Download a copy of Apache Tomcat 7 core, available at the [Tomcat download page](http://tomcat.apache.org/download-70.cgi).

Install Tomcat by extracting the downloaded archive. Extract the archive to your home folder, /Users/<username>. For convenience, you can rename the resulting folder from apache-tomcat-7.0.59 to tomcat.

1. Go into ./tomcat/webapps/. Delete the ROOT folder and ROOT.war.

2. Next, go to the [Lucee download page](https://bitbucket.org/lucee/lucee/downloads) and download the latest lucee war file.

3. Rename the lucee war file to ROOT.war (note the capitalization).

4. Copy the renamed ROOT.war file into ./tomcat/webapps.

5. Create a directory called lucee in ./tomcat.

6. Extract the contents of ROOT.war.

7. Go into ./tomcat/webappsROOT/WEB-INF/lib and copy everything in that folder to ./tomcat/lucee.

8. Go into ./tomcat/bin. ​

9. Create a file called setenv.sh. Tomcat uses this file to set environment variables on startup. Open the file and add this line:

    JAVA_OPTS="-Xms256m -Xmx1024m -XX:MaxPermSize=128m  -javaagent:${CATALINA_HOME}/lucee/lucee-inst.jar";  

10. Go into ./tomcat/conf.

11. Open catalina.properties. Replace the commented line in this text with the new line:

 #common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar
  common.loader=${catalina.home}/lib,${catalina.home}/lib/*.jar,${catalina.home}/lucee,${catalina.home}/lucee/*.jar 

12. Open a Terminal prompt. Follow these commands:

    $ cd tomcat/bin
    $ chmod 775 *
​    $ ./startup.sh 

13. Next, open a web browser to localhost:8080/lucee/admin/web.cfm. You should see the Lucee Web admin login screen. Lucee is now installed.

Next Steps

From this point you can configure your Tomcat instance and set up your applications in Lucee.
