VPS出租系统的主要功能模块有哪些？

VPS出租系统如何搭建？从零开始构建VPS租赁平台的完整指南

# 服务器基础配置检查
$ lscpu                    # 查看CPU信息
$ free -h                  # 查看内存使用情况
$ df -h                    # 查看磁盘空间
$ ip addr show            # 查看网络接口配置

# KVM环境安装
$ yum install -y qemu-kvm libvirt virt-install bridge-utils
$ systemctl enable libvirtd
$ systemctl start libvirtd
创建虚拟机模板
$ virt-install --name template-vm --ram 2048 --vcpus 2 \
--disk path=/var/lib/libvirt/images/template.qcow2,size=20 \
--os-type linux --os-variant centos7.0 --network bridge=br0 \
--graphics none --console pty,targettype=serial

步骤三：控制面板开发

• 前端框架：React或Vue.js
• 后端语言：Python Flask或PHP Laravel
• 数据库：MySQL或PostgreSQL

# Flask后端示例 - VPS管理API
from flask import Flask, jsonify, request
import libvirt
app = Flask(name)
@app.route('/api/vps/create', methods=['POST'])
def createvps():
    """创建新的VPS实例"""
    conn = libvirt.open('qemu:///system')
    # 解析用户请求参数
    userdata = request.json
    # 执行VPS创建逻辑
    return jsonify({'status': 'success', 'vpsid': 'vm123'})
@app.route('/api/vps//status')
def getvpsstatus(vpsid):
    """获取VPS状态信息"""
    return jsonify({'status': 'running', 'cpuusage': '45%'})

-- 数据库表结构设计
CREATE TABLE pricingplans (
    id INT AUTOINCREMENT PRIMARY KEY,
    name VARCHAR(100) NOT NULL,
    cpucores INT NOT NULL,
    memorymb INT NOT NULL,
    storagegb INT NOT NULL,
    bandwidthgb INT NOT NULL,
    monthlyprice DECIMAL(10,2) NOT NULL,
    createdat TIMESTAMP DEFAULT CURRENTTIMESTAMP
);
CREATE TABLE usersubscriptions (
    id INT AUTOINCREMENT PRIMARY KEY,
    userid INT NOT NULL,
    planid INT NOT NULL,
    status ENUM('active', 'suspended', 'cancelled'),
    nextbillingdate DATE,
    FOREIGN KEY (userid) REFERENCES users(id),
    FOREIGN KEY (planid) REFERENCES pricingplans(id)
);
