Socket File not created when starting supervisor

[shad0wcrawl3r]

I recently faced an issue where once supervisor is started, the programs defined inside all start working but the socket file that is defined in the [unix_http_server].file is not created. When inspecting the directory where the socket file needs to be, the file was missing but the socket files for haproxy and nginx that I was testing supervisor with were present.

Edit: Supervisor Version being used is 4.2.1

[unix_http_server]
file = %(ENV_RUN_DIR)s/supervisor.sock

[supervisorctl]
serverurl = unix://%(ENV_RUN_DIR)s/supervisor.sock

root@ubuntu:/app/run# ls -l

I ran into a similar issue today,
check the solution proposed by @javabrett here: #376 (comment)

Adding that to my .conf resolved the issue for me.

It was so long without responses that I almost forgot about this. Apparently, it was due to an include directive that then overrode the configuration parameters.

This effectively caused the Unix Socket to be overridden and the socket from nginx_supervisor file being created in place of the prod/supervisor.
P.S.: The [inet_http_server] was used to control supervisor when the socket file was not being created as we had expected.
