mysql双机互备方式如何配置-创新互联

这篇文章主要介绍了mysql双机互备方式如何配置，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

A库：192.168.190.130

B库：192.168.190.131

A库建用户

grant FILE,SELECT, replication slave on *.* to 'gaok_bak'@'192.168.190.131' identified by 'gaok';

flush privileges;

show grants for 'gaok_bak'@'192.168.190.131';

B库建用户

grant FILE,SELECT, replication slave on *.* to 'gaok_bak'@'192.168.190.130' identified by 'gaok';

flush privileges;

show grants for 'gaok_bak'@'192.168.190.130';

A库my.cnf配置(添加以下内容)：

[mysqld]

server-id = 1

log_bin = /usr/local/mysql/data/mysql-bin.log

relay_log = /usr/local/mysql/data/mysql-relay.log

log-slave-updates = ON

sync_binlog=1

auto-increment-increment=10

auto-increment-offset=1

B库my.cnf配置(添加以下内容)：

[mysqld]

server-id = 2

log_bin = /usr/local/mysql/data/mysql-bin.log

relay_log = /usr/local/mysql/data/mysql-relay.log

log-slave-updates = ON

auto-increment-increment=10

auto-increment-offset=1

sync_binlog=1

#####两个mysql重启

A库、B库查看master状态

A库:

change master to

master_host='192.168.190.131',

master_user='gaok_bak',

master_password='gaok',

master_log_file='mysql-bin.000002',

master_log_pos=154;

start slave;

show slave status\G

B库：

change master to

master_host='192.168.190.130',

master_user='gaok_bak',

master_password='gaok',

master_log_file='mysql-bin.000002',

master_log_pos=154;

start slave;

show slave status\G

----------测试是否正确。
