------------------------------------------------------------------------

0. mango:/home/service/pkgs/
   dpkg -i cvs_1.11.1p1debian-9woody7_i386.deb

1. backup and update umltools
   mango:/home/service/bin
   #> tar -czf umltools_2004-09-21.tar.gz umltools
   #> su joko
   #> ssh-keygen -d
   #> cat ~/.ssh/id_dsa.pub | ssh joko@netfrag.org "cat - >> ~/.ssh/authorized_keys"
   #> cd umltools
   #> cvs -q update -d

2. shutdown quepasa
   quepasa # sync
   quepasa # /etc/init.d/apache stop
   quepasa # killall -9 apache
   quepasa # halt

3. compress disk images of quepasa on h1.service.netfrag.org
   h1 # cd /home/uml/quepasa/rootfs
   h1 # tar -cjf rootfs.tar.bz root_fs.woody-stable.ext3

   h1 # cd ../datafs
   h1 # tar -czf data_fs.tar.gz data_fs.ext3 &
   h1 # tar -czf data2_fs.tar.gz data2_fs.ext3 &

4. copy images to mango:

   root@h1:/home/uml/quepasa/rootfs # 
   #> screen
   #> scp rootfs.tar.bz root@mango.rtme.net:/home/uml/quepasa/rootfs/

   root@h1:/home/uml/quepasa/datafs #
   #> scp data_fs.tar.gz root@mango.rtme.net:/home/uml/quepasa/datafs/
   #> scp data2_fs.tar.gz root@mango.rtme.net:/home/uml/quepasa/datafs/

5. copy kernel to mango:
   root@h1:/usr/bin # scp linux_2.4.18-29 root@mango.rtme.net:/usr/local/bin/

6. while above things are happening, we can configure some other things:
   a) /home/service/etc/UML/Config.pm
   b) /etc/hosts; nothing to do
   c) /etc/resolv.conf
      nameserver 213.133.98.98
      nameserver 213.133.99.99
      nameserver 213.133.100.100
      nameserver 213.133.104.100

7. unpack images on mango

   mango:/home/uml/quepasa/rootfs
   #> tar -xjf rootfs.tar.bz

   mango:/home/uml/quepasa/datafs
   #> tar -xzf data_fs.tar.gz
   #> tar -xzf data2_fs.tar.gz

   set permissions:
   mango:/home/uml
   #> chown -R service.staff quepasa/

8. prepare quepasa

   #> uml_boot --vhost=quepasa --prepare


9. start quepasa
   #> sue service
   #> uml_boot --vhost=quepasa --start
   #> screen -r quepasa

10. last but not least:

   a) grep for the old ip-address: 213.133.125.247
   mango:/home/uml/quepasa/mnt
   #> grep -ri "213.133.125.247" *
   iptables.rules
   hosts:213.133.125.247   quepasa.netfrag.org quepasa
   hosts:213.133.125.247   www.netfrag.org
   hosts:#213.133.125.247  sorceress.netfrag.org
   iptables.rules: #IPADDR="213.133.125.247"
   network/interfaces:        address 213.133.125.247

   b) more apache
   /data/www/global/conf/httpd.conf

   c) install as daemon
   #> cd /home/service/bin/umltools
   #> ./uml_setup.pl --vhost=quepasa --daemonize

   d) resize filesystem
   http://user-mode-linux.sourceforge.net/resize.html

   quepasa # halt   

   mango:/home/uml/quepasa/datafs #
   #> e2fsck -f data_fs.ext3
   #> dd if=/dev/zero of=data_fs.ext3 bs=1 count=1 seek=3G conv=notrunc
   #> resize2fs -p data_fs.ext3

   e) turck-mmcache
      #> apt-get install turck-mmcache
      #> dpkg -i turck-mmcache_2.4.6-8_i386.deb
      #> dpkg --force-all -i turck-mmcache_2.4.6-8_i386.deb
      #> apt-get -f install

   comment out /usr/lib/php4/2002... from /etc/php4/apache/php.ini

Setting up turck-mmcache (2.4.6-8) ...
You are installing Turck-MMCache for php4, but it is not
yet enabled in your /etc/php4/apache/php.ini and/or
/etc/php4/cgi/php.ini files.

To enable it you need to add these lines:

zend_extension="/usr/lib/php4/20020429/mmcache.so"      ; turck-mmcache
mmcache.shm_size="16"                                   ; turck-mmcache
mmcache.cache_dir="/var/cache/turck-mmcache"            ; turck-mmcache
mmcache.enable="1"                                      ; turck-mmcache
mmcache.optimizer="1"                                   ; turck-mmcache
mmcache.check_mtime="1"                                 ; turck-mmcache
mmcache.debug="0"                                       ; turck-mmcache
mmcache.filter=""                                       ; turck-mmcache
mmcache.shm_max="0"                                     ; turck-mmcache
mmcache.shm_ttl="0"                                     ; turck-mmcache
mmcache.shm_prune_period="0"                            ; turck-mmcache
mmcache.shm_only="0"                                    ; turck-mmcache
mmcache.compress="1"                                    ; turck-mmcache

Do you want me to do it for you now? [Y/n]
