1. yum install supervisor
2. vim /etc/supervisord.conf
chose unix_http_server or inet_http_server
[unix_http_server]
file=/var/run/supervisor/supervisor.sock ; (the path to the socket file)
;chmod=0700 ; sockef file mode (default 0700)
;chown=nobody:nogroup ; socket file uid:gid owner
;username=user ; (default is no username (open server))
;password=123 ; (default is no password (open server))
可以使用浏览器查看和控制进程状态 http://172.16.5.20:9001 登录
[inet_http_server] ; inet (TCP) server disabled by default
port=172.16.5.20:9001 ; (ip_address:port specifier, *:port for all iface)
username=user ; (default is no username (open server))
password=123 ; (default is no password (open server))

4. supervisord -c /etc/supervisord.conf
5. supervisorctl reload 重新加载配置文件
supervisorctl update
supervisorctl shutdown
supervisorctl status
6. supervisorctl 命令行
> help status
# supervisorctl
fluentd2kafka RUNNING pid 8094, uptime 0:12:10
supervisor>
# supervisorctl status
fluentd2kafka RUNNING pid 8094, uptime 0:12:28
7. supervisorctl start fluentd2kafka #启动这里改为start
supervisorctl stop fluentd2kafka # 停止
8. ps -ef | grep super
