Experimental requirements:

1.sw2 is a layer 2 switch, with three vlan,f1/1-3s of vlan10,vlan20,vlan100 as access links and f1amp 0 as trunk links.

2.sw1 is a layer 3 switch, which provides gateways for three vlan, vlan10:192.168.10.1/24, vlan20:192.168.20.1/24, vlan100:192.168.100.1/24, and the external network interface is f1Uniplex 12.0.0.1Unix 24.

3. Local area network internal Linux server set up dhcp service function to provide addresses for vlan10,vlan20 and vlan100, address range:

Vlan10:192.168.10.100~192.168.10.200 subnet mask: 255.255.255.0 gateway 192.168.10.1Univer 24

Vlan20:192.168.20.100~192.168.20.200 subnet mask: 255.255.255.0 gateway 192.168.20.1 Universe 24

Vlan100:192.168.100.100~192.168.100.200 subnet mask: 255.255.255.0 gateway 192.168.100.1 Universe 24

The address of the dns server is: 192.168.100.100Universe 24

Among them, the win10-1 host always gets the 192.168.10.18 win10 24 address, and the dhcp-2 server automatically assigns the address.

4. The local area network internal Linux server sets up the DNS service function to resolve the www.kgc.com and www.yun.com domain names, the resolution address is 14.0.0.14 Web server, while the DNS server provides pan-domain name resolution function, and the resolution address is 8.8.8.8

5. In the external network, there is a WEB server built by server2016, and the virtual machine host is established to provide two websites, namely www.kgc.com and www.yun.com, to customize the differential display of the home page, to achieve the final interconnection of the whole network, and the functional access is sound.

Experimental operation: 1. GNS3 setting

1. Build the topology diagram in GNS3.

two。 First of all, configure the sw2.

2. Preparation of virtual machine experiment

1. In the Linux system, install the related programs of DHCP and DNS services.

Input: yum install dhcp-y input: yum install bind-y

two。 Bind the win10-1 system as a VMnet1 network card.

3. Bind the win10-2 system as a VMnet2 network card.

4. Bind the sever2016 system to the VMnet3 network card.

5. Bind the Linux system to the VMnet8 network card.

6. Change the type of the VMnet8 Nic to host-only mode and turn off the ability to assign IP addresses with the local DHCP server.

3. Configure DHCP service

1. First make a copy of the dhcp service profile template to overwrite the original profile. At the same time, edit it with the vim editor.

Input: cp/ usr/share/doc/dhcp-4.2.5/dhcpd.conf.exmple / etc/dhcp/dhcpd.conf input: yes input: vim / etc/dhcp/dhcpd.conf

two。 Change the dhcp server address configuration file "option domain-name-servers ns1.example.org, ns2.example.org;" in the configuration file to "option domain-name-servers 192.168.100.100;"

3. Add the address assignment file for three network segments: subnet is the network segment, netmask is the subnet mask, range is the allocation range of ip addresses, and option routers is the gateway. (pay attention to the format. Any error in the configuration file will cause the service to fail to start.)

Subnet 192.168.10.0 netmask 255.255.255.0 {range 192.168.10.100 192.168.10.200; option routers 192.168.10.1;} subnet 192.168.20.0 netmask 255.255.255.0 {range 192.168.20.100 192.168.20.200; option routers 192.168.20.1 } subnet 192.168.100.0 netmask 255.255.255.0 {range 192.168.100.100 192.168.100.200; option routers 192.168.100.1;}

4. Query the MAC address of the win10-1 system.

Input: ipconfig / all

5. Add a fixed ip assigned configuration ask price in the dhcp configuration file "/ etc/dhcp/dhcpd.conf".

Host fantasia {hardware ethernet 00VOCVRO 29VOUR 1EVOLAR 27LARO 9B; fixed-address 192.168.10.18;}

6. Use the vim editor to configure the network card and set a fixed IP address.

Enter: vim / etc/sysconfig/network-scripts/ifcfg-ens33 change dhcp to static add: IPADDR=192.168.100.100NETMASK=255.255.255.0GATEWAY=192.168.100.1

7. Restart the network service to see if the ip address is set successfully.

Input: systemctl restart network input: ifconfig

8. Start the dhcp service with the "systemctl start dhcpd" command.

9. Use the "ipconfig" command to view the IP address of the win10-1 system, and successfully obtain the fixed assigned ip address.

10. Use the "ipconfig" command to check the IP address of the win10-2 system, and successfully get the ip address of the address pool.

Configure the DNS server

1. Use the vim editor to edit the main configuration file of the dns service.

Enter: vim / etc/named.confoptions {listen-on port 53 {any;}; listen-on-v6 port 53 {:: 1;}; directory "/ var/named"; dump-file "/ var/named/data/cache_dump.db"; statistics-file "/ var/named/data/named_stats.txt"; memstatistics-file "/ var/named/data/named_mem_stats.txt" Recursing-file "/ var/named/data/named.recursing"; secroots-file "/ var/named/data/named.secroots"; allow-query {any;}

two。 Use the vim editor to edit the zone profile for the dns service.

Enter: vim / etc/named.rfc1912.zoneszone "kgc.com" IN {type master; file "kgc.com.zone"; allow-update {none;};}; zone "yun.com" IN {type master; file "yun.com.zone"; allow-update {none;};}

3. Enter the "/ var/named" directory, first make a copy of "named.localhost" named "kgc.com.zone" with the "cp-p" command, and then edit it with the vim editor.

Input: cd / var/named input: cp-p named.localhost kgc.com.zone input: vim kgc.com.zone$TTL 1D @ IN SOA @ rname.invalid. (0; serial 1D; refresh 1H; retry 1W; expire 3H) Minimum NS @ A 127.0.0.1www IN A 14.0.0.14 * IN A 8.8.8.8

4 then use the "cp-p" command to copy a "kgc.com.zone" file named "yun.com.zone", then turn off the firewall and enhanced security features, and turn on the dns service.

Input: cp-p kgc.com.zone yun.com.zone input: systemctl stop firewalld.servce input: setenforce 0 input: systemctl start named

5. On the win10-1 system, use the "nslookup" command to check whether the dns server can parse, and the result is successful.

6. On the win10-2 system, use the "nslookup" command to check whether the dns server can resolve, and the result is also successful.

5. Configure Web service

1. Add web service functionality to the server2016 system. (omit simple steps)

two。 Set a fixed ip address to the server2016 system and turn off the firewall function.

3. Add two web sites, "kgc" and "yun".

4. At the command prompt, create your own Web site files under the physical path directory of the two sites.

C:\ Users\ Administrator > cd. /.. C:\ > cd kgc.siteC:\ kgc.site > echo "this is KGCC packages!" > index.htmlC:\ kgc.site > cd.. C:\ > cd yun.siteC:\ yun.site > echo "this is yunks!" > index.htmlC:\ yun.site >

5. Using win10-2 system to visit two websites respectively, both of them can be visited successfully.
