Nginx not running with no error message

I am trying to start my nginx server. When I type "$> /etc/init.d/nginx start", I have a message appearing "Starting nginx:", and then nothing happens. There is no error message, and when I check the status of nginx I see that it is not running.

Here is my /etc/nginx/nginx.conf file:

worker_processes  4;
daemon off;

error_log  /home/vincent/tmp/nginx.log;

pid        /home/vincent/tmp/nginx.pid;


events {
    worker_connections  1024;
}


http {
default_type  application/octet-stream;

log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for"';

access_log  /home/vincent/tmp/access.log  main;

sendfile        on;

keepalive_timeout  65;

include /etc/nginx/site-enabled/*;

}

And here is my /etc/nginx/sites-available/default file :

server {
  listen       80;
  server_name technical-test.neo9.lan; 

  access_log  /var/log/nginx/technical-test.neo9.lan.log main;

  set $home /home/vincent;

  location / {
    alias $home/neo9/web/app/;
    index  index.html;
  }

  location /api/ {
    rewrite  ^/api/(.*)$  /$1 break;
    proxy_pass http://localhost:1234;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
  }
}

First, always sudo nginx -t to verify your config files are good.

I ran into the same problem. The reason I had the issue was twofold. First, I had accidentally copied a log file into my site-enabled folder. I deleted the log file and made sure that all the files in sites-enabled were proper nginx site configs. I also noticed two of my virtual hosts were listening for the same domain. So I made sure that each of my virtual hosts had unique domain names.

sudo service nginx restart

Then it worked.

You should probably check for errors in /var/log/nginx/error.log.

In my case I did no add the port for ipv6. You should also do this (in case you are running nginx on a port other than 80): listen [::]:8000 default_server ipv6only=on;

In your /etc/nginx/nginx.conf file you have:

include /etc/nginx/site-enabled/*;

And probably the path you are using is:

/etc/nginx/sites-enabled/default

Notice the missing s in site.

One case you check that nginx hold on 80 number port in system by default , check if you have any server like as apache or anything exist on system that block 80 number port thats the problem occurred.

1 .You change port number on nginx by this way,

sudo vim /etc/nginx/sites-available/default

Change 80 to 81 or anything,

2. Check everything is ok by ,

sudo nginx -t

3. Restart server

sudo service nginx start

4. Check the status of nginx:

sudo service nginx status

Hope that will work

Check the daemon option in nginx.conf file. It has to be ON. Or you can simply rip out this line from config file. This option is fully described here http://nginx.org/en/docs/ngx_core_module.html#daemon
