# [mysql架构精选][mysql] #

◆主从架构  
1.安装服务（主从）  
yum -y install mysql\*  
/etc/init.d/mysqld start  
2.修改配置文件:/etc/my.conf(主从)  
vi /etc/my.conf  
log-bin=mysql-bin \#\#\#开启二进制日志文件  
server-id=131 \#\#\#声明服务器ID，不重复即可  
/etc/init.d/mysqld restart  
3.1进入主—数据库  
mysqladmin -uroot password '123'  
mysql -uroot –p  
\#\#创建从服务器登录用户  
\#\#grant replication slave on \*.\* to '用户'@'%' identified by '密码';  
grant replication slave on \*.\* to 'master'@'%' identified by '123';  
show master status; \#\#查看二进制文件名，以及大小  
3.2进入从-数据库  
mysqladmin -uroot password '123'  
mysql -uroot –p  
\#\#确定从主服务器同步  
\#\#change master to master\_host='主服务器IP',master\_user='用户',master\_password='密码',master\_log\_file='二进制文件',master\_log\_pos=文件空间大小;  
change master to master\_host='192.168.116.131',master\_user='master',master\_password='123',master\_log\_file='mysql-bin.000001',master\_log\_pos=385;  
\#\#启动同步  
start slave;  
\#\#查看同步服务开启状态  
show slave status\\G;  
4.测试  
主：create database aa;  
从：show databases;
