当前supervisor配置：

[unix_http_server]
file=/tmp/supervisor.sock   ; (the path to the socket file)
chmod=0700                 ; socket file mode (default 0700)

;[inet_http_server]         ; inet (TCP) server disabled by default
;port=127.0.0.1:9001        ; (ip_address:port specifier,*:port for all iface)
;username=user              ; (default is no username (open server))
;password=123               ; (default is no password (open server))

[supervisord]
logfile=/opt/logs/supervisord.log ; (main log file;default $CWD/supervisord.log)
pidfile=/tmp/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
nodaemon=true               ; (start in foreground if true;default false)
minfds=1024                  ; (min. avail startup file descriptors;default 1024)
minprocs=200                 ; (min. avail process descriptors;default 200)

[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]
serverurl=unix:///tmp/supervisor.sock ; use a unix:// URL  for a unix socket
;serverurl=http://127.0.0.1:9001 ; use an http:// url to specify an inet socket


[include]
files = /etc/program.conf

正常情况下上面配置正常是能让supervisorctl加载当前supervisor管理的进程信息的，但是有时候换一个docker打包就不一定行，这个时候修改 supervisorctl 的链接方式从 serverurl=unix:///tmp/supervisor.sock，切换到serverurl=http://127.0.0.1:9001

具体配置如下：

[unix_http_server]
file=/tmp/supervisor.sock   ; (the path to the socket file)
chmod=0700                 ; socket file mode (default 0700)

[inet_http_server]         ; inet (TCP) server disabled by default
port=127.0.0.1:9001        ; (ip_address:port specifier,*:port for all iface)
;username=user              ; (default is no username (open server))
;password=123               ; (default is no password (open server))

[supervisord]
logfile=/opt/logs/supervisord.log ; (main log file;default $CWD/supervisord.log)
pidfile=/tmp/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
nodaemon=true               ; (start in foreground if true;default false)
minfds=1024                  ; (min. avail startup file descriptors;default 1024)
minprocs=200                 ; (min. avail process descriptors;default 200)

[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]
#serverurl=unix:///tmp/supervisor.sock ; use a unix:// URL  for a unix socket
serverurl=http://127.0.0.1:9001 ; use an http:// url to specify an inet socket
