This is unalog2. It's a from-scratch rewrite of the original unalog social bookmarking application. It was written by Dan Chudnov (dchud at umich edu) who also wrote the original application starting in 2003. The original application was a Python app that used Quixote1, ZODB, and PyLucene. This is a Python app that uses Django, PostgreSQL, and Solr. This app can be fed by a JSON export from the original application; that's how the main site at unalog.com was refed when the site was restarted in early 2010. The site broke in late 2008 due to some negligence and general performance problems. It had been "out there" on the net for five years without a lot of upkeep, which isn't so bad, I suppose. The site was down for all of 2009 because the rewrite got stalled. Stuff happens. unalog2 is licensed under an MIT-style license; see LICENSE.txt. REQUIREMENTS ------------ These are the versions of dependencies used for development and deployment at unalog.com. Python 2.5.2 Django 1.2.4 PostgreSQL 8.3 psycopg2 2.0.13 Java 6 Solr 1.3 solrpy 0.9 simplejson 2.0.9 Last I heard Django will move to Python 3 slowly so I'm going to move to Python 3 slowly, too. When they go, I'll go. INSTALLATION/DEPLOYMENT ----------------------- This is designed to work well under common low-to-middle level VPS or dedicated hosting. I run it with apache2 and mod_wsgi on ubuntu 8.04. Install ubuntu packages (and dependencies) for: python ipython python-setuptools python-simplejson python-feedparser postgresql-8.3 postgresql-client-8.3 python-psycopg2 sun-java6-jdk solr-tomcat5.5 libapache2-mod-wsgi The solr-tomcat5.5 package might try to bring in openjdk. That might work but I've only tested with sun-java6-jdk. Use update-java-alternatives to ensure the right jre is used. Set the default encoding of your python installation to 'utf8'. I don't know the 100% "right" way to do this these days, but in my ubuntu/osx python 2.5 and 2.6 setups, I end up putting something like this: import sys sys.setdefaultencoding('utf8') ...into /usr/lib/python2.5/sitecustomize.py at the bottom. You'll know it's right when you can do this and get 'utf8': % python Python 2.5.2 (r252:60911, Jan 20 2010, 21:48:48) [GCC 4.2.4 (Ubuntu 4.2.4-1ubuntu3)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> sys.getdefaultencoding() 'utf8' Install non-.deb python dependencies: from tarball: Django 1.2.4 w/easy_install: solrpy 0.9 (and iso8601, if import from zodb install) Set up solr config. Move the original /etc/solr/conf/schema.xml aside and copy $UNALOG/base/schema.xml to /etc/solr/conf/schema.xml. Note that tomcat is probably running on port 8180; check in /etc/tomcat5.5/server.xml. This port should *never* be visible outside of localhost. The default solr schema is used when solr is first started up with tomcat. Because unalog has a different schema, we need to stop solr, remove the tiny index solr created at startup with the old schema, and restart tomcat. Solr will then restart and create a new index based on our schema. % sudo /etc/init.d/tomcat5.5 stop % sudo rmdir /var/lib/solr/data/index % sudo /etc/init.d/tomcat5.5 start Set up postgresql config. Username below just a sample, pick your own. Create a user: % sudo su postgres % createuser --createdb --pwprompt unalog2user05 # pick your own (set the pass. remember it. :) % exit As yourself/sudoing: - adjust /etc/postgresql/8.3/main/pg_hba.conf appropriately - restart postgres if needed. % createdb unalog2db05 # pick your own name Set up unalog config. Examine settings.py for the defaults. The last thing this file does is look for a "local_settings.py" file. This is where you'll put your own local settings. Create a file called "local_settings.py" in the same directory as settings.py. In that file, set at least the following: Set the following at least: - ADMINS - REALM # should be unique to your site/instance - UNALOG_URL # e.g. 'http://localhost:8000', leaving off trailing slash - SECRET_KEY - DATABASE_NAME - DATABASE_USER - DATABASE_PASSWORD - TEMPLATE_DIRS - SOLR_URL # e.g. 'http://localhost:8180/solr', depending on tomcat conf Prep the db schema: % python manage.py syncdb (this should create a lot of tables. create a superuser.) Run the app just to see if it works: % python manage.py runserver (visit http://localhost:8000/ or wherever the dev server starts) You should be able to see unalog up and running. Finally, to quickly test the whole system: - log in as the superuser you created - visit the /bookmarklet/ path (link is in header) - put a bookmarklet in your browser bookmarks bar - visit some random web page - click the 'unalog!' bookmarklet in your browser bookmarks bar - add some tags or a comment - click 'Home'. do you see your entry? - search for your entry (use a title word or a tag). do you see your entry? - if the answer to the last two questions was 'yes', you're up and running! For apache2+mod_wsgi deployments: Add the content of $UNALOG2/base/apache.conf to an appropriate /etc/apache2/sites-available. Be sure to set the root path in all the obvious places. Be sure this config will align with what you set UNALOG_URL to in unalog2's settings.py. Set the local path to the parent of the unalog2 dir inside of $UNALOG2/base/apache.wsgi. Restart apache2 and visit your site.
