Shell发送QQ邮件

一、开启QQ邮件四个服务，生成授权码(设置-->账户)

二、服务器邮件配置
1、关闭sendmail服务

#sendmial
service sendmail stop
chkconfig sendmail off

2、启动postfix 服务

[hadoop@hadoop000 ~]$ service postfix status
--------------------------------------------------------------------
[root@hadoop000 ~]# service postfix status
master (pid  2274) is running...
--------------------------------------------------------------------
[root@hadoop000 ~]# chkconfig postfix on

如果postfix start失败报以下错误，请执行

[root@rzdatahadoop002 ~]# postfix check
postfix: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory
--------------------------------------------------------------------
[root@rzdatahadoop002 ~]# rpm -qa|grep mysql
--------------------------------------------------------------------
[root@rzdatahadoop002 ~]# yum install mysql-libs

3、创建认证

[root@hadoop000 ~]# mkdir -p /root/.certs/
--------------------------------------------------------------------
[root@hadoop000 ~]# echo -n | openssl s_client -connect smtp.qq.com:465 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ~/.certs/qq.crt
depth=2 C = US, O = DigiCert Inc, OU = www.digicert.com, CN = DigiCert Global Root CA
verify return:1
depth=1 C = US, O = DigiCert Inc, OU = www.digicert.com, CN = GeoTrust RSA CA 2018
verify return:1
depth=0 C = CN, ST = Guangdong, L = Shenzhen, O = Tencent Technology (Shenzhen) Company Limited, OU = R&D, CN = pop.qq.com
verify return:1
DONE
--------------------------------------------------------------------
[root@hadoop000 ~]# certutil -A -n "GeoTrust SSL CA" -t "C,," -d ~/.certs -i ~/.certs/qq.crt
--------------------------------------------------------------------
[root@hadoop000 ~]# certutil -A -n "GeoTrust Global CA" -t "C,," -d ~/.certs -i ~/.certs/qq.crt
--------------------------------------------------------------------
[root@hadoop000 ~]# certutil -L -d /root/.certs

[root@hadoop000 ~]# cd /root/.certs
--------------------------------------------------------------------
[root@hadoop000 .certs]# certutil -A -n "GeoTrust SSL CA - G3" -t "Pu,Pu,Pu"  -d ./ -i qq.crt
--------------------------------------------------------------------
Notice: Trust flag u is set automatically if the private key is present.
--------------------------------------------------------------------
[root@hadoop000 .certs]# ll
total 80
-rw------- 1 root root 65536 Apr 16 20:04 cert8.db
-rw------- 1 root root 16384 Apr 16 20:04 key3.db
-rw-r--r-- 1 root root  2529 Apr 16 20:04 qq.crt
-rw------- 1 root root 16384 Apr 16 20:04 secmod.db

4、配置mail.rc(改为自己的邮箱)

set from=123456789@qq.com
set smtp=smtp.qq.com
set smtp-auth-user=123456789

#授权码(第一步生成的)
set smtp-auth-password=vszvqerunewxbgcg
set smtp-auth=login
set smtp-use-starttls
set ssl-verify=ignore
set nss-config-dir=/root/.certs

三、测试
1、发送hello word到邮箱

[root@hadoop000 .certs]# echo  "hello word" | mail -s "title" 123456789@qq.com 

四、封装脚本

1、发送纯文本信息邮件

#!/bin/bash 

JOB_NAME="Spark ETL"
FROM_EMAIL="123456789@qq.com"
TO_EMAIL="123456789@qq.com"

RUNNINGNUM=1

echo -e "`date "+%Y-%m-%d %H:%M:%S"` : The current running $JOB_NAME job num is $RUNNINGNUM in `hostname -i` ......" | mail \
-r "From: alertAdmin <${FROM_EMAIL}>" \
-s "Warn: Skip the new $JOB_NAME spark job." ${TO_EMAIL}

2、发送带有附件的邮箱

[root@hadoop000 soul]# touch sparketl.log
[root@hadoop000 soul]# echo "aaa" >> sparketl.log
---------------------------------------------------------------------
[root@hadoop000 soul]# cat mail_attachment.sh 
#!/bin/bash 


FROM_EMAIL="462292793@qq.com"
TO_EMAIL="462292793@qq.com"

LOG=/root/soul/sparketl.log 


echo -e "`date "+%Y-%m-%d %H:%M:%S"` : Please to check the fail log attachement." | mailx \
-r "From: alertAdmin <${FROM_EMAIL}>" \
-a ${LOG} \
-s "Critical:Spark ETL  fail log." ${TO_EMAIL}
-------------------------------------------------------------------------
[root@hadoop000 soul]# sh mail_attachment.sh
