I use supervisor to run Nginx and Gunicorn side by side on a Docker container.

This was the configuration used for supervisor :

[supervisord]
nodaemon=true

[program:gunicorn]
command = /project/start.sh
user = www-data


[program:nginx]
command=/usr/sbin/nginx

The problem was how I launched Ngnix : by default it runs on the foreground. This makes supervise retry to run another instance of Nginx.

By adding -g 'daemon off;' to the command line, Nginx stayed in the foreground, supervisor stopped trying to run another instance.

First change apache listen port 80 to 8080 apache in  etc apache2 ports conf include  Listen 1 2 3 4 80 to 1 2 3 4 8080 sudo service apache2 restart    or   sudo service httpd restart       in case of centos   then add nginx as reverse proxy server that will listen apache port  server    listen   1 2 3 4 80   server name  some com    access log   var log nginx something-access log    location       proxy pass http   localhost 8080    proxy redirect off    proxy set header Host  host    proxy set header X-Real-IP  remote addr    proxy set header X-Forwarded-For  proxy add x forwarded for       location          jpg js jpeg png        root  usr share nginx html      location  404 html     root  usr share nginx html 40x html     error page 404  404 html      location    40x html      error page 500 502 503 504  50x html      location    50x html        put code for static content like js css images fonts     After changes restart nginx server  sudo service nginx restart   Now all traffic will be handled by nginx server and send all dynamic request to apache and static conten is served by nginx server   For advance configuration like cache    https   www linode com docs web-servers nginx slightly-more-advanced-configurations-for-nginx  basic-nginx-caching

In my case the culprit turned out to be a server-block that contained           listen  127 0 0 1 80          listen     1  80 ipv6only on          server name  localhost    On Linux  a socket listening on a specific IP  e g     1  80  conflicts with a socket listening on the same port but any IP  i e       80   Normally nginx will transparently deal with this problem by using a single socket behind this scenes  However  explicitly specifying ipv6only  or certain other options  on the listen directive forces nginx to  try to  create a separate socket for it  thus resulting in the Address already in use error   Since ipv6only on is the default anyway  since 1 3 4  the fix was simply to remove that option from this directive  and making sure ipv6only wasn t used anywhere else in my config

User · Answer

80 is a ipv6 address   This error can be caused if you have a nginx configuration that is listening on port 80 and also on port      80   I had the following in my default sites-available file   listen 80  listen      80 default server    You can fix this by adding ipv6only on to the      80 like this   listen 80  listen      80 ipv6only on default server    For more information  see   http   forum linode com viewtopic php t 8580  http   wiki nginx org HttpCoreModule listen
