This article introduces the relevant knowledge of "the installation method of JRE under the LINUX system". In the operation of the actual case, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

To run a JAVA program, you must install JAVA RUNTIME, that is, the environment you need to run it; we can get it by installing JRE or JDK; if we just apply but not develop, just download the JRE package; the JDK package also contains JRE;. This article takes the installation of JRE as an example; JRE also includes the JAVA plug-in needed by the browser.

Download JRE

Http://ftp.isu.edu.tw

Download the corresponding version according to your own machine. My machine is a 32-bit X86, so you can only download jre-1_5_0_04-linux-i586.bin; in the linux32 directory. If you are an X86-64-bit machine, download the relative

II. Decompression and configuration

1. Release the package

[root@localhost sunjava] # ls

Jre-1_5_0_04-linux-i586.bin

[root@localhost sunjava] # sh jre-1_5_0_04-linux-i586.bin

Do you agree to the above license terms? [yes or no] yes

[root@localhost sunjava] # ls

Jre1.5.0_04 jre-1_5_0_04-linux-i586.bin

2. Configure JRE

1) move the jre1.5.0_04 directory to the / usr/lib directory

[root@localhost sunjava] # mv jre1.5.0_04 / usr/lib/jre154

2) configure environment variables

Add three lines to the. bashrc of the current user, as follows:

JAVA_HOME=/usr/lib/jre154

JAVA_BIN=/usr/lib/jre154/bin

Export JAVA_HOME JAVA_BIN

You can edit .bashrc files with gedit or vi

[root@localhost sunjava] # gedit ~ / .bashrc

[root@localhost sunjava] # vi ~ / .bashrc

3) add a font simsun.ttf

Create a directory fallback in / usr/lib/jre154/lib/fonts, then copy the font simsun.ttf to this directory, or copy simsun.ttc to simsun.ttf, and then put it in this directory

[root@localhost ~] # mkdir / usr/lib/jre154/lib/fonts/fallback

4) install java plugins; enable browsers to support java programs

For example, if I use a firefox browser, build a link for libjavaplugin_oji.so to the plugins directory in the directory corresponding to firefox, and other browsers will do the same; [root@localhost plugins] # cd / usr/lib/firefox-1.0.6/plugins/

[root@localhost plugins] # ln-s / usr/lib/jre154/plugin/i386/ns7/libjavaplugin_oji.so.

5) call the JAVA console

[beinan@localhost ~] # / usr/lib/jre154/bin/ControlPanel
