supervisor

; Sample supervisor config file.
;
; For more information on the config file, please see:
; http://supervisord.org/configuration.html
;
; Notes:
;  - Shell expansion ("~" or "$HOME") is not supported.  Environment
;    variables can be expanded using this syntax: "%(ENV_HOME)s".
;  - Quotes around values are not supported, except in the case of
;    the environment= options as shown below.
;  - Comments must have a leading space: "a=b ;comment" not "a=b;comment".
;  - Command will be truncated if it looks like a config file comment, e.g.
;    "command=bash -c 'foo ; bar'" will truncate to "command=bash -c 'foo ".
;
; Warning:
;  Paths throughout this example file use /tmp because it is available on most
;  systems.  You will likely need to change these to locations more appropriate
;  for your system.  Some systems periodically delete older files in /tmp.
;  Notably, if the socket file defined in the [unix_http_server] section below
;  is deleted, supervisorctl will be unable to connect to supervisord.

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

; Security Warning:
;  The inet HTTP server is not enabled by default.  The inet HTTP server is
;  enabled by uncommenting the [inet_http_server] section below.  The inet
;  HTTP server is intended for use within a trusted environment only.  It
;  should only be bound to localhost or only accessible from within an
;  isolated, trusted network.  The inet HTTP server does not support any
;  form of encryption.  The inet HTTP server does not use authentication
;  by default (see the username= and password= options to add authentication).
;  Never expose the inet HTTP server to the public internet.

[inet_http_server]         ; inet (TCP) server disabled by default
port=*:9001        ; ip_address:port specifier, *:port for all iface
