網站首頁目錄在/data/www
admin首頁在/data/backend/www/

該怎麼配才是對的呢?

Answer 1

因為你配置的路徑是符合 /admin/ url以/admin/開始的才請求/data/www/admin

你訪問xxxxx.com/admin 相當於匹配的還是第一個

   #网站首页
    location / {
        root   /data/www/;     #html;
        index  index.html index.htm;
    }

訪問xxxxx.com/admin/ 才匹配的是

    #后台工程配置
    location ^~/admin/ {
        alias   /data/backend/www/;
        index  index.html;
    }

另外, 你也可以改成兩個server，從根本上隔離網站首頁和網站管理端，也方便後面添加域名什麼的

Answer 2

你的nginx是用什麼用戶運行的？ /data/www/admin 的目錄權限又是什麼，檢查一下
