How to configure SSL and HTTPS in Liferay

Let’s see how to enable the HTTPS access to Liferay portal. Firstly we need an SSL certificate that ensures the sending and receiving encrypted information. In this example we use the keytool line command to generate a “self-signed” certificate.

STEP 1. Generate the Tomcat server SSL key

$ cd /home/giuseppe/apps/liferay-portal-6.1.0-ce-ga1/tomcat-7.0.23/keyfiles

$ keytool -genkey -alias tomcatkey -keyalg RSA -keystore ./liferay_keystore

STEP 2. Configure the Tomcat server for SSL

$ vi  /home/giuseppe/apps/liferay-portal-6.1.0-ce-ga1/tomcat-7.0.23/conf/server.xml

<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
               maxThreads="150" scheme="https" secure="true"
               clientAuth="false" sslProtocol="TLS"
	       keystoreFile="/home/giuseppe/apps/liferay/liferay-portal-6.1.0-ce-ga1/tomcat-7.0.23/keyfiles/liferay_keystore" keystorePass="123456"/>

Start Tomcat. If no errors occur, you can see the following log message.
