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）
