一、JDK下载地址

### --- jdk1.8.0_281软件包下载地址

~~~     地址：http://www.oracle.com/technetwork/java/javase/downloads/index.html

### --- 安装部署

[root@server14 ~]# tar -zxvf jdk-8u281-linux-x64.tar.gz 
[root@server14 ~]# mkdir -p /usr/local/java
[root@server14 ~]# mv jdk1.8.0_281/ /usr/local/java/

### --- 设置所有者

[root@server14 ~]# chown -R root:root /usr/local/java/

二、配置环境变量

### --- 配置系统环境变量

[root@server14 ~]# vim /etc/environment
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
export JAVA_HOME=/usr/local/java/jdk1.8.0_281
export JRE_HOME=/usr/local/java/jdk1.8.0_281/jre
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

### --- 配置用户环境变量

[root@server14 ~]# vim /etc/profile
if [ "$PS1" ]; then
  if [ "$BASH" ] && [ "$BASH" != "/bin/sh" ]; then
    # The file bash.bashrc already sets the default PS1.
    # PS1='\h:\w\$ '
    if [ -f /etc/bash.bashrc ]; then
      . /etc/bash.bashrc
    fi
  else
    if [ "`id -u`" -eq 0 ]; then
      PS1='# '
    else
      PS1='$ '
    fi
  fi
fi
export JAVA_HOME=/usr/local/java/jdk1.8.0_281
export JRE_HOME=/usr/local/java/jdk1.8.0_281/jre
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOME/bin
if [ -d /etc/profile.d ]; then
  for i in /etc/profile.d/*.sh; do
    if [ -r $i ]; then
      . $i
    fi
  done
  unset i
fi

### --- 使用户环境变量生效

[root@server14 ~]# source /etc/profile

三、测试是否安装成功

### --- 测试是否安装成功

[root@server14 ~]# java -version
java version "1.8.0_281"
