+# linux 下 JDK 的安装
+
+
+
+**系统环境**：centos 7.6
+
+**JDK版本**：jdk 1.8.0_20
+
+
+
+## 安装步骤：
+
+
+
+#### 1. 下载jdk安装包
+
+在[官网](https://www.oracle.com/technetwork/java/javase/downloads/index.html)下载所需版本的jdk，上传至服务器对应位置。（这里我们下载的版本为[jdk1.8](https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html) ,上传至服务器的/usr/java/目录下）
+
+#### 2. 解压jdk-8u201-linux-x64.tar.gz安装包
+
+```shell
+[root@ java]# tar -zxvf jdk-8u201-linux-x64.tar.gz
+```
+
+#### 3. 设置环境变量
+
+```shell
+[root@ java]# vi /etc/profile
+```
+
+在文件末尾末尾添加：
+
+```shell
+export JAVA_HOME=/usr/java/jdk1.8.0_201  
+export JRE_HOME=${JAVA_HOME}/jre  
+export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib  
+export  PATH=${JAVA_HOME}/bin:$PATH
+```
+
+#### 4. 执行source命令,使得配置立即生效
+
+```shell
+[root@ java]# source /etc/profile
+```
+
+#### 5. 检查是否安装成功
+
+```shell
+[root@ java]# java -version
+```
+
+显示出对应的版本信息则代表安装成功。
+
+```shell
+java version "1.8.0_201"
+Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
+Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)
+
+```
