How can I run uWsgi as a service in CentOs?

Question

I am in a hurry, I can find out how to do this but I need some help to achieve this without loosing too much time. Currently what I do to run a uWsgi instance along with my ini file is just:

uwsgi --ini /home/myonlinesite/uwsgi.ini --pidfile /var/run/uwsgi_serv.pid

and then to stop:

uwsgi --stop  /var/run/uwsgi_serv.pid.

By the way, I have this code inside a uwsgi init file in my /etc/init.d/uwsgi. so when I run /etc/init.d/uwsgi start it executes the ini config file and when I execute /etc/init.d/uwsgi stop it stops the uwsgi process id.

The problem is that when I start the uWsgi service it runs normally and logs every http request, any debug print and so on, but when I close putty which is where I run my Vps it kills all uWsgi process and quits the site from being displayed.

I do not know if I have to touch the pid file only, or what do I need to do leave the uWsgi process executing and I can close putty.

Thanks in advance.

Answer 1

If you are setting the parameters in the command line, add the flag -d file.log to your command (-d stands for daemonize):

uwsgi --ini /home/myonlinesite/uwsgi.ini --pidfile /var/run/uwsgi_serv.pid -d file.log

If you are setting the parameters in a config file, add the following line in your config:

daemonize = /absolute/path/to/file.log

In both cases, uWsgi will run in the background and log everything in file.log. Given these options, there is no need using nohup et al.

Answer 2

Be sure to add

daemon = logfile

to your config

Answer 3

Using nohup to start the uWsgi process should solve your problem of the process stopping when you log out.
