To install Java in Redhat Enterprise Linux follow these steps:
- we are installing from OpenJDK rpm with command line
Run the following command to install the developer version of OpenJDK
# yum install java-1.7.0-openjdk-devel
- (Optional) It is sometimes required to set the JAVA_HOME path variable.
You can know the java path by
echo $JAVA_HOME
It will give the path where Java is
In my case it was something like :
/usr/lib/jvm/jre-1.8.0-openjdk/bin/java
remember it might be different in your case.
Now,
in .bashrc file which is in home directory lets add the java home path as:
I am editing the file in vim editor
[lx@localhost ~]$ vi .bashrc
at the bottom of file add the java path in following format:
export JAVA_HOME="/path/to/java/home"
in my case, I added:
#java home path
export JAVA_HOME="/usr/lib/jvm/jre-1.8.0-openjdk/bin/java"
To save first press Ctrl+ O and then
:wq
semicolon and then w and q and press enter.
You are done!
You can check the java version installed with:
java -version
My output was:
java version "1.7.0_141"
OpenJDK Runtime Environment (rhel-2.6.10.1.el7_3-x86_64 u141-b02)
OpenJDK 64-Bit Server VM (build 24.141-b02, mixed mode)
