mysql主从复制搭建

标签：eve   tcp   mysqld   start   restart   mysql   主从   send   wait   

1、准备工作：

     准备一台主服务器，我的IP地址为192.168.13.138，和一台从服务器：192.168.13.137，数据库版本一致，主从库都建好相应的库和表；

2、修改主从服务器的mysql配置：    

　　#vi /etc/my.cnf
　　[mysqld]
　　log-bin=mysql-bin //[必须]启用二进制日志
　　server-id=222 //[必须]服务器唯一ID，取服务器IP最后一段

3、重启主从库的mysql服务：

     #service mysqld restart

4、在主服务器上创建mysql账户并授权给从服务器：

　　mysql>GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO repl@‘192.168.13.%‘ IDENTIFIED BY ‘repl‘;

5、查询master的状态：

　　mysql>show master status;　　

+------------------+----------+--------------+------------------+--------------- ----+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_ Set |
+------------------+----------+--------------+------------------+--------------- ----+
| mysql-bin.000001 | 329 | | | |
+------------------+----------+--------------+------------------+--------------- ----+

6、开放主服务器的mysql端口：

　 #firewall-cmd --add-port=3306/tcp

7、配置从服务器：

　　mysql>change master to master_host=‘192.168.13.138‘,master_user=‘repl‘,master_password=‘repl‘,
         　　master_log_file=‘mysql-bin.000001‘,master_log_pos=329;

　　mysql>start slave;

8、检查从服务器复制功能的状态：

　　mysql> show slave status \G
