nagios使用gmail发送邮件 取mysql数据库的字段并邮件通知

sendEmail 使用 tls 发送邮件

  开始使用 nagios 时对于 perl 不太了解，在搜索到 sendEmail 后，这款工具使用相同的简单

./sendEmail -f 发送邮件地址 -t 接收邮件地址 -s 发送邮件的 SMTP 服务地址 -u 标题  -xu 用户名 -xp 用户密码 m 发送内容 ；现在开始学习使用 perl 相关知识了，了解相关 perl 模块安装后开始着手使用 gmail 免费邮发送邮件，因为 gmail 免费邮都是使用 ssl 加密的，发送时需带 -o tls=yes 选项都知道是是使用 ssl 了就选择 yes 了 , 其它免费邮如 tom,126 的好像不行

./sendEmail -f [email protected] -t [email protected] -u "this is title" -m "this is my first to mail you "  -s smtp.gmail.com -xu mlnagios -xp 34 -o tls=yes

如果在此系统你未安装过 perl 模块，会报

Jul 17 01:25:35 localhost sendEmail[20965]: ERROR => No TLS support!  SendEmail can't load required libraries. (try installing Net::SSLeay and IO::Socket::SSL)

这个错误，下面来动手安装下 perl 相关模块吧，我这里讲是利用 cpan 下载相关模块然后把模块放到相关 perl 路径下安装，当然你也可以在第一次使用 cpan 时设定 cpan 的路径，我这人比较懒，一路回车过去了，因为我这里只是想要这两个包传到别的地方去安装。

[root@localhost Net-SSLeay-1.35]# perl -MCPAN -e shell

使用这个命令进入 cpan

进入后使用 h 查看帮助

cpan> h

使用 get 下载相关模块

cpan> get  Net::SSLeay

cpan> get IO::Socket::SSL

下载完成后会提示你下载在哪个目录下

我这个是下好了再次使用下载命令时会提示你已经在下载目录下有了

cpan> get IO::Socket::SSL

CPAN: Storable loaded ok

Going to read /root/.cpan/Metadata

Running get for module IO::Socket::SSL

CPAN: Digest::MD5 loaded ok

Checksum for /root/.cpan/sources/authors/id/S/SU/SULLR/IO-Socket-SSL-1.27.tar.gz ok

进入相关目录查看

[root@localhost sendEmail-v1.55]# cd /root/.cpan/sources/authors/id/S/SU/SULLR/

[root@localhost SULLR]# ls

CHECKSUMS  IO-Socket-SSL-1.27.tar.gz

好了，两包都下好了，把相关传你想在哪台机器上实现发 mail 功能

找到 perl 安装模块的路径

我这里是 /usr/lib/perl5/5.8.5/

这些模块的安装就比较简单了，使用 more 查看安装帮助

[root@localhost Net-SSLeay-1.35]# more README

这是 Net::SSLeay 的后面 perldoc 应该可以明白吧

         ./Makefile.PL -t     # builds and tests it

         make install         # You probably have to su to root to do this

         perldoc Net::SSLeay  # optional, but highly recommended

         perldoc Net::SSLeay::Handle

 

这个安装 IO::Socket::SSL 的

 

         perl Makefile.PL

         make

         make test

         make install

 

[root@localhost Net-SSLeay-1.35]# ./Makefile.PL -t

Writing Makefile for Net::SSLeay

 [root@localhost Net-SSLeay-1.35]# make install

进入放置 sendEmail 程序的目录

[root@localhost sendEmail-v1.55]# pwd

/root/sendEmail-v1.55

[root@localhost sendEmail-v1.55]# ./sendEmail -f [email protected] -t [email protected] -u "this is title" -m "this is my first to mail you "  -s smtp.gmail.com -xu mlnagios -xp 1234 -o tls=yes

Jul 21 13:17:04 localhost sendEmail[10764]: Email was sent successfully!

好了邮件发送成功

define command{

        command_name    notify-host-by-email

        command_line     /usr/local/bin/sendEmail/sendEmail -f [email protected] -t $CONTACTEMAIL$  -s smtp.gmail.com -xu mlnagios -xp 34 -o tls=yes -u "****** Nagios ******" -m " ** $NOTIFICATIONTYPE$ Service Alert: $HOSTNAME$/$HOSTADDRESS$  is $HOSTSTATE$ at \n\nDate/Time: $LONGDATETIME$ Additional Info:$HOSTOUTPUT$"

        }

 

数据库相关字段通知脚本，如下取得数据库相关脚本，然后发邮件通知相关联系人

#!/bin/bash

#get the database field

field=`mysql -uroot --password=xxxxxx <<QUERY_SQL

         select last from qeedoo.tbl_sch_account where email="test1";

         QUIT

         QUERY_SQL`

#define CONTACTEMAIL

for mail in "[email protected] [email protected] [email protected]"

do

/usr/local/bin/sendEmail/sendEmail -f [email protected] -t $mail  -s smtp.gmail.com -xu mlnagios -xp xxx -o tls=yes  -u " ****** THE NOTICE FOR MYSQL  ****** " -m "$field"

Done

最后自己定义下 crontab 定时查询一下，如果需要更智能些自己调整，呵呵，sendEmail可以从这里下载http://caspian.dotconf.net/menu/Software/SendEmail/
