VMware 设置

• NAT 模式
• 最小化安装（这会很多软件需要手动安装）
• 静态 IP 地址配置
• 主机名 hostname 配置

静态 IP 地址和主机名 hostname 可以在安装过程中直接通过图形化界面进行配置。

假如 IPv4 地址为 192.168.248.101，那么网关为 192.168.248.2，子网掩码为 255.255.255.0，DNS 服务器为 223.5.5.5 和 223.6.6.6

CentOS-Base.repo 文件

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
