网卡静态地址配置

## Configure eth0
#
# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"
NM_CONTROLLED="yes"
ONBOOT=yes
HWADDR=A4:BA:DB:37:F1:04
TYPE=Ethernet
BOOTPROTO=static
NAME="System eth0"
UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03
IPADDR=192.168.1.44
NETMASK=255.255.255.0


## Configure Default Gateway
#

HOSTNAME=centos6
GATEWAY=192.168.1.1


## Restart Network Interface
#

/etc/init.d/network restart

## Configure DNS Server
#
# vi /etc/resolv.conf

nameserver 8.8.8.8      # Replace with your nameserver ip
nameserver 192.168.1.1  # Replace with your nameserver ip

磁盘格式化

yum install -y xfsprogs-devel

时区调整

cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
修改为中国的东八区# vi /etc/sysconfig/clockZONE="Asia/Shanghai"
UTC=false

配置主机名

假设机器名为XX

1. 使用hostname XX给系统配置机器名
2. 查看/etc/sysconfig/network， 确保HOSTNAME与上面配置的一致
3. 确保 /etc/hosts文件里面有如下三行，至少有最后一行。
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.0.111 XX
