Statement: I am a Fedora8 Linux User. Assume that the current user is abin.

1. Download The jdk-6u4-Linux-i586.bin to www.sun.com, assuming it is downloaded to the current user directory;

2. Create the software Directory under/home/abin and copy the jdk-6u4-Linux-i586.bin to the software Directory;

3. find the terminal, go to/home/abin/software, Execute Command sh jdk-6u4-Linux-i586.bin, the screen will show some protocol files, one way press enter, at last will recognize you confirm installation, enter yes, press enter. Wait a moment ......, A jdk1.6.0 _ 04 folder is generated under/home/abin/software. This is the jdk installation directory.

Okay. Set the jdk environment variable as follows:

4. If it is only for the current user, go to the current user directory (/home/abin), edit the. bashrc file, and add the environment variable at the end, as shown below:

JAVA_HOME =/home/abin/software/jdk1.6.0 _ 04

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

PATH = $ JAVA_HOME/bin: $ PATH

Note: When setting environment variables, pay attention to the following points:

A) The first is the format of environment variables. previously set in windows to separate the paths with semicolons, and use colons in Linux;

B) Second, check whether there are any variables to be set in the system. If yes, add ": $ variable name" to the variable with the same name. For example, if the PATH variable exists in the system, you must write PATH = $ JAVA_HOME/bin: $ PATH when setting the PATH variable. Otherwise, the last set content will overwrite the previous content.

To check whether a variable with the same name exists in the system, run the echo command in the following format: echo $ PATH
