关于ghost:Ghost-博客-SSL-证书过期的解决办法

问题

明天拜访我的 Ghost 博客 的时候，发现进不去了：

网上找的图，不过就是这个样子，过后忘了截图

点击 高级 也没有进去的链接，而且页面地址后面写着”不平安“，证书显示也曾经过期一个月了。而且我本人部署的 flask 服务也拜访不了了。

起因

Ghost 自身其实会主动 renew 证书，可应用如下命令查看定时工作：

$ sudo crontab -l
14 0 * * * "/etc/letsencrypt"/acme.sh --cron --home "/etc/letsencrypt" > /dev/null

有这个输入就示意会主动 renew。然而依据网上的说法，Ghost 没有及时降级 /etc/letsencrypt/acme.sh 版本，造成 renew 失败之类的。

我看同目录下的 account.conf 中有一行是这样的：

#AUTO_UPGRADE="1"

主动降级默认是被正文掉的，不过我也不能百分比确定勾销正文就会主动降级。具体我也不是很懂，就不多说了，就提一嘴。

解决

所以总而言之，就是要 降级 acme.sh 而后重启 Ghost。

  1. 进入 acme.sh 目录：

    $ cd /etc/letsencrypt

  2. 备份原文件：

    $ sudo cp acme.sh acme.sh.bk

  3. 降级：

    $ sudo ./acme.sh --upgrade
./acme.sh: line 6192: cd: /home/username/.acme.sh: No such file or directory
[Fri Apr 30 09:47:22 CST 2021] Installing from online archive.
[Fri Apr 30 09:47:22 CST 2021] Downloading https://github.com/Neilpang/acme.sh/archive/master.tar.gz

[Fri Apr 30 09:48:36 CST 2021] It is recommended to install socat first.
[Fri Apr 30 09:48:36 CST 2021] We use socat for standalone server if you use standalone mode.
[Fri Apr 30 09:48:36 CST 2021] If you don't use standalone mode, just ignore this warning.
[Fri Apr 30 09:48:36 CST 2021] Installing to /home/username/.acme.sh
[Fri Apr 30 09:48:36 CST 2021] Installed to /home/username/.acme.sh/acme.sh
[Fri Apr 30 09:48:36 CST 2021] Good, bash is found, so change the shebang to use bash as preferred.
[Fri Apr 30 09:48:37 CST 2021] OK
[Fri Apr 30 09:48:37 CST 2021] Install success!
[Fri Apr 30 09:48:37 CST 2021] Upgrade success!

  4. 降级后的文件是放在 home 目录下的，所以要 cp 过去：

    $ sudo cp ~/.acme.sh/acme.sh .

  5. 手动执行一次定时工作。留神加上 --force，起因：sudo · acmesh-official/acme.sh Wiki

    $ sudo "/etc/letsencrypt"/acme.sh --cron --home "/etc/letsencrypt"

[Fri Apr 30 09:53:32 CST 2021] Reload success
[Fri Apr 30 09:53:32 CST 2021] ===End cron===

  6. 重启 Ghost：

    $ cd /var/www/ghost
$ ghost restart
+ sudo systemctl is-active ghost_northcloudgate-com
+ sudo systemctl restart ghost_northcloudgate-com
✔ Restarting Ghost

而后，就又能够看到平安的小白锁了，证书也无效了：

彩蛋

在 Google”您的连贯不是私密连贯“这个问题的时候，意外发现了一个神奇操作：

即，当你遇到“您的连贯不是私密连贯”谬误的时候，间接在以后页面“凭空”输出 thisisunsafe，就能够进去页面了。留神是凭空，不是地址栏，你是看不到你所输出的货色的。

而且依据 reddit 上的说法，

  • 这个 bypass word 之前是 badidea，再之前是 danger。
  • Chrome 65 的时候把 badidea 改成了 thisisnotsafe 又改成了 thisisunsafe。而且还用 base64 加密了。

此外前文提到的 flask 服务也恢复正常了。

Reference

  • Ghost 博客网站证书过期，怎么办？
  • 事变记录 –SSL 证书过期
  • Chrome 65 replaces the “badidea” bypass keyword with “thisisunsafe” : sysadmin
