[Environment] Centos7 deployment server installation JDK

A. Download the JDK

With linux download, then why not make something always got a few K, can not use

Ever since, I have no patience with a direct window to download the (empty and then study how to use linux download, mind, then, do not read below)

Official website address: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Select the desired version download, you need to hook indentured radio, or you will find that does not give download

After completion point people will politely tell you to say thank you

Here, I downloaded the tar.gz format should be compressed, this problem does not tangle

II. Tar.gz files uploaded to the server

Here is ftp upload, ftp, please do not set up the venue and ftp server build tutorial

 

III. Installation archive (sounds strange)

tar -zxvf jdk-8u181-linux-x64.tar.gz

Here jdk-8u181-linux-x64.tar.gz I archive in the download window, remember to change the file name under their own

And then it is loaded ... loading ... loading completed ....

 

IV. Environment Configuration

open a file

vim /etc/profile

Filling them (although not the same style file, but according to plug it wants)

config path #jdk
JAVA_HOME = / usr / local / the Java / jdk1.8.0_181 / ( Note that remember their own JDK into the path of )
the CLASSPATH = $ JAVA_HOME / lib /
the PATH = $ the PATH: $ JAVA_HOME / bin
Export the PATH JAVA_HOME the CLASSPATH

Update Configuration

V. Check whether the installation is complete
