windows上安装安装Vmware,安装centos7

在公司的电脑使用的是windows系统,有时候需要测试一些东西,可以使用自己购买的服务器,如果需要几台来测试那就需要安装虚拟机来安装操作系统

安装Vmware

安装和激活Vmvare

下载centos7

下载地址:http://isoredirect.centos.org/centos/7/isos/x86_64/

使用国内下载点:https://mirrors.aliyun.com/centos/7/isos/x86_64/下载CentOS-7-x86_64-DVD-2009.iso

下载安装这里就不详细介绍

网络配置

找到自己电脑的ip地址,按网段分配一个没有使用的IP给centos的系统ip

进入网络配置目录

[rh@localhost ~]$ cd /etc/sysconfig/network-scripts/
[rh@localhost network-scripts]$ ls
ifcfg-ens33  ifdown-eth   ifdown-post    ifdown-Team      ifup-aliases  ifup-ipv6   ifup-post    ifup-Team      init.ipv6-global
ifcfg-lo     ifdown-ippp  ifdown-ppp     ifdown-TeamPort  ifup-bnep     ifup-isdn   ifup-ppp     ifup-TeamPort  network-functions
ifdown       ifdown-ipv6  ifdown-routes  ifdown-tunnel    ifup-eth      ifup-plip   ifup-routes  ifup-tunnel    network-functions-ipv6
ifdown-bnep  ifdown-isdn  ifdown-sit     ifup             ifup-ippp     ifup-plusb  ifup-sit     ifup-wireless

更改配置

[rh@localhost network-scripts]$ sudo vi ifcfg-ens33 
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static  #dhcp更改
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=0c8758ef-1d63-4957-ab77-b8c05e4f278d
DEVICE=ens33
ONBOOT=yes  #开机启动no改为yes,增加以下配置
IPADDR=192.168.2.138
GATEWAY=192.168.2.1
NETMASK=255.255.255.0
DNS1=8.8.8.8
DNS2=8.8.4.4

重启网络

[rh@localhost network-scripts]$ sudo systemctl restart network

测试网络

[rh@localhost network-scripts]$ ping www.baidu.com

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

下载新的 CentOS-Base.repo 到 /etc/yum.repos.d/

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

运行 yum makecache 生成缓存
