Re: Installation of PostGIS without internet or with limited internet access

Hi, we need to install PostGIS on a RHEL 8 server, which contains highly sensitive information and therefore does not have internet access.

So, we attempted an offline installation but were unsuccessful.

As an alternative, we enabled internet access to specific required sites for the installation, for example:

• https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
• https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
• https://cdn.redhat.com/content/dist/rhel8/8/x86_64/appstream/os/repodata/repomd.xml
• https://mirrors.fedoraproject.org/metalink?repo=epel-8&arch=x86_64&infra=$infra&content=$contentdir

It's worth noting that this alternative also didn't work, as several errors occurred.

So, we have the following questions:

1. Is it possible to perform an offline installation of PostGIS? If so, how?
2. Is it possible to obtain a list of all the required sites during the installation of PostGIS? This way, it would be possible to enable internet access only for these sites.
