linux下mysql集群安装

1.Mysql集群的原理

通过访问虚拟ip值，在主keepalived没有宕机的情况下访问主keepalived的值对应的mysql,主keepalived宕机的情况下访问从keepalived对应的mysql.两个服务器通过虚拟ip关联.

2.Linux上Mysql的安装

 
 1、配置YUM源 

1.yum源配置

      yum install -y 
 https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm 

      查看安装yum源成功 

 
  yum repolist enabled | grep "mysql.*-community.*" 

 
     可以修改 
 vim /etc/yum.repos.d/mysql-community.repo 
 源，改变默认安装的mysql版本。比如要安装5.6版本，将5.7源的enabled=1改 成        enabled=0。然后再将5.6源的enabled=0改成enabled=1即可。改完之后的效果如下所示： 

 
 2、安装MySQL 

 
 shell> yum install mysql-community-server 

 
 3、启动MySQL服务 

 
 shell> systemctl start mysqld 

 
 查看MySQL的启动状态 

 
 shell> systemctl status mysqld● mysqld.service - MySQL Server Loaded: loaded (/usr/lib/systemd/system/mysqld.service; disabled; vendor preset: disabled) Active: active (running) since 五 2016-06-24 04:37:37 CST; 35min ago Main PID: 2888 (mysqld) CGroup: /system.slice/mysqld.service └─2888 /usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid
