用Virtualenv、Circus和chaus288部署Django

Question

我试图在虚拟主机上运行CentOS 7，使用Virtualenv、Circus和chaus结运行Django，但是当我运行circusd circus.ini时，我一直收到这个错误。

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

我的django项目的路径是/opt/webapps/django/.这就是这条道路的结构：

(FYI:设置是我给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

通向我的虚拟环境的路径是：~/.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

my circus.ini的内容如下：

[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。这就是我所做的。

首先，我将我的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，所以我得到了另一个错误：

OSError: [Errno 9] Bad file descriptor

为了找到解决这个问题的方法，我找到了这个修复https://github.com/mozilla-services/circus/pull/800/files

希望这对其他人有帮助。

Answer 2

这个答复是太迟，但可能会对其他人有用。现在与python3.4和django1.9一起工作

这是我的/etc/马戏团/马戏团。

[circus]
check_delay = 5
include_dir = /etc/circus/conf.d
logoutput = /var/log/circus/system.log
statsd = True

[plugin:flapping]
use = circus.plugins.flapping.Flapping

还有我的项目/etc/马戏团/conf.d.D/Project.ini

[project_name]
cmd = chaussette project_name.wsgi.application --backend waitress --fd $(circus.sockets.project_name)
use_sockets = True
virtualenv = /path/to/env  # if you are using virtualenv
working_dir = /path/to/project
copy_env = True

stdout_stream.class = FileStream
stdout_stream.filename = /path/to/logs/stdout.log
stdout_stream.refresh_time = 0.3

stderr_stream.class = FileStream
stderr_stream.filename = /path/to/logs/error.log
stderr_stream.refresh_time = 0.3

[project_name]
PYTHONPATH  = /path/to/project

[socket:project_name]
host = localhost
port = 8000

注意/path/to/log/和/var/log/ Take /system.log上的权限。目录应该存在。
