Click here to jump to our simple, step-by-step instructions for installing the Tomcat binary distribution on a Linux machine. The Mac OS X installation process is fairly painless and straightforward, but there are a few rough spots along the way. Follow these step by step instructions to get Tomcat up and running on your Mac OS X machine in no time.
Tomcat finds certain resources, such as your Java runtimes, by reading values from your environment variables. If you are new to the Mac platform, and you are wondering why there's been no mention of installing Java, don't worry. You can substitute your favorite text editor. We like Vim. Next, download the most recent stable build of Tomcat from an Apache project mirror site.
If you're worried about checksum, be sure to run a checksum on the package with the 'md5' Terminal command and match it against the value provided on the Apache site.
By default, the unpacked folder name will be something like 'apache-tomcat-x-x-xx'. For ease of use, change it to 'Tomcat'. You should now be able to start Tomcat by navigating to the 'bin' folder and executing 'startup.
