1# This document is a how-to for installing a Fedora scripts.mit.edu server.
2# It is semi-vaguely in the form of a shell script, but is not really
3# runnable as it stands.
4
5# Notation
6# [PRODUCTION] Production server that will be put into the pool
7# [WIZARD]     Semi-production server that will only have
8#              daemon.scripts-security-upd bits, among other
9#              restricted permissions
10# [TESTSERVER] Completely untrusted server
11
12# 'branch' is the current svn branch you are on.  You want to
13# use trunk if your just installing a new server, and branches/fcXX-dev
14# if your preparing a server on a new Fedora release.
15branch="trunk"
16
17# 'server' is the public hostname of your server, for SCP'ing files
18# to and from.
19server=YOUR-SERVER-NAME-HERE

21# ----------------------------->8--------------------------------------
22#                       FIRST TIME INSTRUCTIONS
23#
24# [PRODUCTION] If this is the first time you've installed this hostname,
25# you will need to update a bunch of files to add support for it. These
26# include:
27#   o Adding all aliases to /etc/httpd/conf.d/scripts-vhost-names.conf
28#     (usually this is hostname, hostname.mit.edu, h-n, h-n.mit.edu,
29#     scriptsN, scriptsN.mit.edu, and the IP address.)
30#   o Adding routing rules for the static IP in
31#     /etc/sysconfig/network-scripts/route-eth1
32#   o Adding the IP address to the hosts file (same hosts as for
33#     scripts-vhost-names)
34#   o Update SSH config at
35#       - server/fedora/config/etc/ssh/shosts.equiv
36#       - server/fedora/config/etc/ssh/ssh_known_hosts
37#       - server/fedora/config/etc/ssh/sshd_config : DenyUsers
38#     (the last part is critical to ensure that rooting one server
39#     doesn't give you root to all the other servers)
40#   o Put the hostname information in LDAP so SVN and Git work
41#   o Set up Nagios monitoring on sipb-noc for the host
42#   o Set up the host as in the pool on r-b/r-b /etc/heartbeat/ldirectord.cf
43#   o Update locker/etc/known_hosts
44#   o Update website files:
45#       /mit/scripts/web_scripts/home/server.css.cgi
46#       /mit/scripts/web_scripts/heartbeat/heartbeat.php
47#
48# You will also need to prepare the keytabs for credit-card.  In particular,
49# use ktutil to combine the host/scripts.mit.edu and
50# host/scripts-vhosts.mit.edu keys with host/this-server.mit.edu in
51# the keytab.  Do not use 'k5srvutil change' on the combined keytab
52# or you'll break the other servers. (real servers only).  Be
53# careful about writing out the keytab: if you write it to an
54# existing file the keys will just get appended.  The correct
55# credential list should look like:
56#   ktutil:  l
57#   slot KVNO Principal
58#   ---- ---- ---------------------------------------------------------------------
59#      1    5 host/old-faithful.mit.edu@ATHENA.MIT.EDU
60#      2    3 host/scripts-vhosts.mit.edu@ATHENA.MIT.EDU
61#      3    2 host/scripts.mit.edu@ATHENA.MIT.EDU
62#      4    8 host/scripts-test.mit.edu@ATHENA.MIT.EDU
63#
64# The LDAP keytab should be by itself, so be sure to delete it and
65# put it in its own file.

68#                      INFINITE INSTALLATION
69
70# Start with a Scripts kickstarted install of Fedora (install-fedora)
71
72# IMPORTANT: If you are installing a server without the benefit of
73# Kickstart (for example, you are installing on XVM, it is VITALLY
74# IMPORTANT that you go through the kickstart and apply all of the
75# necessary changes--for example, disabling selinux or enabling
76# network.)
77#   XXX We should make Kickstart work for test servers too
78
79# Take updates, reboot if there's a kernel update.
80    yum update -y
81
82# Get rid of network manager (XXX figure out to make kickstarter do
83# this for us)
84    yum remove NetworkManager
85
86# Make sure sendmail isn't installed
87    yum remove sendmail
88
89# Check out the scripts /etc configuration
90    cd /root
91    \cp -a etc /
92    chmod 0440 /etc/sudoers
93
94# Make sure network is working.  Kickstart should have
95# configured eth0 and eth1 correctly; use service network restart
96# to add the new routes from etc in route-eth1.
97    systemctl restart network.service
98    # Check everything worked:
99    route
100    ifconfig
101    cat /etc/hosts
102    cat /etc/sysconfig/network-scripts/route-eth1
103
104# This is the point at which you should start updating scriptsified
105# packages for a new Fedora release.  Consult 'upgrade-tips' for more
106# information.
107    yum install -y scripts-base
108    # Some of these packages are naughty and clobber some of our files
109    cd /etc
110    svn revert resolv.conf hosts sysconfig/openafs nsswitch.conf
111    # Troubleshooting: if accountadm, tokensys and nscd fail to install
112    # you probably forgot to turn off selinux
113
114# Replace rsyslog with syslog-ng by doing:
115    rpm -e --nodeps rsyslog
116    yum install -y syslog-ng
117    systemctl enable syslog-ng.service
118
119# Install the full list of RPMs that users expect to be on the
120# scripts.mit.edu servers.
121rpm -qa --queryformat "%{Name}.%{Arch}\n" | sort > packages.txt
122# arrange for packages.txt to be passed to the server, then run:
123# --skip-broken will (usually) prevent you from having to sit through
124# several minutes of dependency resolution until it decides that
125# it can't install /one/ package.
126    yum install -y --skip-broken $(cat packages.txt)
127
128# Check which packages are installed on your new server that are not
129# in the snapshot, and remove ones that aren't needed for some reason
130# on the new machine.  Otherwise, aside from bloat, you may end up
131# with undesirable things for security, like sendmail.
132    rpm -qa --queryformat "%{Name}.%{Arch}\n" | grep -v kernel | sort > newpackages.txt
133    diff -u packages.txt newpackages.txt | grep -v kernel | less
134    # here's a cute script that removes all extra packages
135    yum erase -y $(grep -Fxvf packages.txt newpackages.txt)
136    # 20101208 - Mysteriously we manage to get these extra packages
137    # from kickstart: mcelog mobile-broadband-provider-info
138    # ModemManager PackageKit
139
140# We need an upstream version of cgi which we've packaged ourselves, but
141# it doesn't work with the haskell-platform package which expects
142# explicit versions.  So temporarily rpm -e the package, and then
143# install it again after you install haskell-platform.  [Note: You
144# probably won't need this in Fedora 17 or something, when the Haskell
145# Platform gets updated.] [It's not obvious to me that this actually
146# works]
147    rpm -e ghc-cgi-devel ghc-cgi
148    yum install -y haskell-platform
149    yumdownloader ghc-cgi
150    yumdownloader ghc-cgi-devel

156# Note: Since ultimately we'd like to move away from using per-language
157# package manager and all of these be RPMs, it is of questionable
158# importance how much /good/ automation for these is necessary.
159
160# Warning: For a new release, we're supposed to check if Fedora has
161# packaged up the RPM.  Unfortunately we don't really have good incants
162# for this.
163
164# Install the full list of perl modules that users expect to be on the

176# Install the Python eggs and Ruby gems and PEAR/PECL doohickeys that are on
177# the other scripts.mit.edu servers and do not have RPMs.
178# The general mode of operation will be to run the "list" command
179# on both servers, see what the differences are, check if those diffs
180# are packaged up as rpms, and install them (rpm if possible, native otherwise)
181# - Look at /usr/lib/python2.6/site-packages and
182#           /usr/lib64/python2.6/site-packages for Python eggs and modules.
183#   There will be a lot of gunk that was installed from packages;
184#   easy-install.pth in /usr/lib/ will tell you what was easy_installed.
185#   First use 'yum search' to see if the relevant package is now available
186#   as an RPM, and install that if it is.  If not, then use easy_install.
187#   Pass -Z to easy_install to install them unzipped, as some zipped eggs
188#   want to be able to write to ~/.python-eggs.  (Also makes sourcediving
189#   easier.)
190# 'easy_install AuthKit jsonlib2 pygit'
191cat /usr/lib/python2.7/site-packages/easy-install.pth | grep "^./" | cut -c3- | cut -f1 -d- > egg.txt
192    cat egg.txt | xargs easy_install -Z
193
194# - Look at `gem list` for Ruby gems.
195#   Again, use 'yum search' and prefer RPMs, but failing that, 'gem install'.
196#       ezyang: rspec-rails depends on rspec, and will override the Yum
197#       package, so... don't use that RPM yet
198# XXX This doesn't do the right thing for old version gems
199gem list --no-version > gem.txt
200    gem install $(gem list --no-version | grep -Fxvf - gem.txt)
201    # Also, we need to install the old rails version
202    gem install -v=2.3.5 rails
203
204# - Look at `pear list` for Pear fruits (or whatever they're called).
205#   Yet again, 'yum search' for RPMs before resorting to 'pear install'.  Note
206#   that for things in the beta repo, you'll need 'pear install package-beta'.
207#   (you might get complaints about the php_scripts module; ignore them)
208pear list | tail -n +4 | cut -f 1 -d " " > pear.txt
209    pear config-set preferred_state beta
210    pear channel-update pear.php.net
211    pear install $(pear list | tail -n +4 | cut -f 1 -d " " | grep -Fxvf - pear.txt)
212
213# - Look at `pecl list` for PECL things.  'yum search', and if you must,
214#   'pecl install' needed items. If it doesn't work, try 'pear install
215#   pecl/foo' or 'pecl install foo-beta' or those two combined.
216pecl list | tail -n +4 | cut -f 1 -d " " > pecl.txt

329#   - We don't serve the web, so don't bind scripts.mit.edu
330#   - We don't serve LDAP, so use another server
331# This involves editing the following files:
