背景

今天服务器被重置拉，nodejs 环境不存在，特意安装下nodejs，一访问官网，妈呀，居然到20版本拉！就尝试安装下最新版本！

---

过程

$ cd /opt
$ curl -OL https://nodejs.org/dist/v20.10.0/node-v20.10.0-linux-x64.tar.gz
$ tar -zxvf node-v20.10.0-linux-x64.tar.gz -C /usr/local/
$ cd /usr/local/
$ mv node-v20.10.0-linux-x64/ nodejs
$ ln -s /usr/local/nodejs/bin/node /usr/local/bin/node
$ ln -s /usr/local/nodejs/bin/npm /usr/local/bin/npm

到这里nodejs 安装基本完成拉
