To configure a reverse proxy in Apache the conf file should be created in Apache Proxy Conf folder. You can run multiple instances of Apache Proxies on a single Server. In this example, I have created abc.xyz.com.conf file to configure the reverse proxy.
$ pwd
/etc/httpd/conf.proxies.d
$ cat abc.xyz.com.conf
--VirtualHost 63.2.77.187:80
ServerName abc.xyz.com
RedirectPermanent / https://abc.xyz.com/
--/VirtualHost
$ pwd
/etc/httpd/conf.proxies.d
$ cat abc.xyz.com.conf
ServerName abc.xyz.com
RedirectPermanent / https://abc.xyz.com/
ServerName abc.xyz.com
ErrorLog logs/proxies/abc.xyz.com.err.log
CustomLog logs/proxies/abc.xyz.com.acc.log combined
--/VirtualHost
SSLEngine on
SSLProxyEngine on
SSLCertificateFile cert.d/abc.xyz.com.crt
SSLCertificateKeyFile cert.d/abc.xyz.com.key
SSLCertificateChainFile cert.d/abc.xyz.com.IntermediateCA.crt
--/IfModule ssl_module
# Proxy for /
--Location /
ProxyPass https://redirect_URL.com/
ProxyPassReverse https://redirect_URL.com/
--/Location
ProxyPass https://redirect_URL2.com/
ProxyPassReverse https://redirect_URL2.com/
--/Location
Note: The Certificates are placed in the .cert folder. IntermedaiteCA is the rootCA Certificate.
Once configuration is done. use these commands to restart or check status. A stop/start is required post any configuration changes in this file.
sudo systemctl start httpd
sudo systemctl stop httpd
sudo systemctl status httpd
