## Putting RQ under supervisor
|
|
|
|
[Supervisor][1] is a popular tool for managing long-running processes in
|
|
production environments. It can automatically restart any crashed processes,
|
|
and you gain a single dashboard for all of the running processes that make up
|
|
your product.
|
|
|
|
RQ can be used in combination with supervisor easily. You'd typically want to
|
|
use the following supervisor settings:
|
|
|
|
{% highlight ini %}
|
|
[program:myworker]
|
|
; Point the command to the specific rq command you want to run.
|
|
; If you use virtualenv, be sure to point it to
|
|
; /path/to/virtualenv/bin/rq
|
|
; Also, you probably want to include a settings module to configure this
|
|
; worker. For more info on that, see http://python-rq.org/docs/workers/
|
|
command=/path/to/rq worker -c mysettings high default low
|
|
; process_num is required if you specify >1 numprocs
|
|
process_name=%(program_name)s-%(process_num)s
|
|
|
|
; If you want to run more than one worker instance, increase this
|
|
numprocs=1
|
|
|
|
; This is the directory from which RQ is ran. Be sure to point this to the
|
|
; directory where your source code is importable from
|
|
directory=/path/to
|
|
|
|
; RQ requires the TERM signal to perform a warm shutdown. If RQ does not die
|
|
; within 10 seconds, supervisor will forcefully kill it
|
|
stopsignal=TERM
|
|
|
|
; These are up to you
|
|
autostart=true
|
|
autorestart=true
|
|
{% endhighlight %}
|
|
|
|
### Conda environments
|
|
|
|
[Conda][2] virtualenvs can be used for RQ jobs which require non-Python
|
|
dependencies. You can use a similar approach as with regular virtualenvs.
|
|
|
|
{% highlight ini %}
|
|
[program:myworker]
|
|
; Point the command to the specific rq command you want to run.
|
|
; For conda virtual environments, install RQ into your env.
|
|
; Also, you probably want to include a settings module to configure this
|
|
; worker. For more info on that, see http://python-rq.org/docs/workers/
|
|
environment=PATH='/opt/conda/envs/myenv/bin'
|
|
command=/opt/conda/envs/myenv/bin/rq worker -c mysettings high default low
|
|
; process_num is required if you specify >1 numprocs
|
|
process_name=%(program_name)s-%(process_num)s
|
|
|
|
; If you want to run more than one worker instance, increase this
|
|
numprocs=1
|
|
|
|
; This is the directory from which RQ is ran. Be sure to point this to the
|
|
; directory where your source code is importable from
|
|
directory=/path/to
|
|
|
|
; RQ requires the TERM signal to perform a warm shutdown. If RQ does not die
|
|
; within 10 seconds, supervisor will forcefully kill it
|
|
stopsignal=TERM
|
|
|
|
; These are up to you
|
|
autostart=true
|
|
autorestart=true
|
