Installing Selenium Server

The Selenium RC server is simply a Java jar file (selenium-server-standalone-<version-number>.jar), which doesn’t require any special installation. Just downloading the zip file and extracting the server in the desired
directory is sufficient.

Running Selenium Server

Before starting any tests you must start the server. Go to the directory where Selenium RC’s server is located and run the following from a command-line console.
java -jar selenium-server-standalone-<version-number>.jar
