 ====== Checklist for upgrading production servers to 2.8 ====== ====== Checklist for upgrading production servers to 2.8 ======
  
-Sites to be upgraded on damocles.met.no: +See [[https://dokit.met.no/prosjekter/metsis/damocles_upgrade]]
- +
-  * damocles (owns damocles_metadata and damocles_userbase) +
-  * dokipy +
-  * ipycoord +
-  * gcwdemo  +
- +
-Other sites: +
- +
-  * arcticdata (separate server) +
- +
-===== Phase 1. Preparation ===== +
- +
-Using gcwdemo as an example in code. +
- +
-==== Server configuration ==== +
- +
-  sudo apt-get install metno-perl-webdev-ver1 +
- +
-==== Site configuration ==== +
- +
-This should ideally be setup via https://svn.met.no/projects/metamodapps/, but will take too long to figure out. Instead will use existing generated master_config as starting point and backmerge changes to svn later. Custom styles ignored at this point - must be added later. +
- +
-Must be repeated for each site.  +
- +
-=== base directory === +
- +
-To avoid complications with existing instances, put the new sites in ''/metno/metamod/metamod28/*'' (the old sites are in ''/metno/metamod/*''). This means webrun will not be corrupted by mixing old and new data. +
- +
-=== master_config === +
- +
-  cd /metno/metamod/metamod28/gcwdemo +
-  sudo -u damocles mkdir app +
-  sudo -u damocles cp /metno/metamod/gcwdemo/r1/master_config.txt app/ +
- +
-Compare old master_config to default: +
- +
-  cd .. +
-  trunk/common/scripts/chk_conf.pl trunk/app/example/master_config.txt \ +
-    gcwdemo/master_config.txt  +
- +
- +
-=== Other custom files === +
- +
-Postponed until Phase 5 +
- +
-==== Metamod source ==== +
- +
-  cd /metno/metamod/metamod28 +
-  sudo svn co https://svn.met.no/metamod/trunk +
-  sudo chown -R damocles.damocles trunk/ # needed for building +
- +
-===== Phase 2. Setting up new database ===== +
- +
-Only done once.  +
- +
-Database setup requires scripts generated to target. This means the Generate Target part of Phase 3 for site damocles must be executed first. +
- +
-The database is not on the damocles server, but on **metamoddb.met.no**. This contains among others the following databases: +
- +
-^Name                  ^ Owner    ^ +
-|damocles_metadata     | admin    | +
-|damocles_userbase     | admin    | +
- +
-To avoid conflicts and downtime, make two new databases for 2.8 instead: +
- +
-==== damocles28_userbase ==== +
- +
-  * userdb data are not duplicated anywhere else +
-    * must dump 2.6 userdb and import into 2.8, then run upgradeuserdb_26-28.sh +
-    * see http://www.postgresql.org/docs/8.3/static/backup.html#BACKUP-DUMP +
- +
-  pg_dump -h metamoddb -U admin damocles_userbase > damocles_userbase.sql  +
-   +
- +
-==== damocles28_metadata ==== +
- +
-  * metadatadb must probably be generated from scratch using createdb.sh? +
-  * which xml files should be used to populate the DB? +
-    * /metno/metamod/damocles/webrun/XML/DAMOC ? (see damocles/master_config) +
-    * run import_dataset.pl on files +
-      * anything else to think of? (if so, probably best Heiko did this) +
- +
-===== Phase 3. Setting up generic metamod ===== +
- +
-This will setup a generic Metamod 2.8 instance to test the system is running. Customization will be done afterwards, and the installation re-run. +
- +
-Must be repeated for each site.  +
- +
-==== Generate target ==== +
- +
-  cd /metno/metamod/metamod28/gcwdemo +
-  sudo -u damocles PERL5LIB=/opt/metno-perl-webdev-ver1/lib/perl5 ../trunk/update_target.pl app/ +
-   +
-Note that Calalyst building tests during update_target will fail unless you have a working, up-to-date database; also, you cannot upgrade your database without running update_target. Chicken, meet egg. Suggest temporary commenting out the following on line 237 (+/-): +
- +
-  # +
-  # install Catalyst files before $appdir to avoid clobbering custom files +
-  # +
-  &install_catalyst; +
- +
-You will now get the following error message: +
- +
-  Configuring application '' with Metamod 2.8 (2.8.0) +
-  Cannot write to target dir /metno/metamod/metamod28/damocles/target at ../trunk/update_target.pl line 189. +
- +
-Time to take the weekend off and try again next week. +
- +
-Create/update the runtime-environment: +
- +
-  sudo -u damocles ./prepare_runtime_env.sh +
- +
-==== Test Catalyst ==== +
- +
-Remember each site must have its own dedicated port: +
- +
-|damocles|3000| +
-|dokipy|3001| +
-|ipycoord|3002| +
-|gcwdemo|3003| +
- +
- +
-==== Apache configuration ==== +
- +
-This server uses DNS-based virtual hosting, however each site already has an existing +
-setup in sites-available. This means the generated httpd.conf in target/etc cannot be used directly; instead you must manually copy & paste the new config into the old file. +
-(Perhaps later when the 2.6 versions are turned off we could use the generated config files directly.) +
- +
-==== Install services ==== +
- +
-Do not run install_jobs.sh; instead install links manually. +
- +
- +
- +
-===== Phase 4. Adding custom functions and styling ===== +
- +
-Todo by someone else (have no idea what is required and how to implement it). +
- +
-Must be repeated for each site.  +
- +
