supervisord : supervisor的服务器端部分,启动supervisor就是运行这个命令


需求:./open_search 这个进程是运行go的一个服务。我们要求这个服务能在意外停止后自动重启。


yum install python-setuptools

easy_install supervisor

supervisord //启动supervisor

supervisorctl //打开命令行

[root@vm14211 ~]# supervisorctl

redis RUNNING pid 24068, uptime 3:41:55

ctl中: help //查看命令

ctl中: status //查看状态


如果修改了 /etc/supervisord.conf ,,需要执行 supervisorctl reload 来重新加载配置文件,否则会感觉没有生效,折腾到抓狂。。。
