哈哈哈。百度搜 CACA代理，真给面子。第一名和第二名都是我的。

GOOGLE也差不多。

真可爱。今天晚上刚好和朋友出去吃饭，晚了点回来，一回来，就收到几个人Q,说网站挂了。。连我自己博客都打不开了。5555
我那个心急呀。要上去看，可是，，宽带帐号又有问题，还上不了网。用别人的无线，那掉包率非常的高啊。

连上网，看了80正常，重启了nginx服务，还是不见好。心急下，直接重启了服务器。唉。保持了200多天没重启的记录，就给清零了。重启后，恢复正常了。想到原因有可能是MYSQL挂了。没再去查啥了。可没几分钟又再次打不开了。。
查看日志 。。哈哈哈哈哈哈哈。。。是空间满了。。。。。。。。。。。。。。。。。。。。。。。。。。哈哈哈。nginx错误日志文件居然有30G了。哈哈。。罪魁祸首是百度！！！！以前一个站目录下放了MP3..结果给百度收着了。。当时服务器流量给这些下载耗光。痛苦了好一阵子。。

工作原理：
　　带有虚拟技术的处理器具有额外的指令集，叫做Virtual Machine Extensions，简称VMX。VMX给CPU带来了10个新的虚拟专用指令：VMPTRLD, VMPTRST, VMCLEAR, VMREAD, VMWRITE, VMCALL, VMLAUCH, VMRESUME, VMXOFF and VMXON。
在虚拟状态下有两种工作模式：root操作和非root操作。通常只有虚拟操作软件——Virtual Machine Monitor (VMM)能够运行在root操作模式下，而操作系统在虚拟机的顶层运行在非root操作模式下。运行在虚拟机顶层的软件同时也叫做“guest software”。

　　要进入虚拟模式，VMM需要执行VMXON指令来调入VMM软件，VMM软件使用VMLAUNCH指令来进入每一个虚拟机，使用VMRESUME指令来退出。如果想要退出虚拟模式，可以使用VMM运行VMXOFF指令。在图中的每个guest系统可以是不同的操作系统，同时运行自身的软件。
BIOS里面打开VT功能

最近工作变动，找房，搬东西，熟悉环境，折腾了好几天。现在总算好些了。。缓缓。明天去肇庆。。。

wordpress 3.1中文怎么还没出来。。提示升级好久了。也没中文出现。。。BS.。。这次效率真慢。。。

一晚上搞了几家WEP.不容易啊。。用本本自带的无线网卡，那个信号小的不行。弄上卡王，满格，牛B。终于可以上网了。
WPA太难搞了，明天去找弄个大字典。。慢慢玩～
