# [centos7.0 下安装jdk1.8][centos7.0 _jdk1.8] #

centos7.0这里安装jdk1.8采用yum安装方式，非常简单。

1、查看yum库中jdk的版本

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div>
      1 
    </div></td> 
   <td> 
    <div> 
     <div> 
      <code>[root@localhost ~]# yum search java|grep jdk</code> 
     </div> 
    </div></td> 
  </tr> 
 </tbody> 
</table>

2、选择java-1.8.0安装

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div>
      1 
    </div></td> 
   <td> 
    <div> 
     <div> 
      <code>[root@localhost ~]# yum install java-1.8.0-openjdk*</code> 
     </div> 
    </div></td> 
  </tr> 
 </tbody> 
</table>

3、配置环境变量

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div>
      1 
    </div></td> 
   <td> 
    <div> 
     <div> 
      <code>[root@localhost ~]# vi /etc/profile</code> 
     </div> 
    </div></td> 
  </tr> 
 </tbody> 
</table>

这里jdk1.8.0的文件夹路径是/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.111-1.b15.el7\_2.x86\_64

添加如下内容，

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div>
      1 
    </div> 
    <div>
      2 
    </div> 
    <div>
      3 
    </div> 
    <div>
      4 
    </div> 
    <div>
      5 
    </div> 
    <div>
      6 
    </div></td> 
   <td> 
    <div> 
     <div> 
      <code>#set java environment</code> 
     </div> 
     <div> 
      <code>JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.111-1.b15.el7_2.x86_64</code> 
     </div> 
     <div> 
      <code>JRE_HOME=$JAVA_HOME/jre</code> 
     </div> 
     <div> 
      <code>CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib</code> 
     </div> 
     <div> 
      <code>PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin</code> 
     </div> 
     <div> 
      <code>export JAVA_HOME JRE_HOME CLASS_PATH PATH</code> 
     </div> 
    </div></td> 
  </tr> 
 </tbody> 
</table>

4、环境变量生效

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div>
      1 
    </div></td> 
   <td> 
    <div> 
     <div> 
      <code>[root@localhost ~]# source /etc/profile</code> 
     </div> 
    </div></td> 
  </tr> 
 </tbody> 
</table>

5、查看jdk是否安装成功

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div>
      1 
    </div></td> 
   <td> 
    <div> 
     <div> 
      <code>[root@localhost ~]# java -version</code> 
     </div> 
    </div></td> 
  </tr> 
 </tbody> 
</table>
