Liferay Deployment Installation

In this article, we deploy the sample as a Liferay6.1 version.

Get ready:

Because this article needs to use the Liferay database as a single sign-on authentication database, we need to install the Liferay database on Mysql. Mysql Download and install this article does not make a prefix. The installation and configuration of Liferay is briefly described here. Liferay can be downloaded from the official website to the latest version of the installation package.

Liferay installation package Download Address:
http://sourceforge.net/projects/lportal/files/Liferay%20Portal/6.1.0%20GA1/ Liferay-portal-tomcat-6.1.0-ce-ga1-20120106155615760.zip/download

Install Liferay:

Liferay initializes the database at startup.

Unzip the download to the installation package Liferay-portal-tomcat-6.1.0-ce-ga1-20120106155615760.zip to the installation directory in the path liferay-portal-6.1.0-ce-ga1\ Tomcat-7.0.23\bin find the Startup.bat boot file and execute it. By default, Liferay uses hypersonic as the default database, and on the first visit we can configure parameters such as database, Admin user, and so on. When the Tomcat server is started, we have access to http://localhost:8080/. If a basic Configuration page appears, the deployment is successful. Next, we can make some basic settings for Liferay on this configuration page. The first thing we need to do is change the default database to the Mysql database we want to use. Click (change) as shown in Figure 2:

Figure 2. Liferay Configuration page

Here we modify the link URL of the database to our new database address. When finished, click Finish configuration. At this point, Liferay initializes the database based on the new configuration parameters and the database address. The Liferay installation completes when the following interface appears:
