nginx -t报警告如下:

[emerg]: could not build the proxy_headers_hash, you should increase either proxy_headers_hash_max_size: 512 or proxy_headers_hash_bucket_size: 64


修改nginx.conf,在http段中加如下面2行:

http{
   ......
   proxy_headers_hash_max_size 51200;
   proxy_headers_hash_bucket_size 6400;
   ....
}


nginx -t 可以发现问题已经解决了。

重启nginx(service nginx restart)即可。
