Apache 2.2 Reverse Proxy Configuration and Use

Apache 2.2 Reverse Proxy Configuration and Use

Today I'm going to talk to you about configuring and using reverse proxies with Apache 2.2. Isn't it a bit exciting? (Laughs)

What is a reverse proxy?

First of all, we need to figure out what the reverse proxy is in the end. Take an example to explain it. Suppose you are a little cutie in the sea with a small raft, suddenly encountered a fierce shark, scared little tail trembling. But, luckily, you spot a big brother on the shore who has a mighty face and looks very capable of fighting. So you ask him to help you keep the shark away. This big brother is your reverse proxy! He will receive your request first and then help you to fight the shark. When Big Brother has finished with the shark, he will bring back the result to you. Don't you think this big brother is really a good guy? (Smiling)

Why use a reverse proxy?

The role of the reverse proxy is not limited to helping you repel sharks! It has a lot more important roles to play.

Hide real server IP

I've heard that the IP of the server is a very important thing, if the ulterior motive of the people learned, they can invade your server. But we do not want to let the ulterior motives of the people to make trouble, right? Then reverse proxy can help you. It will intercept all the requests to you, and then forwarded to the actual server, so that your server's IP will be successfully hidden! No one can find your server anymore! Ha ha ha! (LAUGHING)

load balancing

Sometimes we run into a problem. It's that the servers are too busy, a server can't carry everyone's requests, and as a result, everyone gets upset and they all start complaining that the site won't open. This is intolerable! So, we need a reverse proxy to help share the pressure. It will forward the requests to multiple servers according to a load balancing algorithm and let them share the pressure so that everyone can visit the site happily!

How do I configure a reverse proxy?

Well, now we talk about how to configure Apache 2.2 reverse proxy. First of all, you have to install Apache 2.2 version, this step to do it yourself, oh, do not need me to manage. After the installation, we can start to configure.

Open your Apache configuration file, usually at: /etc/httpd/conf/httpd.conf. Find the following configuration and uncomment it:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

Then, add the following configuration to the end of the file:

ProxyRequests Off

ProxyPass "/foo" "http://localhost:8080/foo"
ProxyPassReverse "/foo" "http://localhost:8080/foo"

These lines of code are very important, don't make a mistake! (laughs) Here "/foo" is the URL path you want to set, "http://localhost:8080/foo" is the actual server address. You can modify these configurations to suit your needs.

Once configured, restart the Apache server with the command:

“`
sudo service httpd restart

Hey, after the configuration, your reverse proxy can work normally! Now you can accomplish all kinds of tasks with ease!

summarize

Today we have learned the configuration and use of reverse proxy for Apache version 2.2. By using a reverse proxy, we can hide the server IP, achieve load balancing, and improve the stability and security of the site. The process of configuring a reverse proxy may seem a bit tedious, but as long as you follow my steps, I believe we can easily get it done! I hope you have learned useful knowledge, there are problems at any time to find me Oh! Thank you all! Let's cheer together!
