- 修改主机名
只要启动慢就要想到/etc/hosts中用户名没改
（a）
[[email protected] ~]# vi /etc/hosts 127.0.0.1 localhost Dong localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
（b）
[[email protected] ~]# hostname Dong
（c）
[[email protected] ~]# vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=Dong
2. 修改网卡信息
[[email protected] ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 TYPE=Ethernet ONBOOT=yes 开机网卡是否启动 NM_CONTROLLED=yes BOOTPROTO=dhcp USERCTL=no PEERDNS=yes IPV6INIT=no
3. 修改默认语言
[[email protected] ~]# cat /etc/sysconfig/i18n LANG="en_US.UTF-8" SYSFONT="latarcyrheb-sun16"
4.也可以用setup进行修改参数
[[email protected] ~]# setup
