各位先進大家好
小弟在設定Nginx + PHP時
只設定root網站沒問題
用chrome可以正常顯示 http://www.xxx.xxx 首頁
但是想要在新增一個類似像Apache一樣一個Alias網站用這個url http://www.xxx.xxx/bbb/
可以連到phpmyadmin管理db
但是都會一直以下的出現Error

2024/01/16 07:03:36 [error] 10858#10858: *1 directory index of "/var/www/bbb" is forbidden, client: aaa.aaa.bbb.bbb,
server: cs99.org, request: "GET /phmadm/ HTTP/1.1", host: "aaa.aaa.bbb.bbb"

2024/01/16 07:10:30 [error] 10933#10933: *1 FastCGI sent in stderr: "Primary script unknown" while reading response

/unix:/run/php-fpm/www.sock:", host: "aaa.aaa.bbb.bbb"

以下是nginx的設定

server {
    listen       80;
    listen       [::]:80;
    server_name  xxx.xxx xxxweb.xxx.xxx aaa.aaa.bbb.bbb;
    root         /var/www/xxxweb;

    index index.php index.html;
    autoindex off;
    try_files $uri $uri/ /index.php?$args;

    access_log /var/log/nginx/xxxweb.access;
    error_log /var/log/nginx/xxxweb.error;

    location ~ \.php$ {
        include fastcgi_params;
        fastcgi_pass unix:/run/php-fpm/www.sock;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    location ~ /bbb/ {
        alias /var/www/bbb;
	index index.php;
   }

    location ~ ^/phmadm.+.php$ {
	root /var/www/bbb;
	fastcgi_pass 127.0.0.1:9000;
	fastcgi_index index.php;
	fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
	include fastcgi_params;
    }
}

請各位先進不吝指導
謝謝
