  1. IPADDR地址需要根据创建虚拟机时选择的网卡模式来配置
  2. 如果是桥接模式，就根据你自己路由器的IP网段来设置，一般跟物理机网段相同就行
  3. 如果是NAT模式需要在VMware主界面选择编辑==>虚拟网络编辑器==>NAT模式来查看IP网段
    1. cd /etc/sysconfig/network-scripts/
    2. vi ifcfg-ens33

配置yum源

  1. curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
  2. wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
  1. [root@centos7 ~]# cat   /etc/yum.repos.d/CentOS-Base.repo 
  2. # CentOS-Base.repo
  3. #
  4. # The mirror system uses the connecting IP address of the client and the
  5. # update status of each mirror to pick mirrors that are updated to and
  6. # geographically close to the client.  You should use this for CentOS updates
  7. # unless you are manually picking other mirrors.
  8. #
  9. # If the mirrorlist= does not work for you, as a fall back you can try the 
  10. # remarked out baseurl= line instead.
