Installing OpenNode 6

Installing OpenNode is much like installing any other modern Linux distribution. You start with a text based installer to configure some of the basic options, such as netwokring, then you are presented with a GUI to complete the install.

Download the ISO from the OpenNode website and burn it to a CD, or mount the ISO on your virtual machine.

The first screen you wil see when you boot the install CD is the boot menu. Press ENTER to start the install with default settings. You can use advanced boot options which are coved on my other blog post.

You will now need to specify your network settings. Move around this screen using the arrow keys and pressing SPACE on the item to enable. You will notice an asterix (*) next to each item which is enabled. Select Manual Configuration for IPv4 and disable Enable IPv6 support. 

Now enter your IPv4 address, submask, Gateway and Name Server (DNS server) for your network and press TAB to select OK.

Press 1 and ENTER to use the default file system layout. 

Press ENTER to confirm the changes and commit them to disk. 

The GUI will now load and you can use either your mouse or keyboard to navigate the screen. Select your language and press Next.

Type in the Hostname for your machine to use and press Next.

Choose your timezone by clicking areas on the map and press Next.

Enter the Root Password for your installation to use. This is the password you will use later to log into the system.

Press Next and the install will start. 

Once the installation completes, click Reboot to reboot your machine and boot from your new installation. 

You will be presented with the login screen when your machine restarts. Log in with root as the username and the password you set in the earlier install step. 

Now your install is complete and your OpenNode system is ready to be used. Before creating any VMs, it’s best to update your system using yum to make sure you have the latest bug fixes and security patches installed. Run the yum command to download and install the latest updates of all your installed packages. 

yum update

The yum application is downloading the latest list of available software and will update them once you have confirmed that you would like to proceed. 

Press y and ENTER to download and install the latest version and their dependencies of your installed packages. 

The first time you run yum update you will get warning about importing the GBG key. Press y and ENTER to accept.

Finally, you need to reboot to make sure all the new packages are used. Issue the command reboot at the prompt.

reboot

Wait for the operating system to load and you can start to use your new OpenNode installation. To get started, log back in and issue the command opennode to get started.

OpenNode does does not have a web based GUI installed by default. See my other blog post on setting up the web based GUI.
