Lets say i have domain abc.com which redirects my server ip 1.2.3.4
i have 3 websites running on my server using docker container,

2nd website ip 1.2.3.4:60/b
3rd website ip 1.2.3.4:70/c

i want to use my domain to run these three websites.
e.g.

location /a {
rewrite ^/a(.*)$ http://1.2.3.4:50/a redirect;
}
location /b {
rewrite ^/b(.*)$ http://1.2.3.4:60/b redirect;
}
but it is redirecting and displaying the port in the url

Answer 1

Try this to solve your problem
location /a {
proxy_pass http://1.2.3.4:50;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
location /b {
proxy_pass http://1.2.3.4:60;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
location /c {
proxy_pass http://1.2.3.4:70;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
For your information, this proxy configuration will make your abc.com/a to access the root of your http://1.2.3.4:50 website. But the /a will also be passed to the http://1.2.3.4:50 so you don't have to bother add http://1.2.3.4:50/a for each proxy
You can configure it explicitly inside the nginx.conf
// Nginx.conf
http {
...
server {
server_name abc.com;
// here is location ...
}
}
Or by including configurations in sites-available, usually in the nginx.conf you can found this section:
// Nginx.conf
http {
...
include /etc/nginx/sites-available/*;
...
}
Then you can add site.conf or main.conf, you name it yourself for example in sites-available folder that has this kind of configuration:
server {
server_name abc.com;
// here is location ...
}
