php实现的邮件发送类,nginx的监控

作者: admin 分类: linux,php 发布时间: 2017-07-04 01:56

利用163邮箱提供的邮件发送服务,打开邮件发送服务步骤如下:

1.登录邮箱–>设置–>POP3/SMTP/LMAP

2.将POP3 /SMTP、IMAP/SMTP 服务勾选,过程中会有设置密码,手机验证步骤,简单明了多尝试就可以打开邮件服务了。

服务开启后成功界面

shell每五秒查询下进程,看看nginx服务器是否关闭,如果关闭重启nginx服务器,重启失败向管理者发送邮件

具体代码如下

#!/bin/bash

while :
do
	nginxpid=$(ps -C nginx --no-header | wc -l);
	if [ $nginxpid -eq 0 ];then
		# /etc/init.d/nginx restart
		service nginx restart;
		sleep 5;
		nginxpid=$(ps -C nginx --no-header | wc -l);
		echo $nginxpid;
		if [ $nginxpid -eq 0 ];then
			php sendmail.php
		fi
	fi
	sleep 5;
done
