CentOS Install Sun Java SE JRE

By • Sep 9th, 2009 • Category: Featured Linux, Linux

Here is how to install the Sun Java SE Runtime Environment (JRE) on CentOS 5.3.

First, Execute the Binary:

> mv jre-6u16-linux-x64.bin /usr/lib/java
> cd /usr/lib/java
> chmod 744 jre-6u16-linux-x64.bin
> ./jre-6u16-linux-x64.bin

Download the 32-bit or 64-bit non-RPM binary from Sun’s site here and execute it.

Next, Set Sun’s Java as Default:

> update-alternatives --install "/usr/bin/java" "java" "/usr/lib/java/jre1.6.0_16/bin/java" 1
> update-alternatives --set java /usr/lib/java/jre1.6.0_16/bin/java

We configure the system to use Sun’s Java binaries to execute “java” commands by telling it there is an alternate installation and to use it by default.

Finally, Check the Default Version:

> java -version
java version “1.6.0_16”
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) 64-Bit Server VM (build 14.2-b01, mixed mode)

is a technology junkie.

  1. Wow..very good…Nice blog and well updated…

  2. Very nice guide. I have a problem with the following part.

    [root@MattPC ~]# update-alternatives –set java /usr/lib/java/jre1.6.0_29/bin/java
    /usr/lib/java/jre1.6.0_29/bin/java has not been configured as an alternative for java

    Any ideas why this doesn’t work? I also still have the non SUN java as a default after this.
