; 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=/var/run/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=0.0.0.0:9001 ; ip_address:port specifier, *:port for all iface
; username=hadoop ; default is no username (open server)

; added by defining them in separate [rpcinterface:x] sections.

supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
