How can I have Supervisor running my programs as another user?

  • 772

I'm having a lot of trouble making supervisor running my commands with expanded environment variables.

My supervisor conf.

; 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)
user = a-user-name
environment = HOME='/home/a-user-name',APP='staging.example.com',SYMFONY_ENVIRONMENT='staging'

; 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.

[include]
files = /etc/supervisor/conf.d/*.conf
files = /home/a-user-name/apps/staging.example.com/current/app/Resources/config/supervisor/*.conf

And under-version-control.conf in ~/apps/staging.example.com/current/app/Resources/config/supervisor

[program:hank-message-forwarder]
stdout_logfile = /var/log/pink-tie/%(program_name)s-out.log
stderr_logfile = /var/log/pink-tie/%(program_name)s-err.log
logfile_maxbytes = 50MB
logfile_backups = 10
identifier = hank-message-forwarder
command = %(ENV_HOME)s/apps/%(ENV_APP)s/current/bin/hank forward-messages tcp://*:5500 tcp://*:5600

What am I doing wrong here? The error I'm getting is not helpful at all. It's complaining about the fact that it can't connect to the unix server but once I remove the files, user and environment directive (all that I've changed basically) all goes back to normal.

  1. but once I remove the files, user and environment directive (all that I've changed basically) all goes back to normal.

    Sounds like you have a syntax problem. After referencing the online documentation... The user entry looks good. user = a-user-name But the environment looks odd to me. Try changing your single-quotes to double-quotes.

    Change it from this;

    environment = HOME='/home/a-user-name',APP='staging.example.com',SYMFONY_ENVIRONMENT='staging'

    To this;

    environment = HOME="/home/a-user-name",APP="staging.example.com",SYMFONY_ENVIRONMENT="staging"

    EDIT:

    I just noticed you have an asteriks in one of your "files=" lines. This I haven't seen before in practice (I've only specified complete filenames). But the online documentation does show wildcards ("*" and "?").

    However, the Online documentation mentions the following (emphasis added);

    If the configuration file contains an [include] section, it must contain a single key named “files”. The values in this key specify other configuration files to be included within the configuration.

  2. Without actually looking in detail. One thought came to mind. You can't run a process as another user unless that user has sufficient privileges to do so.

    So the question is to you, is supervisord running as root or as a lower privilege user?
