Supervisor管理
#
在linux服务器上部署了node项目，使用supervisor进行管理
要使更新的配置得以应用，需要重新启动supervisor服务。具体操作如下：
二、更新新的配置到supervisord
配置文件： /etc/supervisord.conf
supervisorctl update
三、重新启动配置中的所有程序
supervisorctl reload
四、启动某个进程(program_name=你配置中写的程序名称)
supervisorctl start program_name
五、查看正在守候的进程
supervisorctl
六、停止某一进程 (program_name=你配置中写的程序名称)
supervisorctl stop program_name
七、重启某一进程 (program_name=你配置中写的程序名称)
supervisorctl restart program_name
