32MB内存感觉怎么样? Cloudshards超小内存VPS体验

PS:这家已经倒闭了

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,

略有丢包的现象,Ping值200左右跟Urpad的洛杉矶差不多,哦LA也是加州的。

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。

    My blog never survive over 3 months. I like to try all the minimum plan which I found from LEB and WHT. If there any opportunity we can be friends, that awesome!

    PS: Sorry for that no permission Linux system with no Chinese input.

    1. Ryan
      @Molinxx

      OK,I misunderstood with my poor english.
      Chinese is not required.

        @Ryan

        之前在学校实验室机房,机器都是Ubuntu,没给权限所以没法装输入法,所以只能凑合打英文了~
        (逃)~待我重建好博客加个友链可否?
        另外问一下,这个俄罗斯主机是多少钱买的?我循着IP找过去了,发现价格并不便宜……现在手头有一个vStoike的俄罗斯VPS,有什么可以在俄罗斯VPS上折腾的东西咩?

        1. Ryan
          @Molinxx

          可以啊。
          hostlix.ru买的 上家adman也不贵吧20rmb一个月。
          俄罗斯的vps可以考虑做大人站

    2. Ryan
      @Molinxx

      'Some Chinese Please' just because this is a chinese blog.
      I think I should find a better way to detect spam comments beacause this cannot stop robots effictive.

  2. TS吴小强

    主页前面系统状态是怎么做上去的

    1. Ryan
      @TS吴小强

      读取/proc/meminfo 和 uptime 然后正则

  3. ★Extreme★

    恐怕只有OpenVZ能占这么少资源了……

    1. Ryan
      @★Extreme★

      的确如此

  4. 沫沫坑

    32M怎么跑sql=。=..

    1. Ryan
      @沫沫坑

      mysql的話當然不行,但是sqlite足夠了

  5. opoo

    32MB,有点小牛。偶的静态博客还跑在512M的VPS上,岂不是有点浪费。

    1. Ryan
      @opoo

      不浪費,我這是作死而已

  6. 免费部落

    感觉还是太小了!

  7. FROYO

    太能折腾了,这么小内存居然也能跑起来

  8. 木子

    还有比这小内存的vps么、

    1. Ryan
      @木子

      應該木有了

  9. 免费资源部落

    一年是7美元左右,还可以。

    1. Ryan
      @免费资源部落

      我準備試試跑wordpress看能不能撐過webbench

        @Ryan

        要是一年1美元就好了..

        1. Ryan
          @qq374594

          额见过最便宜4美刀一年的

          1. qq374594
            @Ryan

            感觉还是不值...

            1. Ryan
              @qq374594

              额,我感觉这32的挺值得,比h1f爽多了

              1. qq374594
                @Ryan

                额 h1f至今没给我开通
