1. Hostname

1.1. /etc/hostname

# cat /etc/hostname
web1.example.com
		

1.2. /etc/host.conf

解析順序配置檔案

[root@development bin]# cat /etc/host.conf
order hosts,bind
		

首先在/etc/hosts檔案中尋找,如果不存在,再去DNS伺服器中尋找

1.3. /etc/hosts

IP地址後面TAB符,然後寫主機地址

127.0.0.1       localhost.localdomain localhost
::1             localhost6.localdomain6 localhost6
192.168.1.10	development.example.com development
		

1.4. hosts.allow / hosts.deny

/etc/hosts.allow 和 /etc/hosts.deny

許可IP/禁止IP,相當於黑白名單

1.5. /etc/resolv.conf

		
search example.com
nameserver 208.67.222.222
nameserver 208.67.220.220
