最近研究mysql,从oracle官网下了一个最新的5.6的mysql,压缩版的。今天尝试一下Mysql的复制功能,花了好久才整出来,把心得分享出来。
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。
