问题： 在访问cobbler web界面到时候出现以下提示
解决步骤：
1. SSL 的报错日志如下：
[root@localhost ~]# tail -f /var/log/httpd/ssl_error_log
[Tue May 28 16:54:16.665181 2019] [:error] [pid 7001] [remote 192.168.1.109:44] self._setup(name)

2. 查看cobbler的py配置文件
[root@localhost ~]# sed -n '38,41p' /usr/share/cobbler/web/settings.py
if django.VERSION[0] == 1 and django.VERSION[1] < 4:
ADMIN_MEDIA_PREFIX = '/media/'
else:
STATIC_URL = '/media/'
[root@localhost ~]# sed -n '89p' /usr/share/cobbler/web/settings.py
from django.conf.global_settings import TEMPLATE_CONTEXT_PROCESSORS
3. 初步判断应该是pythone-django版本问题
##下载get-pip.py
