117# Figure out why Zephyr isn't working. Most recently, it was because there
118# was a 64-bit RPM installed; remove it and install Joe's 32-bit one
119
120# Install the athena-base, athena-lprng, and athena-lprng-misc RPMs
121# from the Athena 9 build (these are present in our yum repo).  Note
122# that you will have to use --nodeps for at least one of the lprng
123# ones because it thinks it needs the Athena hesiod RPM.  It doesn't
124# really.  Before doing this, run it without --nodeps and arrange to
125# install the rest of the things it really does depend on.  This will
126# include a bunch of 32-bit rpms; go ahead and install the .i586 versions
127# of them.  In the case of the Kerberos libraries, you'll be told that
128# there are conflicting files with the 64-bit versions of the packages,
129# which we scriptsify.  You'll have to use --force to install those
130# rpms despite the conflicts.  After doing that, you may want to
131# install the corresponding 64-bit scriptsified versions again, just
132# to be safe in case the 32-bit versions overwrite files that differ.
133# When you try this, it will complain that you already have the same
134# version installed; again, you'll need to use --force to do it anyway.
135# Yuck.
136
137# Install the full list of RPMs that users expect to be on the
138# scripts.mit.edu servers.  See server/doc/rpm and
139# server/doc/rpm_snapshot.  (Note that this is only a snapshot, and not
140# all packages may in fact be in use.)
141
142# Check which packages are installed on your new server that are not
143# in the snapshot, and remove ones that aren't needed for some reason
144# on the new machine.  Otherwise, aside from bloat, you may end up
145# with undesirable things for security, like sendmail.
146
147# Check out the scripts /usr/vice/etc configuration
148    cd /root
149    mkdir vice
150    cd vice
151    svn co svn://scripts.mit.edu/trunk/server/fedora/config/usr/vice/etc etc
152    \cp -a etc /usr/vice
153
154# Install the full list of perl modules that users expect to be on the
155# scripts.mit.edu servers.
156# - export PERL_MM_USE_DEFAULT=1
157# - Run 'cpan', accept the default configuration, and do 'o conf
158#   prerequisites_policy follow'.
159# - Parse the output of perldoc -u perllocal | grep head2 on an existing
160#   server, and "notest install" them from the cpan prompt.
161# TO DO THIS:
162# On another server, run:
163# perldoc -u perllocal | grep head2 | cut -f 3 -d '<' | cut -f 1 -d '|' | sort -u | perl -ne 'chomp; print "notest install $_\n" if system("rpm -q --whatprovides \"perl($_)\" >/dev/null 2>/dev/null")' > /mit/scripts/config/perl-packages.txt
164# Then on the server you're installing,
165#    cat perl-packages.txt | perl -MCPAN -e shell
166
167# Install the Python eggs and Ruby gems and PEAR/PECL doohickeys that are on
168# the other scripts.mit.edu servers and do not have RPMs.
169# - Look at /usr/lib/python2.6/site-packages and
170#           /usr/lib64/python2.6/site-packages for Python eggs and modules.
171#   First use 'yum search' to see if the relevant package is now available
172#   as an RPM, and install that if it is.  If not, then use easy_install.
173# - Look at `gem list` for Ruby gems.
174#   Again, use 'yum search' and prefer RPMs, but failing that, 'gem install'.
175# - Look at `pear list` for Pear fruits (or whatever they're called).
176#   Yet again, 'yum search' for RPMs before resorting to 'pear install'.  Note
177#   that for things in the beta repo, you'll need 'pear install package-beta'.
178# - Look at `pecl list` for PECL things.  'yum search', and if you must,
179#   'pecl install' needed items.

181# echo 'import site, os.path; site.addsitedir(os.path.expanduser("~/lib/python2.6/site-packages"))' > /usr/lib/python2.6/site-packages/00scripts-home.pth
182
183# Install the credentials.  There are a lot of things to remember here:
184#   o You probably installed the machine keytab long ago
185#   o Use ktutil to combine the host/scripts.mit.edu and
186#     host/scripts-vhosts.mit.edu keys with host/this-server.mit.edu in
187#     the keytab.  Do not use 'k5srvutil change' on the combined keytab
188#     or you'll break the other servers.
189#   o The daemon.scripts keytab
190#   o The SSL cert private key
191#   o The LDAP password for the signup process
192#   o The SQL password for the signup process
193#   o The LDAP keytab for this server, which will be used later
194#   o Replace the ssh host keys with the ones common to all scripts servers
195#   o You'll install an LDAP certificate signed by the scripts CA later
196#   o Make sure root's .k5login is correct
197#   o Make sure logview's .k5login is correct
198
199# If you are setting up a test server, pay attention to
200# /etc/sysconfig/network-scripts and do not bind scripts' IP address.
201# You will also need to modify /etc/ldap.conf, /etc/nss-ldapd.conf,
202# /etc/openldap/ldap.conf, and /etc/httpd/conf.d/vhost_ldap.conf to
203# use scripts.mit.edu instead of localhost.
204
205# Install fedora-ds-base and set up replication (see ./HOWTO-SETUP-LDAP
206#   and ./fedora-ds-enable-ssl-and-kerberos.diff).
207
208# Make the services dirsrv, nslcd, nscd, postfix, and httpd start at
209# boot. Run chkconfig to make sure the set of services to be run is
210# correct.
211
212# cd /etc/postfix; postmap virtual
213# Otherwise postfix will appear to work, but actually not deliver mail
214
215# Run fmtutil-sys --all, which does something that makes TeX work.
216
217# Ensure that PHP isn't broken:
218# # mkdir /tmp/sessions
219# # chmod 01777 /tmp/sessions
220
221# Reboot the machine to restore a consistent state, in case you
222# changed anything.
223
224# (Optional) Beat your head against a wall.
225
226# Possibly perform other steps that I've neglected to put in this
227# document.
