Django被uWSGI启动时，不会将日志写入日志文件

Question

我是通过命令

python manage.py runserver

启动Django的。 Django 将日志写入文件

my_django_project/log/django.log

。 到目前为止一切顺利。

我是通过命令

uwsgi --ini uwsgi.ini

启动Django的。 我希望 Django 将日志写入文件

my_django_project/log/django.log

。 它创建了文件，但没有向其中写入任何内容。

我的 Django 项目有以下设置，名为

my_django_project

.

项目布局：

- my_django_project/
  - uwsgi.ini
  - manage.py
  - my_django_project/
    - __init__.py
    - settings.py
    - wsgi.py
  - log/
    - django.log

设置.py:

LOGGING = {
    "version": 1,
    "disable_existing_loggers": False,
    "formatters": {
        "verbose": {
            "format": "[{asctime}] [{name}] [{levelname}] [{filename}:{funcName}:{lineno}] {message}",
            'datefmt': "%Y-%m-%d %H:%M:%S",
            "style": "{",
        },
    },
    "handlers": {
        "console": {
            'level': 'DEBUG',
            "class": "logging.StreamHandler",
            "formatter": "verbose",
        },
        "django_file": {
            "level": "DEBUG",
            "class": 'logging.handlers.RotatingFileHandler',
            "formatter": "verbose",
            "filename": "log/django.log",
            'maxBytes': 10 * 1000 * 1000,  # 10 MB
            'backupCount': 3,
        },
    },
    "loggers": {
        "django": {
            "handlers": ["console", "django_file"],
            "level": "DEBUG",
        },
    },
}

wsgi.py:

import os

from django.core.wsgi import get_wsgi_application

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

application = get_wsgi_application()

uwsgi.ini:

# uwsgi.ini file

根据您提供的配置，您似乎已经在 Django 项目中正确设置了日志记录。然而，uWSGI 似乎没有获取 Django 日志记录配置。

为了在 uWSGI 中使用 Django 日志记录配置，您需要将以下行添加到您的 uwsgi.ini 文件中：

logger = file:log/django.log

这将告诉 uWSGI 使用 Django 日志记录配置中指定路径的文件记录器。

你的 uwsgi.ini 文件应该是这样的：

# uwsgi.ini file
[uwsgi]
module=my_django_project.wsgi
master=true
processes=1
http=:8000
vacuum=true
pidfile=/tmp/project-master.pid
logger=file:log/django.log
logto=./log/uwsgi.log
log-maxsize=10000000
enable-threads=true
thunder-lock=true

将此行添加到您的 uwsgi.ini 文件后，重新启动 uWSGI 并检查日志是否正在写入指定文件。
