bind主从配置

一、环境
1、系统版本

CentOS release 6.5 (Final)

2、软件版本

bind-libs-9.8.2-0.37.rc1.el6.x86_64bind-9.8.2-0.37.rc1.el6.x86_64
bind-utils-9.8.2-0.37.rc1.el6.x86_64

3、地址

10.10.66.121  主
10.10.66.122  从

二、安装配置
1、安装（主从一样）

yum -y install bind-libs bind-utils bind

2、建立相关目录

mkdir /data/named/
mkdir /data/log/named/
chown named:named /data/named/ -R
chown named:named /data/log/named/ -R

2、配置
A、拷贝配置文件

cp -r /var/named/* /data/named/

B、撰写主配置文件/etc/named.conf（主、从）

acl wx {
10.57.66.0/24;
};
acl zw {
10.10.2.0/24;
};
options {
listen-on port 53 { any; };
directory       "/data/named";
dump-file       "/data/named/data/cache_dump.db";
statistics-file "/data/named/data/named_stats.txt";
memstatistics-file "/data/named/data/named_mem_stats.txt";
dnssec-enable no;
allow-query { wx;zw;   };
allow-transfer { 10.10.66.122; }; #从库无需配置此参数
also-notify { 10.10.66.122; };       #从库无需配置此参数
recursion yes;
notify yes;                                  #从库无需配置此参数
tcp-clients 1000;
};

controls{
inet 0.0.0.0 port 953
allow { localhost; } ;
};
logging {
category "default" { "normal"; };
category "general" { "normal"; };
category "database" { "normal"; };
category "security" { "normal"; };
category "config" { "normal"; };
category "resolver" { "normal"; };
category "xfer-in" { "normal"; };
category "xfer-out" { "normal"; };
category "notify" { "normal"; };
category "client" { "normal"; };
category "unmatched" { "normal"; };
category "network" { "normal"; };
category "update" { "normal"; };
category "queries" { "normal"; };
category "dispatch" { "normal"; };
category "dnssec" { "normal"; };
category "lame-servers" { "normal"; };
channel "normal" {
file "/data/log/named/normal.log" versions 3 size 200m;
severity debug 0;
print-time yes;
print-category yes;
print-severity yes;
};
};

zone "." IN {
type hint;
file "named.ca";
};

include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

C、在/etc/named.rfc1912.zones添加zone区域 （主）

zone "cmredis.com"  {
type master;
file "cmredis.com.zone";
allow-update { none; };
};

D、在/etc/named.rfc1912.zones添加zone区域 （从）

zone "cmredis.com"  {
type slave;
masters {10.10.66.121;};
file "slaves/cmredis.com.zone";
allow-update { none; };
};

E、撰写cmredis.com.zone文件（主）

vim /data/named/cmredis.com.zone
$TTL  60
@  IN SOA cmredis.com. root (
53              ; serial (d. adams)
3H              ; refresh
15M             ; retry
1W              ; expiry
1D )            ; minimum

IN      NS  ns.cmredis.com.
@               IN      NS  dns2.cmredis.com.
ns              IN      A   127.0.0.1
dns             1200            IN      A               10.10.66.121
dns2            1200            IN      A               10.10.66.122

三、检查配置文件、启动服务（主从）
1、检查配置

named-checkzone cmredis.com.zone /data/named/cmredis.com.zone
/etc/init.d/named configtest

2、启动服务

/etc/init.d/named start
chkconfig named on

PS:
在主库上添加删除A记录，从库没有同步过去，把从库的zone文件删掉，重启才重新拉取一份，原来是在master修改了记录时一定要修改serial! 只有master Serial大于slave时 slave才会同步
