LDM Binary Installation

• Pre-Installment Requirement needed first

• Obtain the distribution

• Unpack the distribution

• Run the scriptconfig script

• First time installation, copy distribution configuration files

• Make rpc.ldmd and hupsyslog suid root

• Compare the working ldmadmin script with the new release ldmadmin script

• Change the runtime link

• Start the LDM

Obtain the LDM Distribution

• AIX
• HPUX
• IRIX
• Linux
• OSF1
• Solaris
• Solaris - x86

The LDM binary distributions are available via anonymous FTP from ftp://ftp.unidata.ucar.edu/pub/binary/.

Which Binary to get? Run the command:

       % uname -a
       % cd {platform-OS}
       

Get the ldm.binary.tar.Z file.

Unpack the Distribution in LDM Home Directory

       % cd ~ldm
       % zcat ldm.binary.tar.Z | tar xvf -
       

Run the scriptconfig script

• In {version-directory}/bin run the script scriptconfig to configure the perl scripts with location of perl, LDMHOME, and the fully qualified hostname.

         % cd ~ldm/{{version-directory}/bin
         % scriptconfig
         

First time installation, copy distribution configuration files

• If this is a new LDM installation, copy the contents of {version-directory}/etc to ~ldm/etc

         % cd ~ldm/{version-directory}/etc
         % cp * ~ldm/etc
         

Make rpc.ldmd and hupsyslog suid root

• Change permissions for rpc.ldmd and hupsyslog to be setuid root. This step needs to be done as root

  	% cd ~ldm/{version-directory}/bin
  	% chown root rpc.ldmd
  	% chown root hupsyslog
  	% chmod u+srwx,g+rx,o+rx rpc.ldmd
  	% chmod u+srwx,g+rx,o+rx hupsyslog
         

Compare the working ldmadmin script with the new release ldmadmin script

For an existing LDM installation:

	% cd ~ldm/{version-directory}/bin
	% {edit}  ldmadmin    # against ~ldm/bin/ldmadmin
       

Most of the standard configuration has been done:

	the location of perl
	the hostname of the machine 
	the ldm home variable  
       

It is a good time to make sure that these configurations are correct. The other parameters that need to be checked are:

	udunits path variable
	size of the product queue
	size of the pqsurf queue
	the number of ldm logs to maintain
       

Change the runtime link

• Install the runtime link

         % cd ~ldm
         % ln -s {version-directory} runtime
         

• Create an initial, empty logfile

         % cd ~ldm
         % touch logs/ldmd.log
         

For an existing LDM installation:

• Stop the LDM

         % ldmadmin stop
         

• Change the runtime link

         % cd ~ldm
         % rm runtime
         % ln -s {new-version-directory} runtime
         

Start the LDM

• Create the queue

         % ldmadmin mkqueue
         

• Start the LDM

         % ldmadmin start
         

• At this point, the LDM should be running with the new release and the distribution configuration files. Because the configuration files: ldmd.conf and pqact.conf are not tailored for your site, no data will be arriving. The next step is to configure the ldmd.conf and pqact.conf files.

For an existing LDM installation:

• Start the LDM

         % ldmadmin start
         

• At this point, the LDM should be running with the new release and the previous configuration.
