403 RHEL 7.4上nginx的禁止错误

Question

我已经在RHEL 7.4上安装并设置了nginx。 / web中的基本安装以及其中的所有内容都是默认的index.html。文件夹/文件的权限设置为755/644。配置如下：

server {
    listen       80;
    server_name  <address>;

    #charset koi8-r;

    #access_log  /var/opt/rh/rh-nginx18/log/nginx/host.access.log  main;

    location / {
        root /web;
        index  index.html;
    }

    # redirect server error pages to the static page /40x.html
    #
    error_page  404              /404.html;
    location = /40x.html {
        root   /opt/rh/rh-nginx18/root/usr/share/nginx/html;
    }

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /opt/rh/rh-nginx18/root/usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

无论如何，我得到403错误。似乎没什么特别突出的。有什么想法吗？
