一,配置IP地址
临时改变IP地址,重启后失效。切换到root用户,
1. ifconfig ce0 down
2. ifconfig ce0 192.168.0.100 netmask 255.255.255.0 up
如果想永久改变IP地址,涉及到以下三个文件。
1. /etc/hostname.ce0
此文件中需加入主机名,本例中加入:
dbserver
2. /etc/hosts 此文件为一个动态链接,链接至/etc/inet/hosts
此文件中需要添加如下一行:
IP地址 主机名 loghost
192.168.0.100 dbserver loghost
3. /etc/nodename
此文件中需加入主机名,本例中加入:
dbserver
重启网络服务或者机器重启后IP地址即会改变。
二、改变主机名
当系统要求改变一台机器的主机名是,需要修改以下文件:
/etc/inet/hosts 存在动态链接,/etc/hosts链接至此文件
/etc/nodename
/etc/hostname.interface
三、配置DNS服务器
设置DNS客户端需要两个步骤:
1.创建/etc/resolv.conf文件,并添加DNS服务器IP和名称
# more /etc/resolv.conf
nameserver 192.0.0.88
nameserver 192.0.0.188
2.修改/etc/nsswitch.conf配置,在hosts后加上dns 解析
# vi /etc/nsswitch.conf
