=/usr/local/mysql3307/ --user=mysql

注：可用--datadir=PATH参数指定数据库文件路径，默认为编译时-- localstatedir

三、修改从库配置文件

拷贝配置文件：

cp /usr/local/software/mysql-6.0.11-alpha/support-files/my-medium.cnf /usr/local/mysql/etc/my.cnf

cp /usr/local/software/mysql-6.0.11-alpha/support-files/my-medium.cnf /usr/local/mysql3307/etc/my.cnf

四、修改各个数据库的my.cnf文件

主要内容如下：

添加InnoDB支持：

[client]

#password       = your_password

port            = 3307                      --数据库端口号

socket          = /tmp/mysqls.sock    --sock文件路径

default-character-set=utf8            --客户端UTF8连接

[mysqld]

port            = 3307                      --数据库端口号

socket          = /tmp/mysqls.sock    --sock文件路径

default-storage-engine=INNODB

default-character-set=UTF8           --默认字符集

init_connect='SET NAMES utf8'       --以UTF8连接

skip-name-resolve                        --取消DNS反向解析

lower_case_table_names=1            --不区分表名大小写

启动数据库(进入各自目录)

主：./scripts/mysqld_safe &

从：./scripts/mysqld_safe &

配置开启自动：

cp /usr/local/software/mysql-6.0.11-alpha/support-files/mysql.server /etc/init.d/mysql

cp /usr/local/software/mysql-6.0.11-alpha/support-files/mysql.server /etc/init.d/mysql3307

修改/etc/init.d/mysql3007中basedir与datadir为即可

basedir=/usr/local/mysql3307

datadir=/usr/local/mysql3307/var

停止数据库

主：./mysqladmin shutdown

从：./mysqladmin shutdown
