nginx(ng1): 172.168.240.5
Gitlab includ nginx (ng2): 172.168.240.55
ng1 config
listen 81;
server_name ng1;
location /gitlab/ {
proxy_pass 172.168.240.55/
}
how can I keep port and url without updating ng2. // only modify ng1
url gitlab lost
it's login(POST) http://ng1:81/gitlab/users/sign_in
but it's show http://ng1:81/users/sign_in instead of http://ng1:81/gitlab/users/sign_in
it seems to be rewrite by ng2
url gitlab and port lost
click one file in http://ng1:81/gitlab/root/pg/
but it's http://ng1/root/pg/index.html instead of http://ng1:81/gitlab/root/pg/index.html
need nginx reverse proxy
/servername/port/ for dynamic servername and port
I find resolve (dns server + nginx)
Using nginx regex location matching to dynamically map URI's to different ports for multiple reverse proxies

I have a Jenkins environment setup, running off a EC2 instance and trying to get port 80 mapped to port 8080.
A suggestion made (and the way most of the configurations I've seen recommended) uses Nginx to do a reverse proxy.
I have installed Nginx on the server, and added to sites-available the following:
server {
listen 80;
server_name jenkins.acue.io;
location / {
include /etc/nginx/proxy_params;
proxy_pass http://localhost:8080;
proxy_read_timeout 60s;
# Fix the "It appears that your reverse proxy set up is broken" error.
# Make sure the domain name is correct
proxy_redirect http://localhost:8080 https://jenkins.acue.io;
}
}
I hit the IP address of the jenkins environment, it shows me the Ngnix welcome screen and Jenkins still loads against port 8080 not port 80.
Do I need to specific the current URL (I've not pointed the jenkins.acue.io sub-domain yet to the EC2 instance where I have specified localhost? I've tried it but no joy).
Few things to note.
You need to add jenkins.acue.io to your Host entries and point it to the instance where you are running NginX. Then use the FQDN to access Jenkins. Also there is a typo in your proxy_redirect where you have added https URL instead of http://jenkins.acue.io fix that as well. Other than that your NginX configurations look fine.
If you keep on getting the NginX welcome page even though you are accessing through the FQDN, that means your configurations are not being picked up by NginX. Try creating a new file like jenkins.conf and add it to /etc/nginx/conf.d. Then do a sudo systemctl restart nginx
I can rewrite some specific http folders to https folders, but i can't rewrite all https except these specific folders from https to http; i'm stuck in a loop
Using NGinx 1.12 as a proxy, handling both http and https
i have one server section to handle http 80 and one server section to handle https (i know they can be together in the same section).
both of them are beginning that way
location / {
proxy_pass
server {
listen 80;
i have
location ~ ^/(xxx|yyy|zzz)/.*$ {
rewrite ^ https://www.example.com$uri permanent;
}
and anytime i'm in http, it is redirecting to https fine for the xxx,yyy and zzz folders. so far, so good.
but under server {
listen 443 ssl;
, i would like to redirect everything except the xxx,yyy,zzz folder to go back to http.
I did try to do the reverse in the https section meaning :
location / {
rewrite ^ http://www.example.com$uri permanent;
}
and
location ~ ^/(xxx|yyy|zzz)/.*$ {
#do nothing
}
but it is not working, either i get a 404 error or a loop
The only solution i found as Nginx is a proxy is making Apache handling the redirect on its side.
so,
a. nginx 80 is redirecting to nginx 443 specific folders.
b. all https is redirect by nginx 443 to apache 443, and then in apache 443 conf i do a test, if it the specific folders, i stop, and otherwise i redirect to nginx 80.
It's working, but i'm sure it is possible to make nginx handle it and avoid this 1 loop. if someone as a beautiful answer :-)
Is it possible to set up nginx to reverse proxy server.com/[port]/rest/of/url to server.com:[port]/rest/of/url ?
For example,
server.com/12345/files should proxy server.com:12345/files. The ports are random and there could 100s of such ports.
I have docker containers in a linux VM which bind to random ports on the host and serve HTTP. I'm trying to setup a proxy for them on a single port.
Something like this should do the trick:
server {
listen 80;
location ~ ^/(?<port>\d+)/ {
rewrite ^/\d+(/.*) $1 break;
proxy_pass http://127.0.0.1:$port;
}
}

I'm a noob in nginx. I start configuring my domains (marianamarques.ntr.br and fabricadevozes.com.br) dns to point to my aws ec2 instance public ip. Thats ok.
When i start configure the nginx:
i created /var/www
i created /var/www/marianamarques.ntr.br/public_html
i created /var/www/fabricadevozes.com.br/public_html
i created /etc/nginx/sites-availble/marianamarques.ntr.br.conf listening to port 80 with root pointing to /var/www/marianamarques.ntr.br/public_html
i created /etc/nginx/sites-availble/fabricadevozes.com.br.conf listening to port 80 with root pointing to /var/www/fabricadevozes.com.br/public_html
When i tell on browser http://www.fabricadevozes.com.br i got htmls from /var/www/fabricadevozes.com.br/public_html but when i tell on browser http://www.marianamarques.ntr.br i got htmls from /var/www/fabricadevozes.com.br/public_html too.
I'm a bit desperated. My nginx was installed from apt-get and after hours and hours of web searches i know my /etc/nginx/conf.d/nginx.conf was missing (i don't have this file) but my nginx server starts with no issues.
Anybody can help?
nginx.conf should be located in /etc/nginx.
Post it along with your config files in sites-enabled and it'll be easier to tell you exactly what's wrong, but sounds like you may have a mistake in the server_name or root directives in your server definition. Make sure you specify the server name with and without the www. It could be loading your default domain if you didn't specify www. in the server name
server {
listen 80;
server_name marianamarques.ntr.br www.marianamarques.ntr.br;
root /var/www/marianamarques.ntr.br/public_html;
...
}
If thats not it, we'd need to see the config files.
Solved based on the link Nginx no-www to www and www to no-www - i create a second server listening to same port but expecting the server_name with-www prefix and then rewrite this to my other server point to without-www prefix like this:
server {
server_name www.domain.com;
rewrite ^(.*) http://domain.com$1 permanent;
}
server {
server_name domain.com;
#The rest of your configuration goes here#
}
I expect it can help others. Thanks a lot for everything! And sorry... my english is very poor!
Apparently you solved the problem but let me explain why it happened, you should read How nginx processes a request
Quote:
In this configuration nginx tests only the request’s header field
“Host” to determine which server the request should be routed to. If
its value does not match any server name, or the request does not
contain this header field at all, then nginx will route the request to
the default server for this port. In the configuration above, the
default server is the first one — which is nginx’s standard default
behaviour. It can also be set explicitly which server should be
default, with the default_server parameter in the listen directive
When you had a www or a non-www site missing, nginx couldn't match it to any server so it sends the request to the default server, and assuming you removed the default file from sites-enabled and didn't set any as default then the default server is the first one alphabetically, if we compare marianamarques.ntr.br.conf vs fabricadevozes.com.br.conf then the winner is the one starting with an f, that's why it was showing that server instead.
And since you did the basic redirection server, let me add that you better have used return over rewrite, check taxing rewrites
server {
server_name www.example.com;
return 301 http://example.com$request_uri$is_args$query_string;
}
I want to test nginx subdomains before uploading config to the server. Can i test it on localhost? I try
server {
listen 80;
server_name localhost;
location / {
proxy_pass http://localhost:8080;
}
}
server {
listen 80;
server_name sub.localhost;
location / {
proxy_pass http://localhost:8080/sub;
}
}
And it does not work. Shoulld i change my hosts file in order to make it work? Also, after uploading site to the server should i change DNS records and add sub.mydomain.com?
Yes, add '127.0.0.1 sub.localhost' to your hosts file. That sub has to be resolved somehow. That should work.
Then once you're ready to go to the net, yes, add an a or cname record for the subdomain sub.
When I use proxy_pass I also include the proxy.conf from nginx.
http://wiki.nginx.org/HttpProxyModule
In Linux based OS just to edit as sudo /etc/hosts file and change 127.0.0.1 localhost to 127.0.0.1 *.localhost.
So at /etc/nginx/sites-enabled/<environment>/<your_project_name> edit server_name key as <subdomain>.localhost.
Reload nginx and networking service.
$ sudo service nginx reload
$ sudo service networking reload
And then try http://<subdomain>.localhost at url bar.
It works for me.
UPDATE
In my opinion, a better solution is creating a virtual server that only responds if subdomain doesn’t exist, at /etc/nginx/sites-enabled/development/default, as default server (remember that you can define only one server as default).
server {
listen 80 default_server;
root /var/www/html/errors/404;
server_name *.localhost *.<host-name>;
location / {
index subdomain.html;
}
}
Make sure that in nginx.conf (generally at /etc/nginx/nginx.conf) contain include /etc/nginx/sites-enabled/**/*; to this virtual server work. If not, put it and then run $ sudo service nginx reload.
In this case isn't necessary put *.localhost in /etc/hosts, but only localhost.
For your public webserver with its own domain name, you just need to add a Canonical name using a CNAME record in your DNS configuration:
CNAME * example.com.
Once this is done, set your nginx setting
server_name *.example.com example.com;
In your local setup you can keep the same configuration for nginx but unless you have a local DNS setup, you will have to edit your /etc/hosts file and add each subdomain manually. wildcards don't work in the /etc/hosts file.
127.0.0.1 abc.example.com def.example.com ghi.example.com
It is generally recommended to use .local as the namespace for your local domains.
With an Nginx configuration like shown by the OP, all that is needed is to configure the local DNS resolution. I run Linux containers on a VM with a local DHCP IP but test them on Windows 10 browsers.
The DNS configuration can be done by editing "C:\Windows\System32\drivers\etc\hosts" as Administrator.
192.168.100.50 sub.example.local
192.168.100.50 example.local
Of course, use 127.0.0.1 or other appropriate IP as needed.
