You should be able to launch Tomcat immediately from thebin directory, making sure to be the tomcat user.[server1]$ su Tomcat[server1]$ cd Tomcat/bin[server1]$ ./startup.shAt this point, you should be able to connect to Tomcat via a URL such as http://localhost:8080.If this does not return the Tomcat front page, then something is wrong with your setup.
