正在寻找一种方法让 certbot 在 Amazon Linux 2 上运行

亚马逊推出了一款名为“Amazon Linux 2”的新 Linux

当我尝试让 certbot 运行时......

 wget https://dl.eff.org/certbot-auto
 chmod a+x certbot-auto
 ./certbot-auto

给出了这个错误

Sorry, I don't know how to bootstrap Certbot on your operating system!

You will need to install OS dependencies, configure virtualenv, and run pip install manually.
Please see https://letsencrypt.readthedocs.org/en/latest/contributing.html#prerequisites for more info.

然后我尝试：

yum install pip
yum install python-pip
pip install cryptography 
pip install certbot
yum install python-urllib3
yum install augeas
/usr/bin/certbot

我收到了这条消息

Traceback (most recent call last):
  File "/usr/bin/certbot", line 7, in <module>
    from certbot.main import main
  File "/usr/lib/python2.7/site-packages/certbot/main.py", line 19, in <module>
    from certbot import client
  File "/usr/lib/python2.7/site-packages/certbot/client.py", line 11, in <module>
    from acme import client as acme_client
  File "/usr/lib/python2.7/site-packages/acme/client.py", line 34, in <module>
    import urllib3.contrib.pyopenssl  # pylint: disable=import-error
  File "/usr/lib/python2.7/site-packages/urllib3/contrib/pyopenssl.py", line 50, in <module>
    from ndg.httpsclient.ssl_peer_verification import SUBJ_ALT_NAME_SUPPORT
ImportError: No module named ndg.httpsclient.ssl_peer_verification

我不知道接下来该怎么做。任何建议我都会非常感激！

答案1

我也遇到了这个问题，因为 Amazon Linux 2 在其存储库中没有这个epel-release，但我发现你可以安装 EPEL RPM 包本身，然后你就可以从那里安装certbot或。certbot-nginx

  • 下载 RPM

    curl -O http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

  • 然后安装

    sudo yum install epel-release-latest-7.noarch.rpm

  • 现在你可以安装 certbot

    sudo yum install certbot

  • 然后照常运行

    sudo certbot

查看certbot 页面之后获取配置详细信息。

除了 Certbot，您还可以使用巅峰，它有效且文档齐全。我有一个关于在 Amazon Linux 上设置 Let's Encrypt 的教程这里。

Nginx 配置

在颁发证书之前，Let's Encrypt 需要调用服务器来验证请求。Acmetool 可以使用其内置的 Web 服务器或外部 Web 服务器。这是我的 Nginx 配置，它与为网站其余部分提供服务的安全服务器块并列。

# This server directly serves ACME / certificate redirects. All other requests are forwarded the https version of the page
server {
  listen 80;
  server_name example.com;
  access_log /var/log/nginx/access.log main;

  # Let's Encrypt certificates with Acmetool
    location /.well-known/acme-challenge/ {
    alias /var/www/.well-known/acme-challenge/;
  }

  location / {
    return 301 https://www.photographerstechsupport.com$request_uri;
  }
}

Nginx 文件夹

mkdir -p /var/www/.well-known/acme-challenge
chmod -R user:www-data /var/www/acme-challenge/*
find /var/www/acme-challenge/ -type d -exec chmod 755 {} \;
vi /var/www/acme-challenge/.well-known/acme-challenge/text.html   (add "hello world" or similar)

安装 Acme

sudo -i   (this is run as root)
cd /opt
wget https://github.com/hlandau/acme/releases/download/v0.0.62/acmetool-v0.0.62-linux_386.tar.gz (NB check for newer versions here)
tar -xzf acmetool-v0.0.62-linux_386.tar.gz
cd acmetool-v0.0.62-linux_386/bin
cp ./acmetool /usr/local/bin
/usr/local/bin/acmetool quickstart

在快速入门中输入此内容作为你的 webroot

/var/www/.well-known/acme-challenge/

申请证书

/usr/local/bin/acmetool want example.com www.example.com

故障排除 #1

acmetool --xlog.severity=debug > /tmp/dump 2>&1 want example.com www.example.com
fgrep -v fdb: /tmp/dump | fgrep -v storageops: > /tmp/dumpout

我的博客文章中还有其他故障排除技巧。
