gunicorn 停止查找 wsgi 目录

gunicorn 停止查找 wsgi 目录

我使用 nginx gunicorn 和 Supervisor 配置了一个 django 应用。几个月来一切都运行良好，直到今天。我没有触碰任何配置文件，但不知何故，502 bad gateway当我尝试访问我网站的任何页面时，我现在得到了响应。

Gunicorn 此处出现错误，以下是其输出的日志：

Traceback (most recent call last):

ModuleNotFoundError: No module named 'inventory4'

我非常困惑，因为之前一切都运行顺利！

这里是我的 gunicorn 的 django 配置：

设置.py：

WSGI_APPLICATION = 'inventory4.wsgi.application'

在 wsgi.py 中：

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'inventory4.settings')

application = get_wsgi_application()

这是我在 /etc/supervisor/conf.d/gunicorn.conf 中的内容

directory=/home/ubuntu/exostocksaas
command=/home/ubuntu/exo/bin/gunicorn  --config /home/ubuntu/exo/lib/python3.6/site-packages/gunicorn/config.py --log-level debug --bind unix:/home/ubuntu/exostocksaas/app.sock inventory4.wsgi:application

autostart=true
autorestart=true
stderr_logfile=/var/log/gunicorn/gunicorn.err.log
stdout_logfile=/var/log/gunicorn/gunicorn.out.log


[group:guni]
programs:gunicorn

这是 gunicorn 包中的 config.py 文件：

BASE_DIR = "/home/ubuntu/"
sys.path.append(BASE_DIR)
 
 
bind = '127.0.0.1:8000'
backlog = 2048
 
 
import multiprocessing
daemon: True
workers = 20
worker_class = 'gevent'
worker_connections = 1000
timeout = 300
graceful_timeout = 300
keepalive = 300
inactivity_timeout=300
errorlog = '-'
loglevel = 'info'
accesslog = '-'
threads = 2

老实说，我刚刚对 django 应用程序进行了更新，所以这很奇怪，有谁知道或经历过可能导致此问题的事情吗？

我现在想到的可能是我的虚拟机遇到了加载问题，这会导致 gunicorn 崩溃吗？以下是我运行时注意到的landscape-sysinfo

System load:  9.56              Processes:           135
  Usage of /:   80.7% of 7.69GB   Users logged in:     1
  Memory usage: 38%               IP address for eth0: xxx.xx.xx.xx
  Swap usage:   0%

这可能是问题所在吗？

答案1

我找到了一个解决方案，以防有人发现她，免责声明 ^^ 我无法解释为什么它停止工作以及为什么解决方案解决了这个问题。 gunicorn 日志中显示的错误似乎是一种默认问题，而真正的问题却没有出现。我怀疑这是一个 CPU 问题。

我只是去了 /venv/lib/python3.6/site-packages/gunicorn/config.conf 并添加了

threads = 2

它之前被设置为 1，现在将其设置为 2 就可以了。我非常乐意接受任何更好的修复，或者解释为什么它解决了这个问题。
