Reference Server

Share

In this tutorial we will learn to install Java JDK and JRE on centOS server.

Prerequisite

It is assumed that you have wget installed.

Use the following command in the terminal to install wget.

yum install -y wget

Use sudo if you don't have the permissions.

Step 1 Download JRE

In this tutorial we will be installing JRE (Java Runtime Environment) version 7.

Open terminal and login to your server using ssh. Now cd to a directory where you want to download the files.

Lets say we have a Downloads directory and we want to download JRE in that folder.

Type the following command in the terminal to download JRE version 7.

wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/7u79-b15/jre-7u79-linux-x64.rpm"

Output

[~]# cd Downloads
[Downloads]# wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/7u79-b15/jre-7u79-linux-x64.rpm"

Step 5 Set the environment

Now, open the .bash_profile file and set the JAVA_HOME and JRE_HOME.

[Downloads]# cd
[~]# ls -la
total 96
dr-xr-x---.  8 root root  4096 Dec 31 20:15 .
drwxr-xr-x  18 root root  4096 Dec 29 06:15 ..
-rw-------.  1 root root 11146 Dec 31 20:39 .bash_history
-rw-r--r--.  1 root root    18 Dec 29  2013 .bash_logout
-rw-r--r--   1 root root   429 Dec 31 10:38 .bash_profile

Open the .bash_profile file using vi or vim.

[~]# vi .bash_profile

And now add the following lines. Press i key to switch into INSERT mode.

export JAVA_HOME=/usr/java/jdk1.7.0_79
export JRE_HOME=/usr/java/jdk.7.0_79/jre

PATH=$HOME/bin:$JAVA_HOME/bin:$JRE_HOME:$PATH

Press Esc key to come out of the INSERT mode. Now type :wq to save the changes and exit.

Now, load the changes using source command.

[~]# source .bash_profile

All set, now check the Java version by typing the following command in the terminal.

[~]# java -version
java version "1.7.0_79"
