nginx下载

正向代理，客户端不想让服务器知道客户端的ip，所以让代理服务器去访问，再返回给客户端。 反向代理，服务器不想客户端知道是哪个服务器响应的，所以让代理服务器去分配，让空闲的服务器去响应。

nginx 基本命令

解压，双击双击nginx.exe启动

cmd 命令启动start nginx

• nginx -t 检查配合是否正确
• nginx -s quit/nginx -s stop 关闭
• nginx -s reload 重新加载nginx配置

location 的匹配规则

共四种方式

location[ = | ~ | ~* | ^~ ] url {

}

• = ：精确匹配，用于不含正则表达式的url前，要求字符串与url严格匹配，完全相等时，才能停止向下搜索并处理请求
• ^~：用于不含正则表达式的url前，要求ngin服务器找到表示url和字符串匹配度最高的location后，立即使用此location处理请求，而不再匹配
• ~ ：最佳匹配，用于表示url包含正则表达式，并且区分大小写。
• ~*：与~一样，只是不区分大小写

如果 url 包含正则表达式，则不需要 ~ 作为开头表示 nginx的匹配具有优先顺序，一旦匹配上就会立马退出，不再进行向下匹配
