安装JDK并配置环境变量
1.查看JDK版本信息java -version
根据需求，把openjdk替换成oraclejdk

如下图，显示java version 说明oraclejdk已经安装好了

2.下载oraclejdk安装包
官网 - 历史版本下载地址：http://www.oracle.com/technetwork/java/javase/archive-139210.html
下载正确的安装包

创建目录
mkdir -p /home/local/java
进入目录
cd /home/local/java
通过rz命令将文件上传到该目录

解压jdk压缩包
tar -zxvf jdk-8u271-linux-x64.tar.gz
配置环境变量
vim /etc/profile
将如下命令粘到末尾

注意：home/local/java/jdk1.8.0_45就是你自己的jdk目录
然后保存退出
重新加载配置文件
source /etc/profile
4.验证安装情况
输入 java -version

如图安装完毕
5.安装完毕启动jenkins报错

解决
which java
找到java的安装路径

把which里面找到的java路径加在这里，保存退出
