通过博文 Nginx初步优化 就已经了解了Nginx的基础概念，已经可以对Nginx进行初步的优化了，包括：Nginx平滑升级 、更改Nginx版本信息、Nginx虚拟主机配置、nginx配置文件中location选项的作用等等。本篇博文主要针对Nginx进行进一步的优化。 博文大纲： 一、Nginx配置反向代理 二、Nginx的proxy缓存使用 三、优化Nginx服务的压缩功能 一、Nginx配置反向代理 配置Nginx作为反向代理和负载均衡，同时利用其缓存功能，将静态页面在Nginx中缓存，以达到降低后端服务器连接数的目的并检查后端web服务器的检查状态。 如图： 环境需求： 一台Nginx服务器（Centos系统）IP地址：192.168.1.1； 两台httpd服务器（Centos系统）IP地址：192.168.1.2 192.168.1.3； 下载 Nginx软件包 安装Nginx： [root@localhost ~]# yum -y install gcc gcc-c++ make libtool zlib zlib-devel pcre pcre-devel openssl openssl-devel //如果安装系统时，是最小化安装，则需要安装以上依赖包 [root@localhost ~]# yum -y install pcre-devel zlib

I can drag the main window for the app, but the red/yellow/green window buttons are greyed out. And the DemoApp's menu is unclickable as well. This seems really strange to me, and I've been unable to figure it out. Examples of using event taps are few and far between, so any
