How can I have same rule for two locations in NGINX config? (2023)

How can I have same rule for two locations in NGINX config?

I have tried the following

server { location /first/location/ | /second/location/ { .. .. }}

but nginx reload threw this error:

nginx: [emerg] invalid number of arguments in "location" directive**

How do I prevent a Gateway Timeout with FastCGI on Nginx

I am running Django, FastCGI, and Nginx. I am creating an api of sorts that where someone can send some data via XML which I will process and then return some status codes for each node that was sent over.

The problem is that Nginx will throw a 504 Gateway Time-out if I take too long to process the XML -- I think longer than 60 seconds.

So I would like to set up Nginx so that if any requests matching the location /api will not time out for 120 seconds. What setting will accomplish that.

What I have so far is:

 # Handles all api calls location ^~ /api/ { proxy_read_timeout 120; proxy_connect_timeout 120; fastcgi_pass 127.0.0.1:8080; }

Edit: What I have is not working :)

Nginx serves .php files as downloads, instead of executing them

I am installing a website in a droplet (Digital Ocean). I have an issue for install NGINX with PHP properly. I did a tutorial https://www.digitalocean.com/community/tutorials/how-to-install-linux-nginx-mysql-php-lemp-stack-on-ubuntu-14-04 but when I try to run some .php files it's just downloading it...for example... http://5.101.99.123/info.php it's working but... If I go to the main http://5.101.99.123 it's downloading my index.php :/

Any idea?

Other "locations" are commented on...

I need to serve my app through my app server at 8080, and my static files from a directory without touching the app server.

 # app server on port 8080 # nginx listens on port 8123 server { listen 8123; access_log off; location /static/ { # root /var/www/app/static/; alias /var/www/app/static/; autoindex off; } location / { proxy_pass http://127.0.0.1:8080; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } }

Now, with this config, everything is working fine. Note that the root directive is commented out.

If I activate root and deactivate the alias, it stops working. However, when I remove the trailing /static/ from root, it starts working again.

Can someone explain what's going on?

Nginx 403 forbidden for all files

I have nginx installed with PHP-FPM on a CentOS 5 box, but am struggling to get it to serve any of my files - whether PHP or not.

Nginx is running as www-data:www-data, and the default "Welcome to nginx on EPEL" site (owned by root:root with 644 permissions) loads fine.

The nginx configuration file has an include directive for /etc/nginx/sites-enabled/*.conf, and I have a configuration file example.com.conf, thus:

server { listen 80; Virtual Host Name server_name www.example.com example.com; location / { root /home/demo/sites/example.com/public_html; index index.php index.htm index.html; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_param SCRIPT_FILENAME /home/demo/sites/example.com/public_html$fastcgi_script_name; include fastcgi_params; }}

Despite public_html being owned by www-data:www-data with 2777 file permissions, this site fails to serve any content -

 [error] 4167#0: *4 open() "/home/demo/sites/example.com/public_html/index.html" failed (13: Permission denied), client: XX.XXX.XXX.XX, server: www.example.com, request: "GET /index.html HTTP/1.1", host: "www.example.com"

I've found numerous other posts with users getting 403s from nginx, but most that I have seen involve either more complex setups with Ruby/Passenger (which in the past I've actually succeeded with) or are only receiving errors when the upstream PHP-FPM is involved, so they seem to be of little help.

Have I done something silly here?

NGinx Default public www location?

I have Puma running as the upstream app server and Riak as my background db cluster. When I send a request that map-reduces a chunk of data for about 25K users and returns it from Riak to the app, I get an error in the Nginx log:

upstream timed out (110: Connection timed out) while reading response header from upstream

If I query my upstream directly without nginx proxy, with the same request, I get the required data.

The Nginx timeout occurs once the proxy is put in.

**nginx.conf**http { keepalive_timeout 10m; proxy_connect_timeout 600s; proxy_send_timeout 600s; proxy_read_timeout 600s; fastcgi_send_timeout 600s; fastcgi_read_timeout 600s; include /etc/nginx/sites-enabled/*.conf;}**virtual host conf**upstream ss_api { server 127.0.0.1:3000 max_fails=0 fail_timeout=600;}server { listen 81; server_name xxxxx.com; # change to match your URL location / { # match the name of upstream directive which is defined above proxy_pass http://ss_api; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_cache cloud; proxy_cache_valid 200 302 60m; proxy_cache_valid 404 1m; proxy_cache_bypass $http_authorization; proxy_cache_bypass http://ss_api/account/; add_header X-Cache-Status $upstream_cache_status; }}

Nginx has a bunch of timeout directives. I don't know if I'm missing something important. Any help would be highly appreciated....

nginx - client_max_body_size has no effect

nginx keeps saying client intended to send too large body. Googling and RTM pointed me to client_max_body_size. I set it to 200m in the nginx.conf as well as in the vhost conf, restarted Nginx a couple of times but I'm still getting the error message.

Did I overlook something? The backend is php-fpm (max_post_size and max_upload_file_size are set accordingly).

(13: Permission denied) while connecting to upstream:[nginx]

I am working with configuring Django project with Nginx and Gunicorn.

While I am accessing my port gunicorn mysite.wsgi:application --bind=127.0.0.1:8001 in Nginx server, I am getting the following error in my error log file;

How can I tell if my server is serving GZipped content?

I have a webapp on a NGinx server. I set gzip on in the conf file and now I'm trying to see if it works. YSlow says it's not, but 5 out of 6 websites that do the test say it is. How can I get a definite answer on this and why is there a difference in the results?

How to clear the cache of nginx?

I use nginx to as the front server, I have modified the CSS files, but nginx is still serving the old ones.

I have tried to restart nginx, to no success and I have Googled, but not found a valid way to clear it.

Some articles say we can just delete the cache directory: var/cache/nginx, but there is no such directory on my server.

What should I do now?

Have nginx access_log and error_log log to STDOUT and STDERR of master process

Is there a way to have the master process log to STDOUT STDERR instead of to a file?

It seems that you can only pass a filepath to the access_log directive:

access_log /var/log/nginx/access.log

And the same goes for error_log:

error_log /var/log/nginx/error.log

I understand that this simply may not be a feature of nginx, I'd be interested in a concise solution that uses tail, for example. It is preferable though that it comes from the master process though because I am running nginx in the foreground.

Node.js + Nginx - What now?

I've set up Node.js and Nginx on my server. Now I want to use it, but, before I start there are 2 questions:

How should they work together? How should I handle the requests?
There are 2 concepts for a Node.js server, which one is better:
a. Create a separate HTTP server for each website that needs it. Then load all JavaScript code at the start of the program, so the code is interpreted once.
b. Create one single Node.js server which handles all Node.js requests. This reads the requested files and evals their contents. So the files are interpreted on each request, but the server logic is much simpler.

It's not clear for me how to use Node.js correctly.

React-router and nginx

I am transitioning my react app from webpack-dev-server to nginx.

When I go to the root url "localhost:8080/login" I simply get a 404 and in my nginx log I see that it is trying to get:

my-nginx-container | 2017/05/12 21:07:01 [error] 6#6: *11 open() "/wwwroot/login" failed (2: No such file or directory), client: 172.20.0.1, server: , request: "GET /login HTTP/1.1", host: "localhost:8080"my-nginx-container | 172.20.0.1 - - [12/May/2017:21:07:01 +0000] "GET /login HTTP/1.1" 404 169 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:53.0) Gecko/20100101 Firefox/53.0" "-"

Where should I look for a fix ?

My router bit in react looks like this:

render( <Provider store={store}> <MuiThemeProvider> <BrowserRouter history={history}> <div> Hello there p <Route path="/login" component={Login} /> <App> <Route path="/albums" component={Albums}/> <Photos> <Route path="/photos" component={SearchPhotos}/> </Photos> <div></div> <Catalogs> <Route path="/catalogs/list" component={CatalogList}/> <Route path="/catalogs/new" component={NewCatalog}/> <Route path="/catalogs/:id/photos/" component={CatalogPhotos}/> <Route path="/catalogs/:id/photos/:photoId/card" component={PhotoCard}/> </Catalogs> </App> </div> </BrowserRouter> </MuiThemeProvider> </Provider>, app);

And my nginx file like this:

(Video) Nginx Reverse Proxy Set Up ( Multiple Server On The Same Port One IP )

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; server { listen 8080; root /wwwroot; location / { root /wwwroot; index index.html; try_files $uri $uri/ /wwwroot/index.html; } }}

EDIT:

I know that most of the setup works because when I go to localhost:8080 without being logged in I get the login page as well. this is not through a redirect to localhost:8080/login - it is some react code.

Nginx 403 error: directory index of [folder] is forbidden

I have 3 domain names and am trying to host all 3 sites on one server (a Digital Ocean droplet) using Nginx.

mysite1.namemysite2.namemysite3.name

Only 1 of them works. The other two result in 403 errors (in the same way).

In my nginx error log, I see: [error] 13108#0: *1 directory index of "/usr/share/nginx/mysite2.name/live/" is forbidden.

My sites-enabled config is:

server { server_name www.mysite2.name; return 301 $scheme://mysite2.name$request_uri;}server { server_name mysite2.name; root /usr/share/nginx/mysite2.name/live/; index index.html index.htm index.php; location / { try_files $uri $uri/ /index.html index.php; } location ~ \.php$ { fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; include fastcgi_params; }}

All 3 sites have nearly identical config files.

Each site's files are in folders like /usr/share/nginx/mysite1.name/someFolder, and then /usr/share/nginx/mysite1.name/live is a symlink to that. (Same for mysite2 and mysite3.)

I've looked at Nginx 403 forbidden for all files but that didn't help.

Any ideas on what might be wrong?

From inside of a Docker container, how do I connect to the localhost of the machine?

I have a Nginx running inside a docker container. I have a MySql running on the host system. I want to connect to the MySql from within my container. MySql is only binding to the localhost device.

Is there any way to connect to this MySql or any other program on localhost from within this docker container?

This question is different from "How to get the IP address of the docker host from inside a docker container" due to the fact that the IP address of the docker host could be the public IP or the private IP in the network which may or may not be reachable from within the docker container (I mean public IP if hosted at AWS or something). Even if you have the IP address of the docker host it does not mean you can connect to docker host from within the container given that IP address as your Docker network may be overlay, host, bridge, macvlan, none etc which restricts the reachability of that IP address.

Possible reason for NGINX 499 error codes
