Without the linking exception, components that linked to the Java class library would be subject to the terms of the GPL license.

Steps To Install OpenJDK 19 (Java 19) on Centos 7

To complete this guide, you must log in to your server as a non-root user with sudo privileges. To do this, you can follow our guide on Initial Server Setup with Centos 7.

Install Java 19 on Centos 7

First, you need to update your local package index with the command below:

sudo yum update -y

Then install the required packages by using the following command:

sudo yum install curl wget -y

Download OpenJDK 19

At this point, you need to visit the JDK Downloads page to download the latest archive by using the wget command:

sudo wget https://download.java.net/java/GA/jdk19.0.1/afdd2e245b014143b62ccb916125e3ce/10/GPL/openjdk-19.0.1_linux-x64_bin.tar.gz

Then, extract your downloaded file with the command below:

sudo tar xvf openjdk-19.0.1_linux-x64_bin.tar.gz

Next, move your extracted file to the /opt directory:

sudo mv jdk-19.0.1 /opt/

Configure Java Environment Path

At this point, you need to configure the Java home path by using the following command:

sudo tee /etc/profile.d/jdk19.sh <<EOF
export JAVA_HOME=/opt/jdk-19.0.1
export PATH=\$PATH:\$JAVA_HOME/bin
EOF

Source your profile file with the following command:

source /etc/profile.d/jdk19.sh

Verify your Java Home path:

echo $JAVA_HOME
Output
/opt/jdk-19.0.1

Also, you can verify your Java installation by checking its version:

java -version
