kubernetes集群安装公共服务 DNS
第一步:
yum -y install bind
2。1
vim /etc/named.conf
改2个地方:
添加 any
# cat -n /etc/named.conf
1 //
2 // named.conf
3 //
4 // Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
5 // server as a caching only nameserver (as a localhost DNS resolver only).
6 //
7 // See /usr/share/doc/bind*/sample/ for example named configuration files.
8 //
9 // See the BIND Administrator's Reference Manual (ARM) for details about the
10 // configuration located in /usr/share/doc/bind-{version}/Bv9ARM.html

12 options {
13 listen-on port 53 { 127.0.0.1;any; }; 添加any;
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 { localhost;any; }; 添加any;
2.2 添加域名注册
vim /etc/named.rfc1912.zones
# tail -5 /etc/named.rfc1912.zones
zone "msb.com" IN {
type master;
file "msb.com.zone";
allow-update { none; };
};
2.3 正向查询区域文件
# cd /var/named
# cp -p named.localhost msb.com.zone
# # vim msb.com.zone
# cat msb.com.zone
$TTL 1D
@ IN SOA msb.com admin.msb.com. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
@ NS ns.msb.com.
ns A 192.168.10.145
harbor A 192.168.10.146
三、 开启服务
# systemctl enable --now named
# vim /etc/sysconfig/network-scripts/ifcfg-ens33
# tail -5 /etc/sysconfig/network-scripts/ifcfg-ens33
IPADDR="192.168.10.145"
PREFIX="24"
GATEWAY="192.168.10.2"
DNS1="192.168.10.145" 添加本地DNS
DNS2="119.29.29.29"
阿里云 的配置:
五、 域名解析 验证
# nslookup
> server 输入server,查看本地DNS server服务器
Default server: 192.168.10.145
Address: 192.168.10.145#53
Default server: 119.29.29.29
Address: 119.29.29.29#53
> harbor.msb.com 输入harbor.msb.com域名,用于解析
Server: 192.168.10.145
Address: 192.168.10.145#53
Name: harbor.msb.com
Address: 192.168.10.146
或者:
dig -t a harbor.msb.com @10.0.0.234
安装 nslookup
yum provides * bin nslookup
六. k8s 集群主机网络 配置DNS
# vim /etc/sysconfig/network-scripts/ifcfg-ens33
# tail -5 /etc/sysconfig/network-scripts/ifcfg-ens33
IPADDR="192.168.10.14X"
PREFIX="24"
GATEWAY="192.168.10.2"
DNS1="192.168.10.145" 添加本地DNS
DNS2="119.29.29.29"
验证:
ping www1.kattgatt.cn
七 . 后期添加服务 配置DNS
后期,我们 添加自己服务后,怎么 配置域名来访问, 我们可以在DNS 中进行 域名与IP 绑定。
后期,我们在部署服务的时候, 需要用域名进行访问。
怎么改呢?
在DNS 服务器上,修改 正向查询的文件。
vim /var/named/baimei.com.zone
重启 dns 服务
systemctl restart named
之后我们访问 10.0.0.70 的服务就可以这样访问
curl www1.baimei.com
你学会了吗?
vmware 中 配置一下 dns ,然后本机可以不用配置Host 访问应用
