Linux builds DNS master-slave synchronization

1 Build the DNS master-slave server.

1.1 Environmental Requirements:

Centos 6.5 x86_64

1.2 Hardware configuration:

Name

IP planning

Cpu

Memory

Hard disk

Primary server

192.168.0.24

4 cores

8G

80G

From the server

192.168.0.34

4 cores

8G

80G

1.3 Package Installation:

[email protected] ~]# Yum install-y bind Bind-chroot Bind-utlis

1.4 Configuration files:

/etc/named.conf bind service master configuration file.

/var/named/zone file.

1.5 Copy profile Template:

[Email protected] ~]# cp-rv/usr/share/doc/bind-9.8.2/sample/etc/*/var/named/chroot/etc/

[Email protected] ~]# cp-rv/usr/share/doc/bind-9.8.2/sample/var/*

1.6 To modify the master configuration file:

[Email protected] ~]# vi/var/named/chroot/etc/named.conf

Options

{

    // Put files that named is allowed to write in the data/ directory:    directory               "/var/named";           // "Working" directory    dump-file               "data/cache_dump.db";    statistics-file         "data/named_stats.txt";    memstatistics-file      "data/named_mem_stats.txt";    //listen-on port 53     { any; };    listen-on port 53       { any; };    //listen-on-v6 port 53  { any; };    listen-on-v6 port 53    { ::1; };    allow-query             { any; };    allow-query-cache       { any; };    forwarders             { 10.0.0.1;114.114.114.114; };    recursion yes;    dnssec-enable yes;    dnssec-validation yes;

};

Zone "zabbix.73go.cn" {

  type  master;  file "zabbix.73go.cn.zone";

};

1.7 Modifying Zone files:

[Email protected] named]# cd/var/named/chroot/var/named

[email protected] named]# cat Zabbix.73go.cn.zone

$TTL 1D

@ in SOA @ rname.invalid. (

                                    0       ; serial                                    1D      ; refresh                                    1H      ; retry                                    1W      ; expire                                    3H )    ; minimum    NS      @    A       127.0.0.1    AAAA    ::1    IN    A  192.168.0.236

1.8 Syntax Check:

[Email protected] named]# named-checkconf/var/named/chroot/etc/named.conf

[Email protected] named]# Named-checkzone linuxcast.net linuxcast.net.zone

1.9 Restart Service:

[Email protected] named]# service named Reload

Or

[Email protected] named]# service named restart

2 Configuration from server:

2.1 Package Installation:

[email protected] ~]# Yum install-y bind Bind-chroot Bind-utlis

2.2 Copy profile Template:

[Email protected] ~]# cp-rv/usr/share/doc/bind-9.8.2/sample/etc/*/var/named/chroot/etc/

2.3 Changing the server from the configuration file

[Email protected] etc]# vi/var/named/chroot/etc/named.conf

Options

{

    // Put files that named is allowed to write in the data/ directory:    directory               "/var/named";           // "Working" directory    dump-file               "data/cache_dump.db";    statistics-file         "data/named_stats.txt";    memstatistics-file      "data/named_mem_stats.txt";    //listen-on port 53     { any; };    listen-on port 53       { any; };    //listen-on-v6 port 53  { any; };    listen-on-v6 port 53    { ::1; };    allow-query             { any; };    allow-query-cache       { any; };    forwarders             { 10.0.0.1;114.114.114.114; };    recursion yes;    dnssec-enable yes;    dnssec-validation yes;

};

Zone "zabbix.73go.cn" {

  type  slave; masters{ 192.168.0.24; };  file "slaves/zabbix.73go.cn.zone";

};

2.4 Restart Service:

[Email protected] named]# service named Reload

Or

[Email protected] named]# service named restart

2.5 Guaranteed Directory Permissions:

[email protected] named]# LL

Drwxrwxrwx. 2 named named 4096 July 5 17:55 Slaves

2.6 View the Sync zone file.

[Email protected] slaves]# cat/var/named/chroot/var/named/slaves
