云计算之kubernetes系列——配置本地dns服务并关联kube-dns

一，背景
    因为k8s集群以及web服务测试，每次使用/etc/hosts配置或者写ip都不太好，所以决定搭建dns服务器做域名解析，后期可以做k8s-kube-dns的父dns服务器。
二，搭建
    1. 服务器
        dnsserver   192.168.89.128
    2. 安装dns软件包
        yum -y install bind bind-chroot bind-utils
    3. 修改dns配置
        vim /etc/named.conf
            options {
                /*此处改成any*/
                listen-on port 53 { any; };
                listen-on-v6 port 53 { ::1; };
                directory  "/var/named";
                dump-file  "/var/named/data/cache_dump.db";
                statistics-file "/var/named/data/named_stats.txt";
                memstatistics-file "/var/named/data/named_mem_stats.txt";
                recursing-file  "/var/named/data/named.recursing";
                secroots-file   "/var/named/data/named.secroots";
                /*此处改成any*/
                allow-query     { any; };

                recursion yes;

                dnssec-enable yes;
                dnssec-validation yes;

                /* Path to ISC DLV key */
                bindkeys-file "/etc/named.root.key";

                managed-keys-directory "/var/named/dynamic";

                pid-file "/run/named/named.pid";
                session-keyfile "/run/named/session.key";
            };

            logging {
                    channel default_debug {
                            file "data/named.run";
                            severity dynamic;
                    };
            };

            zone "." IN {
                type hint;
                file "named.ca";
            };
            /*此zone做测试域名解析使用*/
            zone "ktz.com" IN {
                type master;
                file "ktz.com.zone";
            };
            /
