Available tasks --------------- after_update_code Perform any post code deployment tasks e.g.Copy production version of database.yml after_update_current Perform any post code deployment tasks e.g.Copy production version of database.yml capserverext_usage Usage of prepare host task: cleanup Removes unused releases from the releases directory. By default, the last 5 releases are retained, but this can be configured with the 'keep_releases' variable. This will use sudo to do the delete by default, but you can specify that run should be used by setting the :use_sudo variable to false. cold_deploy Used only for deploying when the spinner isn't running. It invokes 'update', and when it finishes it then invokes the spinner task (to start the spinner). compile_nginx downloads, configures, compiles and installs latest nginx version configure_apache Configure Apache. This uses the :use_sudo variable to determine whether to use sudo or not. By default, :use_sudo is set to true. configure_mongrel_cluster Configure Mongrel processes on the app server. This uses the :use_sudo variable to determine whether to use sudo or not. By default, :use_sudo is set to true. configure_nginx Configure Nginx. Depends on setup_nginx and setup tasks. This uses the :use_sudo variable to determine whether to use sudo or not. By default, :use_sudo is set to true. deploy A macro-task that updates the code, fixes the symlink, and restarts the application servers. deploy_with_migrations Similar to deploy, but it runs the migrate task on the new release before updating the symlink. (Note that the update in this case it is not atomic, and transactions are not used, because migrations are not guaranteed to be reversible.) deprec_setup Set up the expected application directory structure on all boxes diff_from_last_deploy Displays the diff between HEAD and what was last deployed. (Not available with all SCM's.) disable_cdrom_install disable cdrom as a source of packages disable_multiverse disable universe repositories disable_universe disable universe repositories disable_web Disable the web server by writing a "maintenance.html" file to the web servers. The servers must be configured to detect the presence of this file, and if it is present, always display it instead of performing the request. enable_multiverse enable multiverse repositories enable_universe enable universe repositories enable_web Re-enable the web server by deleting any "maintenance.html" file. execute_mysql Execute MySQL statements using --execute option. Set the 'sql' variable. execute_postgres Execute PostgreSQL statements using --command option. Set the 'sql' variable. import_svn Import code into svn repository. install_apache install_gems install_image_magic installs image magick packages install_mongrel_start_script Install start script on the app server install_nginx installs nginx on a ubuntu box install_nginx_prequisites installs nginx compile prerequisites on a ubuntu box install_nginx_start_script Install init script on the web server install_packages_for_rails installs packages required for a rails box install_packages_for_rails_mysql installs packages required for a rails box with mysql install_packages_for_rails_postgres installs packages required for a rails box with postgres install_postfix install postfix and dependent packages install_rails_stack setup_rails_host takes a stock standard ubuntu 'dapper' 6.06.1 server and installs everything needed to be a rails machine install_rails_stack_apache_mysql Takes a stock standard ubuntu 'dapper' 6.06.1 server and installs everything needed to be a rails machine with apache and mysql db install_rails_stack_apache_postgres Takes a stock standard ubuntu 'dapper' 6.06.1 server and installs everything needed to be a rails machine with apache and postgres db install_rails_stack_nginx_mysql Takes a stock standard ubuntu 'dapper' 6.06.1 server and installs everything needed to be a rails machine with nginx and mysql db install_rails_stack_nginx_postgres Takes a stock standard ubuntu 'dapper' 6.06.1 server and installs everything needed to be a rails machine with nginx and postgres db install_rmagick install the rmagic gem, and dependent image-magick library install_rubygems invoke A simple task for performing one-off commands that may not require a full task to be written for them. Simply specify the command to execute via the COMMAND environment variable. To execute the command only on certain roles, specify the ROLES environment variable as a comma-delimited list of role names. Lastly, if you want to execute the command via sudo, specify a non-empty value for the SUDO environment variable. migrate Run the migrate rake task. By default, it runs this in the version of the app indicated by the 'current' symlink. (This means you should not invoke this task until the symlink has been updated to the most recent version.) However, you can specify a different release via the migrate_target variable, which must be one of "current" (for the default behavior), or "latest" (for the latest release to be deployed with the update_code task). You can also specify additional environment variables to pass to rake via the migrate_env variable. Finally, you can specify the full path to the rake executable by setting the rake variable. nginx_postgres_rails_setup Set up the expected application directory structure on all boxes prepare_host prepare_host takes a stock standard ubuntu 'dapper' 6.06.1 server and installs, compiles, configures everything needed to be a rails machine. The combination of web server and database is given by the ':deprec_combination' variable (default: nginx_postgres) prepare_ssh Sets up future ssh connections through a non-standard port given by ssh_security_port (default: 8888) reload_apache Reload Apache reload_nginx Reload Nginx restart Restart the Mongrel processes on the app server by calling restart_mongrel_cluster. restart_apache Restart Apache restart_app Restart application server. restart_mongrel_cluster Restart the Mongrel processes on the app server by starting and stopping the cluster. This uses the :use_sudo variable to determine whether to use sudo or not. By default, :use_sudo is set to true. restart_nginx Restart Nginx rollback A macro-task that rolls back the code and restarts the application servers. rollback_code Rollback the latest checked-out version to the previous one by fixing the symlinks and deleting the current release from all servers. set_permissions Sets group permissions on checkout. Useful for team environments, bad on shared hosts. Override this task if you're on a shared host. setup Set up the expected application directory structure on all boxes setup_admin_account setup_admin_account_as_root setup_apache setup_apache_mysql_servers setup and configure servers for apache and mysql setup_apache_postgres_servers setup and configure servers for apache and postgres setup_app Setup application server. setup_db Setup database server. setup_mongrel_cluster_path setup mongrel_cluster paths setup_mysql Create MySQL database and user based on config/database.yml setup_nginx Sets up required directories for nginx configuration setup_nginx_mysql_servers setup and configure servers for nginx and mysql setup_nginx_postgres_servers setup and configure servers for nginx and postgres setup_paths setup extra paths required for deployment setup_postgres Create PostgreSQL database and user based on config/database.yml setup_postgres_db Setup postgres database server. setup_scm Setup source control server. setup_servers setup and configure servers setup_smtp_server install and configure postfix setup_ssh_keys Copies contents of ssh public keys into authorized_keys file setup_ssh_keys_for_admin_user Copies contents of ssh public keys into authorized_keys file setup_svn Setup svn repository setup_symlinks Setup public symlink directories setup_user_account Sets up a unix user admin account. Gives full sudoer privileges to this user. This will be the current deployment user. setup_user_perms create deployment group and add current user to it setup_web Setup web server. setup_web_for_nginx Setup nginx web server. shell Begin an interactive Capistrano session. This gives you an interactive terminal from which to execute tasks and commands on all of your servers. (This is still an experimental feature, and is subject to change without notice!) show_tasks Enumerate and describe every available task. spinner Start the processes on the application server by calling start_app. start_apache Start Apache start_app Start application server. start_mongrel_cluster Start Mongrel processes on the app server. This uses the :use_sudo variable to determine whether to use sudo or not. By default, :use_sudo is set to true. start_nginx Start Nginx stop_apache Stop Apache stop_mongrel_cluster Stop the Mongrel processes on the app server. This uses the :use_sudo variable to determine whether to use sudo or not. By default, :use_sudo is set to true. stop_nginx Stop Nginx svn_cache_credentials Cache svn name and password on the server. Useful for http-based repositories. svn_remove_log_and_tmp remove and ignore log files and tmp from subversion symlink Update the 'current' symlink to point to the latest version of the application's code. symlink_public Link up any public directories. update Updates the code and fixes the symlink under a transaction update_code Update all servers with the latest release of the source code. All this does is do a checkout (as defined by the selected scm module). update_current Update the currently released version of the software directly via an SCM update operation uptime Display the current uptime and load for all servers, nicely formatted with columns all lined up for easy scanning. watch_load Watch the load on the servers. Display is updated every 30 seconds by default, though you can specify a DELAY environment variable to make it update more or less frequently. watch_requests Watch the number of requests/sec being logged on the application servers. By default, the "production.log" is watched, but if your log is named something else, you can specify it in the log_name variable.
