**（1）先下载好jdk（链接：下载jdk）**

**（2）在Linux上创建文件夹**

**在usr下的local中新建名称为java的文件夹或者直接放在local文件夹下的都行。**

**![70 1][]**

**（3）把下载好的jdk拖拽到local文件夹下。我是通过xftp工具上传**

**（4）.在/usr/local/java或/usr/local目录，执行tar -xzvf  jdk-8u171-linux-x64.tar.gz**

**（5）通过命令 vim /etc/profile 进入编辑页面**

**（6）配置jdk的环境变量，vim /etc/profile 进入编辑页面后，在此后边添加如下信息：**

export JAVA_HOME=/usr/local/jdk
              export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
              export PATH=$JAVA_HOME/bin:$PATH

**![20200721153614231.png][]**

**     通过按A或者i进入编辑模式，把上述信息拷贝到profile里，然后按esc，shift+: ，wq! 命令保存**

**（7）让profile文件生效**

> **            source /etc/profile**

**（8）安装是否成功**

**      javac -version 或者 javac。**

**![20200721152933557.png][]**

**以上表示没有此文件夹的权限，执行以下步骤：**

**chmod +x  后面跟  javac所在文件夹，我以上的截图是在（/usr/local/jdk/bin/javac）![20200721153447558.png][]**

**![20200721153501854.png][] **

**出现以上图示就是成功 **
