news 2025/8/24 16:29:33

综合实验(所有设备关闭防火墙和selinux)

在appsrv上部署主dns，为example.com提供域名解析

安装bind bind-chroot

root@appsrv ~]# yum install bind bind-chroot -y

编辑主配置文件，全局配置文件，正向解析文件

[root@appsrv ~]# vim /etc/named.conf 
options {listen-on port 53 { any; };listen-on-v6 port 53 { any; };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; };

[root@appsrv ~]# cd /var/named/
[root@appsrv named]# cp -p named.localhost xie.com
[root@appsrv named]# cp -p named.empty com.xi

[root@appsrv ~]# vim /etc/named.rfc1912.zones
zone "example.com" IN {type master;file "xie.com";allow-update { none; };
};zone "100.168.192.in-addr.arpa" IN {type master;file "com.xie";allow-update { none; };
};

[root@appsrv ~]# vim /var/named/xie.com
$TTL 1D
@       IN SOA  appsrv.example.com. root.example.com. (2025082301      ; serial1D      ; refresh1H      ; retry1W      ; expire3H )    ; minimumNS      appsrv.example.com.
appsrv IN  A 192.168.100.10
www  IN  A 192.168.100.10

[root@appsrv ~]# systemctl restart named
[root@appsrv ~]# systemctl enable named

2.配置DHCP服务器，为client客户端网络分配地址，地址池范围：192.168.0.110-192.168.0.190/24

安装 dhcp

[root@storagesrv ~]# yum install dhcp -y

覆盖dhcp主配置文件

[root@storagesrv ~]# cp -p /usr/share/doc/dhcp*/dhcpd.conf.example /etc/dhcp/dhcpd.conf
cp: overwrite ‘/etc/dhcp/dhcpd.conf’? y

编辑dhcp主配置文件

[root@storagesrv ~]# vim /etc/dhcp/dhcpd.confsubnet 192.168.100.0 netmask 255.255.255.0 {
}subnet 192.168.0.0 netmask 255.255.255.0 {range 192.168.0.110 192.168.0.190;option routers 192.168.0.254;default-lease-time 600;max-lease-time 7200;
}

STORAGESRV:

一、NFS服务

1、共享/webdata目录

2、用于存储appsrv主机的web数据

3、仅允许appsrv主机访问该共享

安装 nfs-utils rpcbind

[root@storagesrv ~]# yum install nfs-utils rpcbind -y

创建共享目录

[root@storagesrv ~]# mkdir /webdata
[root@storagesrv ~]# vim /etc/exports/webdata 192.168.100.10/24(rw)
[root@storagesrv ~]# chmod o+w /webdata

[root@storagesrv ~]# systemctl restart rpcbind
[root@storagesrv ~]# systemctl enable rpcbind
[root@storagesrv ~]# systemctl restart nfs
[root@storagesrv ~]# systemctl enable nfs

nfs客户端（在主dns上完成）

创建挂载点/luoqi

[root@appsrv ~]# mkdir /luoqi

永久挂载共享目录/webdata

[root@appsrv ~]# vim /etc/fstab
192.168.100.20:/webdata /luoqi nfs defaults 0 0

WEB服务

1、DocumentRoot为/luoqi

2、要求通过http://www.example.com能够成功访问该站点，内容为welcome to luoqi.

安装httpd

[root@appsrv ~]# yum install httpd -y

复制虚拟主机的配置文件到/etc/httpd/conf.d/

[root@appsrv ~]# cp -p /usr/share/doc/httpd-2.4.6/httpd-vhosts.conf /etc/httpd/conf.d/

编辑虚拟主机配置文件

[root@appsrv ~]# vim /etc/httpd/conf.d/httpd-vhosts.conf<VirtualHost 192.168.100.10:80>    DocumentRoot "/luoqi"ServerName www.example.com<Directory "/luoqi">AllowOverride NoneRequire all granted
</Directory>
</VirtualHost>[root@appsrv ~]# systemctl restart httpd
[root@appsrv ~]# systemctl enable httpd

[root@appsrv ~]# cd /luoqi
[root@appsrv luoqi]# ls
[root@appsrv luoqi]# echo welcome to luoqi > index.html

配置dhcp中继，开启ip转发功能使client能够自动获取ip

dhcp中继

NAT模式网卡ip地址：192.168.100.254

仅主机模式网卡ip为：192.168.0.254

client

主机名：client.example.com

网卡为仅主机模式，自动获取ip地址，获取的ip地址的网段为192.168.0.0/24

dhcp中继nat网卡配置

[root@routersrv ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens33IPADDR=192.168.100.254

仅主机网卡配置

[root@routersrv ~]# nmcli connection 
NAME                UUID                                  TYPE      DEVICE 
ens33               c96bc909-188e-ec64-3a96-6a90982b08ad  ethernet  ens33  
virbr0              906c8b56-9adf-4276-aaf4-dc767b596e7b  bridge    virbr0 
Wired connection 1  f7f4387c-ce62-3ed3-b7dc-674fb781fcd9  ethernet  ens36

[root@routersrv ~]# nmcli connection delete Wired\ connection\ 1
[root@xieyuhui3 ~]# nmcli connection add con-name ens36 ifname ens36 type ethernet 
[root@xieyuhui3 ~]# nmcli connection modify ens36 ipv4.addresses 192.168.0.254/24 ipv4.gateway 192.168.0.254 ipv4.method manual connection.autoconnect yes
[root@routersrv ~]# nmcli connection up ens36

[root@routersrv ~]# systemctl restart network

client网卡配置

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
DEVICE=ens33
ONBOOT=yes

dhcp中继安装dhcp，开启IP转发

[root@routersrv yum.repos.d]# yum install dhcp -y
[root@routersrv ~]# vim /etc/sysctl.confnet.ipv4.ip_forward = 1[root@routersrv ~]# sysctl -pnet.ipv4.ip_forward = 1[root@routersrv ~]# dhcrelay 192.168.100.10

1、在storagesrv使用nslookup命令解析www.example.com，并截图
