Shell发送邮件+附件
shell发送邮件,这里以QQ邮箱为发送方进行操作的
1. 生成QQ邮箱授权码
2. 服务器配置
2.1 关闭sendmail的服务
service sendmail status
如果有安装,就关闭sendmail的服务,并关闭开机自启动
service sendmail stop
chkconfig sendmail off
2.2 开启postfix服务
service postfix status
service postfix start
postfix start失败,执行检查命令postfix check
解决:安装mysql-libs
rpm -qa|grep mysql
yum install -y mysql-libs
设置postfix 开机自启动
chkconfig postfix on
2.3 创建认证
mkdir -p /root/.certs/
echo -n | openssl s_client -connect smtp.qq.com:465 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ~/.certs/qq.crt
certutil -A -n "GeoTrust SSL CA" -t "C,," -d ~/.certs -i ~/.certs/qq.crt
certutil -A -n "GeoTrust Global CA" -t "C,," -d ~/.certs -i ~/.certs/qq.crt
certutil -L -d /root/.certs
cd /root/.certs
certutil -A -n "GeoTrust SSL CA - G3" -t "Pu,Pu,Pu" -d ./ -i qq.crt
ll
2.3 配置mail.rc
vi /etc/mail.rc
文件尾部添加下面内容:
set from=131413688@qq.com
set smtp=smtp.qq.com
set smtp-auth-user=131413688
#授权码
set smtp-auth-password=xxxxx
set smtp-auth=login
set smtp-use-starttls
set ssl-verify=ignore
set nss-config-dir=/root/.certs
说明:上面的from、smtp-auth-user换成自己的QQ号,xxxxx替换成第1步生成的授权码
3. 测试
3.1 直接发送普通文字邮件
echo "hello word" | mail -s "title" 131413688@qq.com
接收到的邮件:
3.2 将文件内容作为邮件内容发送
cd /root/data/shell
vim mailContent.txt
文件内容为:
Hello Jack, Nice to meet you.
I'm from shenzhen, China.
执行发送邮件命令
cd /root/data/shell
cat mailContent.txt | mail -s "旅游向导" 131413688@qq.com
接收到的邮件:
3.3 shell发送无附件的邮件
1)编写shell脚本
vim /root/shell/mail/mail_noattachment.sh
文件内容为:
#!/bin/bash
FROM_EMAIL="131413688@qq.com"
TO_EMAIL="100861008@qq.com,100861999@qq.com"
JOB_NAME="TEST"
RUNNINGNUM=1
echo -e "`date "+%Y-%m-%d %H:%M:%S"` : The running $JOB_NAME job num is $RUNNINGNUM in 192.168.137.201 执行异常!!" | mail \
-r "From: alertAdmin <${FROM_EMAIL}>" \
-s "Warn: Skip the new $JOB_NAME spark job." ${TO_EMAIL}
说明:FROM_EMAIL、TO_EMAIL都换成自己的邮箱来测哈!
2)执行shell脚本发送邮件
sh /root/shell/mail/mail_noattachment.sh
接收到的邮件:【我TO_EMAIL里指定的2两个邮箱都收到了邮件】
3.4 Shell发送带附件的邮件
1)准备2个附件:
第一个log日志文件
vim /root/shell/mail/error1.log
文件内容为【加中文可以测试附件是否会中文乱码】:
错误日志1:
This is the exception 1.1...
This is the exception 1.2...
第二个log日志文件
vim /root/shell/mail/error2.log
文件内容为:
错误日志2:
This is the exception 2.1...
This is the exception 2.2...
2)编写shell脚本
vim /root/shell/mail/mail_attachment.sh
文件内容为:
#!/bin/bash
FROM_EMAIL="131413688@qq.com"
TO_EMAIL="100861008@qq.com,100861999@qq.com"
LOG1=/root/shell/mail/error1.log
LOG2=/root/shell/mail/error2.log
echo -e "`date "+%Y-%m-%d %H:%M:%S"` : Please to check the fail sql attachement." | mailx \
-r "From: alertAdmin <${FROM_EMAIL}>" \
-a ${LOG1} \
-a ${LOG2} \
-s "Critical:DSHS fail sql." ${TO_EMAIL}
3)执行shell脚本发送邮件
sh /root/shell/mail/mail_attachment.sh
接收到的邮件:
TO_EMAIL指定的邮箱都收到了带附件的邮件,且附件里的中文并没有乱码。
3.5 Shell发送带附件的邮件(优化)
3.4 虽然实现了发送附件的功能,但邮件标题和发送哪些附件都是写死在shell脚本中的,灵活性不够,难道每次发个邮件还得修改shell脚本?
所以生产上是把邮件标题、发送哪些附件等信息,通过参数传入的。
1)编写shell脚本
vim /root/shell/mail/mail_attachment2.sh
文件内容为:
#!/bin/bash
# $#表示参数个数
if [ $# -lt 2 ]; then
echo "Error:Missing parameters"
echo "Useage: sh mail_attachement.sh <mail-title> <attachment1> <attachment2> ..."
exit 1
fi
FROM_EMAIL="131413688@qq.com"
TO_EMAIL="100861008@qq.com,100861999@qq.com"
#从第2个参数开始,用-a拼出要发送的附件
first=1
attachment=""
for i in "$@"
do
if [ $first -eq 1 ]; then
first=0
else
attachment="$attachment -a $i "
fi
done
echo -e "`date "+%Y-%m-%d %H:%M:%S"` : Please to check the fail sql attachement." | mailx \
-r "From: alertAdmin <${FROM_EMAIL}>" \
$attachment \
-s "$1" ${TO_EMAIL}
注意点:
for i in “$@” 这里有个坑,$@ 带上双引号是将每个参数都看作一份数据,彼此之间是独立的,这样能避免一个带空格的参数被拆分成多个参数的问题。
2)执行shell脚本发送邮件【指定邮件标题时故意带了个空格,哈哈】
sh /root/shell/mail/mail_attachment2.sh "Hadoop HDFS启动失败" /root/shell/mail/error1.log /root/shell/mail/error2.log
接收到的邮件:
