-# netdata via nginx
-
-To pass netdata via a nginx, use this:
-
-### As a virtual host
-
-```
-upstream backend {
-    # the netdata server
-    server 127.0.0.1:19999;
-    keepalive 64;
-}
-
-server {
-    # nginx listens to this
-    listen 80;
-
-    # the virtual host name of this
-    server_name netdata.example.com;
-
-    location / {
-        proxy_set_header X-Forwarded-Host $host;
-        proxy_set_header X-Forwarded-Server $host;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_pass http://backend;
-        proxy_http_version 1.1;
-        proxy_pass_request_headers on;
-        proxy_set_header Connection "keep-alive";
-        proxy_store off;
-    }
-}
-```
-
-### As a subfolder to an existing virtual host
-
-```
-upstream netdata {
-    server 127.0.0.1:19999;
-    keepalive 64;
-}
-
-server {
-   listen 80;
-
-   # the virtual host name of this subfolder should be exposed
-   #server_name netdata.example.com;
-
-   location = /netdata {
-        return 301 /netdata/;
-   }
-
-   location ~ /netdata/(?<ndpath>.*) {
-        proxy_redirect off;
-        proxy_set_header Host $host;
-
-        proxy_set_header X-Forwarded-Host $host;
-        proxy_set_header X-Forwarded-Server $host;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_http_version 1.1;
-        proxy_pass_request_headers on;
-        proxy_set_header Connection "keep-alive";
-        proxy_store off;
-        proxy_pass http://netdata/$ndpath$is_args$args;
-
-        gzip on;
-        gzip_proxied any;
-        gzip_types *;
-    }
-}
-```
-
-### As a subfolder for multiple netdata servers, via one nginx
-
-```
-upstream backend-server1 {
-    server 10.1.1.103:19999;
-    keepalive 64;
-}
-upstream backend-server2 {
-    server 10.1.1.104:19999;
-    keepalive 64;
-}
-
-server {
-    listen 80;
-
-    # the virtual host name of this subfolder should be exposed
-    #server_name netdata.example.com;
-
-    location ~ /netdata/(?<behost>.*)/(?<ndpath>.*) {
-        proxy_set_header X-Forwarded-Host $host;
-        proxy_set_header X-Forwarded-Server $host;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_http_version 1.1;
-        proxy_pass_request_headers on;
-        proxy_set_header Connection "keep-alive";
-        proxy_store off;
-        proxy_pass http://backend-$behost/$ndpath$is_args$args;
-
-        gzip on;
-        gzip_proxied any;
-        gzip_types *;
-    }
-
-    # make sure there is a trailing slash at the browser
-    # or the URLs will be wrong
-    location ~ /netdata/(?<behost>.*) {
-        return 301 /netdata/$behost/;
-    }
-}
-```
-
-Of course you can add as many backend servers as you like.
-
-Using the above, you access netdata on the backend servers, like this:
-
-- `http://nginx.server/netdata/server1/` to reach `backend-server1`
-- `http://nginx.server/netdata/server2/` to reach `backend-server2`
-
-
-### Enable authentication
-
-Create an authentication file to enable the nginx basic authentication.
-Do not use authentication without SSL/TLS!
-If you haven't one you can do the following:
-
-```
-printf "yourusername:$(openssl passwd -apr1)" > /etc/nginx/passwords
-```
-
-And enable the authentication inside your server directive:
-
-```
-server {
-    # ...
-    auth_basic "Protected";
-    auth_basic_user_file passwords;
-    # ...
-}
-```
-
-## limit direct access to netdata
-
-If your nginx is on `localhost`, you can use this to protect your netdata:
-
-```
-[web]
-    bind to = 127.0.0.1 ::1
-```
-
----
-
-You can also use a unix domain socket. This will also provide a faster route between nginx and netdata:
-
-```
-[web]
-    bind to = unix:/tmp/netdata.sock
-```
-_note: netdata v1.8+ support unix domain sockets_
-
-At the nginx side, use something like this to use the same unix domain socket:
-
-```
-upstream backend {
-    server unix:/tmp/netdata.sock;
-    keepalive 64;
-}
-```
-
----
-
-If your nginx server is not on localhost, you can set:
-
-```
-[web]
-    bind to = *
-    allow connections from = IP_OF_NGINX_SERVER
-```
-
-_note: netdata v1.9+ support `allow connections from`_
-
-`allow connections from` accepts [netdata simple patterns](../libnetdata/simple_pattern/) to match against the connection IP address.
-
-## prevent the double access.log
-
-nginx logs accesses and netdata logs them too. You can prevent netdata from generating its access log, by setting this in `/etc/netdata/netdata.conf`:
-
-```
-[global]
-      access log = none
-```
-
-## SELinux
-
-If you get an 502 Bad Gateway error you might check your nginx error log:
-
-```sh
-# cat /var/log/nginx/error.log:
-2016/09/09 12:34:05 [crit] 5731#5731: *1 connect() to 127.0.0.1:19999 failed (13: Permission denied) while connecting to upstream, client: 1.2.3.4, server: netdata.example.com, request: "GET / HTTP/2.0", upstream: "http://127.0.0.1:19999/", host: "netdata.example.com"
-```
-
-If you see something like the above, chances are high that SELinux prevents nginx from connecting to the backend server. To fix that, just use this policy: `setsebool -P httpd_can_network_connect true`.
