nginx中的多个服务器块仅指向1个块

Question

我曾尝试在我的服务器上设置nginx，但我无法创建多个服务器块。

我在sites-available文件夹中创建了两个文件：xxx.com和yyy.com，并在启用站点的文件夹中对其进行符号链接。但这两个领域只指向一个网站。喜欢打开xxx.com打开yyy.com

对于网站xxx.com和yyy.com（用yyy.com替换xxx.com），我在网站中有以下配置文件：

server {
    listen 80;

    server_name xxx.com www.xxx.com;
    root /var/www/xxx.com/public_html;
    index index.html index.php index.htm index.nginx-debian.html;

    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            try_files $uri $uri/ /index.php?$args =404;
    }
    location ~ \.php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/run/php/php7.0-fpm.sock;
            fastcgi_read_timeout 300;
    }
}

默认：

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    # SSL configuration
    #
    #listen 443 ssl http2 default_server;
    #listen [::]:443 ssl http2 default_server;
    #
    # Note: You should disable gzip for SSL traffic.
    # See: https://bugs.debian.org/773332
    #
    # Read up on ssl_ciphers to ensure a secure configuration.
    # See: https://bugs.debian.org/765782
    #
    # Self signed certs generated by the ssl-cert package
    # Don't use them in a production server!
    #
    #include snippets/self-signed.conf;
    #include snippets/ssl-params.conf;


    #root /var/www/public_html;

    # Add index.php to the list if you are using PHP
    index index.html index.php index.htm index.nginx-debian.html;

    server_name _;
    #location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
    #       try_files $uri $uri/ /index.php?$args;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #       include snippets/fastcgi-php.conf;
    #
    #       # With php7.0-cgi alone:
    #       fastcgi_pass 127.0.0.1:9000;
    #       # With php7.0-fpm:
    #       fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    #        fastcgi_read_timeout 300;
    }
}

我还在/ etc / hosts中为thre各个域添加了条目，并设置了nginx.conf server_names_hash_bucket_size 64;。

我能错过什么？
