Compiling from source
There are situations where compiling Nginx from source is preferable. It gives us the most
flexibility regarding modules, so we can customize better for our intended usage. For
example, we could compile a very lean version for embedded hardware.
Additionally, we can make sure we use the latest version of Nginx and have all new
features available to us. Keep in mind, though, that when installing software from source
you are responsible for keeping it updated. Nginx, just like every other piece of software,
sometimes finds security issues that it needs to address. An OS package is much easier to
update than a source install, but so long as you're aware of the need to maintain it yourself,
there is absolutely no problem.
Depending on the optional modules that you select at compile time, you will perhaps need
different prerequisites. We will guide you through the process of installing the most
common ones, such as GCC, PCRE, zlib, and OpenSSL
