用的是我们开发用的库，部署在测试环境，测试环境的mysql版本居然是5.1的。

1.主服务器配置

cd /etc,找到my.cnf，然后再这个配置文件加上复制要用的配置

server-id = 1
log-bin=mysql-bin
binlog-do-db=wx

2.从机配置

打开my.ini，加上和服务器类似的配置

server-id=2
log-bin=mysql-bin 
replicate-do-db=wx

4.主机上建复制账号

主机的mysql命令行下执行如下命令，建一个用来复制的账号，和密码

grant replication slave 
on *.* 
to 'replication'@'%' identified by '123'; 

mysql> show master status\G
*************************** 1. row ***************************
 File: mysql-bin.000003
 Position: 256
 Binlog_Do_DB: wx
Binlog_Ignore_DB: 
1 row in set (0.00 sec)

5.从机关联主机操作

从机上执行关联主机的命令，并重启从机。

change master to 
master_host = '192.168.146.120', 
master_user = 'replication', 
master_password = '123', 
master_log_file = 'mysql-bin.000003', 
master_log_pos = 256; 
start slave; 

主机上wx库找张表，插入一条语句，从机立刻复制过来。

查看从机状态。

mysql> show slave status\G
