LDM RPM Installation
Introduction
First, let me acknowledge that I am not an RPM expert. Consequently, if you have a suggestion on how to improve
the RPM installation process, then please send it to
support-ldm@unidata.ucar.edu.
Installing from an RPM is, necessarily, less flexible than installing from source. In particular, the following
constraints apply:
- Not all platforms are supported. Supported ones are encoded within the name of the RPM file.
- If the LDM user doesn't exist, then they will be created with the name
"ldm", with default user and group ID-s, and with the value of rpm(1)'s prefix option as their
home-directory.
- All utilities will be dynamically linked and only the sharable LDM library will be installed.
- The top-level LDM server, ldmd, will listen on
port 388.
- The "local0" logging facility will be used.
Installations Steps
- Become the superuser (i.e., "root").
- Download the appropriate RPM from
https://downloads.unidata.ucar.edu/ldm/.
- Install the package with the command
rpm --install [--prefix=ldmhome] rpm-file
where rpm-file is the RPM file that you just downloaded. The square brackets denote an optional argument
in which ldmhome is the home-directory of the LDM user. The default
home-directory is /home/ldm. This option must be used if
- An LDM user account exists on the platform with a home-directory that differs from the default; or
- An LDM user account doesn't exist on the platform and you want the LDM user to have a home-directory that
differs from the default.
