230# Install the Python eggs and Ruby gems and PEAR/PECL doohickeys that are on
231# the other servers and do not have RPMs.
232# The general mode of operation will be to run the "list" command
233# on both servers, see what the differences are, check if those diffs
234# are packaged up as rpms, and install them (rpm if possible, native otherwise)
235# - Look at /usr/lib/python2.6/site-packages and
236#           /usr/lib64/python2.6/site-packages for Python eggs and modules.
237#   There will be a lot of gunk that was installed from packages;
238#   easy-install.pth will tell you what was easy_installed.
239#   First use 'yum search' to see if the relevant package is now available
240#   as an RPM, and install that if it is.  If not, then use easy_install.
241# - Look at `gem list` for Ruby gems.
242#   Again, use 'yum search' and prefer RPMs, but failing that, 'gem install'.
243#       ezyang: rspec-rails depends on rspec, and will override the Yum
244#       package, so... don't use that RPM yet
245# - Look at `pear list` for Pear fruits (or whatever they're called).
246#   Yet again, 'yum search' for RPMs before resorting to 'pear install'.  Note
247#   that for things in the beta repo, you'll need 'pear install package-beta'.
248#   (you might get complaints about the php_scripts module; ignore them)
249# - Look at `pecl list` for PECL things.  'yum search', and if you must,
250#   'pecl install' needed items.
251    # Automating this... will require a lot of batonning between
252    # the servers. Probably best way to do it is to write an actual
253    # script.
255# Setup some Python config

265# Install the credentials.  There are a lot of things to remember here:

267#   o Use ktutil to combine the host/ and
268#     host/ keys with host/ in
269#     the keytab.  Do not use 'k5srvutil change' on the combined keytab
270#     or you'll break the other servers.
271#   o The daemon.scripts keytab
272#   o The SSL cert private key
273#   o The LDAP password for the signup process
274#   o The SQL password for the signup process
275#   o The LDAP keytab for this server, which will be used later
276#   o Replace the ssh host keys with the ones common to all scripts servers
277#   o You'll install an LDAP certificate signed by the scripts CA later
278#   o Make sure root's .k5login is correct
279#   o Make sure logview's .k5login is correct
281# If you are setting up a test server, pay attention to
282# /etc/sysconfig/network-scripts and do not bind scripts' IP address.
283# You will also need to modify /etc/ldap.conf, /etc/nss-ldapd.conf,
284# /etc/openldap/ldap.conf, and /etc/httpd/conf.d/vhost_ldap.conf to
285# use instead of localhost.
287# Install fedora-ds-base and set up replication (see ./HOWTO-SETUP-LDAP
288#   and ./fedora-ds-enable-ssl-and-kerberos.diff).
290# Make the services dirsrv, nslcd, nscd, postfix, and httpd start at
291# boot. Run chkconfig to make sure the set of services to be run is
292# correct.
294# Postfix doesn't actually deliver mail; fix this
