信创日志：银河麒麟V10 安装 国产JDK - Alibaba dragonwell

官方介绍，可以看看其适不适合自己的需求

Over the years, more than a billion lines of Java code have been written in Alibaba. While adopting OpenJDK to run these applications, we have found a need to customize it specifically for large-scale Java application deployments. Our customization has been well tested in our environment. We are now contributing some of our work into the Java community.

Alibaba Dragonwell, as a downstream version of OpenJDK, is the in-house OpenJDK implementation at Alibaba. It is optimized for online e-commerce, financial and logistics applications running on 100,000+ servers. Alibaba Dragonwell is the engine that runs these distributed Java applications in extreme scaling.

第一步：打开 官网 ，下载合适自己的版本。

第二步：解压缩包

使用如下命令

tar -xzvf Alibaba_Dragonwell_Extended_8.20.21_x64_linux.tar.gz

第三步：改名并配置环境变量

sudo mv  dragonwell-8.20.21 /opt/jdk8

编辑配置文件，可以是全局（/etc/profile）或者是用户的（'~/.bashrc'开头的文件）环境变量文件。
注意：要是非管理员编辑全局环境变量文件，需要在命令前添加sudo空格后执行
执行命令如下

vi .bashrc

添加内容如下：

export NGINX_HOME=/app/tengine
PATH=$PATH:$NGINX_HOME/sbin/nginx

保存文件后执行一下命令

source .bashrc
