**方便大家学习,天天更新,由于回寝之后才能敲当天的代码,加写说明,可能会慢些,我一步一步全写一下~~**

## **day01**

**今天的目标就是搞下软件仓库,简单的就一笔带过了~~**

#### **1.安装vm和redhat版本安装**

**取名为server,细节不多说~~**

#### **2.软件仓库配置**

```
df //查看挂载目录
```

**每个人都可能不一样哦,这个好像是根据主机名来的,一般没调过都是root,我这里是我的名字~~**

![图片](https://www.zaunekko.com/download/image/web/07.png)

**复制挂载目录**

**之后配置本地yum源**

```
cd /etc/yum.repos.d/
vim myrepos.repo
//编辑为如下即可
[app]
name = app
enable = 1
gpgcheck = 0
//别忘了换自己的路径
baseurl = file:///run/media/zaunekko/RHEL-8-2-0-BaseOS-x86_64/AppStream

[base]
name = base
enable = 1
gpgcheck = 0
baseurl = file:///run/media/zaunekko/RHEL-8-2-0-BaseOS-x86_64/BaseOS

yum makecache //即可成功
```

**如图所示**

#### **3.创建快照**

**别忘了搞个快照~~**

**第一天over~~**

## **day02**

#### **1.再配置两台相同环境的**

**分别取名为client1,client2,细节不说了,克隆不克隆随你,mac别一样就行~~**

#### **2.配置网卡**

**sever,client1,client2,配置相同的虚拟网卡,别选0,1,8,这三个一般别的nat,桥接等等模式会默认配置,想知道的看虚拟网络编辑器那里就知道为什么了,这里不细说,这里我们选了5~~**

![图片](https://www.zaunekko.com/download/image/web/09.png)

#### **3.配置sever虚拟机**

**首先配置network,如下~~**

![图片](https://www.zaunekko.com/download/image/web/10.png)

**之后就可以一直敲了~~**

```

Installed:
  dhcp-server-12:4.3.6-40.el8.x86_64

Complete!
[root@localhost ~]# cat /etc/dhcp/dhcpd.conf 
#
# DHCP Server Configuration file.
#   see /usr/share/doc/dhcp-server/dhcpd.conf.example
#   see dhcpd.conf(5) man page
#
[root@localhost ~]# cp /usr/share/doc/dhcp-server/dhcpd.conf.example /etc/dhcp/dhcpd.conf    //路径写上面查看到的
cp: overwrite '/etc/dhcp/dhcpd.conf'? y
[root@localhost ~]# vim /etc/dhcp/dhcpd.conf

```

**配置如下**

```
# which we don't really recommend.

//在此之前的subnet的代码块都删掉,或者你注释掉,之后配置如下
# A slightly different configuration for an internal subnet.
subnet 1.1.1.0 netmask 255.255.255.0 { //网段和子网号
  range 1.1.1.2 1.1.1.3; //想要分配出的ip
  option domain-name-servers 1.1.1.1; //网关服务器地址,因为我们选择自己找所以网关是自己
  option domain-name "zaunekko.example.org";//随意取
  option routers 1.1.1.1; //同上即可
  default-lease-time 600; //最少租期
  max-lease-time 7200; //最大租期
}
```

**退出来,启动dhcp服务~~**

```
[root@localhost ~]# systemctl restart dhcpd.service
```

**成功~~**

#### **4.配置client01,client02有线连接**

**两个都恢复快照,打开network,重新打开一下有线连接,即可发现ip地址已经被配置,分别为刚刚所想配置的1.1.1.2和1.1.1.3,这里我是client02的ip是1.1.1.3~~**

#### **5.继续回来配置server**

**根据作业所示,需要更改1.1.1.3的固定分配地址为1.1.1.100~~**

**那么就ping一下,就会有arp缓存,就能知道对应的ip对应的mac地址了,应该都记得arp原理吧~~**

```
[root@localhost ~]# arp -a
? (210.30.48.7) at <incomplete> on ens160
? (1.1.1.3) at 00:0c:29:5f:2a:44 [ether] on ens160 //复制此mac地址
? (203.107.6.88) at <incomplete> on ens160
? (1.1.1.2) at 00:0c:29:7c:aa:c9 [ether] on ens160
? (192.168.116.2) at <incomplete> on ens160
```

**接下来更改dhcpd.conf,配置如下**

```
[root@localhost ~]# vim /etc/dhcp/dhcpd.conf

//找到此段,大致为70行
host fantasia {
  hardware ethernet 00:0c:29:5f:2a:44;  //为上步mac地址
  fixed-address 1.1.1.100; //想分配的固定ip
}
```

**退出来,重新启动dhcp服务~~**

```
[root@localhost ~]# systemctl restart dhcpd.service
```

**成功~~**

#### **6.查看client的ip分配是否成功**

**打开对应的client主机,我这里是client1,重新打开一下有线连接,即可发现ip地址已经被配置为1.1.1.100~~**

**如下图所示~~**

![图片](https://www.zaunekko.com/download/image/web/11.png)

**至此,你就可以交作业了,建议再创个快照~~**

## **day02 附加(添加中继)**

**这里我们直接将server和client1调整到第10块虚拟网卡,client2调整到第15块虚拟网卡,并且为clinet1再添加一个网络适配器,调整到第15块虚拟网卡~~**

**准备工作做好之后~~**

#### **1.配置sever**

**首先network配置如下~~**

![图片](https://www.zaunekko.com/download/image/web/12.png)

**因为继刚刚所敲的,然后,只需要敲~~**

```
[root@localhost ~]# route add default gw 1.1.1.2  //因为原来的client1是这个ip,我们想让他做中继

[root@localhost ~]# vim /etc/dhcp/dhcpd.conf  //重新配置一下
subnet 1.1.1.0 netmask 255.255.255.0 { 
  range 1.1.1.2 1.1.1.3;
  option domain-name-servers 1.1.1.2; //更改为client1的
  option domain-name "zaunekko.example.org";
  option routers 1.1.1.2;
  default-lease-time 600;
  max-lease-time 7200;
}
subnet 100.100.100.0 netmask 255.255.255.0 { 
  range 100.100.100.2 100.100.100.3;
  option domain-name-servers 100.100.100.1; //更改为client1另外一个网卡的
  option domain-name "zaunekko.example.org";
  option routers 100.100.100.1;
  default-lease-time 600;
  max-lease-time 7200;
}

[root@localhost ~]# systemctl restart dhcpd.service
```

**成功~~**

#### **2.配置client1**

**重新打开一下有线连接~~**

**配置会变成此~~**

![图片](https://www.zaunekko.com/download/image/web/13.png)

**此时打开第二个网卡并且记住名字,并且配置为如下~~**

![图片](https://www.zaunekko.com/download/image/web/14.png)

**完成之后~~**

![图片](https://www.zaunekko.com/download/image/web/15.png)

**之后可以敲了~~**

```
[root@localhost yum.repos.d]# setenforce 0
[root@localhost yum.repos.d]# systemctl stop firewalld.service
[root@localhost yum.repos.d]# vim /etc/sysctl.conf

//添加如下~~
net.ipv4.ip_forward = 1;

[root@localhost yum.repos.d]# sysctl -p
sysctl: setting key "net.ipv4.ip_forward": Invalid argument
net.ipv4.ip_forward = 1;
[root@localhost yum.repos.d]# cat /proc/sys/net/ipv4/ip_forward

网络工程实验安排

ZaunEkko • 2021 年 06 月 29 日

**方便大家学习,天天更新,由于回寝之后才能敲当天的代码,加写说明,可能会慢些,我一步一步全写一下~~**

## **day01**

**今天的目标就是搞下软件仓库,简单的就一笔带过了~~**

#### **1.安装vm和redhat版本安装**

**取名为server,细节不多说~~**

#### **2.软件仓库配置**

```
df //查看挂载目录
```

**每个人都可能不一样哦,这个好像是根据主机名来的,一般没调过都是root,我这里是我的名字~~**

![图片](https://www.zaunekko.com/download/image/web/07.png)

**复制挂载目录**

**之后配置本地yum源**

[base]
name = base
enable = 1
gpgcheck = 0
baseurl = file:///run/media/zaunekko/RHEL-8-2-0-BaseOS-x86_64/BaseOS

yum makecache //即可成功
```

**如图所示**

![图片](https://www.zaunekko.com/download/image/web/08.png)

#### **3.创建快照**

**别忘了搞个快照~~**

**第一天over~~**

## **day02**

#### **1.再配置两台相同环境的**

**分别取名为client1,client2,细节不说了,克隆不克隆随你,mac别一样就行~~**

#### **2.配置网卡**

![图片](https://www.zaunekko.com/download/image/web/09.png)

#### **3.配置sever虚拟机**

**首先配置network,如下~~**

![图片](https://www.zaunekko.com/download/image/web/10.png)

**之后就可以一直敲了~~**

Transaction Summary
================================================================================
Install  1 Package

Installed:
  dhcp-server-12:4.3.6-40.el8.x86_64

```

**配置如下**

```
# which we don't really recommend.

**退出来,启动dhcp服务~~**

```
[root@localhost ~]# systemctl restart dhcpd.service
```

**成功~~**

#### **4.配置client01,client02有线连接**

**两个都恢复快照,打开network,重新打开一下有线连接,即可发现ip地址已经被配置,分别为刚刚所想配置的1.1.1.2和1.1.1.3,这里我是client02的ip是1.1.1.3~~**

#### **5.继续回来配置server**

**根据作业所示,需要更改1.1.1.3的固定分配地址为1.1.1.100~~**

**那么就ping一下,就会有arp缓存,就能知道对应的ip对应的mac地址了,应该都记得arp原理吧~~**

**接下来更改dhcpd.conf,配置如下**

```
[root@localhost ~]# vim /etc/dhcp/dhcpd.conf

//找到此段,大致为70行
host fantasia {
  hardware ethernet 00:0c:29:5f:2a:44;  //为上步mac地址
  fixed-address 1.1.1.100; //想分配的固定ip
}
```

**退出来,重新启动dhcp服务~~**

```
[root@localhost ~]# systemctl restart dhcpd.service
```

**成功~~**

#### **6.查看client的ip分配是否成功**

**打开对应的client主机,我这里是client1,重新打开一下有线连接,即可发现ip地址已经被配置为1.1.1.100~~**

**如下图所示~~**

![图片](https://www.zaunekko.com/download/image/web/11.png)

**至此,你就可以交作业了,建议再创个快照~~**

## **day02 附加(添加中继)**

**这里我们直接将server和client1调整到第10块虚拟网卡,client2调整到第15块虚拟网卡,并且为clinet1再添加一个网络适配器,调整到第15块虚拟网卡~~**

**准备工作做好之后~~**

#### **1.配置sever**

**首先network配置如下~~**

![图片](https://www.zaunekko.com/download/image/web/12.png)

**因为继刚刚所敲的,然后,只需要敲~~**

```
[root@localhost ~]# route add default gw 1.1.1.2  //因为原来的client1是这个ip,我们想让他做中继

[root@localhost ~]# systemctl restart dhcpd.service
```

**成功~~**

#### **2.配置client1**

**重新打开一下有线连接~~**

**配置会变成此~~**

![图片](https://www.zaunekko.com/download/image/web/13.png)

**此时打开第二个网卡并且记住名字,并且配置为如下~~**

![图片](https://www.zaunekko.com/download/image/web/14.png)

**完成之后~~**

![图片](https://www.zaunekko.com/download/image/web/15.png)

**之后可以敲了~~**

```
[root@localhost yum.repos.d]# setenforce 0
[root@localhost yum.repos.d]# systemctl stop firewalld.service
[root@localhost yum.repos.d]# vim /etc/sysctl.conf

//添加如下~~
net.ipv4.ip_forward = 1;

[root@localhost yum.repos.d]# systemctl --system daemon-reload 
[root@localhost yum.repos.d]# systemctl restart dhcrelay.service 
[root@localhost yum.repos.d]#

```

**成功~~**

#### **3.查看client2**

**重新打开一下client2的有线连接~~**

**如下~~**

![图片](https://www.zaunekko.com/download/image/web/16.png)

**发现成功~~**

## day03

#### 1.配置sever
