Preparing a Linux machine for the Labs

This document provides the steps to install the software necessary for the lab exercises on a Linux machine. The instructions are written using an Ubuntu system.

1. Install curl
2. Install IBM Cloud Developer Tools
3. Install Java JDK 1.8
4. Create JAVA_HOME environment variable
5. Install node.js

Step 1: Install curl

1. Update all the component installation packages for your operating system.

    sudo apt-get update && sudo apt-get dist-upgrade
   

2. Run the following command (At the message Do you want to continue, type Y):

    sudo apt-get install curl
   

3. When the installation is complete, verify that it was successful by typing

    curl https://www.google.com
   

4. Verify that the response is HTML for the Google home page.
   NOTE: If the response is The document has moved, then curl was successfully installed, but the url is not correct. According to your geography, you need to change the extension.

Step 2: Install the IBM Cloud Developer Tools

1. Follow the instructions at Getting started with the IBM Cloud CLI to install the IBM Cloud Developer Tools.

Step 3: Install & Configure Java

1. From your command line, enter the following command:

   sudo apt-get install openjdk-8-jdk
   export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
   export PATH=$PATH:$JAVA_HOME/bin
   

2. To make these definitions persist over new sessions and reboots, enter your environment variable definitions into your profile.

    sudo vi /etc/profile
   

   Add the following statements to the end of the file, and save and close it.

    export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
    export PATH=$PATH:$JAVA_HOME/bin
   

Step 4: Install node.js

Ubuntu includes Node.js in its default repositories. The version that was used for this installation was 4.2.6. Your version might be different.

1. Install it by typing the apt install command (At the message Do you want to continue, type Y):

    sudo apt install nodejs
   

2. Verify the installation:

    node -v  js
   

3. The response is the version number (for example, v4.2.6).

4. Install the Node Package Manager (npm) (at the message Do you want to continue, type Y):

    sudo apt install npm
   

5. Verify the installation:

    npm version
   

6. You should see a JSON object similar to this:

   { npm: '3.5.2',
     ares: '1.10.1-DEV',
     http_parser: '2.5.0',
     icu: '55.1',
     modules: '46',
     node: '4.2.6',
     openssl: '1.0.2g-fips',
     uv: '1.8.0',
     v8: '4.5.103.35',
     zlib: '1.2.8' }
