[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：

[email protected]/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;
        ...
}
...

[email protected]/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;
