source: branches/fc13-dev/server/doc/install-howto.sh @ 1619

Last change on this file since 1619 was 1619, checked in by ezyang, 11 years ago
Miscellaneous updates to our installation document. In particular: * Minimal installs (introduced in Fedora 13) allow you to avoid having to disable a bunch of gunk. * We do checkouts from scripts.mit.edu these days, not some arbitrarily chosen source server. * make install-deps may silently fail to install some packages * scripts-build needs to be in the mock group * Docs on how to turn passworded auth back on for new Fedora release development * Pointer to the new upgrade-tips documentation

272# Install the Python eggs and Ruby gems and PEAR/PECL doohickeys that are on

274# The general mode of operation will be to run the "list" command
275# on both servers, see what the differences are, check if those diffs
276# are packaged up as rpms, and install them (rpm if possible, native otherwise)
277# - Look at /usr/lib/python2.6/site-packages and
278#           /usr/lib64/python2.6/site-packages for Python eggs and modules.
279#   There will be a lot of gunk that was installed from packages;
280#   easy-install.pth will tell you what was easy_installed.
281#   First use 'yum search' to see if the relevant package is now available
282#   as an RPM, and install that if it is.  If not, then use easy_install.
283#   Pass -Z to easy_install to install them unzipped, as some zipped eggs
284#   want to be able to write to ~/.python-eggs.  (Also makes sourcediving
285#   easier.)
286# - Look at `gem list` for Ruby gems.
287#   Again, use 'yum search' and prefer RPMs, but failing that, 'gem install'.
288#       ezyang: rspec-rails depends on rspec, and will override the Yum
289#       package, so... don't use that RPM yet
290# - Look at `pear list` for Pear fruits (or whatever they're called).
291#   Yet again, 'yum search' for RPMs before resorting to 'pear install'.  Note
292#   that for things in the beta repo, you'll need 'pear install package-beta'.
293#   (you might get complaints about the php_scripts module; ignore them)
294# - Look at `pecl list` for PECL things.  'yum search', and if you must,
295#   'pecl install' needed items. If it doesn't work, try 'pear install
296#   pecl/foo' or 'pecl install foo-beta' or those two combined.
297    # Automating this... will require a lot of batonning between
298    # the servers. Probably best way to do it is to write an actual

310#     the keytab.  Do not use 'k5srvutil change' on the combined keytab
311#     or you'll break the other servers. (real servers only)
312#   o The daemon.scripts keytab
313    ls -l /etc/daemon.keytab
314#   o The SSL cert private key (real servers only)
315#   o The LDAP password for the signup process (real servers only)
316#   o The SQL password for the signup process (real servers only)
317#   o The whoisd password (real servers only)
318#   o The LDAP keytab for this server, which will be used later (real servers only)
319#   o Replace the ssh host keys with the ones common to all scripts servers (real servers only)
320#   o You'll install an LDAP certificate signed by the scripts CA later (real servers only)
321#   o Make sure root's .k5login is correct
