Time for action – deploying Liferay

Next, follow these steps to configure Liferay with Tomcat:

Create a folder called Liferay, which we will refer to as LIFERAY_HOME from now on.
Extract the Tomcat zip file you have downloaded earlier to LIFERAY_HOME. You should see a folder named apache-tomcat-6.0.33 inside LIFERAY_HOME. From now on this folder will be referred to as TOMCAT_HOME.
Create a folder called ext inside TOMCAT_HOME/lib. Extract the Portal Dependencies jars zip that you downloaded earlier to this ext folder.
Copy the jars like mysql.jar, jta.jar, and mail.jar inside the TOMCAT_HOME/lib folder, which has been provided to you in the code folder of this chapter.
Create a file called ROOT.xml inside TOMCAT_HOME/conf/Catalina/localhost. Add the following content inside ROOT.xml:
```
<Context path=””>
</Context>
```
Open the file TOMCAT_HOME/conf/catalina.properties and find a property called common.loader. Append ${catalina.home}/lib/ext/*.jar at the end as follows:
```
common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar,${catalina.home}/lib/ext/*.jar 
```
Delete the contents inside TOMCAT_HOME/webapps/ROOT folder and extract the contents of Liferay Portal war that you downloaded before.
Open catalina.bat from TOMCAT_HOME/bin using a text editor. Find a line which starts with rem ----- Execute.

Below that line add the following to increase heap space and save the file:

set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m -XX:MaxPermSize=128m -Dfile.encoding=UTF8 -Duser.timezone=GMT

Start the server by double-clicking startup.bat inside TOMCAT_HOME/bin.
The server will start up and the default Liferay home page will be opened automatically in the browser.

You have just seen how to deploy Liferay in an existing Tomcat server.

Next let's see how we can configure a production database with Liferay.
