1）、在两台服务器上各自建立一个具有复制权限的用户；
|
||
2）、修改配置文件：
|
||
# 主服务器A上
|
||
[mysqld]
|
||
server-id = 10
|
||
log-bin = mysql-bin
|
||
relay-log = relay-mysql
|
||
auto-increment-offset = 2
|
||
auto-increment-increment = 1
|
||
|
||
|
||
# 主服务器B上
|
||
[mysqld]
|
||
server-id = 20
|
||
log-bin = mysql-bin
|
||
relay-log = relay-mysql
|
||
auto-increment-increment = 2 # 起始值
|
||
auto-increment-offset = 2 # 步长
|
||
|
||
|
||
3）、如果此时两台服务器均为新建立，且无其它写入操作，各服务器只需记录当前自己二进制日志文件及事件位置，以之作为另外的服务器复制起始位置即可
|
||
|
||
serverA|mysql> SHOW MASTER STATUS\G
|
||
************************** 1. row ***************************
|
||
File: mysql-bin.000001
|
||
Position: 710
|
||
Binlog_Do_DB:
|
||
Binlog_Ignore_DB:
|
||
1 row in set (0.00 sec)
|
||
|
||
server2|mysql> SHOW MASTER STATUS\G
|
||
mysql> SHOW MASTER STATUS\G
|
||
*************************** 1. row ***************************
|
||
File: mysql-bin.000003
|
||
Position: 811
|
||
Binlog_Do_DB:
|
||
Binlog_Ignore_DB:
|
||
1 row in set (0.00 sec)
|
||
|
||
4、各服务器接下来指定对另一台服务器为自己的主服务器即可：
|
||
serverA|mysql> CHANGE MASTER TO ...,MASTER_LOG_FILE='mysql-bin.000003', MASTER_LOG_POS=811
|
||
|
||
serverB|mysql> CHANGE MASTER TO ...,MASTER_LOG_FILE='mysql-bin.000001', MASTER_LOG_POS=710
|
||
|
||
|
