centos6 yum安装jdk1.8+

一、环境

Linux操作系统： centos6.9

安装jdk版本： jdk1.8+

 

二、安装步骤

1、 检查系统是否自带有jdk

[root@VM_0_11_centos ~]# rpm -qa |grep java
[root@VM_0_11_centos ~]# rpm -qa |grep jdk
[root@VM_0_11_centos ~]# rpm -qa |grep gcj

     如果有信息输出则需要卸载掉原来的jdk版本，用rpm -e ...  例如： 卸载掉java

[root@VM_0_11_centos ~]# rpm -e java

2、 yum查找 java 1.8+ 的信息 

[root@VM_0_11_centos ~]# yum list java-1.8*
