问题：安装了supervisor3.2.0，在python3环境下启动会报错：

pkg_resources.DistributionNotFound: The 'supervisor==3.2.0' distribution was not found and is required by the application

解决方式：

# pip install virtualenv
# virtualenv --distribute -p /usr/bin/python2 supervisor
Running virtualenv with interpreter /usr/bin/python2
Already using interpreter /usr/bin/python2
New python executable in /home/yu/super/bin/python2
Also creating executable in /home/yu/super/bin/python
Installing setuptools, pip, wheel...
done.
# ls supervisor
bin  lib  local
# cd supervisor
# source  bin/activate
# ./bin/pip install supervisor
# supervisord -c /etc/supervisor/supervisord.conf
//退出virtulenv
# deactivate

supervisord.conf示例：

; supervisor config file

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

[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

; 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.

[inet_http_server]
port=*:19000
username=super
password=1234567

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