一、下載安裝包
# 安裝包的地址可在這里查看：https://npm.taobao.org/mirrors/node
# 也可以在官網自行查找：https://nodejs.org
wget http://npm.taobao.org/mirrors/node/latest-v14.x/node-v14.0.0-linux-x64.tar.xz
二、解壓
# 壓縮包解壓即可使用，解壓位置請自行選擇
# 我這里選擇：/usr/local
cd /usr/local
tar -xvf node-v14.0.0-linux-x64.tar.xz
rm -rf node-v14.0.0-linux-x64.tar.xz
三、設置快捷命令
# 先備份一下之前的，沒有可以忽略
mv /usr/local/bin/node /usr/local/bin/node.bak
mv /usr/local/bin/npm /usr/local/bin/npm.bak
# 定義軟連接到bin下，即可在任何地方使用node
ln -s /usr/local/node-v14.0.0-linux-x64/bin/node /usr/local/bin/node
ln -s /usr/local/node-v14.0.0-linux-x64/bin/npm /usr/local/bin/npm
四、測試
[root@localhost bin]# node
Welcome to Node.js v14.0.0.
Type ".help" for more information.
>
[root@localhost bin]# npm

Config info can be viewed via: npm help config
npm@6.14.4 /usr/local/node-v14.0.0-linux-x64/lib/node_modules/npm
五、加速npm
# 安裝淘寶的cnpm代替npm
npm install -g cnpm --registry=https://registry.npm.taobao.org
# 查看版本
[root@localhost /]# cnpm -v
cnpm@6.1.1 (/usr/local/lib/node_modules/cnpm/lib/parse_argv.js)
npm@6.14.2 (/usr/local/lib/node_modules/cnpm/node_modules/npm/lib/npm.js)
node@14.0.0 (/usr/local/node-v14.0.0-linux-x64/bin/node)
npminstall@3.27.0 (/usr/local/lib/node_modules/cnpm/node_modules/npminstall/lib/index.js)
prefix=/usr/local/node-v14.0.0-linux-x64
linux x64 3.10.0-1062.9.1.el7.x86_64
registry=https://r.npm.taobao.org
六、版本管理
# nodejs 使用 n 模塊進行nodejs的版本
# 我們首先安裝n模塊
cnpm install -g n
# 列出所有的版本，鍵盤上下鍵可切換版本
n
# 安裝最新版本
n latest
# 安裝最新穩定版
n stable
# 安裝最新長期支持版本
n lts
