mysql的主主(M-M)复制配置
mysqlde
主主复制架构
一、环境描述
服务器
master1: 192.168.0.124
服务器
master2: 192.168.0.129
二、主主配置过程
1
、创建同步用户：
服务器
master1
：
grant replication slave,file on *.* to 'master'@'192.168.0.129' identified by '123456';
flush privileges;
服务器
master2
：
grant replication slave,file on *.* to 'master'@'192.168.0.124' identified by '123456';
flush privileges;
2
、修改
mysql
配置文件
master1
：
vim /etc/my.cnf
log-bin=mysql-bin
server-id = 10
replicate-do-db=mysql
replicate-ignore-db=test
auto_increment_increment=2
auto_increment_offset=1
service mysqld restart
master2
：
log-bin=mysql-bin
server-id = 20
replicate-do-db= mysql
replicate-ignore-db=test
auto_increment_increment=2
auto_increment_offset=2
service mysqld restart
3
、重启
mysql
服务后，进入
mysql
命令行
master1:
mysql> flush tables with read lock;
mysql> show master status;
记录二进制文件位置和
pos
------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000005 | 106 | | |
+------------------+----------+--------------+------------------+
mysql> unlock tables;
mysql> change master to
> master_host='192.168.0.129',master_user='master',master_password='123456',master_log_file='mysql-bin.000004', > master_log_pos=106;
mysql> start slave;
master2:
mysql> flush tables with read lock;
mysql> show master status;
------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000004 | 106 | | |
+------------------+----------+--------------+------------------+
mysql> unlock tables;
mysql> change master to
> master_host='192.168.0.124',master_user='master',master_password='123456',
> master_log_file='mysql-bin.000005', master_log_pos=106;
mysql> start slave;
4
、查看
master1
和
master2
的服务器的状态：
mysql> show slave status\G;
查看：
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
都显示yes为状态正常，直接进行数据测试即可
