:orphan: Installation on Linux ===================== We provide Docker containers for Crossbar.io, which we suggest as the easiest way of getting started. If you don't want to use this option, then here's how to install Crossbar.io from sources on any generic Linux. This is a reliable, quick way of installation that does not require superuser rights, can install to any location (such as your home directory) and does not depend on system Python packages. Note: This recipe was tested on a completely fresh install of `Ubuntu `__ `14.04 LTS 64-bit Server `__ running as a `Oracle VirtualBox `__ virtual machine. Prepare ------- Debian/Ubuntu ~~~~~~~~~~~~~ After a fresh install of Ubuntu 16.04 LTS 64-bit Server, first make sure your system packages are fully up to date: :: sudo apt-get update sudo apt-get -y dist-upgrade Then install the prerequisites: :: sudo apt-get -y install build-essential libssl-dev libffi-dev \ libreadline-dev libbz2-dev libsqlite3-dev libncurses5-dev \ libsnappy-dev libunwind-dev Snap ~~~~ To install crossbar from snap use below command :: snap install crossbar .. note:: For our PyPy variant, install crossbar-pypy instead. .. note:: Snaps are strictly confined to their environment, so is it not possible to access arbitrary binaries on your system. Because of it some functionalities of Crossbar may not work. CentOS 7 ~~~~~~~~ After a fresh install of CentOS 7 64bit, first make sure your system packages are fully up to date: :: sudo yum update Then install the prerequisites: :: yum install gcc gcc-c++ make openssl-devel libffi-devel \ libsnappy-devel libunwind-devel Now continue to build for: 1. `CPython <#install-for-cpython>`__ or 2. `PyPy <#install-for-pypy>`__ Crossbar.io can be run using regular Python (CPython) or PyPy, a Just-in-Time-Compiler for Python. The latter speeds up the Python code, so that Crossbar.io is more performant (lower latencies, higher possible throughput). On the downside, Crossbar. io running on PyPy requires more memory, takes longer to start up, and the speed increases require some period of operation (the JIT-compiler needs some data about actual program execution to work with). The instructions here are for Python 2.7, but Crossbar.io runs on Python >=3.5 as well. PyPy support for Python 3.5 may be incomplete, so for PyPy and for the time being, it's best to use Python 2.7. Install for CPython ------------------- After the `prepare-step <#prepare>`__, build Python from vanilla sources and install it to your home directory: :: cd $HOME wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tar.xz tar xvf Python-2.7.13.tar.xz cd Python-2.7.13 ./configure --prefix=$HOME/python2713 make make install () Install `Pip `__ and make sure it is the latest version: :: ~/python2713/bin/python -m ensurepip ~/python2713/bin/python -m pip install -U pip Install Crossbar and its dependencies from `PyPI `__: :: ~/python2713/bin/pip install crossbar Check the Crossbar installation: .. code:: console $ ~/python2713/bin/crossbar version __ __ __ __ __ __ __ __ / `|__)/ \/__`/__`|__) /\ |__) |/ \ \__,| \\__/.__/.__/|__)/~~\| \. |\__/ Crossbar.io : 0.13.2 Autobahn : 0.14.0 (with JSON, MessagePack, CBOR) Twisted : 16.1.1-EPollReactor LMDB : 0.89/lmdb-0.9.18 Python : 2.7.11/CPython OS : Linux-4.4.0-22-generic-x86_64-with-debian-stretch-sid Machine : x86_64 If everything went fine, add the following to your ``$HOME/.profile``: .. code:: shell export PATH=${HOME}/python2713/bin:${PATH} Install for PyPy ---------------- After the `prepare-step <#prepare>`__, install PyPy to your home directory: :: cd $HOME wget https://bitbucket.org/pypy/pypy/downloads/pypy-5.1.1-linux64.tar.bz2 tar xvjf pypy-5.1.1-linux64.tar.bz2 Install `Pip `__ and make sure it is the latest version: :: ~/pypy-5.1.1-linux64/bin/pypy -m ensurepip ~/pypy-5.1.1-linux64/bin/pypy -m pip install -U pip Now, to install Crossbar from `PyPI `__: :: ~/pypy-5.1.1-linux64/bin/pip install crossbar Check the Crossbar installation: .. code:: console $ ~/pypy-5.1.1-linux64/bin/crossbar version __ __ __ __ __ __ __ __ / `|__)/ \/__`/__`|__) /\ |__) |/ \ \__,| \\__/.__/.__/|__)/~~\| \. |\__/ Crossbar.io : 0.13.2 Autobahn : 0.14.0 (with JSON, MessagePack, CBOR) Twisted : 16.1.1-EPollReactor LMDB : 0.89/lmdb-0.9.18 Python : 2.7.10/PyPy-5.1.1 OS : Linux-4.4.0-22-generic-x86_64-with-debian-stretch-sid Machine : x86_64 If everything went fine, add the following to your ``$HOME/.profile``: .. code:: shell export PATH=${HOME}/pypy-5.1.1-linux64/bin:${PATH} Updating to newest release -------------------------- Once you've installed Crossbar.io, you can update to the newest release version at any time by doing :: pip install -U crossbar Updating to current develepment version --------------------------------------- If you want to update to the most current development version (e.g. for testing), you can do so from the git repository. Cloning the repo ~~~~~~~~~~~~~~~~ Note: The Amazon EC2 or Microsoft Azure images we provide already have the git repository cloned.\* You need to have `git `__ installed. Then clone the repository into a directory ``crossbar`` in your current directory. If you're not registered on GitHub you can clone the repository by doing :: git clone https://github.com/crossbario/crossbar.git else we suggest using SSH :: git clone git@github.com:crossbario/crossbar.git If you want to name the directory differently, just add that directory name at the end, e.g. Pulling changes ~~~~~~~~~~~~~~~ Unless you've just cloned the repository, you need to update it before installing. In a shell, in the repository directory, do :: git pull Update Crossbar.io ------------------ Then you can update your Crossbar.io installation by doing :: cd crossbar pip install --upgrade -e . On Windows, this will most likely require installing the `Microsoft Visual C++ Compiler for Python 2.7 `__.
