gunicorn 配置示例说明

gunicorn_config_demo.py

import multiprocessing

# example:
# gunicorn app:app -b localhost:10021 -w 3 -D -k uvicorn.workers.UvicornWorker --error-logfile ./logs/gunicorn_error.log --log-level warning

# 并行工作进程数
workers = multiprocessing.cpu_count()*2+1  # -w 3

# 监听内网端口
bind = '0.0.0.0:8000'  # -b 0.0.0.0:8000

# 设置守护进程
daemon = True  # -D

# 工作模式协程
worker_class = 'uvicorn.workers.UvicornWorker'  # -k uvicorn.workers.UvicornWorker

# 记录 gunicorn 主进程 id 到文件
# 可通过操作此文件重启、关机 gunicorn
# 重启：kill -HUP ./pid.pid
# 关机：kill -TERM ./pid.pid
pidfile = './pid.pid'

# 启动异常日志记录，及级别
errorlog = './logs/gunicorn_error.log'  # --error-logfile ./logs/gunicorn_error.log
loglevel = 'warning'  # --log-level warning
