+Services and applications:
+ mysql
+ monit
+ pcre
+ fcgi
+ lighttpd
+ memcached
+ beanstalkd
+Python packages:
+ These can be installed with pip/easy_install or other means:
+ flup
+ python-memcached
+ simplejson
+ python-yaml
+ python-mysqld OR MySQL-python
+ oauth2
+ # Make sure that boto is the latest version. If on ubuntu ensure that you're not
+ # using the system boto, which is outdated. Remove the apt-installed boto,
+ # and install from pip
+ boto # necessary for AWS / SES / S3
+ python-dateutil # necessary for
+Mysql setup for the first time:
+ mysql -u root -p
+ > create database gam2; grant all on gam2.* to gam@localhost identified by 'gam';
+ > exit
+ mysql -u root -p gam2 < trunk/sql/models.sql
+ mysql -u root -p gam2 < trunk/sql/locations.sql
+ mysql -u root -p gam2 < trunk/sql/data.sql
+Web Server Setup
+Install lighttpd:
+ [package-manager] install lighttpd
+Launch lighttpd:
+ # Create logs folder
+ mkdir -p trunk/logs && chmod -R a+rw trunk/logs
+ mkdir -p run # necessary for the pid file to be stored
+ lighttpd -D -f lighttpd.conf
+AWS configuration:
+ If thumbnails are being mirrored to S3, complete the info in the aws and media sections
+ of the config file accordingly. Otherwise image uploads will be saved to the local volume only.
+DEVELOPMENT RECOMMENDATIONS (not required, but helps)
+Set up virtualenv and virtualenvwrapper so that python libs are easy to version,
+and so you don't have conflicts between different python projects:
+This allows you to do stuff like:
+ workon cbu
+which will switch to the cbu virtual environment.
+The deployment process for CBU uses Fabric:
+ pip install fabric
+It requires that you have at least fabric Fabric==1.2.0:
+ pip freeze | grep -i fabric
+Fabric uses a script and different configuration files. The default script
+filename is, and configuration files are called "rcfile". To
+facilitate this naming convention, all configuration files are rcfile.ENV,
+where ENV is the environment to which to deploy. Eg. rcfile.demo would be
+the configuration set for the 'demo' environment.
+The fabric script is located in the root of the project as of this writing.
+However, this location may change in future, since deployment scripts really
+should be versioned separately from the code project.
+Configuration files are NEVER versioned with the project since they contain
+sensitive information. Configuration files (rcfiles) are versioned in a private
+repository. Please consult with a sysadmin for the location of this repo.
+The deployment host is assumed to have the following:
+ * SSH key (or pem file) to connect to the target environment under the
+ appropriate user contexts. These files are usually in:
+ ~/.ssh/localprojects/*.pem or ~/.ssh/localprojects/id_rsa
+ The actual file is defined in the rcfile, so it can be changed based on
+ user environment.
+ However, it is recommended that all deployment administrators use a
+ standardized structure for storage of these files so as to limit
+ confusion or inconsistency.
+ * A source tree in a standardized location. The git source tree is expected
+ to be at ~/Projects/LP/<project-name>:
+ ~/Projects/LP/lp-changebyus
+ This is also configurable in the RCfile, so can be changed as needed.
+ [NOTE: this really should not be required since the deployer should
+ have a way of pulling the code to a working location and creating the
+ final configurations from it. Unfortunately this functionality is not yet
+ implemented.]
+ * The necessary RCfiles in a separate location. Eg.:
+ ~/Projects/LP/configs/lp-changebyus/rcfile.*
+Once the system is set up, the deployment steps are:
+ fab -f /path/to/ \
+ --config=/path/to/rcfile.XX ENV \
+ <list of tasks>
+ /path/to/ : the path to the or rcfile.env. NOTE that fabric
+ does NOT handle ~ (user-path) correctly, so always specify
+ full path. Relative paths from current location work fine
+ rcfile.XX : The rcfile to use. Ensure that you provide the /path/to/
+ correctly. If you receive an error such as:
+ "AttributeError: local_path"
+ this is indication that your rcfile was not read correctly.
+ Check your paths!
+ ENV : The environment that the configuration is specific to. This
+ is actually a task which processes all the system and
+ required variables, and is usually one of live, prod, demo, dev.
+Deployment TASKS:
+The tasks for deployment are generally found at the top of the file,
+in the CookBook section. To get detailed information about the function of each
+available task, run:
+ fab --list
+Some of the more common sets of tasks are below.
+* Create all the configurations locally, for development purposes:
+ fab --config=/path/to/rcfile.developer-name dev \
+ create_local_configs
+ This will manufacture the config files for you to be able to run the system on your
+ local environment, assuming that your local web server points to your source folder.
+* Standard deployment of branch defined in rcfile, with webserver restart:
+ fab --config=/path/to/rcfile.demo demo \
+ bundle_code deploy_webapp deploy_configurations
+* Only deploy configuration updates, but not new code
+ fab --config=/path/to/rcfile.demo demo \
+ deploy_configurations
+* Deploy the latest code, change the 'current' symlink, but don't restart
+ webserver. This is useful if you want to just put code up, but don't want
+ the webserver to know about it yet.
+ fab --config=/path/to/rcfile.demo demo \
+ bundle_code deploy_app
+ You can then run the
+ fab --config=/path/to/rcfile.demo demo \
+ restart_webserver
+ task to ... um ... restart the webserver.
+* Deploy the latest code, but don't symlink, and don't do anything else:
+ fab --config=/path/to/rcfile.demo demo \
+ bundle_code upload_and_explode_code_bundle
+* Rollback the deploment (NOT YET TESTED):
+ fab --config=/path/to/rcfile.demo demo \
+ rollback
+ This will:
+ mv current next
+ mv previous current
+Troubleshooting and Debugging Notes
+ On server startup:
+ boto.exception.NoAuthHandlerFound: No handler was ready to authenticate. 1 handlers were checked. ['HmacAuthV3Handler'] Check your credentials
+ This is invariably due to an AWS configuration issue. Either the key or the secret are wrong, or
+ incorrectly configured in the config file.
+ easy_install pip
+ pip install virtualenvwrapper
+ mkvirtualenv cbu
+ pip -E cbu install --use-mirrors <packages>
