[emerg] could not build the server_names_hash...
开始使用nginx只有一个虚拟主机，默认server_name 会使用 localhost, 今天配置nginx的server_name是一个正式存在的域名的时候，报错如下：
root@pts/0 $ nginx -t
nginx: [emerg] could not build the server_names_hash, you should increase server_names_hash_bucket_size: 32
nginx: configuration file /etc/nginx/nginx.conf test failed
How to fix
在nginx的配置文件nginx.conf的http段添加如下配置：
# vi /etc/nginx/nginx.conf
...
http {
...
server_names_hash_max_size 512;
server_names_hash_bucket_size 128;
...
}
... root@pts/0 $ nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
nginx官方对server_name的说明请参考 链接
实例配置：
cat /etc/nginx/nginx.conf
client_max_body_size 100M;
client_body_buffer_size 128k;
proxy_buffers 8 512k;
proxy_buffer_size 512k;
proxy_busy_buffers_size 512k;
proxy_temp_file_write_size 512k;
