Start Linux Virtual Machines

The ambari-vagrant directory (cloned from GitHub) contains several subdirectories, each for several a specific Linux distributionsdistribution. Each subdirectory contains a set of has scripts and configuration files for running Ambari and HDP on that version of Linux.

...

1.  Change your current directory to ambari-vagrant:

   Code Block
   cd ambari-vagrant

   You will see subdirectories for different OS’s.

2. cd into the OS subdirectory for the OS you wish to use. CentOS 6.4 is recommended, because it is quicker to launch than other OS's.
   The remainder of this Quick Start uses CentOS 6.4. To install and use another version or distribution of Linux, specify the other directory name in place of centos6.4

   Code Block
   cd centos6.4

3. Copy the private key into your OS directory:

   Code Block
   cp ~/.vagrant.d/insecure_private_key .

4. (Optional) If you have at least 16 GM of memory on your Mac, consider increasing the amount of memory allocated to the VMs. Edit the following line in Vagrantfile, increasing 3072 to 4096 or more:

   Code Block
   vb.customize ["modifyvm", :id, "--memory", 3072] # RAM allocated to each VM

5. Start one or more VMs, using the ./up.sh command. Three seems to be a good number if you have 16GB of RAM, without taxing the system too much.

   Code Block
   ./up.sh <# of VMs to launch>

   For example, up.sh 3 on CentOS 6.4 starts 3 VMs. Associated hostnames will be c6401, c6402, and c6403.

   Additional notes:
   - With the default Vagrantfile (in each OS subdirectory) you can specify up to 10 VMs. (If your computer can handle it; you can even add more.)
   - VMs will have fully-qualified domain names (FQDN) with the format <os-code>[01-10].ambari.apache.org, where <os-code> is c59 (CentOS 5.9), c64 (CentOS 6.4), etc. For example, c5901.ambari.apache.org, c6401.ambari.apache.org, etc.
   - VMs will have IP addresses 192.168.<os-subnet>.1[01-10], where <os-subnet> is 59 for CentOS 5.9, 64 for CentOS 6.4, etc. For example, 192.168.59.101 for CentOS 5.9 node c5901,  192.168.64.101, for CentOS 6.4 node c6401, etc.
   - Note that up.sh 3 is equivalent to doing something like vagrant up c640{1..3}

...

Install Ambari

If it is your first time running a vagrant command, run:

vagrant init

Log into the VM:

vagrant ssh c6401

Note that this logs you in as user vagrant. Once you are logged in, you can run:

sudo su -

...

After running the vagrant up command:

1. Check the status of your VMs:

   Code Block
   hw100:centos6.4 lkg$ vagrant status Current machine states: c6401 running (virtualbox) c6402 running (virtualbox) c6403 running (virtualbox) c6404 not created (virtualbox) c6405 not created (virtualbox) c6406 not created (virtualbox) c6407 not created (virtualbox) c6408 not created (virtualbox) c6409 not created (virtualbox) c6410 not created (virtualbox)

   (The vagrant init command initializes your current directory to be a Vagrant environment, but this should already be handled within the repository.)

2. Next, log into the VM:

   Code Block
   vagrant ssh c6401

   From this point onward, until you exit the VM, your terminal window will operate within the VM – not your Mac.

3. When you first access the VM you will be logged in as user vagrant. Change to root user:

   Code Block
   sudo su -

4. Download the Ambari repository file. The following commands download Ambari version 2.2.1.0:
