很多人搭个博客，要么买大了浪费、要么买小了卡。这篇给你一份「够用不浪费」的选机清单。
配置基线：1 核 1G 就能跑 WordPress
- 个人博客 / 小站（日访问几百以内）：1 核 1G、20G 硬盘足够跑 WordPress + 数据库。
- 访问量上来了 / 装插件多：升到 2 核 2G，加个缓存（Redis / 页面缓存）比堆配置更管用。
- 硬盘：选 NVMe / SSD，博客几乎不吃硬盘，20–40G 绰绰有余。
线路：面向谁，就优化谁
- 读者主要在国内：选三网回程好的（CN2 GIA / CMIN2 / 9929），打开快、不卡。
- 读者在海外 / 不在乎国内速度：普通线路就行，省钱。
不确定线路真假？用 Ping 测速 实测延迟，或看我们的 三网实测数据。
4 个常见坑
- 买高配但没缓存：博客慢多半是没开缓存，不是配置低。先装缓存再升配置。
- 忽略备份：便宜机说没就没，博客一定要定期备份（数据库 + 文件）。
- 流量算错：博客流量小，但图多 / 有下载就要算清月流量。
- 年付图便宜结果厂商跑路：小厂别一次付太久，先月付 / 季付观察稳定性。
先看库存，别原价买
适合建站的 1G / 2G 小鸡经常有特价补货。盯 实时库存，等补货比原价买省一半。
Many people setting up a blog either overbuy and waste money, or underbuy and end up with a sluggish site. Here’s a “just enough, nothing wasted” checklist for picking the right machine.
Baseline Specs: 1 Core / 1 GB RAM Is Enough to Run WordPress
- Personal blog / small site (a few hundred daily visitors): 1 core, 1 GB RAM, 20 GB disk is plenty to run WordPress + a database.
- Growing traffic / lots of plugins: Step up to 2 cores / 2 GB RAM and add caching (Redis or a page cache plugin) — that beats throwing hardware at the problem.
- Storage: Pick NVMe / SSD. Blogs are barely disk-intensive; 20–40 GB is more than enough.
Network Line: Optimize for Your Audience
- Readers mainly in China: Choose a VPS with a strong return route for China’s three carriers (CN2 GIA / CMIN2 / 9929). Pages load fast with no lag.
- Overseas readers / don’t care about China speed: A standard line works fine and saves money.
Not sure whether a line is legit? Run a real latency test with the Ping Speed Test, or check our three-carrier benchmark data.
4 Common Mistakes to Avoid
- Buying high-spec hardware without enabling caching: A slow blog is almost always a caching problem, not an underpowered server. Set up caching before upgrading specs.
- Skipping backups: Cheap VPS providers can disappear without warning. Always back up your blog regularly (database + files).
- Miscalculating bandwidth: Blog traffic is light, but lots of images or downloadable files can burn through your monthly quota fast — do the math first.
- Locking into long annual plans with small providers: Don’t prepay too far ahead with unknown providers. Start month-to-month or quarterly to gauge stability.
Check Stock First — Don’t Pay Full Price
1 GB / 2 GB VPS units suited for hosting often go on sale during restocks. Watch the real-time stock monitor — waiting for a restock can cut the price in half versus buying at list price.
