2024.7.24（反向解析、时间同步、主从架构）

[root@client ~]# systemctl stop NetworkManager

[root@client ~]# systemctl disable NetworkManager

一、配置反向解析

1、配置zone文件

[root@dns named]# vim /etc/named.rfc1912.zones

[root@dns named]# ls
[root@dns named]# cp -p named.loopback 192.168.8.zone
[root@dns named]# ls -l

[root@dns named]# vim 192.168.8.zone

2、检查配置文件

[root@dns named]# named-checkconf /etc/named.rfc1912.zones
[root@dns named]# named-checkzone 192.168.8.zone 192.168.8.zone
zone 192.168.8.zone/IN: loaded serial 0
OK

3、重启服务

[root@dns named]# systemctl restart named

4、临时更换

[root@client ~]# echo nameserver  192.168.8.135 > /etc/resolv.conf
