nagios使用gmail发送邮件取mysql数据库的字段并邮件通知-白红宇

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 mlnagios@gmail.com -t qwujhq@126.com -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

get download

make make (implies get)

clean make clean

look open subshell in these dists' directories

Other

h,? display this menu ! perl-code eval a perl command

o conf [opt] set and query options q quit the cpan shell

reload cpan load CPAN.pm again reload index load newer indices

autobundle Snapshot force cmd unconditionally do cmd

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

Database was generated on Tue, 28 Jul 2009 00:27:00 GMT

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

Cannot determine perl version info from lib/Net/SSLeay.pm

Cannot determine license info from lib/Net/SSLeay.pm

*** Found OpenSSL-0.9.7a installed in /usr

*** Be sure to use the same compiler and options to compile your OpenSSL, perl,

and Net::SSLeay. Mixing and matching compilers is not supported.

Do you want to run external tests?

These tests *will* *fail* if you do not have network connectivity. [n] y

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 mlnagios@gmail.com -t qwujhq@126.com -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

# 'notify-host-by-email' command definition

define command{

command_name notify-host-by-email

command_line /usr/local/bin/sendEmail/sendEmail -f mlnagios@gmail.com -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:$HOSTOUTPUT$"

}

# 'notify-service-by-email' command definition

define command{

command_name notify-service-by-email

command_line /usr/local/bin/sendEmail/sendEmail -f mlnagios@gmail.com -t $CONTACTEMAIL$ -s smtp.gmail.com -xu mlnagios -xp 34 -o tls=yes -u " ****** Nagios ****** " -m " ** $NOTIFICATIONTYPE$ Service Alert: $HOSTNAME$/$HOSTADDRESS$ $SERVICEDESC$ is $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$ Additional Info:$SERVICEOUTPUT$ $CONTACTPAGER$"

}

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 "jairus@xxx.com qwujhq@xx.com heaventxxx@xxx.com"

do

/usr/local/bin/sendEmail/sendEmail -f mlnagios@gmail.com -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/
