November 3, 2022
Struggling with a high-traffic website, when there are no performance issues? Then no worries now with Apache load balancer you can manage high-traffic websites hassle-free. (Setup is based on Ubuntu/Debian systems, if you need assistance click here – Get Assistance).
You can follow the below steps to configure the Apache load balancer for
your website to avoid high traffic.
Step 1: Install Apache Modules
To configure the Apache load balancer, we require four Apache modules:
mod_proxy: The primary proxy module that redirects traffic and
enables Apache to serve as a gateway to backend servers.
mod_proxy_http: Allows proxying HTTP
mod_proxy_balancer and mod_lbmethod_byrequests: Add a load balancing
support to the Apache web server.
To install the required Apache modules, open a terminal and run the
ProxyPreserveHost– It informs Apache to
retain the original host header and pass it on to back-end servers.
ProxyPass – Primary proxy directive.
This specifies that everything under root (/) should be sent to a server
back-end cluster of servers. When Apache receives a request for /example, it
sends it to http://your backend server/example.
ProxyPassReverse – informs Apache to change
the response header in the response received from the back-end server. If the
back-end server returns a location redirect response, then the client will be
redirected to the Apache proxy server rather than the back-end server.
Note: The backend server in the Proxy tag is mentioned as balancer://myclustera and inside the Proxy tag each backend server is mentioned as BalancerMember.You can have one or more BalancerMember.
