nginx 1.9 无法启动 80 以外的其他端口

我安装了 phpmyadmin，删除了 apache2，然后在 /etc/nginx/sites-available/phpmyadmin 中进行了如下配置

# Generally, you will want to move this file somewhere, and start with a clean

# Default server configuration

server {
        listen 8081;
        listen [::]:8081;

        # SSL configuration
        #
        # listen 443 ssl default_server;
        # listen [::]:443 ssl default_server;
        #
        # Note: You should disable gzip for SSL traffic.

        #
        # include snippets/snakeoil.conf;

        root /usr/share/phpmyadmin;

        # Add index.php to the list if you are using PHP
        index index.php index.html 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/ =404;
        }

        # 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;
        }

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

我只能看到 80 端口打开

$ sudo netstat -tlnp | grep nginx
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      25160/nginx -g daem
tcp6       0      0 :::80                   :::*                    LISTEN      25160/nginx -g daem

nginx 状态似乎显示错误

php7.0-fpm 似乎没问题

我的配置有错误吗？

答案1

将 /etc/nginx/sites-available/phpmyadmin 符号链接到 /etc/nginx/sites-enabled/phpmyadmin 并重新启动 nginx

# ln -s /etc/nginx/sites-available/phpmyadmin /etc/nginx/sites-enabled/

这是因为应该这样做以便将新的服务器块文件添加到 nginx 工作中。
