mysql 主从复制

以下内容比较简略，权当笔记使用！看到了朋友也可参考其它的博客进行实际操作

[环境简介]
主服务器：192.168.17.123
从服务器：192.168.17.111


[主服务器授权]
1、在主服务器建立一个专门用来主从复制的用户
insert into mysql.user(Host,User,Password) values("%","replication",password("123456"));

2、为该用户授权
语法：
grant 权限1,权限2,…权限n on 数据库名称.表名称 to 用户名@用户地址 identified by ‘连接口令’;
命令：
grant replication slave ON *.* to 'replication'@'%' identified by '123456';

注意：%可以找成相应的从服务器IP
replication slave 此权限可以查看主服务器，要以从主服务器读取二进杂制日志

3、刷新权限表
flush privileges;

[主服务器配置]
log-bin=mysql-bin
server-id=1


mysql> show master status\G;
*************************** 1. row ***************************
            File: mysql-bin.000001
        Position: 107
    Binlog_Do_DB:
Binlog_Ignore_DB:
1 row in set (0.00 sec)



[从数据库配置]
#在mysql命令行下输入：
mysql> change master to master_host='192.168.17.123',master_user='replication',master_password='123456',master_log_file='mysql-bin.000001',master_log_pos=107;

注意：
master_log_file要为主服务器上的log-bin

#启动
mysql> start slave;

#检测从服务器状态
mysql> show slave status\G;
*************************** 1. row ***************************

之后就可以在主数据库中插入删除测试主从复制了！
