看题主配置里面有laravel,看来是跟php有关,如果是php,那么题主你应该先去下载php5-fpm才对,因为nginx本身不像apache一样会执行php程序,而是交给php5-fpm执行.

所以,题主你的步骤应该如下 :

• 下载php5-fpm

• 配置nginx,使nginx跟fpm通信,网上有很多配置方法,我不重复,这里指提醒一点 : nginx跟fpm通信方式有两种,一个是通过ip,一个是通过socket.fpm跟nginx里面要配置成同一种通信方式!!

• 最后测试是否成功.当然有可能到了这里还会出现访问页面下载下来的情况,如果遇到这个情况就需要再排查了,但是题主先搞定fpm比较稳妥.

为了更好的解决题主的问题,我扑出一份我刚刚在ubuntu14.04环境下的配置

server {
        listen 80 default_server;
        listen [::]:80 default_server ipv6only=on;

        root /var/www/html;
        index index.php index.html index.htm;

        # Make site accessible from http://localhost/
        server_name localhost;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
                # Uncomment to enable naxsi on this location
                # include /etc/nginx/naxsi.rules
        }

        # Only for nginx-naxsi used with nginx-naxsi-ui : process denied requests
        #location /RequestDenied {
        #       proxy_pass http://127.0.0.1:8080;    
        #}

        #error_page 404 /404.html;

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

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        location ~ \.php$ {
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
        ## NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini

                # With php5-cgi alone:
        #       fastcgi_pass 127.0.0.1:9000;
        #       # With php5-fpm:
                fastcgi_pass unix:/var/run/php5-fpm.sock;
                fastcgi_index index.php;
                include fastcgi_params;
        }

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

改动的地方不多 :

• index我把index.php放在第一位置

• root路径,这里注意最后路径不要有 /

• 去掉跟php有关的注释,我在fpm的 /etc/php5/fpm/pool.d/www.conf中找到listen = /var/run/php5-fpm.sock,说明fpm是开启了socket,所以nginx的fastcgi_pass参数也是socket.

譬如php结尾，你要用php的cgi去解析

#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;
#}
这串代码我取消注释 nginx restart 会报错
