Ghost 博客 SSL 证书过期的解决办法

## 问题 ##

今天访问我的 [Ghost 博客][Ghost] 的时候，发现进不去了：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTAwOTkwODA_size_16_color_FFFFFF_t_70]  
*网上找的图，不过就是这个样子，当时忘了截图*

点击 `高级` 也没有进去的链接，而且页面地址前面写着”不安全“，证书显示也已经过期一个月了。而且我自己部署的 flask 服务也访问不了了。

## 原因 ##

Ghost 本身其实会自动 renew 证书，可使用如下命令查看定时任务：

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

有这个输出就表示会自动 renew。但是根据网上的说法，Ghost 没有及时升级 `/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"

自动升级默认是被注释掉的，不过我也不能百分比确定取消注释就会自动升级。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**升级 `[acme.sh](http://acme.sh)` 然后重启 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.  升级：
    
        $ 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] 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.  升级后的文件是放在 home 目录下的，所以要 cp 过来：
    
        $ sudo cp ~/.acme.sh/acme.sh .
5.  手动执行一次定时任务。注意加上 --force，原因：[sudo · acmesh-official/acme.sh Wiki][sudo _ acmesh-official_acme.sh Wiki]

        [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

然后，就又可以看到安全的小白锁了，证书也有效了：

## 彩蛋 ##

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

> ”thisisunsafe“：这是我见过的最神奇最离奇的操作了，没有之一。当你遇到”您的连接不是私密连接“错误的时候，直接在当前页面”凭空“输入这个字符串，就可以进去页面了。注意是凭空，不是地址栏，你看不到你所输入的东西。[\#有用而有趣的冷知识][Link 1][https://t.co/TnZ5a5o5LN][https_t.co_TnZ5a5o5LN]

即，当你遇到“您的连接不是私密连接”错误的时候，直接在当前页面“**凭空**”输入 `thisisunsafe`，就可以进去页面了。注意是凭空，不是地址栏，你是看不到你所输入的东西的。

而且根据 [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。
