Gunicorn 簡單使用
- 配置文件如下
import multiprocessing
bind = '0.0.0.0:8000'
workers = multiprocessing.cpu_count() * 2 + 1
# 服務連接已滿時，可容納的等待連接數，當超過該值時，服務會直接被拒絕
backlog = 2048
worker_class = "gevent"
# 最大連接數
worker_connections = 1000
threads = 30
# 後臺運行
daemon = True
proc_name = 'gunicorn_demo'
# 日誌輸出
access_log = "./logs/access_guni.log"
error_log = "./logs/error/guni.log"
# pid 用於啓停
pidfile = "./logs/guni.pid"
timeout = 600
- 服務啓停
- 啓動
gunicorn -c guni_config.py manage:app
- manage 就是 python 文件
mange.py
- 服務對象叫做 app
- 關閉
kill -9 ./logs/guni.pid
- 重啓
kill -HUP ./logs/guni.pid
- 配置 syslog(可輸出到 logstash)
syslog = True
syslog_addr = "udp://11.1.1.1:9090"
access_log_format = ''%(h)s %(l)s %(u)s %(t)s "%(r)s" %(s)s %(b)s "%(f)s" "%(a)s"''
