3.2. Installing Turbolinux Cluster LoadBalancer 10
Installing Turbolinux Cluster LoadBalancer 10 is simple if you follow these steps and allow the installation program to guide you through the process. As with any software installation, you will need to be logged in as root to perform these steps.
Login as root.
Insert the Turbolinux Cluster LoadBalancer 10 installation CD-ROM and mount the CD-ROM.
# mount /mnt/cdrom
Change to the directory that the CD-ROM is mounted :
# cd /mnt/cdrom
Start the installation program.
# ./TLCLB-install
The installation program first determines what Linux distribution it is running under. The currently supported distributions is the Turbolinux 10 Server. If the installation program is unable to detect a supported system, it will exit.
There is a test mode available via the --test or -t option, which will not actually install anything, but will instead validate that all the prerequisites exist in order to install successfully. There is also help available with -- help or -h, which gives you the syntax and options available.
The welcome screen will appear. Press ENTER to continue.
Read the entire license when it appears before you continue with the installation. You can use the cursor keys to scroll through the text. Once you've read the license, you can click `I agree' to continue. If you choose not to agree with the license, clicking `Exit' will exit the installation program and return you to the prompt.
After you agree to the licensing terms, the program will attempt to determine what distribution of Linux you are running. If it is successful, it will display the name of the distribution along with the kernel version, as shown in the figure below.
Press ENTER to continue.
This brings you to the installation menu. Your choices here are the guided install, , installation of the libraries and utilities. You can also access the documentation files from this menu. The menu is pictured below.
You should choose `Guided Install', which will walk you through the process and install all the necessary pieces. The other options are primarily used to install portions of the product at a later time, or if something goes wrong. The guided install just takes you through each section in turn.
The installer will present you with the administrative tools available. Accept the default, installing all of the listed packages.
These packages provide the functionality of the Turbolinux Cluster LoadBalancer 10 as well as several administration tools. Here is a brief overview of what they do:
The Cluster Management Console is a web-based tool that allows you to monitor and modify the cluster. It will be covered in Chapter 7 of this manual.
The Cluster Server daemon is a key component of the Turbolinux Cluster LoadBalancer 10 software. Do not uncheck it unless you are certain that it has already been installed.
The Cluster Agents (also called ASAs) allow you to monitor different services on the cluster nodes. They will be discussed in Chapter 8. You should install the cluster agents so that the cluster daemon can determine when a service on a cluster node becomes unavailable.
The TLCLB Administration tools include the menu-driven configuration programs. Unless you want to do all of your configuration by hand, be sure to install these.
Once you've selected the packages, click `Install', and the specified packages will be installed. Note that some additional packages, which are required by the selected packages, will be installed as well. The installation process may take a couple minutes.
Next you will be asked to enter some information in order to generate a secure key for the CMC web-based management system.
You may choose to have your certification validated by a commercial certificate authority such VeriSign or Thawte. However, the process of obtaining such a certificate is rather involved and is not necessary. If you do obtain such a certificate, store it in the cmc-cert-key.pem file in the /etc/clusterserver directory.
Click `OK' to proceed to the data entry screen.
The screen will ask you to enter various information about your organization. Enter the information as requested.
Click the `Generate' button, and an SSL authentication certificate will be generated for you. Click `OK' to proceed.
The SSL certificate is generated when you install Turbolinux Cluster LoadBalancer 10 and is valid for one year. You will need to re-generate a new SSL certificate using turboclusteradmin tool once the validation date has past. (Please refer to Section 7.4 for further information)
When you see the message " Turbolinux Cluster LoadBalancer installation finished", click on the`OK' button and you will return to the shell prompt.
The Turbolinux Cluster LoadBalancer 10 Install CD includes a required kernel update package. When using this CD to install Turbolinux Cluster LoadBalancer 10, this kernel update package is installed automatically. However, in order for your system to begin using the newly installed kernel, it must be rebooted.
# reboot
