Why Web Server Packages and Modules Should Be Updated?

Web servers should be protected against ever-changing security threats and kept at peak performance. For that reason, it is extremely important to keep server packages and modules up to date.

Advantages of Update:

Closing of Security Vulnerabilities

Performance Improvements

Availability of New Features

Increased Stability and Reliability

Process of Updating Package and Module

Apache Web Server Package and Module Update

First, before doing the update, check your current version:

apache2 -v
Then, upgrade the machine:

sudo apt update && sudo apt upgrade apache2
Next, update the Apache modules:

sudo a2enmod rewrite headers ssl
sudo systemctl restart apache2
Apache Compilation and Customization

You can follow the following instructions to build Apache with your own configuration:

Install the required packages:

sudo apt install build-essential libpcre3 libpcre3-dev libssl-dev
Download and compile the Apache source code:

wget https://downloads.apache.org/httpd/httpd-2.4.58.tar.gz
tar -xzvf httpd-2.4.58.tar.gz
cd httpd-2.4.58
sudo ./configure --enable-ssl --enable-so --enable-rewrite
sudo make
sudo make install
Update Nginx Web Server Packages and Modules

Check the version you are currently on:

nginx -v
Update:

sudo apt update && sudo apt upgrade nginx
Update and enable Nginx modules:

sudo apt install libnginx-mod-http-headers-more-filter
sudo systemctl restart nginx
Nginx Compilation and Customization

For installation with custom modules:

Install dependencies:

sudo apt install build-essential libpcre3 libpcre3-dev libssl-dev zlib1g-dev
Download and compile the source code:

wget https://nginx.org/download/nginx-1.25.0.tar.gz
tar -xzvf nginx-1.25.0.tar.gz
cd nginx-1.25.0
sudo ./configure --with-http_ssl_module --with-http_v2_module --with-stream
sudo make
sudo make install
Optimization Steps

Performance Optimization:

Achieve better performance by optimizing the Apache and Nginx configuration files.

Reduce memory usage by disabling unnecessary modules.

Make full use of caching mechanisms (e.g. mod_cache, proxy_cache).

Security Optimization:

Enable and configure security modules (like ModSecurity).

Tighten up your SSL/TLS configuration and organize certificate management.

Apply security patches and upgrades in a timely fashion.
