我在 Hostgator 上读到可以在他们的托管服务上安装 Django ,我已经联系了现场支持并回复说他们无法帮助解决这个问题。

有人已经完成了吗?

可以在HostGator上共享Django。当Django放弃对FastCGI的支持时,这有点棘手。

  • 使用HostGator自己的说明来设置Django。 http://support.hostgator.com/articles/django-with-fastcgi#shared-reseller

  • 但是在它运行之前,你需要将对FastCGI的支持修补回Django。

    • 幸运的是Django在一次提交中删除了FastCGI: https://github.com/django/django/commit/41f0d3d3bc8b0a6831530e1176c6415f9ba45b0b.patch
    • 此修补程序需要反转并移植到指向您拥有的版本。 这种需要检查django源项目并使用git。
    • 不要担心要冲突文档和测试子文件夹,因为无论如何都需要将它们排除在重新FastCGI化修补程序之外。
    • 使用安装在HostGator中的Django版本的补丁文件后,使用git apply将FastCGI支持重新注入虚拟环境中的Django代码 ./mydjango/lib/python2.7/site-packages/django
    • 最后是我最终用于Django版本1.10.1的补丁文件。
  • 使用PyMySQL而不是标准的mysql库。 PyMySQL是一个纯Python的mysql客户端,因为Host Gator不提供gcc。
    • 安装库:pip install PyMySQL
    • 猴子在manage.py和index.fcgi中修补它,在#!之后的两个文件的开头加上以下代码! python line:
#monkey patch importing pymysql
try:
    import pymysql
    pymysql.install_as_MySQLdb()
except ImportError:
    pass

基本步骤是您需要拥有VPS托管http://www.hostgator.com/vps-hosting,您无法在他们的正常托管平台上安装Django,除非他们已经为您完成了。

设置VPS后,您将拥有SSH凭据以登录Linux主机。 (你应该在Windows上使用PuTTY)。一旦将SSH连接到服务器,就可以按照Django教程(https://docs.djangoproject.com/en/1.8/intro/install/)中的说明安装Django。 (以及它的依赖关系)

可以在Windows上开发Django应用程序,但比在Linux主机上开发更困难。这是一个意见。
