mysql master slave搭建

1、

2、配置master

修改/etc/my.cnf增加

[mysqld]
log-bin = master-bin
log-bin-index = master-bin.index
server-id = 1

3、master创建一个复制用户

CREATE USER repl_user;

GRANT REPLICATION SLAVE ON *.* TO repl_user IDENTIFIED BY ‘123456‘;

重启master

4、配置slave

修改/etc/my.cnf增加

[mysqld]
server-id = 2
relay-log-index = slave-relay-bin.index
relay-log slave-relay-bin

重启slave

5、连接master和slave

CHANGER MASTER TO
MASTER_HOST = ‘master-1‘,
MASTER_PORT = 3306,
MASTER_USER = ‘repl_user‘,
MASTER_PASSWORD = ‘123456‘;

START SLAVE;
