Nginx Day one
安装
去nginx.org上下载最新的nginx源码包
./configure
make && make install
安装好后测试一下，先修改配置文件，在配置文件中设置服务器根目录的路径为博客的根目录：
root ...
启动nginx，在浏览器中输入localhost:80：
测试下性能
使用‘ab’工具来测试nginx的性能，关于这个工具可以读一下manual：
ab is a tool for benchmarking your Apache Hypertext Transfer Protocol (HTTP) server. It is designed to give you an impression of how your current Apache installation performs. This especially shows you how many requests per second your Apache installation is capable of serving.
➜ blog git:(master) ✗ ab -kc 1000 -n 10000 http://127.0.0.1:80/

请求博客的index.html10000次，同一时间concurrency设置为1000时，输出信息中显示完成10000个并发请求一共花费了0.59秒。
同样测试一下apache的性能：
当concurrency为1000时，直接崩掉

此时完成10000个请求共花费了5.577秒，将近是nginx服务器的10倍，相比较在并发量比较大时nginx的性能还是要远远好于apache的。
