In this tutorial, we will show you how to install Liferay on Debian 9 server.
- A server running Debian 9.
- A non-root user with sudo privileges.
Update the System
Before starting, update the system with the latest version. You can do this with the following command:
sudo apt-get update -y
sudo apt-get upgrade -y
Once your system is up-to-date, restart the system to apply all the updates.
Xwiki is a Java based application, so you will need to install Java 8 first. By default Java 8 is not available in the Debian 9 repository. You can install Java 8 by adding the webupd8team PPA repository to your system.
First, add the PPA by running the following command:
sudo add-apt-repository ppa:webupd8team/java
Next, update the repository with the following command:
sudo apt-get update -y
Once the repository is up to date, you can install Java 8 by running the following command:
sudo apt-get install oracle-java8-installer -y
After installing Java, you can check the version of Java with the following command:
You should see the following output:
java version "1.8.0_161" Java(TM) SE Runtime Environment (build 1.8.0_161-b12) Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)
By default, the latest version of the MariaDB is not available in Debian 9 default repository. So you will need to add the MariaDB repository to your system. You can add the repository by running the following command:
sudo apt-get install software-properties-common -y
sudo apt-key adv –recv-keys –keyserver keyserver.ubuntu.com 0xF1656F24C74CD1D8
sudo add-apt-repository ‘deb [arch=amd64] http://www.ftp.saix.net/DB/mariadb/repo/10.1/debian stretch main’
Next, update the repository by running the following command:
sudo apt-get update -y
Finally, install the MariaDB server with the following command:
sudo apt-get install mariadb-server -y
By default, MariaDB installation is not secured. So you will need to secure it first. You can do this by running the
Answer all the questions as shown below:
Enter current password for root (enter for none): Enter Set root password? [Y/n]: Y New password: Re-enter new password: Remove anonymous users? [Y/n]: Y Disallow root login remotely? [Y/n]: Y Remove test database and access to it? [Y/n]: Y Reload privilege tables now? [Y/n]: Y
The above script will set the root password, remove test database, remove anonymous user and Disallow root login from a remote location.
Once the MariaDB installation is secured, start the MariaDB service and enable it to start on boot time by running the following command:
sudo systemctl start mysql
sudo systemctl enable mysql
Next, you will need to create a database and user for liferay. First, log in to MariaDB shell using the following command:
mysql -u root -p
Enter your root password, then create a database for liferay with the following command:
MariaDB [(none)]>CREATE DATABASE lportal;
Next, create a username and password for liferay with the following command:
MariaDB [(none)]>CREATE USER ‘lportal’@’localhost’ IDENTIFIED BY ‘password’;
Next, grant privileges to the lportal database with the following command:
MariaDB [(none)]>GRANT ALL PRIVILEGES ON lportal.* TO ‘lportal’@’localhost’;
Next, flush the privileges with the following command:
MariaDB [(none)]>flush privileges;
Finally close the MySQL console:
Download and Install Liferay
First, you will need to download the latest version of the Liferay application bundled with Apache Tomcat. You can download it with the following command:
Once the download is completed, extract the downloaded file with the following command:
Next, copy the extracted directory to the /var/ directory:
sudo cp -r liferay-ce-portal-7.0-ga5 /var/liferay
Next, you will need to create a new portal-ext.properties file and add MySQL details. You can do this using the following command:
sudo nano /var/liferay/tomcat-8.0.32/webapps/ROOT/WEB-INF/classes/portal-ext.properties
Add the following lines:
jdbc.default.url=jdbc:mysql://localhost/lportal?useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=false jdbc.default.driverClassName=com.mysql.jdbc.Driver jdbc.default.username=lportal jdbc.default.password=password
Save and close the file, when you are finished.
Now, start the Liferay Portal installation by running the following script:
sudo bash /var/liferay/tomcat-8.0.32/bin/startup.sh
Wait some time for application to be fully started. You can see the application log using the following command:
tail -f /var/liferay/tomcat-8.0.32/logs/catalina.out
Once the application is fully started, open your web browser and type the URL http://your-server-ip:8080, you will be redirected to the Liferay Application Portal.
Congratulations! you have successfully installed Liferay Portal on your Debian 9 server.
