Linux下指定mysql数据库数据配置主主同步的实例

grant replication slave on . to 'bravedu'@'192.168.1.%' identified by 'brave123';
flush privileges;

[mysqld] 
server-id = 1 
log-bin=//mysql/binlog/binlog (路径要根据自己的安装设置)
binlog-do-db = dbname (要同步的数据库名)
binlog-ignore-db=mysql

log-slave-updates
sync_binlog=1
auto_increment_offset=1
auto_increment_increment=2
replicate-do-db = dbname
replicate-ignore-db = mysql,information_schema

mysql>flush tables with read lock; 
mysql>show master status\G
1. row
File: mysql-bin.000001    (这里注意 设置从服务器的时候要用)
Position: 106             (这里注意设置从服务器的时候要用)
Binlog_Do_DB: dbname
Binlog_Ignore_DB: mysql
1 row in set (0.00 sec)

mysql>unlock tables;
