The OpenSSL project is a collaborative effort to develop a robust, commercial-grade, full-featured, and open source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library. The project is managed by a worldwide community of volunteers that use the internet to communicate, plan, and develop the OpenSSL toolkit and its related documentation. For more information, visit http://www.openssl.org.
The OpenSSL library will be used by Nginx to serve secure web pages. We thus need to install the library and its development package. The process remains the same here – you install openssl and openssl-devel:
[[email protected] ~]# yum install openssl openssl-devel
Using apt-get, execute the following command:
[[email protected] ~]# apt-get install openssl libssl-dev
Please be aware of the laws and regulations in your own country. Some countries do not allow the use of strong cryptography. The author, publisher, and the developers of the OpenSSL and Nginx projects will not be held liable for any violations or law infringements on your part.
Now that you have installed all of the prerequisites, you are ready to download and compile the Nginx source code.
