Linux 环境安装 Node与nginx_系统运维

概述Linux 环境安装使用 nvm 安装 Node wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash# 激活nvmsource ~/.nvm/nvm.sh# 安装nodenvm install node# 切换到该版本nvm use node 使用 nvm 管理 nod linux 环境安装使用 nvm 安装 Node

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash# 激活nvmsource ~/.nvm/nvm.sh# 安装nodenvm install node# 切换到该版本nvm use node

使用 nvm 管理 node 版本

# 安装某版本 比如 4.2.2nvm install 4.2.2# 列出远程服务器上所有可用版本nvm ls-remote# 在不同版本间切换nvm use 4.2.2#安装最新版 Nodenvm install node#切换到最新版nvm use node#列出已安装实例nvm ls#安装最新不稳定版本nvm install unstable

安装 Nginx
