centos搭建DNS服务器_bind9

1.更换清华源镜像

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#

2.yum安装bind9

yum install bind*

3.修改配置文件

/etc/named.conf

//在options内修改如下

listen-on port 53 { 192.168.x.x; };　　//修改ip为本机ip 非环回地址

// listen-on-v6 port 53 { ::1; };   注释掉ipv6

//添加转发dns优先

forward first;
forwarders {61.139.2.69;119.6.6.6;};

//在logging添加日志如下

logging {
channel default_debug {
file "data/named.run" versions 2000 size 50M;　　//2000个文件  每个50M
severity info;
print-category yes;
print-time yes;
buffered yes;
};
category queries {　　//将查询信息计入日志
default_debug;
};
};

4.设置开机启动

systemctl start named

systemctl enable named
