[[Help|Ask for help]] right away if you run into problems. || <<Anchor(system)>> = System Requirements = '''Building and running Launchpad requires a computer running [[http://www.ubuntu.com/|Ubuntu]]. The production Launchpad.net site runs on Ubuntu 16.04 LTS. Developers mostly run 16.04 LTS, but others may work.''' The recommended development configuration is Ubuntu 16.04 LTS or later running Launchpad [[Running/LXD|in an Ubuntu 16.04 LTS LXD container]] to minimise its impact on the wider system. Parts of Launchpad assume at least Python 2.7.9 (i.e. newer than Ubuntu 14.04 LTS). If you're not running a supported Ubuntu release you might choose to use an LXC/LXD container or virtual machine with an installation of one of these Ubuntu releases. We'd like Launchpad to run on other operating systems, especially [[http://www.debian.org/|Debian GNU/Linux]], so that more people can contribute to Launchpad development. If you're interested in working on Launchpad portability, please [[https://dev.launchpad.net/Help|let us know]]. Note that our focus is on getting Launchpad to build easily so more people can participate in Launchpad development. Running a stable production instance would be ''much'' harder than running a single-developer test instance, and we don't recommend it. Unlike many open source projects, we're not seeking to maximize the number of installations; our goal is to improve the instance we're already running at Launchpad.net. '''''Note:''' the changes introduced by the install script may break your current web development setup, so it is advisable to try Launchpad in an LXC/LXD container or a virtual machine, as described above.'' = Getting = If you're using an LXC/LXD container or a virtual machine, make sure you're performing all these steps inside it. If your Launchpad username differs from your local one, then put this in `~/.ssh/config` in the container/VM before doing anything else, replacing `LPUSERNAME` with your Launchpad username: {{{ Host bazaar.launchpad.net User LPUSERNAME Host git.launchpad.net User LPUSERNAME }}} {{{ $ mkdir ~/launchpad $ cd ~/launchpad $ bzr --no-plugins cat http://bazaar.launchpad.net/~launchpad-pqm/launchpad/devel/utilities/rocketfuel-setup > rocketfuel-setup $ chmod a+x rocketfuel-setup $ ./rocketfuel-setup ## This will take a while -- maybe a few hours to get everything, ## depending on your Internet connection. ## ## Note that you will be prompted for your 'sudo' password, and for ## a Launchpad login ID. The sudo access is necessary to get ## Launchpad running on your box; the Launchpad.net login is not ## strictly necessary, and you can just hit Return there if you ## want; see below for an explanation. ## ## Note that this will make changes to your Apache configuration if ## you already have an Apache server on your box. It will also add ## entries to /etc/hosts and it will setup a postgresql server on ## your box. ## If you want to play safe with regards to your existing Apache, ## try this out in a virtual environment first. ## ## If you are running rocketfuel-setup to bring up a new machine ## you can pass --no-workspace to only perform the system-wide setup. ## ## Note that if rocketfuel-setup bails out with instructions to fix ## something you just need to run it again and it should pickup where ## it left off. $ sudo apt-get dist-upgrade ## This is just to make doubly-sure everything from the launchpad PPA ## gets installed. $ ls lp-branches/ lp-sourcedeps/ $ cd lp-branches ## You are now in a newly-created Bazaar repository, with one ## branch ('devel'), into whose working tree the other ## source dependencies have been symlinked. The sourcedeps ## actually live in ../lp-sourcedeps, though. }}} <<Anchor(build)>> = Building = First, be in the top level of the source tree: {{{ $ cd devel }}} Before you can run Launchpad for the first time, you need to set up PostgreSQL. ||<tablestyle="width: 100%;" colspan=3 style="background: #ff0000; font-weight: bold; color: #fff;">WARNING!||'''DO NOT run the database setup script below if you use PostgreSQL for anything other than Launchpad!''' Running the script will destroy any PostgreSQL databases on your system. See [[DatabaseSetup]] for details.|| {{{ $ ./utilities/launchpad-database-setup $USER }}} ''(Please have read the previous comment before you run the above command!)'' Finally, build the database schema: {{{ $ make schema }}} <<Anchor(start)>> = Running = Now you should be able to start up Launchpad: {{{ $ make run }}} This only runs the basic web application. [[Code/HowToUseCodehostingLocally|Codehosting]] and [[Soyuz/HowToUseSoyuzLocally|Soyuz]] require additional steps. For subsequent builds, you can just do `make run` right away. You don't need to do `make schema` every time, and you should avoid it because it's expensive and because it will clean out any data you might have put into your test instance (through the web UI or by running other scripts). Point your usual web browser at `https://launchpad.test`, and accept the local self-signed certificate. You can log in as `admin@canonical.com` without a password. <<Anchor(stop)>> = Stopping = You can stop Launchpad by hitting '''Control-C''' in the terminal where you started it: {{{ ^C [...shutting down Launchpad...] $ }}} Or you can be at a prompt in the same directory and run this: {{{ $ make stop }}} = Subpage Index = * [[/RemoteAccess]] -> How to set things up so you can use it from another host. = Details = == What the Installation Process Does == The '''`rocketfuel-setup`''' script first determines what release of Ubuntu you're running, then installs various lines into files under '''`/etc`''', to enable you to run Launchpad services locally. For example, it adds entries for "launchpad.test", "bazaar.launchpad.test", "lists.launchpad.test", and others to your '''`/etc/hosts`''' file, so that after you build launchpad you can browse to '''`launchpad.test`''' and see a locally-running instance. It also installs some packages, dependencies that Launchpad needs in order to run. This is why the sudo access is necessary; consult the script for details of what it's doing. Once it's got the system preparation out of the way, the script initializes a Bazaar repository (that's the '''`lp-branches`''' directory above), and pulls down a development trunk ('''`lp-branches/devel`'''). That will take a while. After it gets that, it fetches the other dependencies, the third-party libraries, by invoking a separate script, '''`lp-branches/devel/utilities/rocketfuel-get`'''. That will take a while too, as there are almost thirty such libraries. Once it has all the dependencies, it links them into the trunk working tree, using the script '''`lp-branches/devel/utilities/link-external-sourcecode`'''. == Do-it-yourself installation == '''We only support using `rocketfuel-setup` to set up Launchpad.''' It adjusts a lot of things to get the development process running smoothly, as summarized above. However, sometimes you might want to just get a build of Launchpad to run its tests, or to run a script packaged with Launchpad, or to do your own manual changes of the files that '''`rocketfuel-setup`''' would normally touch. These are the basics of what needs to be done for that route -- '''unsupported hints'''. === Install launchpad-developer-dependencies === You'll need packages from a PPA: `ppa:launchpad/ppa`. {{{ sudo apt-add-repository ppa:launchpad/ppa }}} Then install the `launchpad-developer-dependencies` package. === Get the code === {{{ bzr branch lp:launchpad cd launchpad utilities/update-sourcecode bzr co --lightweight lp:lp-source-dependencies download-cache mkdir eggs make }}} |
