构建nodejs环境

　　总想留下点东西，不负年华！

00、download

release
https://nodejs.org/dist/      //all release

example

https://nodejs.org/dist/v6.10.3/node-v6.10.3-linux-x64.tar.xz

tar Jxf node-v6.10.3-linux-x64.tar.xz && mv node-v6.10.3-linux-x64 node-v6 && mv node-v6 /usr/local/

vi /etc/profile    ###配置全局环境变量，真实的环境建议配置用户级别的变量，防止不可写
export NODE_HOME="/usr/local/node-v6"
export PATH=$NODE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$NODE_HOME/lib:$LD_LIBRARY_PATH

source /etc/profile

#查看版本
node -v
npm -v

01、配置代理及npm源

//配置代理
内网访问外网资源
npm config set proxy=http://127.0.0.1:8008
npm config set https-proxy http://127.0.0.1:8008 //https-->http
npm config set registry=http://registry.npm.taobao.org //注册npm

代理用户名和密码
npm config set proxy http://username:password@server:port
npm confit set https-proxy http://username:password@server:port

取消代理
npm config delete proxy
npm config delete https-proxy

临时使用
npm --registry https://registry.npm.taobao.org install express
持久使用
npm config set registry https://registry.npm.taobao.org
验证
npm config get registry
npm install forever -g
