nginx报错500-地址命名不能为数字的坑

新加接口时，新建Nginx一直报500

后查询原因，是set $xxxUrl的时候命名为111url的数字，把数字改成字母就可以了

listen       80;
    server_name  lo.xxx.xxxx.com;

    #charset koi8-r;

    #access_log  logs/host.access.log  main;

    set $passUrl http://192.xxxx;

    location / {
        root   C:\Users\zhuangcui\AppData\Local\.fis-xxxx-tmp\www;
        index  index.html;
        autoindex on;
        autoindex_exact_size off;
        autoindex_localtime on;
    }

    location ~ ^/exxx {
        proxy_redirect     off;
        proxy_set_header   Host             $host;
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_pass         $passUrl;
   }
   location ~ ^/exxxx {
        proxy_redirect     off;
        proxy_set_header   Host             $host;
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_pass         $passUrl;
   }
