How to configure apache with proxy_mod for domains redirect - apache

Question

I have a server with only one IP adress but a lot of domain (and sub-doman) but every domain have dedicated virtual machine on my Host Server.
I try to use mod_proxy for ProxyPass and Reverse request and, in apache conf i make it:
<VirtualHost *:80>
ServerAlias mydomain.domain.com
ProxyRequests Off
<Proxy />
Order deny,allow
Allow from all
ProxyPass http://192.168.1.8/
ProxyPassReverse http://192.168.1.8/
</Proxy>
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined
ErrorLog ${APACHE_LOG_DIR}/error.log
</VirtualHost>
<VirtualHost *:80>
ProxyRequests Off
ServerAlias domain.domain2.org
ServerAlias subdomanin.domain.com
DocumentRoot /var/www
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory>
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined
ErrorLog ${APACHE_LOG_DIR}/error.log
</VirtualHost>
In this conf:
domain.domain1.com -> go to 192.168.1.8
subdomanin.domain1.com and another domain -> go to document root.
With ProxyRequests On and "Allow from All" (this conf), apache is an openproxy...
With this config (and ProxyRequest Off), if someone request "www.google.it" with proxy mydomain.domain.com he don't have google but server redirect it to myNumericIp
What is right config for do if http://mydomain.domain.com/some request are redirect to myNumericIp with url http://my.Numeric.Ip/some otherwhise proxy don't response anything).
I try this:
<Proxy http://mydomain.domain.com/>
Order deny,allow
Allow from all
ProxyPass http://192.168.1.8/
ProxyPassReverse http://192.168.1.8/
</Proxy>
Or this:
<Proxy />
Order deny,allow
Allow from all
ProxyPass http://192.168.1.8/
ProxyPassReverse http://192.168.1.8/
</Proxy>
<Proxy *>
Order deny,allow
Deny from all
</Proxy>
But don't work...

Answer 1

Using the following steps:
1) Update virtual file:-
<VirtualHost *:80>
ServerAdmin admin#test.com
ServerName mysite.com
ServerAlias www.mysite.com ProxyRequests Off Order deny,allow Allow from all <Location />
ProxyPass http:// mysite.com:8000/
ProxyPassReverse http:// mysite.com:8000/
</Location>
2) Enabling Necessary Apache Modules
To enable these four modules, execute the following commands in succession.
sudo a2enmod proxy
sudo a2enmod proxy_http
sudo a2enmod proxy_balancer
sudo a2enmod lbmethod_byrequests
3) To put these changes into effect, restart Apache.
sudo systemctl restart apache2
