尝试在内部自托管阅读文档，但对 Django 的经验很少。

我已经按照readthedocs上的所有步骤（在我拥有的 /usr/share/ 中创建 virtualenv 并拥有组所有权 www-data）用于开发网络服务器，并且效果很好。

已采取以下附加步骤将 wsgi 和 apache 设置为 selfhost：

  • 安装了额外的依赖

    • sudo apt-get install libapache2-mod-wsgi libpq-dev redis-server
    • cd /usr/share/readthedocs/
    • pip install psycopg2 redis django-redis-cache django-redis-sessions
    • pip install --upgradehiredis

  • 配置redis监听socket并放宽权限到777

apache被配置为一个虚拟主机：

<VirtualHost *:80>
    ServerName docs.vagrant

    WSGIScriptAlias / /usr/share/readthedocs/checkouts/readthedocs.org/readthedocs/wsgi.py
    WSGIProcessGroup www-data
    WSGIDaemonProcess www-data \
    python-path=/usr/share/readthedocs/checkouts/readthedocs.org/readthedocs/:/usr/share/readthedocs/lib/python2.7/site-packages/:/usr/share/readthedocs/:/usr/share/readthedocs/checkouts/readthedocs.org/:/usr/share/readthedocs/lib/python2.7/site-packages/django/db/backends/postgresql_psycopg2/

    <Directory /usr/share/readthedocs/checkouts/readthedocs.org/readthedocs/>
        <Files wsgi.py>
        Require all granted
        </Files>
    </Directory>
</VirtualHost>

并且流量似乎正确地流向了后端。然而，RTD 抱怨缺少 REDIS 属性。Apache 错误日志输出：

我意识到我还需要启用弹性搜索并进行正确配置，但是当我走到那一步时，我会越过那座桥。

更新：发出grep -i redis /usr/share/readthedocs/checkouts/readthedocs.org/readthedocs/settings/*返回的命令

__init__.py:        'BACKEND': 'redis_cache.RedisCache',
__init__.py:            'PARSER_CLASS': 'redis.connection.HiredisParser'
onebox.py:REDIS = {
onebox.py:BROKER_URL = 'redis://localhost:6379/0'
onebox.py:CELERY_RESULT_BACKEND = 'redis://localhost:6379/0'
onebox.py:        'BACKEND': 'redis_cache.cache.RedisCache',
onebox.py:            'CLIENT_CLASS': 'redis_cache.client.DefaultClient',
postgres.py:        'BACKEND': 'redis_cache.RedisCache',
postgres.py:            'PARSER_CLASS': 'redis.connection.HiredisParser'
sqlite.py:REDIS = {
sqlite.py:BROKER_URL = 'redis://localhost:6379/0'
sqlite.py:CELERY_RESULT_BACKEND = 'redis://localhost:6379/0'

所以我重新配置redis不再使用套接字并返回绑定/端口，但问题仍然存在（使用相同的堆栈跟踪）。

好的，现在解决了这个问题。不得不补充：

/usr/share/readthedocs/checkouts/readthedocs.org/readthedocs/settings/

到阿帕奇python-path。

和：

REDIS = { 
    'host': 'localhost',
    'port': 6379,
    'db': 0,
}

到设置中的 postgres.py（来自init .py 的符号链接）

现在对其余缺少的依赖错误进行排序。
