本文记录了在CentOS 7上使用Certbot安装LetsEncrypt SSL证书时遇到的问题及解决方案，特别是解决了因pyOpenSSL版本过低导致的安装失败。

我们用的是letsencrypt的证书

letsencrypt

1.安装certbot

certbot
然后进去之后选择软件和系统

笔主的是centos7的，然后就直接yum安装

sudo yum install python-certbot-apache

然后

certbot --apache

但是笔主这里报了个错：

[root@VM_37_3_centos ~]# certbot --apache
Traceback (most recent call last):
  File "/usr/bin/certbot", line 9, in <module>
    load_entry_point('certbot==0.11.1', 'console_scripts', 'certbot')()

他说这个pyOpenssl必须要v0.14以上

我们看一下这个现有：

[root@VM_37_3_centos ~]# pip show pyOpenssl
Name: pyOpenSSL
Version: 0.13.1
Summary: Python wrapper module around the OpenSSL library
Home-page: http://pyopenssl.sourceforge.net/
Author: Jean-Paul Calderone
Author-email: exarkun@twistedmatrix.com
License: APL2
Location: /usr/lib64/python2.7/site-packages
Requires:

是0.13的。。。。醉了

好吧，卸载了重新装

pip uninstall pyOpenssl

[root@VM_37_3_centos ~]# pip uninstall pyOpenssl
DEPRECATION: Uninstalling a distutils installed project (pyOpenssl) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
Uninstalling pyOpenSSL-0.13.1:
  /usr/lib64/python2.7/site-packages/pyOpenSSL-0.13.1-py2.7.egg-info
Proceed (y/n)? y
  Successfully uninstalled pyOpenSSL-0.13.1

然后我们就卸载完毕了

装吧

pip install pyOpenssl

然后果然不出所料报错了
