replication配置過程

1.grant replication slave,replication client on *.* to 'repli_user'@'192.168.0.5' identified by 'testpassword'

2.配置主庫（log-bin,server-id,expire_logs_days=5)

3.利用主庫的備份構建備庫

4.在備庫上啓動複製（change master to,start slave）

change master to

master_host='192.168.0.1',

master_port=3306,

master_user='repl_user',

master_password='testpassword',

master_log_file='mysql-bin.000045',

master_log_pos=107;

 

show slave status\G

start slave

設置從庫read_only=1

在主庫插數據而後在從庫上驗證同步是否正常

主庫上查看show processlist
