openjdk1.8部署

JDK安装

2021-03-03 小游戏cat采用的openjdk版本

openjdk 1.8.262.10版本

需要以下版本
个人建议用迅雷下载，不需要用wget方式.

下面是jdk rpm包不可或缺的，四个不能少.

yum 顺序按照下面方式即可.

java-1.8.0-openjdk-headless-1.8.0.262.b10-1.el7.x86_64

tzdata-java-2020a-1.el7.noarch

java-1.8.0-openjdk-devel-1.8.0.262.b10-1.el7.x86_64

java-1.8.0-openjdk-1.8.0.262.b10-1.el7.x86_64
