nginx重写索引configuration错误

我们有下面的虚拟服务器设置。 我们希望在访问/doc/ ，nginx会自动访问/doc/index.html ，并使用静态文件/data/doc/site/index.html来提供服务。

 server { listen 8123 default_server; access_log /var/log/nginx/test.access.log; error_log /var/log/nginx/test.error.log; # Make site accessible from http://localhost/ server_name localhost; location /doc { root /data/doc/site; index index.html; rewrite /doc(.*) $1 break; } location / { proxy_pass_header Server; proxy_pass http://127.0.0.1:7001; // !!!not exists!!! } } 

但，

 $ curl http://192.168.1.230:8123/doc/ -v * Trying 192.168.1.230... * Connected to 192.168.1.230 (192.168.1.230) port 8123 (#0) > GET /doc/ HTTP/1.1 > Host: 192.168.1.230:8123 > User-Agent: curl/7.43.0 > Accept: */* > < HTTP/1.1 502 Bad Gateway < Server: nginx/1.4.6 (Ubuntu) < Date: Mon, 21 Dec 2015 07:37:29 GMT < Content-Type: text/html < Content-Length: 181 < Connection: keep-alive < 

和

 $ curl http://192.168.1.230:8123/doc/index.html -v * Trying 192.168.1.230... * Connected to 192.168.1.230 (192.168.1.230) port 8123 (#0) > GET /doc/index.html HTTP/1.1 > Host: 192.168.1.230:8123 > User-Agent: curl/7.43.0 > Accept: */* > < HTTP/1.1 200 OK < Server: nginx/1.4.6 (Ubuntu) < Date: Mon, 21 Dec 2015 07:33:47 GMT < Content-Type: text/html < Content-Length: 11 < Last-Modified: Mon, 21 Dec 2015 06:51:07 GMT < Connection: keep-alive < ETag: "5677a15b-b" < Accept-Ranges: bytes < root index 

重写后，似乎nginx重新匹配一个新位置的变化的URL。 但在文件中，它说

• Nginx重启错误：emerg重复上游
• 在nginx中提供远程文件
• 为什么重写（nginx）redirect301代码？
• Nginx子域名无法正常运行
• nginx gzip_static删除Content-Encoding标头

 last stops processing the current set of ngx_http_rewrite_module directives and starts a search for a new location matching the changed URI; break stops processing the current set of ngx_http_rewrite_module directives as with the break directive; 

它不应search与更改的URI匹配的新位置。

 location /doc/ { alias /data/doc/site/; index index.html; }
