我需要帮助设置 LetsEncrypt 的 CertBot
我在 CentOS 7 上运行 Python 2.7
当我运行 certbot 时出现以下错误:

请帮忙

答案1
不要尝试在 CentOS/RHEL 系统上手动安装 certbot。这只会造成很大的混乱。相反,请从 EPEL 安装它。
yum install epel-release
yum install certbot
答案2
在过去 2 个月中,我在 2 个不同的 Centos7 系统上两次遇到过同样的问题。以下是对我有用的方法:
- yum remove pyOpenSSL [这将删除通过 epel 安装的 certbot]
- yum install openssl-devel python-devel [实际上可能需要也可能不需要]
- pip 安装 certbot
- pip 安装 certbot-apache
完成这些步骤后,我就能够使用 certbot 成功更新我的证书。
答案3
我遇到了同样的问题。使用 python venv,我能够使用 pip 让 certbot 运行。
步骤:安装virtualenv
pip install virtualenv --upgrade
创建一个虚拟环境
virtualenv -p /usr/bin/python2.7 certbot
激活certbot
虚拟环境
. /root/certbot/bin/activate
你的提示可能会变成这样
(certbot) [root@hostname ~]#
然后 pip 安装 certbot
pip install certbot
完成后,您可以在虚拟环境certbot
中测试命令certbot
,但如果您要使用 cron 设置 certbot 续订,则这不切实际。因此,请停用虚拟环境,
(certbot) [root@hostname ~]# deactivate
现在从运行 certbot 命令
/root/certbot/bin/certbot
答案4
这对我似乎有用。
