最近买VPS上瘾了,这次看到32MB的VPS,毫不犹豫地下手了,还配套买了个域名32mb.cn。

不要怀疑32MB内存的VPS不能建站哦。 eg:http://32mb.org

这次的目标就是山寨一个32mb.org。

主机商是CLoudShards,一家很新的主机商,

这货的购买链接:https://www.cloudshards .com/aff.php?a=add&aff=043&pid=123(心动的同学使用我的Aff购买吧) 已经倒闭了

小结

1、可能有人会说这是用钱买罪受,是,我就是闲的蛋疼,怎么着。

2、这样袖珍的VPS用于学习真心不错,倘若我能用好这32MB的VPS,Linux我算是入门了。

3、用于建站和卖SSH,VPN的同学请不要关注这款VPS。
