mysql keepalived安装配置步骤

//keepalived安装配置步骤

1. 安装keepalived步骤（server6、 server7上都要安装）：

 

wget http://www.keepalived.org/software/keepalived-1.1.19.tar.gz

tar zxvf keepalived-1.1.19.tar.gz

 

cd keepalived-1.1.19

yum -y install openssl-devel

./configure --prefix=/usr/local/keepalived

make

make install

cp /usr/local/keepalived/sbin/keepalived /usr/sbin/

cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/

cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/

mkdir /etc/keepalived

cd /etc/keepalived/

 

2. keepalived的配置

配置server6的keepalived配置文件/etc/keepalived/keepalived.conf（/etc/keepalived/里面没有文件，需要新编辑一个）

 

vi /etc/keepalived/keepalived.conf

bal_defs {

       notification_email {

              [email][e-mail][/email]

       }

       notification_email_from[email][e-mail][/email]

       smtp_server 127.0.0.1

       smtp_connect_timeout 30

       router_id test1

}

 

 

vrrp_instance VI_1 {

       state MASTER

       interface eth1

       virtual_router_id 51

       priority 100

       advert_int 1

       smtp_alert

       authentication {

               auth_type PASS

               auth_pass 123

       }

 

       virtual_ipaddress {

                192.168.10.170

       }

}

server7的配置：

keepalived配置文件/etc/keepalived/keepalived.conf，内容如下：

vi /etc/keepalived/keepalived.conf

bal_defs {

       notification_email {

              [email][e-mail][/email]

       }

       notification_email_from[email][e-mail][/email]

       smtp_server 127.0.0.1

       smtp_connect_timeout 30

       router_id test2

}

 

 

vrrp_instance VI_1 {

       state MASTER

       interface eth1

       virtual_router_id 51

       priority 80

       advert_int 1

       smtp_alert

       authentication {

               auth_type PASS

               auth_pass 123

       }

 

 

3. 启动keepalived:

在server6、server7上执行如下命令启动：

[root@server6 ~]# /etc/rc.d/init.d/keepalived start   ---OK

Starting keepalived: [ OK  ]

4. 测试

  //启动虚拟的10.170IP通过8066端口连接成功，即表示整个环境搭建成功。

[root@server6 ~]# mysql -uroot -proot -h192.168.10.170 -P8066
