简单的MySQL数据库主从同步配置
Master配置：| 代码如下 | |
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 | |
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 | |
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 | |
server-id =2 | |
开始同步：
| 代码如下 | |
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 | |
mysql> SHOW slave STATUSG; Slave_IO_Running: Yes Slave_SQL_Running: Yes | |
