Step 1: Verify That JDK 1.5 is Installed

It is important to install JDK from SUN.

Step 2: Install Ant 1.7

With "Could not create task or type of type: replaceregexp" bug might be useful "yum install ant-nodeps"

Step 3: Installing Selenium Grid

3.1 Download the latest version of Selenium Grid from http://selenium-grid.seleniumhq.org/download.html

3.2 Unzip the file into a directory of your choosing (say /usr/local/selenium-grid-1.0). We will refer to the directory where Selenium Grid is installed as "Selenium Grid Home". For instance if you unzipped the distribution within /usr/local/selenium-grid-1.0, your Selenium Grid Home is /usr/local/selenium-grid-1.0.

3.3 Verify the Selenium Grid install: from the terminal window go to the Selenium Grid home directory and run: ant sanity-check

In case "No supported regular expression matcher found: java.lang.ClassNotFoundException: org.apache.tools.ant.util.regexp.Jdk14RegexpRegexp" bug "yum install ant-apache-regexp" might helps.
