一、所有主机初始化

二、135、136服务器，部署DNS调度服务器

1、更改主机主从DNS服务器的主机名称

2、安装bind软件、修改主配置文件

3、修改区域配置文件 

4、修改数据文件

5、启动named服务、修改网卡信息

6、解析

7、双网卡的话记得注释以下内容、注释完不能ifdown ens33否则会刷新文件取消注释

8、从服务器配置

---

一、所有主机初始化

[root@localhost ~] systemctl stop firewalld
[root@localhost ~] setenforce 0
[root@localhost ~] iptables -F

二、135、136服务器，部署DNS调度服务器

1、更改主机主从DNS服务器的主机名称

[root@ansible ~]# hostnamectl set-hostname DNS1
[root@ansible ~]# bash                                                                                
[root@dns1 ~]#    
[root@agent ~]# hostnamectl set-hostname DNS2
[root@agent ~]# bash
[root@dns2 ~]# 

2、安装bind软件、修改主配置文件

[root@dns1 ~]# yum -y install bind
[root@lb1 ~]# vim /etc/keepalived/keepalived.conf  
12 options {13         listen-on port 53 { 192.168.147.135; };14         listen-on-v6 port 53 { ::1; };15         directory       "/var/named";16         dump-file       "/var/named/data/cache_dump.db";17         statistics-file "/var/named/data/named_stats.txt";18         memstatistics-file "/var/named/data/named_mem_stats.txt";19         recursing-file  "/var/named/data/named.recursing";20         secroots-file   "/var/named/data/named.secroots";21         allow-query     { any; };22         allow-transfer  { 192.168.147.136; }

3、修改区域配置文件 

[root@dns1 ~]# vim /etc/named.rfc1912.zones 
zone "skl.com" IN {type master;file "skl.localhost";allow-update { none; };
};

4、修改数据文件

[root@dns1 named]# vim skl.localhost
$TTL 1D
@       IN SOA  skl.com. rname.invalid. (0       ; serial1D      ; refresh1H      ; retry1W      ; expire3H )    ; minimumNS      dns.skl.com.
dns     A       192.168.147.135
www     A       192.168.147.254
www     A       192.168.147.253

5、启动named服务、修改网卡信息

[root@dns1 named]# systemctl start named
[root@dns1 named]# vim /etc/sysconfig/network-scripts/ifcfg-ens33
[root@dns1 named]# ifdown ens33&&ifup ens33

6、解析

[root@DNS1 ~]# nslookup 
> www.skl.com
Server:		192.168.147.135
Address:	192.168.147.135#53Name:	www.skl.com
Address: 192.168.147.254
Name:	www.skl.com
Address: 192.168.147.253

7、双网卡的话记得注释以下内容、注释完不能ifdown ens33否则会刷新文件取消注释

[root@DNS1 ~]# vim /etc/resolv.conf
# Generated by NetworkManager
#nameserver 180.76.76.76
#nameserver 223.5.5.5
nameserver 192.168.147.135

8、从服务器配置

[root@AS2 ~]# vim /etc/named.conf
listen-on port 53 { 192.168.147.136; };allow-query     { any; };[root@AS2 ~]# vim /etc/named.rfc1912.zones
zone "skl.com" IN {type slave;file "slaves/skl.localhost";allow-update { 192.168.147.135; };[root@DNS2 ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens33  
DNS1=192.168.147.135     #末行添加解析服务器地址（从DNS服务器IP）[root@AS2 ~]# nslookup 
> www.skl.com
Server:		192.168.147.135
Address:	192.168.147.135#53Name:	www.skl.com
Address: 192.168.147.253
Name:	www.skl.com
Address: 192.168.147.254
