nginx location 404 not found

Question

Here are my nginx configure files.

On the default.conf, the first location is used to access /usr/share/nginx/html directory, it is ok while I access http://47.91.152.99. But when I add up a new location for directory /usr/share/nginx/public directory, nginx return me a 404 page while I access http://47.91.152.99/test.

So, what is the matter? Am I misuse the directive of nginx?

/etc/nginx/nginx.conf

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    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  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}


/etc/nginx/conf.d/default.conf
server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    location ^~ /test/ {
        root /usr/share/nginx/public;
        index index.html index.htm;
    }
    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

Answer 1

The following erroneous block (in your case);

 location ^~ /test/ {
     root /usr/share/nginx/public;
     index index.html index.htm;
 }

is telling nginx to look for directory 'test' into the folder (root) /usr/share/nginx/public. If there's no 'test' folder in that root, it will return 404. To paliate to your problem, i suggest you try using alias instead of root. Like so:

 location ^~ /test/ {
     alias /usr/share/nginx/public;
     index index.html index.htm;
 }

Also, just for kicks, index directive can be set generally so you don't have to re-write it all the time... like so;

 server {
     listen       80;
     server_name  localhost;

     root   /usr/share/nginx/html;
     index  index.html index.htm;

     error_page   500 502 503 504  /50x.html;

     location / { }

     location ~^/test/ {
         alias /usr/share/nginx/public;
     }

     location = /50x.html {
         root   /usr/share/nginx/html;
     }
 }

One thing you should also consider... the more 'precise' the location block, the higher in your config it should reside. Like that location = /50x.html. In a perfect world, that would be set up top, right after the general server block settings.

Hope it helps.

Error caused by root directive

location ^~ /test/ {
    root /usr/share/nginx/public;
    index index.html index.htm;
}

Fix with alias directive

 location ^~ /test/ {
     alias /usr/share/nginx/public;
     index index.html index.htm;
 }

Other Improvements

Extra tip: the index directive can be set so that you don't have to re-write it.

server {
    listen       80;
    server_name  localhost;

    root   /usr/share/nginx/html;
    index  index.html index.htm;

    error_page   500 502 503 504  /50x.html;

    location / { }

    location ~^/test/ {
        alias /usr/share/nginx/public;
    }

    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

nginx matches Location blocks partly based on position in the config. Ideally, you would invert what you have now. The location block would be higher in nginx config. To that end, the location = /50x.html would also move up. Order is

1. Exact match =
2. Forward match ^~ /
3. Case sensitive regex ~ /
4. Case insensitive regex ~*
5. Path match /

More about nginx location priority. Also, you can always review the official documentation. The nginx documentation for location block http://nginx.org/en/docs/http/ngx_http_core_module.html#location

when your app is vuejs，you need write like this,can prevent 404,pay attention to double /test/

   location ^~/test/ {
       alias /usr/local/soft/vuejs/;
       try_files $uri $uri/ /test/index.html;
    }

I just solved this (index.html not found) issue.
For me, I misstyped my project name to match your ec2 project name with the nginx path.

Move to nginx/sites-enabled to check nginx path

1. cd /etc/nginx/sites-enabled
2. cat your_project_name
3. Check your nginx path (for me : root/home/ubuntu/practice/current/public;)
   

Move to home directory to check your project name
4. cd
5. ls
6. If your ec2 project name(for me: practice) is not match with your nginx path name(for me: practice) then you might got "index.html not found error"

and my server-blocks.conf

server {

        listen 80;

        index index.html index.htm index.nginx-debian.html;

        server_name 13.xxx.xxx.xx;

        location / {
        root /var/www/portaladmin/;


                proxy_pass http://13.xxx.xxx.xx:80/;

        }
         error_log /var/log/nginx/portaladmin-erorr.log;

}

and my load-balancer.conf

server {
  listen 80;
  server_name xx.xxx.xxx.xx
  access_log /home/ec2-user/logs/lb-access.log;
  error_log /home/ec2-user/logs/lb-error.log;

  location / {
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://13.xxx.xxx.xx:80;
           }
}

Creating nginx & sftp pods using Kubernetes.. I've found that the mountPath in my sftp-deployment.yaml file is related to the username in my sftp-server.

And the error has happened when I have changed the username without changing mountPath value to match my username. So, the files were uploading to '/home/old-username' instead of '/home/new-username'.
