• YAPI是一个高效、易用、功能强大的API管理平台旨在为开发、产品、测试人员提供更优雅的接口管理服务，这是官网上面说的
• 安装Node，参考 Centos下安装node
• 安装mongodb, 参考 mongodb的安装和常用配置项的含义
• 安装 yapi “npm install -g yapi-cli –registry https://registry.npm.taobao.org”
• “yapi server” 启动yapi配置向导，包括yapi的安装位置，mongodb数据库等信息
• “npm install pm2 -g”安装pm2来管理yapi，可以方便的停止 启动等操作
• 启动yapi “pm2 start /your_install_path/vendors/server/app.js –name yapi”,默认的启动端口是3000；登录的默认用户名是：admin@admin.com ； 默认密码：ymfe.org

#!/bin/bash
cd /opt && wget https://nodejs.org/dist/v12.19.0/node-v12.19.0-linux-x64.tar.xz
xz -d node-v12.19.0-linux-x64.tar.xz && tar xvf node-v12.19.0-linux-x64.tar
mv node-v10.16.0-linux-x64 node
chown -R root:root /opt/node
ln -s /opt/node/bin/node /usr/bin/node
ln -s /opt/node/bin/npm /usr/bin/npm
[ -f /opt/node-v12.19.0-linux-x64.tar.xz ] && rm /opt/node-v12.19.0-linux-x64.tar.xz -rf
