    1,nginx配置文件:

    user www-data;
    worker_processes auto;
    pid /run/nginx.pid;
    
    events {
        worker_connections 768;
        # multi_accept on;
    }
    
    http {
    
        ##
        # Basic Settings
        ##
    
        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;
        # server_tokens off;
    
        # server_names_hash_bucket_size 64;
        # server_name_in_redirect off;
    
        include /etc/nginx/mime.types;
        default_type application/octet-stream;
    
        ##
        # SSL Settings
        ##
    
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
        ssl_prefer_server_ciphers on;
    
        ##
        # Logging Settings
        ##
    
        access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;
    
        ##
        # Gzip Settings
        ##
    
        gzip on;
        gzip_disable "msie6";
    
        # gzip_vary on;
        # gzip_proxied any;
        # gzip_comp_level 6;
        # gzip_buffers 16 8k;
        # gzip_http_version 1.1;
        # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;
    
        ##
        # Virtual Host Configs
        ##
    
        server {
            listen 80;
            server_name localhost;
            root /var/www/html;
            index index.html index.html index.php;
    
            location ~ \.php$ {
                root /var/www/html;
                fastcgi_index index.php;
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                fastcgi_intercept_errors on;
                include fastcgi_params;
            }
    
            location = /favicon.ico {
                log_not_found off;
            }
        }
    
        include /etc/nginx/conf.d/*.conf;
        include /etc/nginx/sites-enabled/*;
    }
    
    
    #mail {
    #   # See sample authentication script at:
    #   # http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript
    #
    #   # auth_http localhost/auth.php;
    #   # pop3_capabilities "TOP" "USER";
    #   # imap_capabilities "IMAP4rev1" "UIDPLUS";
    #
    #
    #   server {
    #       listen     localhost:110;
    #       protocol   pop3;
    #       proxy      on;
    #   }
    #
    #   server {
    #       listen     localhost:143;
    #       protocol   imap;
    #       proxy      on;
    #   }
    #}
              

    2,/etc/hosts文件:

    127.0.0.1    localhost
    127.0.1.1    dp
    
    # The following lines are desirable for IPv6 capable hosts
    ::1     ip6-localhost ip6-loopback
    fe00::0 ip6-localnet
    ff00::0 ip6-mcastprefix
    ff02::1 ip6-allnodes
    ff02::2 ip6-allrouters
    

    3,php文件代码:

    
        <?php
        header("Content-Type:text/html;charset=utf-8");
        $mysqli = mysqli_init();
        $mysqli->set_charset('utf8');
        $conn = $mysqli->real_connect('127.0.0.1','root','123456','test');
    
        if(!$conn){
            echo $mysqli->connect_error;
        }
    
        $obj = $mysqli->query("select * from info");
        $arr = $obj->fetch_all();
        echo '<pre>';
        var_dump($arr);
        echo '</pre>';
        echo '張三';
    
    

    共出现了两个问题:
    1,如题
    2,在php代码中,使用localhost链接数据库就不行,但是使用127.0.0.1就行
    请问这个是什么原因呢?
