🔧 1. Prerequisites

• Java JDK 8 or 11
• PostgreSQL 12 or later
• Liferay DXP 7.4 bundle (.zip)
• Liferay Developer Studio (Eclipse-based IDE)

🛠 2. Install and Configure PostgreSQL

1. Install PostgreSQL from official site.
2. Create a database and user for Liferay:

📦 3. Download and Extract Liferay DXP 7.4

• Obtain the Liferay DXP 7.4 bundle from your customer portal.
• Extract it to a preferred directory, e.g., C:\liferay\dxp-7.4

🔌 4. Configure Database Connection

Modify portal-ext.properties in liferay-dxp-7.4/tomcat-9.0.56/webapps/ROOT/WEB-INF/classes or create one in the root:

jdbc.default.driverClassName=org.postgresql.Driver
jdbc.default.url=jdbc:postgresql://localhost:5432/lportal
jdbc.default.username=liferayuser
jdbc.default.password=liferay

Place the PostgreSQL JDBC driver postgresql-.jar into:

liferay-dxp-7.4/tomcat-*/lib/ext

🚀 5. Start Liferay DXP

Start the server using:

cd liferay-dxp-7.4/tomcat-*/bin  
./startup.sh (Linux/macOS) OR startup.bat (Windows)

Wait for first-time setup and access:
