Nginx: could not build the server_names_hash 解决办法

# /etc/init.d/nginx reload
 * Reloading nginx configuration nginx                                            [fail]

# nginx -t
nginx: [emerg] could not build the server_names_hash, you should increase either server_names_hash_max_size: 512 or server_names_hash_bucket_size: 64
nginx: configuration file /etc/nginx/nginx.conf test failed

# tail /var/log/nginx/error.log
2015/01/28 10:21:51 [emerg] 22362#0: could not build the server_names_hash, you should increase either server_names_hash_max_size: 512 or server_names_hash_bucket_size: 64

解决办法是在 nginx 配置文件的 http 段中增加如下配置：

# vi /etc/nginx/nginx.conf
...
http {
        ...
        server_names_hash_max_size 512;
        server_names_hash_bucket_size 128;
        ...
}
...
