nagios使用gmail发送邮件 取mysql数据库的字段并邮件通知

简介:
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 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,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

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
 
         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/
