How To Install OpenSSL 3 on Centos 7

In this guide, we want to teach you to Install OpenSSL 3 on Centos 7.

OpenSSL is an open-source command line tool that is commonly used to generate private keys, create CSRs, install your SSL/TLS certificate, and identify certificate information. Operating systems and many applications use OpenSSL to provide secure communication over the internet.

The version of OpenSSL available on Centos 7 is a bit old and some applications will give errors when compiling if it requires a newer release. So we want to show you to install the latest release of OpenSSL on Centos 7.

Steps To Install OpenSSL 3 on Centos 7

To complete this guide, you must log in to your server as a non-root user with sudo privileges. To do this, you can follow our guide on Initial Server Setup with Centos 7.

Set up OpenSSL 3.0 on Centos 7

First, you need to update your local package index with the command below:

sudo yum update -y

Then, use the following command to install the Development Tools:

sudo yum groupinstall "Development Tools" -y

Also, install the following packages:

sudo yum install perl-IPC-Cmd perl-Test-Simple -y

Download OpenSSL From Source

At this point, you need to visit the GitHub OpenSSL Releases page and get the latest release by using the wget command:

sudo wget https://github.com/openssl/openssl/releases/download/openssl-3.0.8/openssl-3.0.8.tar.gz

Then, extract your downloaded file by using the command below:

sudo tar xvf openssl-3.0.8.tar.gz

Next, navigate to your OpenSSL directory:

cd openssl-3.0*/

Next, use the following commands to build OpenSSL 3.0:

# make
# make test
# make install

Update links and caches by using the command below:

sudo ldconfig

Then, update your system-wide OpenSSL configuration:

sudo tee /etc/profile.d/openssl.sh<<EOF
export PATH=/usr/local/openssl/bin:\$PATH
export LD_LIBRARY_PATH=/usr/local/openssl/lib:\$LD_LIBRARY_PATH
EOF

Reload shell environment:

source /etc/profile.d/openssl.sh

Verify your OpenSSL installation on Centos 7 by checking its version:

openssl version

Output
OpenSSL 3.0.8 7 Feb 2023 (Library: OpenSSL 3.0.8 7 Feb 2023)
