我将从我的用例开始,因为我很可能没有使用正确的工具来完成这项工作.如果我以错误的方式解决这个问题,请告诉我
原文链接：https://www.f2er.com/centos/373599.html用例：我有一个托管多个网络应用的CentOS服务器.我希望能够相信我的Web服务器和应用程序服务器将会运行.我的堆栈看起来像
> web服务器：Nginx
>应用服务器：uWSGI
> web框架：flask / python
我想使用supervisord来监控Nginx和uWSGI.在我的/etc/supervisor.conf中,我有
[program:Nginxgo] command = /usr/sbin/Nginx autostart=true autorestart=unexpected exitcodes=0 stdout_logfile=/home/webdev/Nginxgo.log stderr_logfile=/home/webdev/Nginxgoerr.log [program:uwsgi_emperor_go] command = uwsgi --emperor /etc/uwsgi/emperor.ini autostart=true autorestart=unexpected stopsignal=INT stdout_logfile=/home/webdev/emp.log stderr_logfile=/home/webdev/emperr.log directory=/home/webdev/ user=webdev
我启动了uWSGI流程.当我输入[root @ mymachine]#/usr/local / bin / supervisord -n -c /etc/supervisord.conf时
输出是

看看它是怎么说的
2014-11-26 14:07:59,process has stayed up for > than 1 seconds (startsecs)
但它开始只是循环Nginxgo过程.我用CTRL-C杀死了supervisord实例,我在htop中看到Nginx主进程和工作进程都是活动的.
我想要的是在服务器启动/重启或任一程序失败时启动Nginx和我的uWSGI emperor
