python - 使用 Virtualenv、Circus 和 Chaussette 部署 Django

Question

我正在尝试在 CentOS 7 的虚拟主机中使用 Virtualenv、Circus 和 Chaussette 运行 Django，但是当我运行 circusd circus.ini 时我不断收到此错误:

(djenv)[root@localhost django]# circusd circus.ini

我的django项目的路径是/opt/webapps/django/。这是该路径的结构:

(仅供引用:settings 是我给我的 django 项目起的名字)

/django/
/django/manage.py
/django/circus.ini
/django/settings/
/django/settings/urls.py
/django/settings/wsgi.py
/django/settings/settings.py

我的 virtualenv 的路径是:~/.virtualenv/djenv/。这是该路径的结构 (bin):

/djenv/
/djenv/bin/
/djenv/bin/circusd
/djenv/bin/chaussette
/djenv/bin/circushttpd
/djenv/bin/python3.4
/djenv/bin/pip

我的 circus.ini 的内容是:

[circus]
endpoint = tcp://127.0.0.1:5555
pubsub_endpoint = tcp://127.0.0.1:5556
stats_endpoint = tcp://127.0.0.1:5557

[watcher:settings]
cmd = ~/.virtualenv/djenv/bin/chaussette django:/opt/webapps/django --fd $(circus.sockets.settings)$ --django-settings settings.settings
use_sockets = True
numprocesses = 3

[socket:settings]
host = 0.0.0.0
port = 8080

Answer 1

所以我终于找到了解决办法。这是我所做的。

首先，我将 circus.ini 更改为:

[circus]
endpoint = tcp://127.0.0.1:5555
pubsub_endpoint = tcp://127.0.0.1:5556
stats_endpoint = tcp://127.0.0.1:5557

[watcher:settings]
cmd = /root/.virtualenvs/djenv/bin/chaussette settings.wsgi.application
args = --fd $(circus.sockets.settings)
use_sockets = True
numprocesses = 3
copy_env = True
virtualenv = /root/.virtualenvs/djenv/

[socket:settings]
host = 0.0.0.0
port = 8080

因为我在 python 3.4.1 中运行这个马戏团我得到了另一个错误:

OSError: [Errno 9] Bad file descriptor

在寻找此问题的解决方案时，我找到了此修复程序 https://github.com/mozilla-services/circus/pull/800/files

希望这对其他人有帮助。
