从

mysql> mysql -uroot -p'Fghj7S0Cl#ef'
mysql> create database ywgl;
mysql> show global variables like '%relay%';
mysql> stop slave;
mysql> change master to master_host='172.16.4.41',master_user='repl',master_password='d60v#-MXf>qn',master_port=3306,master_log_file='mysql-bin.000004',master_log_pos=1255618;

mysql> set global read_only=1;
mysql> flush privileges;
mysql> start slave;
mysql> show slave status\G

# 主从报错的话，比如是Got fatal error 1236 可以在主上执行刷新日志操作
mysql> flush logs;
