Simple cerbrum/bofhd setup

TODO: Out of date, use scripts/jointconfig instead. (nov 2013)

Alexander Rødseth for USIT, June 2013

TODO: Update with the information from July 2013 in tools.rst

Step by step

Log in to cere-utv01.uio.no
Checkout cerebrum to ~/checkout/cerebrum
Create a directory for the configuration files and local scripts:
```
mkdir -p ~/checkout/cerebrum/{conf,bin}
```

Create ~/checkout/cerebrum/conf/config.dat:

# Config file for bofhd
Cerebrum.modules.no.uio.bofhd_uio_cmds/BofhdExtension
Cerebrum.modules.no.uio.bofhd_guestaccounts_cmds/BofhdExtension
#Cerebrum.modules.no.uio.printer_quota.bofhd_pq_cmds/BofhdExtension
Cerebrum.modules.no.uio.bofhd_ephorte_cmds/BofhdExtension
#Cerebrum.modules.dns.bofhd_dns_cmds/BofhdExtension
#Cerebrum.modules.dns.Subnet/BofhdExtension

Create ~/checkout/conf/cereconf.py:

execfile(os.path.expanduser("/cerebrum/uio/etc/cerebrum/cereconf.py"))
CEREBRUM_DATABASE_CONNECT_DATA['user'] = "cerebrum"
CEREBRUM_DATABASE_CONNECT_DATA['host'] = "dbpg-cere-utv.uio.no"
CEREBRUM_DATABASE_NAME = "cerebrum_uio_rw"

Create one empty configuration file:

touch ~/checkout/cerebrum/conf/cereconf_dns.py

Use Robert's cerebrum_path.py, put it in ~/checkout/cerebrum/conf:

# -*- coding: utf-8 -*-

import inspect as _inspect
import os as _os
import sys as _sys
import pwd as _pwd

_commonprefix = "/cerebrum"

_instances = {
        'uio': '%s/uio/' % _commonprefix,
        'uia': '%s/uia/' % _commonprefix,
        'gisk': '%s/giske/' % _commonprefix,
        'nih': '%s/nih/' % _commonprefix,
        'ofk': '%s/ofk/' % _commonprefix,
        'nmh': '%s/nmh/' % _commonprefix,
        'hiof': '%s/hiof/' % _commonprefix,
        'hih': '%s/hih/' % _commonprefix,
        'web': '%s/webid/' % _commonprefix,
        }

#try:
#    _prefix = _instances[_pwd.getpwuid(_os.getuid())[0]]
#except KeyError:
#    assert False, "Unknown user %s, check %s\n" % (_os.getlogin(), __file__)

_prefix = _instances[_os.environ.get('CEREBRUM_INST') or 'uio']

_sys.path.append(_os.path.join(_prefix, 'etc', 'cerebrum'))
_sys.path.append(_os.path.join(_prefix, 'lib', 'python2.5', 'site-packages'))

_f = _inspect.currentframe()
while _f.f_back:
    _f = _f.f_back

try:
    _fn = _f.f_globals['__file__']
except KeyError:
    _sys.stderr.write("Running session from command line\n")
else:
    pass
    #_fn = _os.path.realpath(_fn)

    #if _fn.startswith(_commonprefix):
    #    assert _fn.startswith(_prefix), "Not allowed to run %s as %s\n" % (_fn,
    #            _pwd.getpwuid(_os.getuid())[0])

    #for _i in map(_os.path.realpath, _sys.path):
    #    if _i.startswith(_commonprefix):
    #        assert _i.startswith(_prefix), "%s not allowed in PYTHONPATH\n" % _i

Set a new PATH and PYTHONPATH by putting this in your ~/.zshrc or ~/.bashrc file:

if [ `hostname` = 'cere-utv01.uio.no' ]; then
  echo -n 'Development environment...'
  export PYTHONPATH=~/checkout/cerebrum/conf:~/checkout/cerebrum:/site/lib/python2.5/site-packages
  export PATH=/local/bin:$PATH
  echo 'ok'
fi

Logg off and on again or just run $SHELL

Put this in ~/checkout/cerebrum/bin/bofhd.sh (select your own port number):

#!/bin/sh
python ~/checkout/cerebrum/servers/bofhd/bofhd.py \
  -c ~/checkout/cerebrum/conf/config.dat \
  --logger-name=console \
  --logger-level=DEBUG \
  --port 1337

And this in ~/checkout/cerebrum/bin/bofh.sh (use the port number you just selected):

#!/bin/sh
bofh --url https://cere-utv01.uio.no:1337 \
  --set "console_prompt=test_uio_bofh> "

Make the scripts executable:
```
chmod +x ~/checkout/cerebrum/bin/*
```
Run bofhd and bofh in tmux (if tmux is not available, use screen instead):
```
cd ~/checkout/cerebrum
tmux
bin/bofhd.sh
```
Press ctrl-b, c, then type (for screen, use ctrl-a, c):
```
bin/bofh.sh
```
Done!

Local installations

Install mx:
```
sudo yum install mx
