Ubuntu 12.04 中安装高版本keepalived

一直在用的系统版本是12.04，本次安装keepalived中，默认安装的是1.2.2的版本，需要安装新版本，可以通过下载tar.gz包编译安装，但个人更倾向于使用apt-get install 的方式安装，来避免一些不必要的问题。

添加PPA：

apt-get install python-software-properties
sudo add-apt-repository ppa:keepalived/daily
sudo apt-get update

安装：

apt-get install keepalived

配置实例：
MASTER：

! Configuration File for keepalived

global_defs {
   router_id LVS_DEVEL_SERVER 
}

vrrp_script chk_haproxy {
    script "killall -0 haproxy"
    interval 2 
    weight -2 
}

vrrp_instance vip1 {
    state MASTER
    interface eth0
    virtual_router_id 11 #同网域下该值每一对VRRP之间要区分开
    priority 100
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 9292
    }
    virtual_ipaddress {
        192.168.1.11/24
    }
    track_script {
        chk_haproxy              
    }
}

BACKUP：

! Configuration File for keepalived

global_defs {
   router_id LVS_DEVEL_SERVER
}

vrrp_script chk_haproxy {
    script "killall -0 haproxy"  
    interval 2                   
    weight -2                    
}

vrrp_instance vip1 {
    state BACKUP
    interface eth0
    virtual_router_id 11
    priority 99
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 9292
    }
    virtual_ipaddress {
        192.168.1.11/24
    }
    track_script {               
        chk_haproxy
    }
}

完。
