下载安装
#wget https://openresty.org/download/ngx_openresty-1.7.10.1.tar.gz
#tar xf ngx_openresty-1.7.10.1.tar.gz
#cd ngx_openresty-1.7.10.1
#./configure --with-luajit
#make && make install

【location】
(1)=/ 和 /
  location = / {
      [configure A]
       }


  location / {
      [configure B]
        }


 #curl  http://localhost/ 匹配B
 分析:本来精确匹配应该为A,但当访问http://localhost/时,默认访问网址为http://localhost/index.html,所以匹配为B


 (2)=/index.html 和 /
  location = /index.html {
      [configure A]
       }


  location / {
      [configure B]
        }
 #curl  http://localhost/ 匹配A


(3)/xixi/ 与 ^~ /xixi/
    location /xixi/ {
      [configure A]
     }


   location ^~ /xixi/ {
      [configure B]
      }


  报错:
  nginx: [emerg] duplicate location "/xixi/" in  /usr/local/openresty/nginx/conf/nginx.conf:58
 分析:/xixi/与^~ /xixi/都属于普通字符匹配,属于重复配置




(4)~ /xixi/ 与 ^~ /xixi/
   location ~ /xixi/ {
      [configure A]
      }
 
  location ^~ /xixi/ {
      [configure B]
     }
  #curl  http://localhost/xixi/  匹配B
 分析:^~ /xixi/优先级大于正则 ~ /xixi/


  #curl  http://localhost/xixi
  报错:404 Not Found
  分析:错误日志显示xixi文件不存在
  # tail -n5 logs/error.log
   2017/02/17 23:19:52 [error] 9732#0: *118 open() "/usr/local/openresty/nginx/html/haha/xixi" failed (2: No such file or directory), client: 127.0.0.1, server: 192.168.204.131, request: "GET /xixi HTTP/1.1", host: "localhost"


 (5)~ /xixi/ 与  /xixi/
   location  /xixi/ {
      [configure A]
      }
 
   location ~ /xixi/ {
      [configure B]
     }   
  #curl  http://localhost/xixi/  匹配B
  分析: ~/xixi/ 优先 /xixi/
