nginx: [emerg] could not build server_names_hash

报错信息

nginx: [emerg] could not build server_names_hash, you should increase server_names_hash_bucket_size: 32
nginx: configuration file /etc/nginx/nginx.conf test failed

解决办法

在Nginx的http字段内添加如下代码，放大默认bucket_size

http {
server_names_hash_bucket_size 64;
…
}

加入server_names_hash_bucket_size 64;这行问题，解决了。

暂时没有深入研究原因。
