good morning,
i new webserver infrastructures , administration. have following issue webserver try mount, using nginx + uwsgi + django , python: every refresh or request webpage user doing, uwsgi creates 2-3 new threads never terminate. after days, end more 30000 threads , have reload uwsgi in order maintain performance of webpage.
to check number of threads use following command: ps - elf | grep uwsgi (you can see result attached).
my uwsgi configuration following:
[uwsgi] vhost = true socket = /tmp/mysocket.sock master = true processes = 4 max_request = 300 vacuum = true die-on-term = true close-on-exec = true harakiri = 30 wsgi-file = /home/virtualenv/server/wsgi.py virtualenv = /home/virtualenv pythonpath = /home/virtualenv/myserver chdir=/home/virtualenv/myserver pidfile=/tmp/myfile.pid daemonize = /var/log/uwsgi/uwsgi-@(exec://date +%%y-%%m-%%d).log log-reopen = true chmod-socket = 664 gid = www-data uid = www-data my uwsgi.py file following:
import os import sys path = ‘/home/virtualenv/myserver' if path not in sys.path: sys.path.append(path) os.environ['django_settings_module'] = 'myserver.settings' django.core.wsgi import get_wsgi_application application = get_wsgi_application() and /etc/init/uwsgi.conf file is:
description "uwsgi emperor" start on runlevel [2345] stop on runlevel [!2345] respawn exec uwsgi --emperor /etc/uwsgi/vassals/ --wsgi-file /home/virtualenv/server/wsgi.py i have tried using uwsgi , without threads, , without --thunder-lock nothing changes.
edit:
after cleaning uwsgi.ini file continue having same issue. current configuration of files is:
uwsgi.ini:
[uwsgi] socket = /tmp/mysocket.sock master = true processes = 4 max_request = 3 vacuum = true die-on-term = true close-on-exec = true harakiri = 30 wsgi-file = /home/virtualenv/server/wsgi.py virtualenv = /home/virtualenv pythonpath = /home/virtualenv/myserver chdir=/home/virtualenv/myserver pidfile=/tmp/myfile.pid logger = file:/var/log/uwsgi/uwsgi-@(exec://date +%%y-%%m-%%d).log log-reopen = true chmod-socket = 664 gid = www-data uid = www-data uwsgi.conf
description "uwsgi emperor" start on runlevel [2345] stop on runlevel [!2345] respawn exec uwsgi --emperor /etc/uwsgi/vassals/ nginx.conf:

you're starting uwsgi emperor, shouldn't pass wsgi-file directly it. remove parameter uwsgi.conf file.
when using emperor, shouldn't daemonize uwsgi instances, because emperor loose connection it, causes spawning new instances on each request (emperor doesn't know there instances, because they've daemonized spawns new 1 handle requests). should remove daemonize uwsgi configuration.
also, using vhost when explicitly pointing wsgi file shouldn't done. if don't know parameter or don't think you're need it, remove it.
after changes, files should like:
uwsgi.ini file:
[uwsgi] socket = /tmp/mysocket.sock master = true processes = 4 max_request = 300 vacuum = true die-on-term = true close-on-exec = true harakiri = 30 wsgi-file = /home/virtualenv/server/wsgi.py virtualenv = /home/virtualenv pythonpath = /home/virtualenv/myserver chdir=/home/virtualenv/myserver pidfile=/tmp/myfile.pid log-reopen = true chmod-socket = 664 gid = www-data uid = www-data uwsgi.conf file:
description "uwsgi emperor" start on runlevel [2345] stop on runlevel [!2345] respawn exec uwsgi --emperor /etc/uwsgi/vassals/ wsgi.py file won't change.
if want have logfile uwsgi server, use:
logger = file:/var/log/uwsgi/uwsgi-@(exec://date +%%y-%%m-%%d).log instead of daemonize.
