运维 | 了解 nginx 配置中 root 与 alias 的区别 | nginx

  • 官方 root
Sets the root directory for requests, For example, with the following configuration

location /i/ {
    root /data/w3;
}

The /data/w3/i/top.gif file will be sent in response to the /i/top.gif request

  • 官方 alias
Defines a replacement for the specified location, For example, with the following configuration

location /i/ {
    alias /data/w3/images/;
}

on request of /i/top.gif, the file /data/w3/images/top.gif will be sent.

当访问 /i/top.gif 时,root 是去 /data/w3/i/top.gif 请求文件,alias 是去 /data/w3/images/top.gif请求,也就是说
root 响应路径:配置路径+完整访问路径(网站的location配置路径+静态文件)
alias 响应路径:配置路径+静态文件(去除location中配置的路径)
