Centos Mysql主從備份

一、主庫mysql

設置my.cnfsql

server_id = 2 必須惟一數據庫

binlog-do-db = abo-assist 備份的數據庫ide

log-bin=mysql-bin 開啓binlog日誌

 

建立同步帳號並受權server

grant replication slave on *.* to 'replication'@'%' identified by '123456';同步

 

二、從庫io

server_id = 10 必須惟一ast

 

三、開啓主從同步(從庫上操做)file

mysql> stop slave;

mysql>change master to master_host='192.168.190.131',master_user='replication',master_password='123456',master_port=3336,master_log_file='mysql-bin.000002',master_log_pos=120;

mysql> start slave;

 

備註

清除從庫日誌

mysql>show slave status\G (查看從庫備份狀態)

mysql>reset master

mysql訪問外部地址

myql -h -u -p
