Linux JDK Installation Steps

1. Log in to Linux and switch to the root user

Su Root gets root user rights, the current working directory is unchanged (requires root password)


Or


Sudo-i does not require the root password to switch directly to root (requires the current user password)

2. Create the Java installation directory in the USR directory

Cd/usr


mkdir Java

3. Copy the jdk-8u60-linux-x64.tar.gz to the Java directory

cp/mnt/hgfs/linux/jdk-8u60-linux-x64.tar.gz/usr/java/

4. Unzip the JDK to the current directory

TAR-ZXVF jdk-8u60-linux-x64.tar.gz


Get folder jdk1.8.0_60

5. Installation completed for him to create a link to save the directory length

(I don't use this step)
Ln-s/usr/java/jdk1.8.0_60//USR/JDK

6. Edit the configuration file, configure environment variables

Vim/etc/profile


Add the following: Java_home according to the actual directory to
Java_home=/usr/java/jdk1.8.0_60
Classpath= $JAVA _home/lib/
Path= $PATH: $JAVA _home/bin
Export PATH java_home CLASSPATH

7. Restart the machine or execute the command: Source/etc/profile

sudo shutdown-r now

8. View installation Status

Java-version


Java Version "1.8.0_60"
Java (TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot (TM) Client VM (build 25.60-b23, Mixed mode)
