简单的MySQL数据库主从同步配置

Master配置：


 代码如下 复制代码 
log-bin = mysql-bin
server-id = 1
binlog-do-db = powerdns #要同步的数据库
 


Master新增slave账号：


 代码如下 复制代码 
mysql> GRANT replication slave ON *.* TO 'slave'@'192.168.1.2' IDENTIFIED BY 'passwd';  
mysql> FLUSH privileges;
 


重启Master MySQL，查看Master状态信息，记住File名称，POS位置。


 代码如下 复制代码 
mysql> show master status;  
+------------------+----------+--------------+------------------+
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+-------()-----------+
| mysql-bin.000002 |      309 | powerdns     | mysql            |
+------------------+----------+--------------+------------------+
1 row in set (0.00 sec)
 


Slave配置：


 代码如下 复制代码 
server-id =2
 


开始同步：


 代码如下 复制代码 
mysql> CHANGE master TO master_host='192.168.1.1',master_user='slave',master_password='passwd',
master_log_file='mysql-bin.000002',master_log_pos=309;  
mysql> START slave;
 


查看Slave同步状态：


 代码如下 复制代码 
mysql> SHOW slave STATUSG;
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
