This article introduces you how to configure Java environment in Linux, the content is very detailed, interested friends can refer to it, I hope it can help you.

Download JDK

First log on to JDK official website and select the JDK version you want. Here we use JDK 8:

Click JDK Download and select the download format:

Select the Linux-x64 archive here and click Download.

install the JDK

Once the download is complete, move the JDK package to a directory in Linux.

On Linux systems, we install our own software in either/usr/local or/usr/lib. But this is not mandatory, installation in other is also possible, but in the configuration of some environment variables, be sure to write the path correctly.

Here, I installed it in/usr/local/java directory:

Then cd to that directory and extract the file: tar -zxvf jdk-8u241-linux-x64.tar.gz

After waiting for the decompression to complete, a jdk folder will be generated under the sibling directory:

At this point, JDK has been successfully installed.

Configuring Java Environment Variables

After installing JDK, you need to configure environment variables. Edit the/etc/profile file:

To configure Java environment variables, place the following four lines of code at the end of this file: Note your JDK version number:

export JAVA_HOME=/usr/lib/jdk1.8.0_241

export JRE_HOME=${JAVA_HOME}/jre

export CLASSPATH=.:$ {JAVA_HOME}/lib:${JRE_HOME}/lib

export PATH=${JAVA_HOME}/bin:$PATH

When the modification is complete, save and exit. Then execute the source /etc/profile command to make the configuration take effect.

Then you can view java version information with java -version command:
