First login into your server with the root login credentials
cd /home/cpapachebuild/buildapache/apache_1.3.31/src/modules/proxy/
or
cd /home/cpeasyapache/src/httpd-2.0.63/modules/proxy
Then run the command:
/usr/local/apache/bin/apxs -i -c *.c
Add the following module to the httpd.conf to load the proxy module with the httpd configuration file:
LoadModule proxy_module libexec/mod_proxy.so
And then restart the Apache service:
service httpd restart
or
/etc/init.d/httpd restart
Now check proxy installed or not on the server using the following command.
/usr/local/apache/bin/httpd -l | grep proxy
