Nginx反向代理Demo

关于Nginx的基础理解,淘宝的文档已经介绍很清楚了：http://tengine.taobao.org/book/
以下记录些具体的使用流程，方便日后查看。

一. 整体配置步骤：

1. 安装Nginx。
   1. 安装依赖包，包括 pcre 以及 zlib 依赖。centos7的 root 权限下 yum list 搜索，再安装。
   2. 下载Nginx。./configure ---> make ---> make install.（安装成功看提示就知道安装在哪，一般在/usr/local/nginx）
   3. 访问 wget 127.0.0.1 即可看到安装成功。
2. 准备一个机子放Web应用，例如我的应用地址为 192.168.1.99.157:8081/springmvc。再准备一个机子（我的安装Nginx的机子的IP为192.168.199.176）安装上述的Nginx（其实你用同一个机子也是可以测试的，用不同的 端口当做不同的机子）
3. 在安装了Nginx的机子上修改nginx.conf主配置文件。例如如下的配置文件(测试版)：
