Setting up GeoNode 2 on 12.04 VM on CedeusGeoNode

>> return to Cedeus_Technical_Architecture

---

basic steps performed

• create a new VM with Ubuntu 12.04 - with openssh and mail installed
• remove the cl locale of /etc/apt/sources.list
• update and upgrade => important because of hardbleed bug
• shutdown + remove the iso from the VM
• copied the VM => basicUbuntu1204.zip

setting up GeoNode

• a listing of necessary packages is here: http://docs.geonode.org/en/master/tutorials/admin/install/custom_install.html#custom-install
• so we need to install
  • (i) apache2,
  • (ii) Java + Tomcat7,
  • (iii) postgresql (postgis only if we want to store the geodata locally),
  • (iv) python stuff for django
• install apache2 sudo apt-get install apache2
• install tomcat7 sudo apt-get install tomcat7
• install python sudo apt-get install python-software-properties
• to install postgresql is not really necessary, as postgres 9.1 will be also installed by geonode, and I am using for my data an external postgresql-postgis db. However, I want 9.3 so:

  see here about adding the repo: http://www.postgresql.org/download/linux/ubuntu/

  sudo apt-get update

  sudo apt-get install postgresql-9.3 pgadmin3 postgresql-contrib

  perform: sudo -u postgres psql and then CREATE EXTENSION adminpack;

  => note, after installing my postgresql 9.3 will be accessed via port 5432

  for doc see also: http://docs.geonode.org/en/master/tutorials/admin/install/install_postgresql.html#install-postgresql

• install GeoNode:

  add the geonode repo key: sudo add-apt-repository ppa:geonode/release

  update the package list: sudo apt-get update

  install geonode:sudo apt-get install genode NB:this wil also install postgres9.1!

  sudo geonode-updateip 127.0.0.1

  geonode createsuperuser

  modify setting in /etc/geonode/local_settings.py and restart apache

  => now the geonode webpage should be running!

  Btw. the psotgres 9.1 version installed together with geonode will be accessed via port 5433, while 5432 is used by 9.3 already

modify GeoNode styling

• change webpage colors and add cedeus logo

  • create folders /etc/geonode/media/geonode/img/ and /etc/geonode/media/geonode/css/

    copy cedeus logo.png and cedeus base.css into its corresponding folder (may require chmod 777)

    perform sudo geonode collectstatic -v0

    => check if it worked

• change welcome text for es/en/de

  change django.po files for each language in /usr/local/lib/python2.7/dist-packages/geonode/locale (for german file, check around line 3600) (may require switch of chmod 777 from originally 755)

  run sudo geonode compilemessages -l de from "/usr/local/lib/python2.7/dist-packages/geonode/" for each particular language

  • => check if it worked

fine tuning for working with Geonode

see also http://docs.geonode.org/en/latest/tutorials/admin/production.html

• direct access to the db with PgAdmin:
  • modify /etc/postgresql/9.3/main/postgresql.conf and /etc/postgresql/9.3/main/pg_hba.conf (for pq_hba.conf see http://www.glom.org/wiki/index.php?title=Initial_Postgres_Configuration)

  => be sure to edit the right postgres files with respect to the installed postres versions

  • sudo service postgresql restart
  • check if connection with pgAdmin to geonode db works (which contains user and metadata)
• set the memory for tomcat7: create file /usr/share/tomcat7/bin/setenv.sh and add the following lines

#!/bin/sh 
JAVA_OPTS="-Xms512m -Xmx4g -XX:MaxPermSize=270m -server -Djava.awt.headless=true -Djava.util.prefs.systemRoot=$CATALINA_HOME/content/thredds/javaUtilPrefs" 
export JAVA_OPTS

• disallow user self registration - Note, does not seem necessary. Default seems to be "False".
  • add to /etc/geonode/local_settings.py the line REGISTRATION_OPEN=True for enabling registration to all
• create users and user groups
  • use the admin option from within geonode, which links to the django admin pages
  • eg. I created two user groups cedeusadmin and cedeususer with user stefanS (1...a) as member of the latter group, and stefanadmin(20..s) as "staff member" a default group. also I created a "cedeus_testuser" (fo...p2...3)
• adjust geoserver settings as described under http://docs.geonode.org/en/latest/tutorials/admin/production.html
  • add proxy address under global settings
  • change admin pw, plus create "cedeus" user for backup resasons (pw same as for external postgisdb)
  • add host IP for printing to /usr/share/geoserver/data/printing/config.yaml
• create /robots.txt file in var/www/ (for conent see link above)
• modify /etc/tomcat7/server.xml by adding maxThreads="50" to connector 8080 settings.
• GeoServer > JAI settings: disable Tile Recycling and enable jpg and png acceleration
