1、下载安装包

[root@jenkins app]# uname -a                                                              Linux jenkins 4.18.0-80.7.2.el7.aarch64 #1 SMP Thu Sep 12 16:13:20 UTC 2019 aarch64 aarch64 aarch64 GNU/Linux 

这里是aarch64架构，所以下载jdk需要下载对应的，Java Downloads | Oracle

​

2、解压

tar -zxvf jdk-17_linux-aarch64_bin.tar.gz -C /app/

3、配置环境变量

vim /etc/profile

# shift + G到最后一行，o进行输入
export PATH=$JAVA_HOME/bin:$PATH 

source /etc/profile

4、验证

显示以下内容表示成功

[root@jenkins app]# java -version
