autorestart=true
startsecs=5
startretries=3
stdout_logfile=/var/log/myservice_stdout.log
stderr_logfile=/var/log/myservice_stderr.log
environment=PYTHONUNBUFFERED=1

sudo supervisorctl reread                # 读取新配置
sudo supervisorctl update                # 更新配置
sudo supervisorctl start MyService       # 启动
sudo supervisorctl stop MyService        # 停止
sudo supervisorctl restart MyService     # 重启
sudo supervisorctl status                # 查看所有进程状态
sudo supervisorctl tail -f MyService     # 查看实时日志
