This can be accomplished with the following command: sudo alternatives -install /usr/bin/java java /opt/jre1.8.0_51/bin/java 1 Since we just extracted the file, we can go ahead and removed the download file with the following command: sudo rm /opt/jre-8u25-linux-圆4.tar.gzįurthermore, we will change the ownership permissions of the extracted files wth the following: sudo chown -R root: jre1.8.0_51įinally, we will then be using the “Alternatives” commands to create symbolic links from the /opt location to the /usr/bin/java. With the file downloaded to the /opt directory, We must extract the files with the following command: sudo tar xvf jre-8u51-linux-圆4.tar.gz sudo wget -no-cookies -no-check-certificate -header "Cookie: gpw_e24=http%3A%2F%2Foraclelicense=accept-securebackup-cookie" \ With the following command, you can download the latest version of Java Oracle JRE 8.51 from the Java site.
To keep things in order an prepare for the download, let us change directory to /opt. However, we would need to download the file from the Oracle site. Sudo yum install java-1.6.0-openjdk-devel Installing Oracle Java JRE on CentOS 7Īnother alternative Java install is with Oracle. Sudo yum install java-1.7.0-openjdk-devel Select one of the following versions of Java JDK, version 8 being the latest: sudo yum install java-1.8.0-openjdk-devel Sudo yum install java-1.6.0-openjdk Installing Java JDK on CentOS 7 Select one of the following versions of Java JRE, version 8 being the latest: sudo yum install java-1.8.0-openjdk sudo yum insatal wget Installing Java JRE on CentOS 7 In this tutorial we will be using the wget command, so let us install this now to facilitate the process later on. You need a CentOS 7 server that is configured with a static IP address.īefore we begin, let make sure that the server is fully updated with the following command: sudo yum update This how-to will take you through the installation of JRE and JDK on CentOS 7. JDK is a fully loaded Development Kit that has everything that JRE has plus additional resources to create/secure Applications and Applets. As the base model car, JRE enables the ability to create Java Applications for different types of deployments using minimal core tools to accomplish the task. There are two standard types of installations, JRE (Java Runtime Environment) and JDK (Java Development Kit). Well, that’s the same concept when we take a closer look at Java. If you had the option to choose between a base model car or a fully loaded model, which one would you choose? Both cars will take you from point A to point B, but with the fully loaded car you have additional features that can make rush hour a chill hour. Verified and Tested 08/10/15 Introduction
