Installing Python 3.8 on SLES 15 for Cloudera Manager 7.7.3

zypper install gcc openssl-devel bzip2-devel libffi-devel zlib-devel make libbz2-devel gzip

You may install the custom Python 3.8 package in the standard location, or if required by your organization, in a custom location. Note that some commands are different depending on this choice. If using a custom location, substitute the custom location wherever you see [***CUSTOM-INSTALL-PATH**] in the instructions.

Perform the following steps on all cluster hosts:

1. SSH into the host system as a root user.
2. Download Python 3.8 and decompress the package by running the following commands:

   cd /opt
   curl -O https://www.python.org/ftp/python/3.8.12/Python-3.8.12.tgz

   tar -zxvf Python-3.8.12.tgz

3. Change directory to where you decompressed the Python 3.8 package:

   cd Python-3.8.12.tgz

4. Run one of the following command to start installing Python 3.8:
   • If you are installing to the standard location, run the following command

     ./configure --enable-shared

   • If you are installing to a custom location, run the following command:

     ./configure --enable-shared --prefix=[***CUSTOM-INSTALL-PATH***]

5. Build Python 3.8 as follows:
   1. Run the make command to compile the files:

      make

   2. Run the following command to place the compiled files in the default location or in the custom location that you specified using the --prefix option:

      make altinstall

   3. Copy the shared compiled library files (libpython3.8.so) to the /lib64/ directory:

      cp --no-clobber ./libpython3.8.so* /lib64/

      The --no-clobber option is used to prevent overwriting of files.
   4. Change the permissions of the libpython3.8.so files as follows:

      chmod 755 /lib64/libpython3.8.so*

6. If you see the error while loading shared libraries: libpython3.8.so.1.0: cannot open shared object file: No such file or directory error, then run the following command:

   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/
