Installing Dependencies

Install the required dependencies.

On CentOS 7.6/openEuler 20.03:

         
              yum install -y autoconf automake jemalloc-devel libedit-devel libtool ncurses-devel pcre-devel pkgconfig python-docutils python-sphinx graphviz httpd wget

On CentOS 8.1:

yum install -y autoconf automake libtool ncurses-devel pcre-devel pkgconfig python3-docutils graphviz httpd wget

Download Python 3.6, then compile and install it. (Python 3 in CentOS 8.1 and openEuler is later than 3.6 and does not need to be installed.)

Obtain the Python 3.6 source code and copy it to the /home directory on the server.

If the server is connected to the Internet, you can run the wget command to download the source code.

           
                cd /home/
wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz --no-check-certificate

Create an installation directory python3. Decompress the source package and go to the decompressed directory.

         
              mkdir /usr/local/python3 && tar -zxvf Python-3.6.0.tgz && cd Python-3.6.0

Configure, compile, and install Python.

         
              ./configure --prefix=/usr/local/python3  && make -j60 && make install

Set environment variables to be effective.

         
              echo export PATH=$PATH:/usr/local/python3/bin >> /etc/profile && source /etc/profile

Verify the Python 3.6 installation.

python3 --version
If the Python version is Python 3.6.0, the installation is successful.

Install pip (required only on CentOS 8.1).

Download the pip installer script.

         
              cd /home/
wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate

pip -V

Install Sphinx (required only on CentOS 8.1).

       
            pip install -U sphinx

If the pip install -U sphinx command times out, set the timeout period, for example, 100 seconds or longer.

         
              pip install --default-timeout=1000 -U sphinx

Install libedit-devel (required only on CentOS 8.1).

Download the libedit-devel RPM installation package.

         
              wget http://mirror.centos.org/centos/8/PowerTools/aarch64/os/Packages/libedit-devel-3.1-23.20170329cvs.el8.aarch64.rpm --no-check-certificate

Install libedit-devel.

         
              rpm -ivh libedit-devel-3.1-23.20170329cvs.el8.aarch64.rpm
