replication配置过程

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

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

3.利用主库的备份构建备库

4.在备库上启动复制（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

设置从库read_only=1

在主库插数据然后在从库上验证同步是否正常

主库上查看show processlist
