caGrid 1.3 Host Configuration

The following represent the instructions to enable networking once the VM/Host machine has been created and is up and running.

STEP 1: Enable the Network

Once the VM is created and started, follow the instructions below to enable networking:

These instructions apply to CentOS 5 Linux distribution.

1. Open the network configuration GUI and enter the following information: 

   system-config-network-tui

   1. Select > eth0 and hit > return
   2. Deselect > DHCP 
   3. In the Static IP field enter > <static_ip>
   4. In the Netmask field enter > <netmask_ip>
   5. In the Default gateway IP field enter > <gateway_ip>
      
2. Edit resolv.conf: 

   vi /etc/resolv.conf

   
   

3. Add search domain:

   nameserver static_ip

   
   

4. Edit ifcgc-eth0:

   vi /etc/sysconfig/networking/profiles/default/ifcfg-eth0

   
   

5. Add > "HOSTNAME=hostname.domain.org"
   
   
6. Edit /etc/hosts:

   vi /etc/hosts

   
   

7. Add > "type_static_ip hostname.domain.org hostname"

STEP 2: Time Synchronization

To ensure that the host's clock has the correct time, synchronize the clock with a time service.

1. NTP time servers are available at:http://www.pool.ntp.org.

STEP 3: User Accounts

The following represents an example of a User Account.

1. User account "griduser" was created with the /home/griduser as the home directory. The folder layout is provided in the table below:

Folder layout

STEP 4: Software

Required software is based on the CBIIT Tech Stack

The following are the instructions to manually install the required Software:

1. Java 1.5.0_14

   1. Go to the following URL to select your Java distribution and follow the install instructions: [Sun JDK 1.5.0_14 Download Site]. 
   2. Once you have installed Java JDK 1.5, > set the environment variable JAVA_HOME to the root directory of the JDK. 
      

      Note: This should be done in a way that will cause JAVA_HOME to be set to the proper value when users log in and also when grid services are automatically launched when a VM boots up.  In a Linux environment, you can set this up by putting an appropriate export command in /etc/profile. In a Windows environment, use the control panel to set JAVA_HOME as a system environment variable.
