本文提供了一步一步的指南，用于在CentOS系统上安装Java 1.8。首先，检查系统是否已有JDK安装，并卸载旧版本。然后，通过YUM命令查找并列出可用的Java 1.8+版本。接着，安装所有必需的JDK 1.8.0组件。最后，验证安装是否成功。

1.检查系统是否自带有jdk

[root@test ~]# rpm -qa |grep java
[root@test ~]# rpm -qa |grep jdk
[root@test ~]# 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@test ~]# rpm -e java

2.yum查找Java 1.8+

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