Apache reverse proxy with basic authentication

Try开发者_StackOverflowing to configure my reverse proxy with basic authentication before forward the traffic to my back end server. Can any one give me a solution.

Example here:

User(internet) -> reverse proxy / vhosts server (need to add basic authentication here ) -> back end server ( non authenticated )

You can follow the instructions here: Authentication, Authorization and Access Control. The main difference for your reverse proxy is that you'll want to put the auth stuff inside a Location block, even though the docs say that they're only allowed in Directory blocks:

<Location />
    AuthType Basic
    ...
</Location>

Outside the Location block you can put your proxy commands, such as:

ProxyPass / http://localhost:8080/

First, check if your apache2 has the utils package

sudo apt-get install apache2-utils

Then, set the username and password.

sudo htpasswd -c /etc/apache2/.htpasswd <username>

After that, edit your reverse proxy to use the authentication

<VirtualHost *:80>
    ProxyPreserveHost On

    ProxyPass / http://someaddress:1234/
    ProxyPassReverse / http://someaddress:1234/

    Timeout 5400
    ProxyTimeout 5400

    ServerName dev.mydomain.com
    ServerAlias *.dev.mydomain.com

    <Proxy *>
        Order deny,allow
        Allow from all
        Authtype Basic
        Authname "Password Required"
        AuthUserFile /etc/apache2/.htpasswd
        Require valid-user
    </Proxy>
</virtualhost>

At least, update your apache

sudo service apache2 reload

Here's the config I have used to accomplish basic authentication over https against a database. My backend server is running Tomcat and I connect to it using AJP. The funny port number (4443) is because the standard port (443) was already used, and I didn't want to configure several https services on the same port.

<IfModule mod_ssl.c>
NameVirtualHost *:4443
<VirtualHost *:4443>
        ServerAdmin webmaster@localhost
        ServerName ws.myserver.se
        ServerAlias ws.myserveralias.se
