Reverse Proxy Setup

Reverse Proxy Setup

for Nginx and Apache

Local usage

(a normal reverse tunnel: ssh -R 61001:localhost:22 user@myhost.tld)

Asuming your local application runs on port 3000 (http://localhost:3000/ in the browser shows your nice webpage) we login with a user noroot and the ssh port 22 on the host myhost.tld to forward that to the server port 61001. Being logged in on the the server noroot@myhost.tld:22 the command curl -v http://localhost:61001/ should be equal to on the local machine http://localhost:300
just run: ssh -i ~/.ssh/server.key -l noroot -p 22 myhost.tld -R 61001:localhost:3000

Apache Setup

Enable mod_rewrite (in case you dont have it yet enabled) and mod_proxy with some sub modules:

a2enmod rewrite
a2enmod proxy
a2enmod proxy_connect
a2enmod proxy_http

and restart Apache /etc/init.d/apache2 restart or service apache2 restart.

An .htaccess could look like:

RewriteEngine on
RewriteRule ^srv/(.*) http://localhost:61001/$1 [P]

don't forget the [P] flag

And a mod_virtualhost conf in the sites-enabled/ directory could look like:

<VirtualHost *:*>
    ProxyPreserveHost On

    # ProxyPass / http://[IP ADDR]:[PORT]/
    # ProxyPassReverse / http://[IP ADDR]:[PORT]/
    
    ProxyPass / http://0.0.0.0:8080/
    ProxyPassReverse / http://0.0.0.0:8080/

    ServerName localhost
</VirtualHost>

And the SSL virtual host conf would look like:

Listen 443
NameVirtualHost *:443
<VirtualHost *:443>
    SSLEngine On
    SSLCertificateFile /etc/apache2/ssl/cert.pem
    ProxyPass / http://0.0.0.0:8080/
    ProxyPassReverse / http://0.0.0.0:8080/
</VirtualHost>
