liuhongdi@lhdpc:/usr/local/source$ xz -d node-v16.13.1-linux-x64.tar.xz
liuhongdi@lhdpc:/usr/local/source$ tar -xvf node-v16.13.1-linux-x64.tar

三，安装node

1，移动到安装目录

liuhongdi@lhdpc:/usr/local/source$ mv node-v16.13.1-linux-x64 /usr/local/soft/

2,创建符号链接，供直接从命令行访问无需输入路径

liuhongdi@lhdpc:/usr/local/source$ sudo ln -s /usr/local/soft/node-v16.13.1-linux-x64/bin/node /usr/local/bin/node
[sudo] liuhongdi 的密码：
liuhongdi@lhdpc:/usr/local/source$ sudo ln -s /usr/local/soft/node-v16.13.1-linux-x64/bin/npm /usr/local/bin/npm

3,查看效果:

liuhongdi@lhdpc:/usr/local/source$ node -v
v16.13.1
liuhongdi@lhdpc:/usr/local/source$ npm -v
8.1.2

四，配置npm使用国内源

1,查看npm的当前配置

liuhongdi@lhdpc:/usr/local/source$ npm config list
; node bin location = /usr/local/soft/node-v16.13.1-linux-x64/bin/node
; cwd = /usr/local/source
; HOME = /home/liuhongdi
; Run `npm config ls -l` to show all defaults.

2,设置npm使用淘宝的源

liuhongdi@lhdpc:/usr/local/source$ npm config set registry https://registry.npm.taobao.org

3,查看是否生效

liuhongdi@lhdpc:/usr/local/source$ npm config list
; "user" config from /home/liuhongdi/.npmrc
 
registry = "https://registry.npm.taobao.org/"
 
; node bin location = /usr/local/soft/node-v16.13.1-linux-x64/bin/node
; cwd = /usr/local/source
; HOME = /home/liuhongdi
; Run `npm config ls -l` to show all defaults.

五，npm升级npm自身

1,查看当前版本

liuhongdi@lhdpc:/usr/local/source$ npm -v

2,升级npm 

liuhongdi@lhdpc:/usr/local/source$ npm install -g npm
