环境搭建

创建centos7虚拟机

这里一定内存不能少于8G，不然后面安装容易出问题！！还有虚拟化一定要勾上！！！

启动虚拟机centos7

选中文，你要英文好选英语也行。

选配置分区，可以不配，可以不配！！！不影响！！！我同学没分区照样能做！！！

可以不分区，选默认也一样，主要我电脑存储空间本来就不够，分区分了个寂寞！！

ens33要打开，后面下载openstack要网的！！

划重点：最小安装，分区可以不分选默认，禁用Kdump，ens33必须打开！！

设置root密码，待会ssh要用。

ssh连接

安装完成后，登录，查ip地址

使用SecureCRT 连接

ssh成功连上

测下网络，能访问互联网。

安装前的设置

禁用防火墙

[root@localhost ~]#  systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.

[root@localhost ~]#  vi /etc/selinux/config
# This file controls the state of SELinux on the system.

重启

[root@localhost ~]# reboot

禁用 NetworkManager服务

Last login: Tue Apr 23 07:36:39 2024 from 192.168.196.1
[root@localhost ~]# systemctl disable NetworkManager
Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.
[root@localhost ~]# systemctl stop NetworkManager

启用 network 服务

[root@localhost ~]# systemctl enable network
network.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig network on
[root@localhost ~]# systemctl start network

修改主机名以及映射

[root@localhost ~]# hostnamectl set-hostname node-a
[root@localhost ~]# vi /etc/hosts

        cirros001 => 百度www.baidu.com【√】
        cirros001 => centos7 192.168.196.44【√】

        cirros001 => 物理机win10 192.168.196.1【×】
        物理机win10 => cirros001 192.168.196.20【×】
        
        等多一会，再次尝试ping，可以用Wireshare抓包观察。
        
        cirros001能ping网关196.2物理机196.1，也能访问互联网，如下：
        
        win10也能ping通cirros001绑定的浮动ip192.168.196.20
        
        注：如果win10能ping云主机cirros001，云主机cirros001却无法ping通物理机win10，把物理机win10的防火墙关掉！！
        
        抓包验证
        
        云主机cirros001的ip地址为10.10.10.44，抓包时真正通信的是其绑定的浮动ip192.168.196.20
