MySQL快速搭建主从关系

转至元数据起始

对新实例部署一键快速实现主从关系，根据官方提供的工具mysql-utilities包中mysqlreplicate。
在使用工具需要注意:添加用户时,从库IP地址要明确指定,不要使用带有'%'格式
命令使用格式:mysqlreplicate --master=root@localhost:3306 --slave=root@localhost:3310 --rpl-user=rpl:passwd
–master 指定主库的连接信息
–slave 指定从库的连接信息
–rpl-user 指定用于复制的用户信息，这个用户需要提前在 master 上创建好

 

mysqlreplicate --master=xx:[email protected]:3318 --slave=xx:[email protected]:3318 --rpl-user=xx:oo -p

[root@test9 ~]#  mysqlreplicate --master=xx:[email protected]:3318 --slave=xx:[email protected]:3318 --rpl-user=xx:oo -b
