不能打开本地页面的话，重新安装nginx可以解决，已经三次了！
要先kill -9 进程号，卸载brew uninstall nginx，然后再安装，再sudo nginx，然后根据提示，创建一个文件夹和一个文件就能用了。
不用重新装，这次先ps -ef|grep nginx接下来kill -9 进程号(第二列)，然后lsof -i:xxx 确保进程杀掉，最后sudo nginx
a.上面博客说了在Linux中安装nginx。博文地址为：www.cnblogs.com/hanyinglong…
b.当Nginx安装完毕后，会有相应的安装目录，安装目录里的nginx.confg为nginx的主配置文件，nginx主配置文件分为4部分，main(全局配置)、server(主机配置)、upstream(负载均衡服务器设置)以及location(URL匹配特定位置的设置),这四者的关系是：server继承main,location继承server,upstream既不会继承其它设置也不会被继承。
c.Nginx是一个代理服务器，一般情况下，网站是不能部署在Nginx下的，比如用Java开发的JavaWeb程序，我们部署在tomcat下，然后使用Nginx代理将网址指向tomcat即可。
3.Nginx代理网站
a.我在tomcat下部署了一个javaweb项目，tomcat安装的服务器IP为：192.168.37.136，部署的项目在tomcat下的访问地址为：http://192.168.37.136:8080/lywh/
b.我在IP为192.168.37.133的服务器下面安装成功了Nginx。
c.那怎么样将tomcat下部署的网站使用Nginx代理呢？，修改Nginx的配置文件，修改命令：vim /usr/local/nginx/conf/nginx.conf
