nginx常用配置与操作

rewrite有rewrite日志可以打开!
# last表示rewrite之后还会重新请求

rewrite  ^(/download/.*)/media/(.*)\..*$  $1/mp3/$2.mp3  last;

# break则表示只在location中rewrite后停止，并退出

rewrite  ^(/download/.*)/audio/(.*)\..*$  $1/mp3/$2.ra   break;

# !感叹号是取反，没有匹配的意思

location  = / {                                                                                                                                       
  # matches the query / only.                                                      
  [ configuration A ]-                                                             
}                                                                                  
location  / {                                                                      
  # matches any query, since all queries begin with /, but regular                 
  # expressions and any longer conventional blocks will be                         
  # matched first.                                                                 
  [ configuration B ]-                                                             
}                                                                                  
location ^~ /images/ {
  # 优先匹配并会停止匹配                                                             
  # matches any query beginning with /images/ and halts searching,                 
  # so regular expressions will not be checked.                                    
  [ configuration C ]-                                                             
}                                                                                  
location ~* \.(gif|jpg|jpeg)$ { 
  # 不区分大小写匹配                                                   
  # matches any request ending in gif, jpg, or jpeg. However, all                  
  # requests to the /images/ directory will be handled by                          
  # Configuration C.---                                                            
  [ configuration D ]-                                                             
}

配置/wx/目录的访问到另一个port

    location /wx/ {
        rewrite /wx(.*) $1 break;
        proxy_pass http://127.0.0.1:8200;
        proxy_redirect off;
        proxy_set_header Host $host;
    }
