一.python邮件发送脚本

1.linux服务器发送邮件，许多人会直接用mail命令发送，虽然可以发送成功，但是许多都会被互联网邮箱当初垃圾邮件处理

2.mutt和msmtp相关于linux下的邮件客户端，和windows上的outlook,foxmail之类有点类似

3.安装mutt和msmtp虽然可以，但是通过python脚本也可以代替，如下

ubuntu@ubuntu:/etc/nagios3/scripts$ cat sendmail

#!/usr/bin/python

import smtplib

import string

import sys

import getopt

def usage():

print """sendmail is a send mail Plugins

Usage:

sendmail [-h|--help][-t|--to][-s|--subject][-m|--message]

Options:

--help|-h)

print sendmail help.

--to|-t)

Sets sendmail to email.

--subject|-s)

Sets the mail subject.

--message|-m)

Sets the mail body

Example:

only one to email  user

./sendmail -t 'eric@nginxs.com' -s 'hello eric' -m 'hello eric,this is sendmail test!

many to email  user

./sendmail -t 'eric@nginxs.com,yangzi@nginxs.com,zhangsan@nginxs.com' -s 'hello eric' -m 'hello eric,this is sendmail test!"""

sys.exit(3)

try:

options,args = getopt.getopt(sys.argv[1:],"ht:s:m:","--help --to= --subject= --message=")

except getopt.GetoptError:

usage()

for name,value in options:

if name in ("-h","--help"):

usage()

if name in ("-t","--to"):

# accept message user

TO = value

TO = TO.split(",")

if name in ("-s","--title"):

SUBJECT = value

if name in ("-m","--message"):

MESSAGE = value

MESSAGE = MESSAGE.split('\\n')

MESSAGE = '\n'.join(MESSAGE)

#smtp HOST

HOST = "smtp.126.com"      （这个是126的smtp服务域名）

#smtp port

PORT = "25"                 （126邮箱smtp端口号）

#FROM mail user

USER = 'Czar_test'      （你注册126邮箱的用户名）

#FROM mail password

PASSWD = 'test123'       （你注册126邮箱的密码）

#FROM EMAIL

FROM = "Czar_test@126.com"   （你的126邮箱地址）

try:

BODY = string.join((

"From: %s" % FROM,

"To: %s" % TO,

"Subject: %s" % SUBJECT,

"",

MESSAGE),"\r\n")

smtp = smtplib.SMTP()

smtp.connect(HOST,PORT)

smtp.login(USER,PASSWD)

smtp.sendmail(FROM,TO,BODY)

smtp.quit()

except:

print "UNKNOWN ERROR"

print "please look help"

print "./sendmail -h"

然后测试发送邮件

ubuntu@ubuntu:/etc/nagios3/scripts$ /etc/nagios3/scripts/sendmail -t "yongkang_tian@126.com" -s "Nagios Test" -m "Hello Wrold"

二.nagios命令文件里面添加代码

ubuntu@ubuntu:/etc/nagios3$ vim commands.cfg

define command{

command_name    notify-host-by-email

command_line    /etc/nagios3/scripts/sendmail  -t $CONTACTEMAIL$ -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" -m "%b" -m "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n"

}

define command{

command_name    notify-service-by-email

command_line    /etc/nagios3/scripts/sendmail -t $CONTACTEMAIL$ -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" -m "%b" -m "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$\n"

}
