## 1、在keepalived配置文件中添加配置 ##

在/etc/keepalived/keepalived.conf文件中配置当前节点成为备节点时触发`/usr/local/sendmail.sh`脚本

## 2、编写邮件通知脚本`/usr/local/sendmail.sh` ##

#! /usr/bin/perl -w
    use Net::SMTP_auth; use strict; #smtp服务器
    my $mailhost = 'smtp.qq.com'; #发送邮件的邮箱
    my $mailfrom = '913011***@qq.com'; #接收邮件的邮箱，可填多个
    my @mailto = ('15773241***@163.com','913011***@qq.com'); #邮件主题
    my $subject = 'keepalived up on backup'; #邮件正文
    my $text = '通知内容'; #发送邮件的邮箱用户
    my $user = '913011***@qq.com'; #发送邮件的邮箱的授权码
    my $passwd = 'cozc********bceb'; &SendMail(); sub SendMail(){ my $smtp = Net::SMTP_auth->new($mailhost,Timeout => 120,Debug =>1) or die "Error .\n"; $smtp->auth('LOGIN',$user,$passwd); foreach my $mailto(@mailto){ $smtp->mail($mailfrom); $smtp->to($mailto); $smtp->data(); $smtp->datasend("To:$mailto\n"); $smtp->datasend("From:$mailfrom\n"); $smtp->datasend("Subject:$subject\n"); $smtp->datasend("\n"); $smtp->datasend("$text\n\n"); $smtp->dataend(); } $smtp->quit; }

授予脚本可执行权限

chmod +755 sendmail.sh

## **3、需要安装Net::SMTP\_auth** ##

send\_mail.sh脚本使用Perl编写，需要安装环境：

yum -y install perl-CPAN
    cpan Net::SMTP_auth

依赖环境安装完成后手动执行一下脚本，看是否可以成功发送邮件

./usr/local/sendmail.sh
