python - Graphite 和 GUnicorn - 配置问题或路径问题

Question

我一直在尝试让 Graphite 通过 GUnicorn 运行(最终通过 nginx 代理)，但是我已经尝试了几乎所有启动应用程序的方法，但无法解决类似于以下的错误。

(graphite)/opt/graphite/conf gunicorn --bind=127.0.0.1:8080 graphite.wsgi:app

我试过在不同的目录(root 目录、conf 目录、webapp 目录等)中运行。我试过使用 gunicorn_django 助手运行。我可以使用开发服务器启动它:opt/graphite/bin/run-graphite-devel-server.py --port=8080/opt/graphite

我已经通过 virtualenv 和 pip 安装了所有东西，并简单地将 graphite.wsgi.example 文件复制到 conf 目录中的 graphite.wsgi。看起来像这样:

(graphite)/opt/graphite/conf cat graphite.wsgi.example
import os, sys
sys.path.append('/opt/graphite/webapp')
os.environ['DJANGO_SETTINGS_MODULE'] = 'graphite.settings'

import django.core.handlers.wsgi

application = django.core.handlers.wsgi.WSGIHandler()

# READ THIS
# Initializing the search index can be very expensive, please include
# the WSGIImportScript directive pointing to this script in your vhost
# config to ensure the index is preloaded before any requests are handed
# to the process.
from graphite.logger import log
log.info("graphite.wsgi - pid %d - reloading search index" % os.getpid())
import graphite.metrics.search
(graphite)/opt/graphite/conf

如有任何帮助，我们将不胜感激。

这无疑是错误的做法，但我遇到了同样的问题，我通过以下方式解决了这个问题:

mv /opt/graphite/conf/graphite.wsgi.example /opt/graphite/webapp/graphite/graphite_wsgi.py
cd /opt/graphite/webapp/graphite
gunicorn graphite_wsgi:application

您的问题可能只是使用“app”而不是变量“application”，所以请先简短说明一下。

祝你好运!
