1This document is a how-to for installing a Fedora scripts.mit.edu server.
2
3Helper files for the install are located in server/fedora/config.
4
5* Start with a normal install of Fedora.
6
7* Edit /etc/selinux/config so it has SELINUX=disabled and reboot.
8
9* Check out the scripts.mit.edu svn repository. Configure svn not to cache
10  credentials.
11
12* cd to server/fedora in the svn repository.
13
14* Run "make install-deps" to install various prereqs.  Nonstandard
15  deps are in /mit/scripts/rpm.
16
17* Check out the scripts /etc configuration, which is done most easily by
18  $ svn co svn://scripts.mit.edu/server/fedora/config/etc
19  # \cp -a etc /
20
21* Create a scripts-build user account, and set up rpm to build in
22  $HOME by doing a
23  cp config/home/scripts-build/.rpmmacros /home/scripts-build/
24  (If you just use the default setup, it will generate packages
25  in /usr/src/redhat.)
26
27* su scripts-build -
28
29* Make sure that server/fedora (where you currently are) is writable
30  by user scripts-build.
31
32* env NSS_NONLOCAL_IGNORE=1 yum install scripts-base
33
34* Rebuild mit-zephyr on a 32-bit machine, like the one at Joe's home.
35
36* Run "make suexec" and "make install-suexec" to overwrite
37  /usr/sbin/suexec with one that works. The one installed by the
38  newly-built Apache RPM is misconfigured.
39  ... Except Anders claims he fixed this.
40
41* Remember to set NSS_NONLOCAL_IGNORE=1 anytime you're setting up
42  anything, e.g. using yum. Otherwise useradd will query LDAP in a stupid way
43  that makes it hang forever.
44
45* Install and configure bind
46  - env NSS_NONLOCAL_IGNORE=1 yum install bind
47  - chkconfig named on
48  - service named start
49
50* Reload the iptables config to take down the restrictive firewall
51  service iptables restart
52
53* Copy over root's dotfiles from one of the other machines.
54
55* Replace rsyslog with syslog-ng by doing:
56  # rpm -e --nodeps rsyslog
57  # yum install syslog-ng
58
59* Install various dependencies of the scripts system, including syslog-ng,
60  glibc-devel.i386, python-twisted-core, mod_fcgid, nrpe, nagios-plugins-all.
61
62* Disable NetworkManager with chkconfig NetworkManager off. Configure
63  networking on the front end and back end, and the routing table to send
64  traffic over the back end. Make sure that chkconfig reports "network" on, so
65  that the network will still be configured at next boot.
66
67* Fix the openafs /usr/vice/etc <-> /etc/openafs mapping by changing
68   /usr/vice/etc/cacheinfo to contain:
69        /afs:/usr/vice/cache:10000000
70
71* Figure out why Zephyr isn't working. Most recently, it was because there
72  was a 64-bit RPM installed; remove it and install Joe's 32-bit one
73
74* Install the full list of RPMs that users expect to be on the
75  scripts.mit.edu servers.  See server/doc/rpm and
76  server/doc/rpm_snapshot.  (Note that this is only a snapshot, and not
77  all packages may in fact be in use.)
78
79* Install the full list of perl modules that users expect to be on the
80  scripts.mit.edu servers.  See server/doc/perl and
81  server/doc/perl_snapshot.
82
83  - export PERL_MM_USE_DEFAULT=1
84  - Run 'cpan', accept the default configuration, and do 'o conf
85    prerequisites_policy follow'.
86  - Parse the output of perldoc -u perllocal | grep head2 on an existing
87    server, and "notest install" them from the cpan prompt.
88
89* Install the Python eggs and Ruby gems and PEAR/PECL doohickeys that are on
90  the other scripts.mit.edu servers and do not have RPMs.
91  - Look at /usr/lib/python2.5/site-packages for Python eggs and modules.
92  - Look at `gem list` for Ruby gems.
93  - Look at `pear list` for Pear fruits (or whatever they're called).
94
95* echo 'import site, os.path; site.addsitedir(os.path.expanduser("~/lib/python2.5/site-packages"))' > /usr/lib/python2.5/site-packages/00scripts-home.pth
96
97* Install the credentials (machine keytab, daemon.scripts keytab, SSL
98  certs).
99
100* If you are setting up a test server, pay attention to
101  /etc/sysconfig/network-scripts and do not bind scripts' IP address.
102  You will also need to modify /etc/ldap.conf, /etc/nss-ldapd.conf,
103  /etc/openldap/ldap.conf, and /etc/httpd/conf.d/vhost_ldap.conf to
104  use scripts.mit.edu instead of localhost.
105
106* Install fedora-ds-base and set up replication (see ./HOWTO-SETUP-LDAP
107    and ./fedora-ds-enable-ssl-and-kerberos.diff).
108
109* Make the services dirsrv, nslcd, nscd, postfix, and httpd start at
110  boot. Run chkconfig to make sure the set of services to be run is
111  correct.
112
113* Run fmtutil-sys --all, which does something that makes TeX work.
114
115* Ensure that PHP isn't broken:
116  # mkdir /tmp/sessions
117  # chmod 01777 /tmp/sessions
118
119* Reboot the machine to restore a consistent state, in case you
120  changed anything.
121
122* (Optional) Beat your head against a wall.
123
124* Possibly perform other steps that I've neglected to put in this
125  document.
