RHEL7虚拟机实验快照
配置虚拟机连接网络
首先确保NetworkManager服务正常运行
[root@administrator ~]# systemctl status NetworkManager

PING百度
[root@administrator ~]# ping baidu.com
ping: unknown host baidu.com
PING百度无法PING通，下面开始配置
两种配置方式：修改配置文件/使用图形界面工具
- 修改网卡配置文件
打开配置文件
[root@administrator ~]# vim /etc/sysconfig/network-scripts/ifcfg-eno16777736
修改前的原配置文件
TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no

UUID=ea5c55cd-2fcf-4ed8-a31d-90e86fe56925
DEVICE=eno16777736
ONBOOT=no
修改后的配置文件
TYPE=Ethernet
#static/none/dhcp 桥接模式设置为dhcp即可
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yesgi
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=eno16777736
UUID=ea5c55cd-2fcf-4ed8-a31d-90e86fe56925
DEVICE=eno16777736
#启用
ONBOOT=yes
重启网络服务
[root@administrator ~]# systemctl restart network
再次PING百度，虚拟机已经能正常上网
[root@administrator ~]# ping baiu.com

从上面看出宿主机的网段在0网段:192.168.0.1（默认网关）
设置在这个网段内即可（确保你设置的ip没有在局域网内已经被使用）
再次修改配置文件为如下配置：
TYPE=Ethernet
BOOTPROTO=none
IPADDR=192.168.0.254
PREFIX=32
GATEWAY=192.168.0.1
DNS1=114.114.114.114

IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=eno16777736
UUID=ea5c55cd-2fcf-4ed8-a31d-90e86fe56925
DEVICE=eno16777736
ONBOOT=yes
配置说明
BOOTPROTO：IP地址类型 值为none/static/dhcp，配置为静态ip设置为none或者static
IPADDR：IP地址
ONBOOT：是否启动
PREFIX：掩码长度
DNS1：DNS SERVER
GATEWAY：默认网关
修改完毕后重启网络服务并PING百度已能正常上网
[root@administrator ~]# systemctl restart network

- 使用图形界面工具NetworkManager TUI
[root@administrator ~]# nmtui
然后根据图形界面傻瓜式操作即可
关闭防火墙并设置开机自动关闭
查看防火墙状态
[root@administrator ~]# systemctl status firewalld.service

关闭防火墙
[root@administrator ~]# systemctl stop firewalld
设置开机自动关闭
[root@administrator ~]# systemctl disable firewall
再次查看防火墙状态发现已经成功关闭
[root@administrator ~]# systemctl status firewalld.service

关闭selinux并设置开机自动关闭
临时关闭：本次操作后关闭，下次重启依然会开启
[root@administrator ~]# setenforce 0
永久关闭
[root@administrator ~]# vim /etc/sysconfig/selinux
原配置文件
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=enforcing
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
修改为

配置本地yum源
配置本地yum源之前先挂载系统盘
切换到/etc/yum.repos.d/目录下，删除该目录下的所有文件(请勿在真机操作：先备份)
[root@administrator yum.repos.d]# cd /etc/yum.repos.d/
[root@administrator yum.repos.d]# rm -rf *
[root@administrator yum.repos.d]# ll
total 0
创建yum源配置文件
[root@administrator yum.repos.d]# vim redhat.repo
添加以下内容 保存退出
[local-repository]
name=local-repository
baseurl=file:///mnt
enabled=1
gpgcheck=0
查看以下刚才编辑的内容
administrator yum.repos.d]# cat local.repo
