=====正文=====

我使用VPS的經驗比較有限，用過阿里雲、aws、vultr，現在比較推崇vultr，理由是按時計費合理，調用api創建/銷毀/重啟實例方便，每個實例可添加2個額外IP（適合爬蟲等），售後服務不錯。價格也可以，每月5刀那種配置能滿足不少場景需求了。

我現在是把它跟阿里雲配合用的，比如搞爬蟲時，阿里雲是調度、數據中心，vultr是提供資源幹活的。開始用vultr源起於某段時間搞爬蟲的痛點，各種被403/503，買了代理庫的代理信息，但用著很不爽，可用率比較低，能用的沒多久也down掉了。後來在知乎搜VPS用發現了vultr，開始試用。按小時計費，有比較完善的api，研究了下api用python寫了管理腳本，批量創建、銷毀實例十分方便，用起來實在太爽。跑過爬蟲的應該知道IP的重要性，vultr干這個效率很高。每個實例可添加2個額外IP，不過額外收費，且需額外配置。

機房連接速度方面，我用的北京聯通，一開始測了洛杉磯、日本的感覺日本的稍快些，用著也不錯，過了幾天開第二個賬號發現日本的各種連接問題，大致40%的實例創建後ping不通，開ticket跟工作人員溝通了很久，最終確認問題還是在我們這邊，美國的也有類似問題；再後來發現悉尼的連接穩定性很好，且速度不錯，用bypy往百度雲傳文件均速大約2M（不確定是我開的那台比較好還是普遍這樣，後來沒往百度雲傳過東西了），於是用api直接開了30台在悉尼，全部工作順利。上個圖：

分享幾個注意事項：

1、建第二個賬號後發現smtp網路被默認禁用了，開ticket確認了此事，工作人員主動給解封了，說是新政策，為了反垃圾郵件。

2、我的兩個賬號默認實例限制分別是5或者10，不太清楚為什麼不一樣，不過可以要求放寬限制，我的兩個現在分別是10和20，後面應該可以繼續提升；限制實例數量據說主要是出於安全目的（也可能跟我最開始用的是現金券有關）。

3、批量開實例前建議測試下網路連接，不同省市、不同運營商的網路差別可能挺大，到某地機房的具體線路可以用mtr查看下。

用腳本查詢開的實例信息：

分享我寫的python管理腳本，有意用的同學可以修改下用。我限制了只能在我阿里雲機器的網段使用api，所以調用了代理（阿里雲上的shadowsocks）訪問api，再就是新建的實例會運行賬號下的script腳本，腳本會完成環境配置、從阿里雲上用git把代碼clone下來、啟動核心程序等工作。
