CentOS 通過465端口發送QQ郵件

1.QQ郵箱開啓SMTP並獲取授權碼

進入QQ郵箱，選擇設置-賬戶，開啓如圖兩個SMTP，並獲取授權碼

2.關閉sendmail服務

[root@ruozedata001 ~]# service sendmail stop 
[root@ruozedata001 ~]# chkconfig sendmail off

3.修改/etc/postfix/main.cf

[root@ruozedata001 ~]# vim /etc/postfix/main.cf 
# 默認爲 inet_interfaces = localhost，修改成all
inet_interfaces = all

4.啓動postfix服務

[root@ruozedata001 ~]# service postfix start 
[root@ruozedata001 ~]# chkconfig postfix on 
[root@ruozedata001 ~]# postfix check 
[root@ruozedata001 ~]# systemctl status postfix
# 啓動成功輸出

5.創建認證

[hadoop@ruozedata001 ~]$ mkdir -p ~/.certs/ 
[hadoop@ruozedata001 ~]$ echo -n | openssl s_client -connect smtp.qq.com:465 | sed -ne '/-BEGIN CERTIFICATE -/,/-END [hadoop@ruozedata001 ~]$ CERTIFICATE-/p' > ~/.certs/qq.crt 
[hadoop@ruozedata001 ~]$ certutil -A -n "GeoTrust SSL CA" -t "C,," -d ~/.certs -i ~/.certs/qq.crt 
[hadoop@ruozedata001 ~]$ certutil -A -n "GeoTrust Global CA" -t "C,," -d ~/.certs -i ~/.certs/qq.crt 
[hadoop@ruozedata001 ~]$ certutil -L -d ~/.certs
[hadoop@ruozedata001 ~]$ cd ~/.certs 
[hadoop@ruozedata001 ~]$ certutil -A -n "GeoTrust SSL CA - G3" -t "Pu,Pu,Pu" -d ./ -i qq.crt
# 成功輸出
Notice: Trust flag u is set automatically if the private key is present.

6.配置郵件發送者

[root@ruozedata001 ~]# vim /etc/mail.rc
# 底部添加發送着信息
set from=[email protected]	#郵箱
set smtp=smtps://smtp.qq.com:465 
set smtp-auth-user=1115346515 #QQ號
set smtp-auth-password=********** #剛纔申請的授權碼
set smtp-auth=login
set ssl-verify=ignore
set nss-config-dir=/home/hadoop/.certs # 認證文件路徑，注意根據自己用戶的路徑填寫不要盲目複製

7.測試

[hadoop@ruozedata001 ~]$ echo "郵件正文" | mail -s "郵件主題"  [email protected]

8.實時查看 Linux 日誌

[root@ruozedata001 ~]# tail -f /var/log/maillog

9.生產上使用

9.1 發郵件不不帶附件

EMAILFROM=[email protected]
EMAILTO=[email protected] # 多個接受者用 , 分割
echo -e "`date "+%Y-%m-%d %H:%M:%S"` : The current running $JOB_NAME job num is $RUNNINGNUM in 192.168.137.201 ......" | mail \
-r "From: alertAdmin <${EMAILFROM}>" \
-s "Warn: Skip the new $JOB_NAME spark job." ${EMAILTO}

9.2 發郵件帶附件

echo -e "`date "+%Y-%m-%d %H:%M:%S"` : Please to check the fail sql attachement."|mailx \
-r "From: alertAdmin <${EMAILFROM}>" \
-a error.log \
-s "Critical:KSSH fail sql." ${EMAILTO}
