k8s(二)-bind的安装

作者:互联网

1.基础包的安装(zyjc7-11上)

yum install -y wget net-tools telnet tree nmap sysstat lrzsz dos2unix bind-utils

2、安装bind

yum -y   install   bind

3、修改配置

vim  /etc/named.conf

listen-on port 53 { 10.4.7.11; };    #修改为本机地址
allow-query     { any; };            #主机都可以访问
forwarders  { 223.5.5.5; };          # 办公网上一级的DNS,(生产写运营商dns)
recursion yes;                       # dns采用递归的查询
 dnssec-enable no;                   # 关闭,节省资源(生产可能不需要关闭)
 dnssec-validation no;               # 关闭,节省资源,不做互联网认证

vim  /etc/named.rfc1912.zones     在文件最后插入

zone "host.com" IN {
        type master;
        file "host.com.zone";
        allow-update { 10.4.7.11; };
};

zone "od.com" IN {
        type master;
        file "od.com.zone";
        allow-update { 10.4.7.11; };
};

vim    /var/named/host.od.com

$ORIGIN host.com.
$TTL 600        ; 10 minutes
@       IN SOA  dns.host.com. dnsadmin.host.com. (
                                2022032501 ; serial
                                10800      ; refresh (3 hours)
                                900        ; retry (15 minutes)
                                604800     ; expire (1 week)
                                86400      ; minimum (1 day)
                                )
                        NS   dns.host.com.
$TTL 60 ; 1 minute
dns                A    10.4.7.11
zyjc7-11           A    10.4.7.11
zyjc7-12           A    10.4.7.12
zyjc7-21           A    10.4.7.21
zyjc7-22           A    10.4.7.22
zyjc7-200          A    10.4.7.200

# 过期时间2019.12.09+01序号

# 区域授权文件的开始,OSA记录,dnsadmin.host.com为邮箱

2022032501 # 安装的当天时间

vim  /var/named/od.com.zone

$ORIGIN od.com.
$TTL 600        ; 10 minutes
@               IN SOA  dns.od.com. dnsadmin.od.com. (
                                2022032501 ; serial
                                10800      ; refresh (3 hours)
                                900        ; retry (15 minutes)
                                604800     ; expire (1 week)
                                86400      ; minimum (1 day)
                                )
                                NS   dns.od.com.
$TTL 60 ; 1 minute
dns                A    10.4.7.11

4、检查配置是否修改正确

 named-checkconf
named-checkzone "host.com" /var/named/host.com.zone
named-checkzone "od.com" /var/named/od.com.zone
 chown root:named /var/named/host.com.zone
 chown root:named /var/named/od.com.zone
 chmod 640 /var/named/host.com.zone
 chmod 640 /var/named/od.com.zone

5、启动服务,开机启动,并检测

systemctl  enable  --now  named
dig   -t  A  zyjc7-12.host.com  @10.4.7.11  +short
