The best way I found is to use the texlive offical installation tool to install the full packages for texlive 2016. It will take around 4.5GB.
First, remove existing texlive packages if they are installed:
# yum erase texlive texlive*
Then download installation package from its website.
And execute the installation tools in the decompressed package:
It will download and install the packages/tools for texlive.
After it is done, set the path in your
~/.bashrc or a global location accordingly:
/opt/texlive/ is the path you chose to install texlive. If you choose another location, you can replace it with the one you used.
