Installing Tomcat 7 On Mac OS X

By LotusshaneyTech

Tomcat 7 is the first Apache Tomcat release to support the Servlet 3.0, JSP 2.2, and EL 2.2 specifications. Please note that Tomcat 7 requires Java 1.6 or better, but that shouldn’t be a problem, if you are running OS X 10.5 or 10.6.

On OS X 10.7 and 10.8 (Mnt Lion) however, Java is initially not installed anymore. The easiest way to get Java onto your Mac is probably to open the Terminal app and enter java. You will be asked if you want to install it and OS X takes care of the rest – you would end up with Java 6, or you could install Java 7 directly from Oracle.

Whatever you do, when opening Terminal and running java -version, you should see something like this:

java version "1.6.0_37"
Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)
Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)

or this:

java version "1.7.0_25"
Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)
Here are the easy to follow steps to get it up and running on your Mac

 

  1. Download a binary distribution of the core module: apache-tomcat-7.0.42.tar.gz from here. I picked the tar.gz in Binary Distributions / Core section.
  2. Opening/unarchiving the archive will create a folder structure in your Downloadsfolder: (btw, this free Unarchiver app is perfect for all kinds of compressed files and superior to the built-in Archive Utility.app)
    ~/Downloads/apache-tomcat-7.0.42
  3. Open to Terminal app to move the unarchived distribution to /usr/local
    sudo mkdir -p /usr/local
    sudo mv ~/Downloads/apache-tomcat-7.0.42 /usr/local
  4. To make it easy to replace this release with future releases, we are going to create a symbolic link that we are going to use when referring to Tomcat (after removing the old link, you might have from installing a previous version):
    sudo rm -f /Library/Tomcat
    sudo ln -s /usr/local/apache-tomcat-7.0.42 /Library/Tomcat
  5. Change ownership of the /Library/Tomcat folder hierarchy:
    sudo chown -R <your_username> /Library/Tomcat
  6. Make all scripts executable:
    sudo chmod +x /Library/Tomcat/bin/*.sh

Instead of using the start and stop scripts, like so:

you may also want to check out Activata’s Tomcat Controller a tiny freeware app, providing a UI to quickly start/stop Tomcat. It may not say so, but Tomcat Controller works in OS X 10.8.x just fine.

Finally, after your started Tomcat, open your Mac’s Web browser and take a look at the default page: http://localhost:8080
