风哥提示：
Part01-DNS服务器配置
1.1 BIND DNS部署
[root@fgedu-dns ~]# yum install -y bind bind-utils
[root@fgedu-dns ~]# systemctl enable named –now
# 配置主配置文件
[root@fgedu-dns ~]# cat > /etc/named.conf << 'EOF'
options {
listen-on port 53 { 127.0.0.1; 192.168.1.0/24; };
directory "/var/named";
allow-query { any; };
recursion yes;
};
zone "fgedu.net.cn" IN {
type master;
file "fgedu.net.cn.zone";
};

type master;
file "1.168.192.zone";
};

Part02-DHCP服务器配置
2.1 DHCP服务部署
[root@fgedu-dhcp ~]# yum install -y dhcp-server
# 配置DHCP
[root@fgedu-dhcp ~]# cat > /etc/dhcp/dhcpd.conf << 'EOF'

fixed-address 192.168.1.100;
}
EOF
[root@fgedu-dhcp ~]# systemctl enable dhcpd --now
Part03-VPN服务配置
3.1 OpenVPN部署
[root@fgedu-vpn ~]# yum install -y openvpn easy-rsa
# 初始化PKI
[root@fgedu-vpn ~]# mkdir -p /etc/openvpn/easy-rsa
[root@fgedu-vpn ~]# cp -r /usr/share/easy-rsa/3/* /etc/openvpn/easy-rsa/
[root@fgedu-vpn ~]# cd /etc/openvpn/easy-rsa
[root@fgedu-vpn easy-rsa]# ./easyrsa init-pki
[root@fgedu-vpn easy-rsa]# ./easyrsa build-ca nopass
[root@fgedu-vpn easy-rsa]# ./easyrsa build-server-full server nopass
[root@fgedu-vpn easy-rsa]# ./easyrsa gen-dh
# 配置OpenVPN服务器
