chmod 640 /var/named/106.17.172.zone  
chown root:named /var/named/106.17.172.zone  
#service named start 
 
从DNS服务器: 
#yum install bind 
#cp /etc/named.conf /etc/named.conf.bak 
#vim /etc/named.conf 
options { 
        directory "/var/named"; 
}; 
 
zone "geasyheart.com" IN   { 
        type slave; 
        file "slaves/geasyheart.com.zone"; 
        masters { 192.168.122.104; }; 
}; 
 
zone "122.168.192.in-addr-arpa" IN { 
        type slave; 
        file "slaves/192.168.122.zone"; 
        masters { 192.168.122.104; }; 
}; 
 
#chown root.named /etc/named.cof 
#chmod 640 /etc/named.conf 
#service named start 
就会完成主从DNS传送 （更多细节参考文档说明）

//注意：如果DNS的记录被更新了，那么版本号应该更新；；；这个需要注意；；

    缺失模块。
    1、请确保node版本大于6.2
    2、在博客根目录（注意不是yilia根目录）执行以下命令：
    npm i hexo-generator-json-content --save

    3、在根目录_config.yml里添加配置： 

      jsonContent:
    meta: false
    pages: false
    posts:
      title: true
      date: true
      path: true
      text: false
      raw: false
      content: false
      slug: false
      updated: false
      comments: false
      link: false
      permalink: false
