About Nginx 403 forbidden error directory index step on the pit of "/ xx / xx / xx /" is forbidden

Today, we are doing a Nginx share a directory server disk.

The difference is increased by two parameters

    server {
        listen xxx;
        server_name down.cdbaidu.com;

        location / {
         
        root  /Downloads/Dokcers/b1/downloads;
        ON autoindex;       # <---- culprit, adding this will no longer be 403 errors
        #index  index.php index.html;  

        # auth 
        auth_basic " Please the INPUT B1 password " ; # Set the encryption login prompt
        auth_basic_user_file / etc / nginx / xxx / . Htpasswd; # set encrypted account password file
       }

        # log
        access_log /Downloads/Dokcers/b1/web/access.log;
        error_log /Downloads/Dokcers/b1/web/error.log info ; # open this pattern has attention troubleshooting

        # IP access  
        the allow 192.168 . x.0 / 22 ; # IP segment limit landing
        deny all;
    }

 

In addition to the above, there are 403 errors. Need troubleshooting ideas

1. selinux

2. Under directory has no index.html file (if there is need to have a complete index index.html)

3. The rights issue
