### 问题 ###

#### 问题来啦~`systemctl restart named` ####

#### 重启`named`服务失败 ####

[root@centos7-9-2009-zsc named]# systemctl restart named

#### 解决方法 ####

##### \`named-checkconf -z /etc/named.conf\`\` #####

### 修改错处后就成功啦 ###

![成功][55f5d939145e42c5ba70fcb3ed714ae8.png]

### 修改/配置DNS ###

安装及配置bind服务程序：

yum install bind-chroot -y

三个关键文件：

主配置文件（/etc/named.conf）

区域配置文件（/etc/named.rfc1912.zones）

数据配置文件目录（/var/named）

vim /etc/named.conf

修改两个参数：

listen-on port 53 \{ any ; \}; //服务器上所有IP地址均可提供DNS域名解析服务

allow-query \{ any; \}; //允许所有人对本服务器发送DNS查询请求

例如进行正向解析实验中：

第一步：编辑区域配置文件：vim /etc/named.rfc1912.zones（按照模板添加自己的域名解析信息）

第二步：编辑数据配置文件:可以先从/var/named目录中复制一份正向解析的模板文件，需要-a参数

命令如下：cd /var/named

cp   -a  named.localhost     文件名（与区域配置文件中一致）
    
                   vim   文件名    //添加自己的数据
