项目需要对mysql的状态及性能进行监控。监控的指标包含是否存活、慢查询数、连接数、内存占用等指标。

shell脚本代码如下所示:(没有涉及发送邮件代码,可根据具体需求添加邮件发送代码)

shell 发送告警邮件

利用linux自带的mail命令

修改配置文件 vim /etc/mail.rc

在文件最后添加如下参数

set from=120700@qq.com//发送邮件的邮箱
#set smtp=smtp.qq.com
set smtp.exmail.qq.com
set smtp-auth-user=120700@qq.com//用户
set smtp-auth-password=nmwjxtkdyoqifehbxx//校验码需要根据发送邮件邮箱填写 网页QQ邮箱->设置->账户(开启IMAP/SMTP服务)点击生成授权码
set smtp-auth=login


mail 命令发送邮件 

echo "test3" | mail -s "test" 1207016200@qq.com

php 发送邮件


PHPMailer 是一个封装好的 PHP 邮件发送类,支持发送 HTML 内容的电子邮件,以及可以添加附件发送,并不像 PHP 本身 mail() 函数需要服务器环境支持,您只需要设置邮件服务器以相关信息就能实现邮件发送功能。

理由PHPMailer发送邮件

PHPMailer 项目地址:https://github.com/PHPMailer/PHPMailer

mysql监控 php&<a href=amp;&shell 发送电子邮件" src="" alt="">

【基础代码】


// 引入PHPMailer的核心文件
require_once("PHPMailer-master/src/PHPMailer.php");
require_once("PHPMailer-master/src/SMTP.php");
// 实例化PHPMailer核心类
$mail = new PHPMailer\PHPMailer\PHPMailer();
// 是否启用smtp的debug进行调试 开发环境建议开启 生产环境注释掉即可 默认关闭debug调试模式
$mail->SMTPDebug = 1;
// 使用smtp鉴权方式发送邮件
$mail->isSMTP();
// smtp需要鉴权 这个必须是true
$mail->SMTPAuth = true;
// 链接qq域名邮箱的服务器地址
$mail->Host = 'smtp.qq.com';
// 设置使用ssl加密方式登录鉴权
$mail->SMTPSecure = 'ssl';
// 设置ssl连接smtp服务器的远程服务器端口号
$mail->Port = 465;
// 设置发送的邮件的编码
$mail->CharSet = 'UTF-8';
// 设置发件人昵称 显示在收件人邮件的发件人邮箱地址前的发件人姓名
$mail->FromName = '发件人昵称';
// smtp登录的账号 QQ邮箱即可
$mail->Username = '120700@qq.com';
// smtp登录的密码 使用生成的授权码
$mail->Password = 'nmwjxtkdyoqixxxx';
// 设置发件人邮箱地址 同登录账号
$mail->From = '120700@qq.com';
// 邮件正文是否为html编码 注意此处是一个方法
$mail->isHTML(true);
// 设置收件人邮箱地址
$mail->addAddress('120700@qq.com');
// 添加多个收件人 则多次调用方法即可
$mail->addAddress('123456@163.com');
// 添加该邮件的主题
$mail->Subject = '邮件主题';
// 添加邮件正文
$mail->Body = '<h1>Hello World</h1>';
// 为该邮件添加附件
$mail->addAttachment('./example.pdf');
// 发送邮件 返回状态
$status = $mail->send();

【封装方法】
