1. Update the system

To start with the Maven installation, log in to your CentOS 7 server via SSH as user root

ssh root@IP_adress -p port_number

and perform a full system update by typing the following command

yum -y update

2. Install Java 8

Since Maven is Java based application we have to install Java on the server. Java version 1.7 or newer is required. We will install Java 8

yum install -y java-1.8.0-openjdk-devel

This command will install Java 8 and all necessary dependencies.

Once installed, run the following command the check the installed version

java -version

openjdk version "1.8.0_161"
OpenJDK Runtime Environment (build 1.8.0_161-b14)
OpenJDK 64-Bit Server VM (build 25.161-b14, mixed mode)

3. Install and configure Maven on CentOS 7

Apache Maven’s installation is a simple process. Go to their official website and download the arhive of the desired version. In this tutorial we will install Apache Maven version 3.5.3

wget http://mirrors.sonic.net/apache/maven/maven-3/3.5.3/binaries/apache-maven-3.5.3-bin.zip

Unpack the downloaded zip archive

yum -y install unzip
cd /opt
unzip apache-maven-3.5.3-bin.zip

Rename the newly created directory and remove the downloaded archive

mv apache-maven-3.5.3 maven
rm -f apache-maven-3.5.3-bin.zip

We downloaded the precompiled version of Apache Maven, so we have to set the environment variables. Create the following file

nano /etc/profile.d/maven.sh
export PATH=/opt/maven/bin:${PATH}

Save the file and load the environment variables in the current shell.

With this step Apache Maven should be successfully installed and configured on your CentOS 7 VPS. Run the following command to confirm

mvn -version

and you should get the following output

Apache Maven 3.5.3 (3383c37e1f9e9b3bc3df5050c29c8aff9f295297; 2018-02-24T13:49:05-06:00)
