Lab Directory Infrastructure

Most packages typically require one of the following types of installs:

  • API only install (e.g., jython, doxygen)
  • server only install (e.g., apache)
  • API and server install (e.g., MySQL, OpenLDAP)

All package APIs are installed within /l/esysadm/packages. The install location of a server varies on the type of installation:

  1. lab installation: One server can serve the whole lab (e.g., MySQL, LDAP). In this case install server locally to rainier at /usr/local since the files do not need to be accessible to other machines. Furthermore, often these files require root protection and root privileges do not carry across NFS.

  2. individual installation: Server needs to be deployed to two or more machines in the lab.
    1. root-protected files: If files need to be root read-only or some other form of root protection, do a local deployment at /usr/local for each machine. Again, root privileges do not carry across NFS.
    2. no protection: If there are no special permissions needed on the server files, go ahead and do a global server install at /l/esysadm/packages.

If you want a server to boot up when a machine is rebooted, usually server scripts are placed in the startup directory /etc/init.d/rc.d. CSG has instead placed a special script in the /etc/init.d directory called where we can place calls to server scripts. The advantage of this approach is that the calls to the script have been placed in the appropriate run directories. Furthermore, this will allow us to track all the changes that the extreme lab makes in one place. Therefore, please use the script.

Important Notes

  • DO NOT CONFIGURE ON XRAID! It is very important that you configure a package from a machine which nfs mounts xraid's user1 disk. For packages that hard code their installation path, if you configure on xraid, /home/user1 will be hard coded into the installation and no other machines will be able to use it (since /home/user1 does not exist on the other machines; at least not as it does on xraid).

  • Note that if you have to change any system configuration files (i.e., any files in /etc) such as inetd.conf, let the CSG know. CSG maintains versions of most system configuration files at a central location and will need to update their version.
