directory = /root/server/server/
command = gunicorn --pythonpath /root/server/venv/bin/python3 -w 3 -b 0.0.0.0:80 server.wsgi

redirect_stderr = true
stdout_logfile_maxbytes = 10MB
stdout_logfile_backups = 1
stdout_logfile = /root/logs/server.log

启动

supervisord -c /etc/supervisor/supervisor.conf

常用指令

root@tianshl:~# supervisorctl -c /etc/supervisor/supervisor.conf reload         # 重新加载配置文件
root@tianshl:~# supervisorctl -c /etc/supervisor/supervisor.conf status         # 服务状态
root@tianshl:~# supervisorctl -c /etc/supervisor/supervisor.conf start server   # 启动某个服务(这里的server是服务名称，即program的名字)
root@tianshl:~# supervisorctl -c /etc/supervisor/supervisor.conf restart server # 重启某个服务
root@tianshl:~# supervisorctl -c /etc/supervisor/supervisor.conf stop server    # 停止某个服务
