Installing WordFence-cli on RHEL/AlmaLinux

/ Hosting, Linux, WordPress / By

The WordFence-cli has the following requirements:

Python >= 3.8
The C library libpcre >= 8.38
Python packages:
packaging >= 21.0
requests >= 2.3


First we will need to install libffi-devel and pcre-devel before compiling python3.8

yum install pcre-devel libffi-devel ncurses-devel -y

As we’ll install Python from source, let’s install the packages required for Python installation.

sudo yum -y install epel-release
sudo yum -y update

Reboot after the upgrade

sudo reboot

After the reboot, install build dependencies

sudo yum -y groupinstall "Development Tools"
sudo yum -y install openssl-devel bzip2-devel libffi-devel xz-devel

Confirm gcc is available:

$ gcc --version
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39)

Step 2: Download latest Python 3.8 Archive

Now download the latest archive of Python 3.8 release.

VERSION=3.8.18
sudo yum -y install wget
wget https://www.python.org/ftp/python/$VERSION/Python-$VERSION.tgz

Extract the package.

tar xvf Python-$VERSION.tgz

Change the created directory:

cd Python-$VERSION/

Step 3: Install Python 3.8 on CentOS 7 / CentOS 8

Setup installation by running the configure script.

./configure --enable-optimizations

Initiate compilation of Python 3.8 on CentOS 7.

sudo make altinstall

If this was successful, you should get a message like below:

.....

copying build/scripts-3.8/idle3.8 -> /usr/local/bin

		$ensurepip --root=/ ; \

Step 4: Check Python 3.8 on CentOS 8 / CentOS 7.

Confirm that the installation of Python 3.8 on CentOS 8 / CentOS 7 was successful.

$ python3.8 --version
Python 3.8.18

Pip is also installed.

$ pip3.8 --version
pip 19.2.3 from /usr/local/lib/python3.8/site-packages/pip (python 3.8)

Installing WordFence-cli

Now we are going to run:

python3.8 -m pip install wordfence

Try running: wordfence

If you encounter following error:

Run:

python3.8 -m pip install urllib3==1.26.6

Run: wordfence --version
