Getting Started

Downloading Mesos

There are different ways you can get Mesos:

1. Download the latest stable release from Apache (Recommended)

$ wget http://www.apache.org/dist/mesos/0.28.2/mesos-0.28.2.tar.gz
$ tar -zxf mesos-0.28.2.tar.gz

2. Clone the Mesos git repository (Advanced Users Only)

$ git clone https://git-wip-us.apache.org/repos/asf/mesos.git

NOTE: If you have problems running the above commands, you may need to first run through the System Requirements section below to install the wget, tar, and git utilities for your system.

System Requirements

Mesos runs on Linux (64 Bit) and Mac OS X (64 Bit). To build Mesos from source, GCC 4.8.1+ or Clang 3.5+ is required.

For full support of process isolation under Linux a recent kernel >=3.10 is required.

Make sure your hostname is resolvable via DNS or via /etc/hosts to allow full support of Docker’s host-networking capabilities, needed for some of the Mesos tests. When in doubt, please validate that /etc/hosts contains your hostname.

Ubuntu 14.04

Following are the instructions for stock Ubuntu 14.04. If you are using a different OS, please install the packages accordingly.

# Make the just installed kernel the one booted by default, and reboot.
$ sudo sed -i 's/default=1/default=0/g' /boot/grub/grub.conf
$ sudo reboot

# Install a few utility tools. This also forces an update of `nss`,
# which is necessary for the Java bindings to build properly.
$ sudo yum install -y tar wget git which nss

# 'Mesos > 0.21.0' requires a C++ compiler with full C++11 support,
# (e.g. GCC > 4.8) which is available via 'devtoolset-2'.
# Fetch the Scientific Linux CERN devtoolset repo file.
$ sudo wget -O /etc/yum.repos.d/slc6-devtoolset.repo http://linuxsoft.cern.ch/cern/devtoolset/slc6-devtoolset.repo

# Import the CERN GPG key.
$ sudo rpm --import http://linuxsoft.cern.ch/cern/centos/7/os/x86_64/RPM-GPG-KEY-cern

# Fetch the Apache Maven repo file.
$ sudo wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo

# 'Mesos > 0.21.0' requires 'subversion > 1.8' devel package, which is
# not available in the default repositories.
# Create a WANdisco SVN repo file to install the correct version:

# Install essential development tools.
$ sudo yum groupinstall -y "Development Tools"

# Install 'devtoolset-2-toolchain' which includes GCC 4.8.2 and related packages.
$ sudo yum install -y devtoolset-2-toolchain

# Install other Mesos dependencies.
$ sudo yum install -y apache-maven python-devel java-1.7.0-openjdk-devel zlib-devel libcurl-devel openssl-devel cyrus-sasl-devel cyrus-sasl-md5 apr-devel subversion-devel apr-util-devel

# Enter a shell with 'devtoolset-2' enabled.
$ scl enable devtoolset-2 bash
$ g++ --version  # Make sure you've got GCC > 4.8!

# Process isolation is using cgroups that are managed by 'cgconfig'.
# The 'cgconfig' service is not started by default on CentOS 6.6.
# Also the default configuration does not attach the 'perf_event' subsystem.
# To do this, add 'perf_event = /cgroup/perf_event;' to the entries in '/etc/cgconfig.conf'.
$ sudo yum install -y libcgroup
$ sudo service cgconfig start

CentOS 7.1

Following are the instructions for stock CentOS 7.1. If you are using a different OS, please install the packages accordingly.

# Install a few utility tools
$ sudo yum install -y tar wget git

# Fetch the Apache Maven repo file.
$ sudo wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo

# Install the EPEL repo so that we can pull in 'libserf-1' as part of our
# subversion install below.
$ sudo yum install -y epel-release

# 'Mesos > 0.21.0' requires 'subversion > 1.8' devel package,
# which is not available in the default repositories.

# Parts of Mesos require systemd in order to operate. However, Mesos
# only supports versions of systemd that contain the 'Delegate' flag.
# This flag was first introduced in 'systemd version 218', which is
# lower than the default version installed by centos. Luckily, centos
# 7.1 has a patched 'systemd < 218' that contains the 'Delegate' flag.
# Explicity update systemd to this patched version.
$ sudo yum update systemd

# Install essential development tools.
$ sudo yum groupinstall -y "Development Tools"

# Install other Mesos dependencies.
$ sudo yum install -y apache-maven python-devel java-1.8.0-openjdk-devel zlib-devel libcurl-devel openssl-devel cyrus-sasl-devel cyrus-sasl-md5 apr-devel subversion-devel apr-util-devel

Building Mesos

# Change working directory.
$ cd mesos

# Bootstrap (Only required if building from git repository).
$ ./bootstrap

# Configure and build.
$ mkdir build
$ cd build
$ ../configure
$ make

In order to speed up the build and reduce verbosity of the logs, you can append -j <number of cores> V=0 to make.

# Run test suite.
$ make check

# Install (Optional).
$ make install

Examples

Mesos comes bundled with example frameworks written in C++, Java and Python. The framework binaries will only be available after running make check, as described in the Building Mesos section above.

# Change into build directory.
$ cd build

# Start mesos master (Ensure work directory exists and has proper permissions).
$ ./bin/mesos-master.sh --ip=127.0.0.1 --work_dir=/var/lib/mesos

# Start mesos agent.
$ ./bin/mesos-agent.sh --master=127.0.0.1:5050

# Visit the mesos web page.
$ http://127.0.0.1:5050

# Run C++ framework (Exits after successfully running some tasks.).
$ ./src/test-framework --master=127.0.0.1:5050

# Run Java framework (Exits after successfully running some tasks.).
$ ./src/examples/java/test-framework 127.0.0.1:5050

# Run Python framework (Exits after successfully running some tasks.).
$ ./src/examples/python/test-framework 127.0.0.1:5050

Note: These examples assume you are running Mesos on your local machine. Following them will not allow you to access the Mesos web page in a production environment (e.g. on AWS). For that you will need to specify the actual IP of your host when launching the Mesos master and ensure your firewall settings allow access to port 5050 from the outside world.
