IP配置

管理IP地址	角色	备注	网卡
192.168.1.114	主调度器（Director）	对外提供VIP服务的地址为192.168.1.88	eth1
192.168.1.205	备用调度器		eth0
192.168.1.115	RS1
192.168.1.116	RS2

名词解释：

主节点： master

备节点: backup

虚拟路由器冗余协议： VRRP(Virtual Route Redundancy Protocol) ，它的出现是为了解决静态路由的单点故障

2.安装

在主调度器和备用调度器进行同样的安装，不同的是配置文件

安装openssl

yum -y install openssl-devel
tar -xvf keepalived-1.2.15.tar.gz
cd keepalived-1.2.15
./configure --prefix=/usr/local/keepalived --with-kernel-dir=/usr/src/kernels/2.6.32-431.el6.x86_64/
make
make install

配置规范启动

cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/rc.d/init.d/
cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
cp /usr/local/keepalived/sbin/keepalived /usr/sbin/
chkconfig keepalived on

配置配置文件

新建一个配置文件，默认keepalived启动会去/etc/keepalived目录下寻找配置文件

mkdir /etc/keepalived
cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/

编辑主调度器的配置文件

! Configuration File for keepalived

global_defs {
   notification_email {
     zy5724@163.com
   }
   notification_email_from Alexandre.Cassen@firewall.loc
   smtp_server 127.0.0.1
   smtp_connect_timeout 30
   router_id LVS_114
}

vrrp_instance VI_1 {
    state MASTER
    interface eth1
    virtual_router_id 114
    priority 150
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        192.168.1.88
    }
}

从配置文件

! Configuration File for keepalived

global_defs {
   notification_email {
     zy5724@163.com
   }
   notification_email_from Alexandre.Cassen@firewall.loc
   smtp_server 127.0.0.1
   smtp_connect_timeout 30
   router_id LVS_205
}

vrrp_instance VI_1 {
    state BACKUP
    interface eth0
    virtual_router_id 114
    priority 100
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        192.168.1.88
    }
}
