1. 下载JDK

cd /home/temp

wget https://download.oracle.com/otn/java/jdk/8u261-b12/a4634525489241b9a9e1aa73d9e118e6/jdk-8u261-linux-x64.tar.gz

2. 解压缩

mkdir -p /home/java

tar -zxvf /home/temp/jdk-8u261-linux-x64.tar.gz -C /home/java

3. 配置环境变量
   编辑 /etc/profile 文件，在文件末尾添加如下配置

#Java
JAVA_HOME=/home/java/jdk1.8.0_261

CLASSPATH=$JAVA_HOME/lib/

PATH=$PATH:$JAVA_HOME/bin

export PATH JAVA_HOME CLASSPATH

4. 使配置生效

source /etc/profile

5. 检查是否配置成功
