nginx配置root和alias的区别

请求资源的URL：

http://127.0.0.1/storeadmin/css/jquery.Jcrop.css

实际在机器上的地址：

/users/apple/git_local/YAE/src/storeadmin/static/css/jquery.Jcrop.css

一开始nginx配置成：

location /storeadmin {
    root    /users/apple/git_local/YAE/src/storeadmin/static;
}

结果404错误，错误日志信息：

open() "/users/apple/git_local/YAE/src/storeadmin/static/storeadmin/css/jquery.Jcrop.css" failed (2: No such file or directory)

需要改为alias：

location /storeadmin {
    alias    /users/apple/git_local/YAE/src/storeadmin/static;
}

区别在于，在location后面配置的路径，在root里不会被丢弃，而在alias会丢弃掉
