任务需求：客户端通过访问 www.nihao.com 后，能够通过 dns 域名解析，访问到 nginx 服务中由 nfs 共享的首页文件，内容为：Very good, you have successfully set up the system. 各个主机能够实现时间同步，并且都开启防火墙来保证服务安装。

作用	系统	IP	主机名	软件
web 服务器	redhat9.5	192.168.121.8	web	nginx，nfs-utils
nfs 服务器	redhat9.5	192.168.121.9	nfs	nfs-utils
DNS 主服务器	redhat9.5	192.168.121.18	dns1	bind
DNS 从服务器	redhat9.5	192.168.121.28	dns2	bind
客户端	redhat9.5	192.168.121.7	client	bind-utils

1.环境准备

web

[root@localhost ~]# hostnamectl hostname web
[root@localhost ~]# nmcli c modify ens160 ipv4.method manual ipv4.addresses 192.168.121.8/24 ipv4.gateway 192.168.121.2 ipv4.dns 223.5.5.5 connection.autoconnect yes
[root@localhost ~]# nmcli c up ens160

nfs

[root@localhost ~]# hostnamectl hostname nfs
[root@localhost ~]# nmcli c modify ens160 ipv4.method manual ipv4.addresses 192.168.121.9/24 ipv4.gateway 192.168.121.2 ipv4.dns 223.5.5.5 connection.autoconnect yes
[root@localhost ~]# nmcli c up ens160

dns1

[root@localhost ~]# hostnamectl hostname dns1
[root@localhost ~]# nmcli c modify ens160 ipv4.method manual ipv4.addresses 192.168.121.18/24 ipv4.gateway 192.168.121.2 ipv4.dns 223.5.5.5 connection.autoconnect yes
[root@localhost ~]# nmcli c up ens160

dns2

[root@localhost ~]# hostnamectl hostname dns2
[root@localhost ~]# nmcli c modify ens160 ipv4.method manual ipv4.addresses 192.168.121.28/24 ipv4.gateway 192.168.121.2 ipv4.dns 223.5.5.5 connection.autoconnect yes
[root@localhost ~]# nmcli c up ens160

client

[root@localhost ~]# hostnamectl hostname client
[root@localhost ~]# nmcli c modify ens160 ipv4.method manual ipv4.addresses 192.168.121.7/24 ipv4.gateway 192.168.121.2 ipv4.dns "192.168.121.18 192.168.121.28" connection.autoconnect yes
[root@localhost ~]# nmcli c up ens160

关闭几台服务器的selinux：

sed -i 's/SELINUX=enforcing/SELINUX=Permissive/g' /etc/selinux/config
setenforce 0

2.时间同步

安装chrony

dnf install chrony -y

启动并设置开机自启动
systemctl start chronyd
systemctl enable chronyd

3.NFS服务器配置

3.1安装NFS服务（192.168.121.9，主机名：nfs）

[root@nfs ~]# dnf install nfs-utils -y

3.2创建共享文件夹并设置权限

[root@nfs ~]# mkdir /nfs/data -p
[root@nfs ~]# cat > /etc/exports <<EOF
> /nfs/data 192.168.121.0/24(rw,sync)
> EOF

3.3创建首页文件

[root@nfs ~]# echo Very good, you have successfully set up the system. > /nfs/data/index.html

3.4启动NFS服务并放开防火墙端口

[root@nfs ~]# systemctl start nfs-server
[root@nfs ~]# systemctl enabel nfs-server

[root@nfs ~]# firewall-cmd --permanent --add-service=nfs
[root@nfs ~]# firewall-cmd --reload

4.Web服务器配置（192.168.121.8，主机名：web）

4.1安装nginx和NFS客户端

[root@web ~]# dnf install nginx -y
[root@web ~]# dnf install nfs-utils -y

4.2挂载NFS共享

[root@web ~]# mkdir -p /usr/share/nginx/html
[root@web ~]# mount 192.168.121.9:/nfs/data /usr/share/nginx/html

4.3配置nginx

[root@web ~]# cat /etc/nginx/nginx.conf

server {
listen 80;
listen [::]:80;
server_name _;
root /usr/share/nginx/html;

# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;

error_page 404 /404.html;
location = /404.html {
}

4.4启动nginx并开放防火墙端口

[root@web ~]# systemctl start nginx
[root@web ~]# systemctl enable nginx
[root@web ~]# firewall-cmd --permanent --add-serverice=http
[root@web ~]# firewall-cmd --reload

5.DNS主服务器配置（192.168.121.18，主机名：dns1）

5.1安装bind

[root@dns1 ~]# dnf install bind -y

5.2配置主配置文件

[root@dns1 ~]# vi /etc/named.conf

options {
listen-on port 53 { 192.168.121.18; };
directory "/var/named";
};

zone "nihao.com" IN{
type master;
file "nihao.com";
}

5.3创建区域文件

[root@dns1 ~]# vi /var/named/nihao.com

$TTL 1D
@ IN SOA @ admin.nihao.com.(
0
1D
2H
3W
2D
)
@ IN NS dns1.nihao.com.
@ IN NS dns2.nihao.com.
www IN A 192.168.121.8

5.4启动bind并放通防火墙端口

directory "/var/named";
};

zone "nihao.com" IN{
type slave;
file "slaves/nihao.com";

master {192.168.121.28； }；
}

6.3启动Bind并开放防火墙端口
