supervisord – supervisorctl不会停止正在运行的进程

我无法让主管正确地拖尾运行流程.我正在运行3.0a8版本.

这是我的supervisord.conf文件

[inet_http_server]
port=9011

[supervisord]
logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log)
pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
childlogdir=/var/log/supervisor            ; ('AUTO' child log dir,default $TEMP)

; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work,additional interfaces may be
; added by defining them in separate rpcinterface: sections
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]
;serverurl=unix:///var/run//supervisor.sock ; use a unix:// URL  for a unix socket
serverurl=http://localhost:9011


; The [include] section can just contain the "files" setting.  This
; setting can list multiple files (separated by whitespace or
; newlines).  It can also contain wildcards.  The filenames are
; interpreted as relative to this file.  Included files *cannot*
; include files themselves.

[include]
files = /etc/supervisor/conf.d/*.conf

这是最基本的超级用户配置文件,保存在/etc/supervisord/conf.d/duder.conf中

[program: duder]
command=/bin/cat

但是,这是我与主管的终端会话的样子

vagrant@lucid64:/etc/supervisor/conf.d$sudo supervisorctl 
 duder                           RUNNING    pid 31795,uptime 0:03:32
 supervisor> tail duder
 duder: ERROR (no such process name)

有任何想法吗？
