中文(快速上手:创建 UHost 云主机)
本文将帮助你在 FEB CLOUD CORE 中快速创建一台 UHost 云主机,并完成基础联网与登录准备。
前置条件
- 已注册并登录 FEB CLOUD CORE 控制台
- 账号余额充足(如需)
- 已规划主机用途(Web/API/应用等)与所在地域
步骤 1:选择地域与可用区
- 建议选择距离用户更近的地域,以获得更低时延
- 若有多可用区,生产环境建议按可用区做容灾规划
步骤 2:选择镜像与规格
- 镜像:Linux(Ubuntu/CentOS 等)适合服务器应用;Windows 适合图形化/特定软件依赖
- 规格:从小规格起步,后续按业务压力扩容
- 系统盘/数据盘:建议系统盘放 OS,数据盘放业务数据(便于独立扩容/迁移)
步骤 3:配置网络(UVPC / 子网)
- 生产建议使用 UVPC 私有网络,便于安全隔离与内网互通
- 规划网段时避免与本地 IDC/办公网冲突(如后续要打通专线/VPN)
步骤 4:安全访问(SSH/密码/密钥 + 安全组)
- Linux 推荐使用 SSH Key 登录;Windows 使用强密码并限制来源 IP
- 安全组/防火墙仅开放必要端口(如 22/80/443),并尽量限制来源
步骤 5:公网访问(EIP)
- 如需公网访问,为主机绑定 EIP 弹性公网 IP
- 建议业务对外统一用域名,并为 Web 站点配置 HTTPS(USSL)
验证与排错
- 无法登录:检查安全组是否放行 22/3389、登录方式是否正确
- 无法访问网站:检查 80/443、应用是否监听、是否绑定 EIP
- 网络不通:检查 UVPC 路由/子网、是否存在重复网段冲突
English (Quick Start: Create a UHost VM)
This guide helps you quickly create a UHost VM in FEB CLOUD CORE and complete basic networking and access setup.
Prerequisites
- You can sign in to the FEB CLOUD CORE console
- Sufficient account balance (if required)
- Basic plan for region and workload (web/API/app)
Step 1: Choose Region & Zone
- Pick a region close to your users for lower latency
- For production, consider multi-zone design for resilience
Step 2: Select Image & Instance Size
- Image: Linux for most server workloads; Windows for GUI/specific dependencies
- Size: start small and scale up as load grows
- Disks: keep OS and data separated when possible
Step 3: Configure Networking (UVPC/Subnet)
- Use UVPC for isolation and private connectivity
- Avoid CIDR conflicts with on-prem networks if you plan VPN/direct connect later
Step 4: Secure Access (SSH/Password/Key + Security Group)
- Linux: prefer SSH keys; Windows: strong password and restricted source IPs
- Only open required ports (e.g., 22/80/443) and restrict sources when possible
Step 5: Public Access (EIP)
- Bind an EIP if public access is required
- Use domains and enable HTTPS for web services (USSL)
Validation & Troubleshooting
- Login fails: verify security group ports and credentials/keys
- Website unreachable: verify 80/443, app listener, and EIP binding
- Network issues: check UVPC routes/subnet and CIDR conflicts
