概要

最近在宝塔上安装jdk，发现Oracle的java8自8u202版本后，做商业用途就要收费了。免费版本有：
OpenJDK（官方开源版）
Adoptium Temurin（最推荐）
Amazon Corretto
Zulu JDK
所以选择了Eclipse旗下的Adoptium Temurin。

技术细节

在阿里云上安装：

rpm --import https://packages.adoptium.net/artifactory/api/gpg/key/public
curl -o /etc/yum.repos.d/adoptium.repo \
https://packages.adoptium.net/artifactory/rpm/centos/7/x86_64/adoptium.repo

vim /etc/yum.repos.d/adoptium.repo
