第一部分直接转载摘录JasonMingHao的博客“Cobbler 登录web界面提示报错“Internal Server Error”来说明问题哈
在访问cobbler web界面到时候出现以下提示
ssl的报错日志如下：
[root@Cobbler ~]# tail -f /var/log/httpd/ssl_error_log
[Mon Jan 07 16:24:53.363029 2019] [:error] [pid 3383] [remote 10.0.0.1:212] mod = importlib.import_module(self.SETTINGS_MODULE)

查看cobbler的py配置文件
[root@Cobbler ~]# 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@Cobbler ~]# sed -n '89p' /usr/share/cobbler/web/settings.py
from django.conf.global_settings import TEMPLATE_CONTEXT_PROCESSORS
初步判断应该是pythone-django版本问题
#下载pip.py
wget https://bootstrap.pypa.io/get-pip.py
#调用本地python运行pip.py脚本
python get-pip.py
#安装pip
pip install Django==1.8.9
#查看pip版本号
python -c "import django; print(django.get_version())"
#重启httpd
systemctl restart httpd
最后完美解决

然鹅，
我照着一模一样的做依然报这个错误“Internal Server Error”，没有解决！
但是明明就是这个Django版本的问题，经过仔细查看日志，发现File "/usr/lib64/python2.7/importlib/init.py"中python是2.7，想到我的服务器默认的Python是3.6，这个python版本可能就是不成功的元凶，所以就想着切换系统的Python 版本：
sudo mv /usr/bin/python /usr/bin/python_backup_20190314 #把默认版本的Python移开保存
sudo ln -s /usr/bin/python2.7 /usr/bin/python #把python2.7版本设置为默认版本
所以我就想着重新安装下django吧：
[root@localhost /]# pip uninstall Django
Traceback (most recent call last):
File "/usr/local/bin/pip", line 6, in <module>
from pip._internal import main
ImportError: No module named pip._internal
报错pip模块损坏：ImportError: No module named pip._internal
后面一想：pip模块是在python 3.6版本时下载的，包括django也是，既然Python版本换了，所以pip也需要重新安装下，而不仅仅是重装django
所以重新执行之前上面的那套流程即可：
#下载pip.py
wget https://bootstrap.pypa.io/get-pip.py
#调用本地python运行pip.py脚本
python get-pip.py
#安装pip
pip install Django==1.8.9
#查看pip版本号
python -c "import django; print(django.get_version())"
#重启httpd
systemctl restart httpd
OK，这次终于完美解决，哈哈：
