收到提醒:
站点每日情况-存在异常
[xxx小程序](
http://xxx/admin/login/?next=/admin/)
证书即将过期:12天后过期
证书快过期了哦
是不是自动续签的脚本没生效啊
去看看什么情况
http://xxx/admin/login/?next=/admin/
登录后:
站点管理 | Django 站点管理员
去找
xxx
的后台服务器
然后去看看证书的事情
关于证书,之前的说法是:
【如果需要】更新证书
当证书过期后,去更新
cd /root/xxx
source renew_cert.sh
那去看看:
renew_cert.sh
以及:cron的任务中,是否有这个自动续签
root@VM-158-80-ubuntu:~/xxx# cat renew_cert.sh 
#!/bin/bash

cd /root/xxx/
python acme_tiny.py --account-key account.key --csr domain.csr --acme-dir /root/xxx/challenges/ > signed.crt || exit
wget -O - https://letsencrypt.org/certs/lets-encrypt-x3-cross-signed.pem > intermediate.pem
cat signed.crt intermediate.pem > chained.pem
nginx -s reload
renew_cert.sh是个bash脚本,是去续签的
然后去看看定时任务中是否有这个
root@VM-158-80-ubuntu:~/xxx# cron
cron     crontab  
root@VM-158-80-ubuntu:~/xxx# crontab -e
*/20 * * * * /usr/sbin/ntpdate ntpupdate.tencentyun.com >/dev/null &
*/1 * * * * /usr/local/qcloud/stargate/admin/start.sh > /dev/null 2>&1 &
0 4 * * 0 /root/xxx/renew_cert.sh >/dev/null 2>&1
0 0 * * * /usr/local/qcloud/xxx/xxx > /dev/null 2>&1 &
~                                                                     
很明显,此处是有:
0 4 * * 0 /root/xxx/renew_cert.sh >/dev/null 2>&1
的,然后去:
【已解决】Linux中crontab的语法和含义
不过发现,是笔误:
root@VM-158-80-ubuntu:~/xxx# ll /root/xxx/renew_cert.sh
ls: cannot access '/root/xxx/renew_cert.sh': No such file or directory
root@VM-158-80-ubuntu:~/xxx# ll /root/xxx/renew_cert.sh 
-rw-r--r-- 1 root root 304 Aug 21  2018 /root/xxx/renew_cert.sh
所以需要去改为:
0 4 * * 0 /root/xxx/renew_cert.sh >/dev/null 2>&1
crontab -e
去编辑为:
# crontab -l
*/20 * * * * /usr/sbin/ntpdate ntpupdate.tencentyun.com >/dev/null &
*/1 * * * * /usr/local/qcloud/stargate/admin/start.sh > /dev/null 2>&1 &
0 4 * * 0 /root/xxx/renew_cert.sh >/dev/null 2>&1
0 0 * * * /usr/local/qcloud/xxx/xxx > /dev/null 2>&1 &
然后先去手动运行试试效果
# /root/xxx/renew_cert.sh
-bash: /root/xxx/renew_cert.sh: Permission denied
root@VM-158-80-ubuntu:~/xxx# sudo /root/xxx/renew_cert.sh
sudo: /root/xxx/renew_cert.sh: command not found
加上sudo sh才行:
# sudo sh /root/xxx/renew_cert.sh

然后此处还要去
【已解决】CentOS中如何查看Let’s Encrypt的ssl证书的过期时间
顺带把此处所有的证书文件都去看看对应过期时间是多少

看起来是:
上述命令:
sudo sh /root/xxx/renew_cert.sh
更新了这几个文件:
  • chained.pem
  • signed.crt
【后记 20191108】
又提示快要过期了:
别人建议:你可以签一个一年有效期的,会省事些
但是此处发现,貌似此处续签Let’s Encrypt只能一次续签3个月
不支持1年
root@VM-158-80-ubuntu:~/xxx# openssl x509 -dates -noout < /root/xxx/intermediate.pem
notBefore=Mar 17 16:40:46 2016 GMT

notAfter=Nov 21 10:43:39 2019 GMT
此处虽然有:
root@VM-158-80-ubuntu:~/xxx# crontab -l
*/20 * * * * /usr/sbin/ntpdate ntpupdate.tencentyun.com >/dev/null &
*/1 * * * * /usr/local/qcloud/stargate/admin/start.sh > /dev/null 2>&1 &
0 4 * * 0 /root/xxx/renew_cert.sh >/dev/null 2>&1
0 0 * * * /usr/local/qcloud/xxx/xxx.sh > /dev/null 2>&1 &
但是貌似没生效?
所以还是手动执行一次

确认已经更新延长过期时间了:
root@VM-158-80-ubuntu:~/xxx# openssl x509 -dates -noout < /root/xxx/chained.pem
notBefore=Nov  8 14:06:43 2019 GMT
notAfter=Feb  6 14:06:43 2020 GMT
顺带再去看看:
【已解决】Ubuntu中crontab的脚本任务没有执行
TODO:
虽然已确认cron中任务生效了。
但是也还是去在:
0 4 1 */2 *
的最近一次运行的时间:
2019-12-01 04:00:00
之后,去看看ssl证书是否已更新:
openssl x509 -dates -noout < /root/xxx/chained.pem
如果的确已更新,才说明此处crontab任务的确真的正常运行了。
否则就还是有问题,再去想办法看日志找原因,去解决。
