Editor to share with you how to configure jdk under Linux, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

I have successfully installed jdk (jdk-1_5_0_02-linux-i586.rpm) on Fedora Core 3, and the other versions of Linux are basically the same, the process is as follows:

1. First download jdk (jdk-1_5_0_02-linux-i586.rpm) from the Internet, recommend SUN's official website www.sun.com, download it and put it in the / home directory, of course, other places are fine.

Enter the installation directory

# cd / home

# cp jdk-1_5_0_02-linux-i586.rpm / usr/local

# cd / usr/local

Add executable permissions to all users

# chmod + x jdk-1_5_0_02-linux-i586.rpm.bin

#. / jdk-1_5_0_02-linux-i586.rpm.bin

The file jdk-1_5_0_02-linux-i586.rpm is generated, and executable permissions are also added to all users

# chmod + x jdk-1_5_0_02-linux-i586.rpm

Installation program

# rpm-ivh jdk-1_5_0_02-linux-i586.rpm

If the installation agreement appears, just press accept.

two。 Set the environment variable.

# vi / etc/profile

Join at the end

# set java environment

JAVA_HOME=/usr/java/jdk-1_5_0_02

CLASSPATH=.:$JAVA_HOME/lib.tools.jar

PATH=$JAVA_HOME/bin:$PATH

Export JAVA_HOME CLASSPATH PATH

Save exit.

To make JDK available to all users, you can do this:

Vi / etc/profile.d/java.sh

Enter the following in the new java.sh:

# set java environment

JAVA_HOME=/usr/java/jdk-1_5_0_02

CLASSPATH=.:$JAVA_HOME/lib/tools.jar

PATH=$JAVA_HOME/bin:$PATH

Export JAVA_HOME CLASSPATH PATH

Save exit and assign permissions to java.sh: chmod 755 / etc/profile.d/java.sh

3. Use the echo command at the terminal to check the setting of the environment variable.

# echo $JAVA_HOME

# echo $CLASSPATH

# echo $PATH

4. Check that JDK is installed successfully.

# java-version

If you see the JVM version and related information, the installation is successful!
