1.1 编辑虚拟机设置
点击"添加"，选择"网络适配器"，然后选择"桥接模式"，最后点击"完成"。
配置内网和外网IP地址
02
2.1 配置hosts文件
2.2 配置网关
2.3 配置DNS服务器
在Linux虚拟机加上windows的网关。
2.4 配置本机网段IP
2.4.1 打开网络配置(图形界面)
本虚拟机的VMnet8(NET模式)的网段是192.168.117.1 。
2.4.2 重启网络，检查配置的IP
重启网络服务。
查看IP地址是否修改成功，显示为192.168.117.100，成功！
2.5 配置连接外网的IP
2.5.1 打开网络配置(图形界面)
记得开启network，"Automatically connect to ..."
Linux的网关和DNS都是WIN10系统的网关地址。Device就是添加网卡时的MAC地址，这里选择默认即可。
2.5.2 重启网络，检查配置的IP
2.6 检查是否能够上外网
2.6.1 ping
2.6.2 浏览器检查
03
3.1 安装VMware Tools
如果没有安装，请选择安装。一般情况会在安装RedHat时在正下方提示。安装之后，可以在虚拟机和WIN10之间进行复制粘贴。
3.2 点击快照，方便回滚
快照的意思就是某个时刻的镜像，可以选择该时刻进行快照，做好之后，随时可以回滚。我一般过一段时间就会把这些较基础的快照删掉，避免占用空间。
3.3 配置yum源
RHEL的YUM源需要注册用户才能更新使用，由于CentOS和RHEL基本没有区别，并且CentOS已经被REHL收购。所以将RHEL的YUM源替换为CentOS即可。
3.3.1 查看当前的yum源
[root@RHEL-INIT ~]# yum repolist
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
repolist: 03.3.2 卸载当前YUM源
rpm -qa | grep yum | xargs rpm -e --nodeps
rpm -qa |grep python-urlgrabber|xargs rpm -e --nodeps3.3.3 下载相关的RPM包
将红帽的YUM源改为Centos的yum源
[root@RHEL-INIT ~]# mkdir /storage
[root@RHEL-INIT ~]# mkdir -p /storage/rpm
[root@RHEL-INIT ~]# cd /storage/rpm/
[root@RHEL-INIT rpm]# pwd
/storage/rpm
[root@RHEL-INIT rpm] wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-163.el7.centos.noarch.rpm

[root@RHEL-INIT rpm] wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-urlgrabber-3.10-9.el7.noarch.rpm3.3.4 安装RPM包
注意以下亮点喔，跟同学们说过很多次的了。
用root安装
yum-plugin-fastestmirror和yum-3.4.3要一起安装。
rpm -ivh python-iniparse-0.4-9.el7.noarch.rpm
rpm -ivh python-urlgrabber-3.10-9.el7.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.4-10.el7.x86_64.rpm 3.3.5 使用163的Centos源更换yum源
[root@RHEL-INIT rpm] cd /etc/yum.repos.d/
[root@RHEL-INIT yum.repos.d]# wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
[root@RHEL-INIT yum.repos.d]# cp CentOS7-Base-163.repo CentOS7-Base-163.repo.bak
[root@RHEL-INIT rpm] vi CentOS7-Base-163.repo
1. 执行":"，然后输入:"%s/../CentOS-7"
2. 执行":"，然后输入:"%s/?release=$releasever/?release=$releasever=7.6"
3. 执行":"，然后输入:"%s/centos\/$releasever/centos\/7" 如果不会使用命令，那么老铁恰好用的也是红帽7，那就请复制下面的"奥利给"内容吧。
[root@RHEL-INIT yum.repos.d]# cat CentOS7-Base-163.repo
# 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.
