安装配置环境:
os:centos 5.4
mysql:5.5.37
虚拟server1:mysql_master(192.168.40.241)
虚拟server2:mysql_slave(192.168.40.242)
安装Mysql:
可参考解压后的INSTALL-BINARY,如下:
12345678910111213141516 shell> groupadd mysqlshell> useradd -r -g mysql mysqlshell> cd /usr/localshell> tar zxvf /path/to/mysql-VERSION-OS.tar.gzshell> ln -s full-path-to-mysql-VERSION-OS mysqlshell> cd mysqlshell> chown -R mysql .shell> chgrp -R mysql .shell> scripts/mysql_install_db --user=mysqlshell> chown -R root .shell> chown -R mysql data# Next command is optionalshell> cp support-files/my-medium.cnf /etc/my.cnfshell> bin/mysqld_safe --user=mysql &# Next command is optionalshell> cp support-files/mysql.server /etc/init.d/mysql.server
配置mysql_master的Mysql权限:
1 grant all on *.* to user@192.168.40.242 identified by ‘123‘;
配置mysql_slave的/etc/my.cnf:
1、修改server-id=2(mysql_master默认为1,何证server-id的唯一性即可)
2、重启mysql服务
3、登录mysql命令行中执行change master to master_host=‘192.168.40.241‘,master_user=‘user‘,master_password=‘123‘
4、slave start (启动复制线程)
常用的相关命令:
slave start; --启动复制线程
slave stop; --停止复制线程
reset slave; --重置复制线程
show slave status; --显示复制线程的状态
show slave status\G; --显示复制线程的状态(分行显示)
show master status\G; --显示主数据库的状态(分行显示)
show master logs --显示主数据库日志,需在主数据库上运行
change master to; --动态改变到主数据库的配置
show processlist --显示有哪些线程在运行
