- If an entry for tomcat7 does not exist in /etc/init.d/tomcat7 then you will need to create one. Attached to this issue is a file, initd-tomcat7. Open the file and copy the contents into sudo vi /etc/init.d/tomcat7. Save the file (e.g. :wq).
If an entry for tomcat7 already exists be sure it contains a similar if not identical code as the attached file otherwise the Tomcat server may not be correctly started. - Finally to be sure the the script will be executed upon startup run the following command sudo chkconfig /etc/init.d/tomcat7

Tomcat installation/update:
- If the server does not already have a directory, /opt/apache-tomcat, then create one (sudo mkdir /opt/apache-tomcat) and download the tomcat installation to this directory. Be sure to check the sha1 or md5 hash on the download site is the same as for the downloaded tomcat file (e.g. openssl dgst -md5 apache-tomcat-7.0.xx.tar.gz).
- Untar the tomcat distribution and delete the tar file (sudo tar cxf apache-tomcat-7.0.xx.tar.gz).
- If the directory, /opt/apache-tomcat, did not exist create a "current" symlink to the new tomcat server directory (e.g. sudo ln -s apache-tomcat-7.0.xx current). If the directory, /opt/apache-tomcat, did exist and the link, current, was already there then you will need to sudo unlink current before linking it again. NOTE: The reason for symlinking the directory is so any references to the current tomcat server (e.g. $CATALINA_HOME, /etc/init.d/tomcat7...) do not have to be updated. This simplifies maintenance.
- This concludes the steps necessary to install or update the version of Tomcat. Please see Tomcat configuration for steps required to configure Tomcat.
