### 一、安装mailx ###

yum install mailx

### 二、编辑`/etc/mail.rc` ###

mailx安装完成后会生成`/etc/mail.rc`文件，打开mail.rc文件，在末尾添加以下内容

#发送邮件的邮箱
    set from=913011***@qq.com
    #smtp邮件服务器
    set smtp=smtp.qq.com
    #发送邮件的邮箱用户
    set smtp-auth-user=913011***@qq.com
    #邮箱授权码
    set smtp-auth-password=cozc********bceb
    set smtp-auth=login
    set ssl-verify=ignore

## ##

### 三、编写邮件通知脚本 ###

创建邮件通知脚本文件`notify.sh`，编辑内容如下

#!/bin/bash
    #接收者邮箱，多个以空格分隔
    contact=(913011***@qq.com 15773241***@163.com )
    #本机ip
    HOST_IP=192.169.1.71
    notify() {
        #邮件主题
        mailsubject="vip转移,$HOST_IP keepalived to be $1"
        #邮件正文
        mailbody="$(date +'%F %T'): vrrp transition, $HOST_IP keepalived changed to be $1"
        for receiver in ${contact[*]}
        do
            #发送邮件
            echo "$mailbody" | mail -s "$mailsubject" $receiver
        done
    }
    case $1 in
    master)
        notify master
        ;;
    backup)
        notify backup
        ;;
    fault)
        notify fault
        ;;
    *)
        echo "Usage:{master|backup|fault}"
        exit 1
        ;;
    esac

编辑完成后，给脚本授予执行权限

chmod +755 notify.sh

手动执行一下脚本./notify.sh master ，看是否可以成功发送邮件

### 四、在keepalived中调用邮件通知脚本 ###

在keepalived的配置文件`keepalived.conf`中配置`notify.sh`脚本被触发执行的时机

#当前节点成为主节点时触发的脚本
    notify_master "/etc/keepalived/notify.sh master"
    #当前节点转为备节点时触发的脚本
    notify_backup "/etc/keepalived/notify.sh backup"
    #当前节点转为失败状态时触发的脚本
    notify_fault "/etc/keepalived/notify.sh fault"
