如何安装Certbot插件？

Question

我通过以下本教程安装了Certbot：

sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
sudo apt-get install python-certbot-nginx

现在我想设置我的证书，但我需要dns-digitalocean插件：

# certbot certonly --dns-digitalocean
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Could not choose appropriate plugin: The requested dns-digitalocean plugin does not appear to be installed
The requested dns-digitalocean plugin does not appear to be installed

我尝试用pip安装它：

pip install certbot-dns-digitalocean

但显然，apt-get版本并没有“看到”它。

如何正确安装？

Answer 1

第一轮

# type certbot
certbot is hashed (/usr/bin/certbot)

找出安装certbot的位置。或者command -v certbot，如果你愿意的话。

然后运行head /usr/bin/certbot并注意它使用的是哪个版本的Python：

#!/usr/bin/python3

在我的例子中，它使用的是Python 3。

我从pip输出中注意到，它试图安装Python2.7包：

# pip install certbot-dns-digitalocean
Requirement already satisfied: certbot-dns-digitalocean in /usr/local/lib/python2.7/dist-packages

那么，我们如何获得pip来安装Python 3软件包呢？只需复制来自这里的说明：

cd /tmp
curl -O https://bootstrap.pypa.io/get-pip.py
python3 get-pip.py
rm get-pip.py

现在您应该有了pip3命令，所以请运行以下命令：

pip3 install certbot-dns-digitalocean

现在再试一次

# certbot plugins
Saving debug log to /var/log/letsencrypt/letsencrypt.log

更好的方法，感谢其他人的回应帮助我做到这一点。

确定当前安装了哪些插件：

# certbot-auto plugins
Saving debug log to /var/log/letsencrypt/letsencrypt.log

Entry point: apache = certbot_apache.entrypoint:ENTRYPOINT

* nginx

Entry point: nginx = certbot_nginx.configurator:NginxConfigurator

* standalone

确定您的certbot (在我的例子中是certbot-auto)安装的位置：

# find / -name certbot
/opt/eff.org/certbot
...

进入虚拟环境并安装插件

cd /opt/eff.org/certbot/venv
source bin/activate
pip install certbot-dns-google
deactivate

再次验证certbot插件

Answer 3

现在(2018年7月)，您应该可以使用

pip install certbot-dns-digitalocean

或

git clone https://github.com/certbot/certbot.git
cd certbot/certbot-dns-digitalocean/
python setup.py install

您可能需要sudo特权。

安装后，您可能无法看到插件与certbot plugins，但您应该能够certbot certonly --dns-digitalocean只是很好。
