Oracle Linux paigaldamine

Virtuaalmasina valmistamine

• RAM 512MB
• HDD 12GB Dynamic
• 2 Võrgukaarti
  • eth0 - NAT (lubab Interneti pääseda)
  • eth1 - Host only (ühendamine teise virtuaalmasinaga)

Installeerimine

Juhendis kasutatakse Oracle Linux Server 6.3. Allalaadimise link on siin: http://www.oracle.com/technetwork/server-storage/vm/downloads/index.html (seal on vaja registreerida)

Installerimine käigus:

1. Buutides isolt vali "Install an existing system"

2. Aknas "testing the media" , vajutage skip

3. Vali keel ja klaviatuuri layout

4. Vali time zone

5. Sisesta root kasutaja parooli

6. Partitsiooni muutmine

7. Peale partitsiooni muutmine, automaatselt tuleb package installimine

8. Installerimine lõpeb, süsteemi reboot

Võrgukaartide seadistamine

On vaja muuda 2 faili:

1. /etc/sysconfig/network-scripts/ifcfg-eth0 - NAT

2. /etc/sysconfig/network-scripts/ifcfg-eth1 - Host Only

eth0 konfigureerimine:

 vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"
BOOTPROTO="dhcp"
HWADD="08:00:27:9E:F4:FC"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="441d9faa-078f-405d-9f30-45849ca8c8f4"

eth1 konfigureerimine:

vi /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE="eth1"
BOOTPROTO="static"
HWADDR="08:00:27:22:BB:1D"
NM_CONTROLLED="yes"
ONBOOT="yes"
IPADDR=192.168.56.205
NETMASK=255.255.255.0
TYPE="Ethernet"
UUID="f477120f-5ebf-46c3-90db-fa58d05ab02c"

Lõpuks tuleb võrgu restarti teha:

service network restart

DNS (bind9)

Paigaldamine

Paigaldatakse DNS serveri käsuga

yum install bind

Konfigureerimine

• Muuda 'options' osa named.conf failis

vi /etc/named.conf

Muuda seal read listen-on port 53, sisesta 'any'; allow-query, sisesta 'any'; lisa rea allow-query-cache { any; }

options {
	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";
	allow-query     { any; };
	allow-query-cache { any; };
	
	dnssec-enable yes;
	dnssec-validation yes;
	dnssec-lookaside auto;

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

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

• Lisa faili named.conf lõppus enda teenindatavad domeeni tsoonid

vi /etc/named.conf

Teenindatavad domeeni tsoonid

zone "students.ee" IN {
	type master;
	file "/var/named/students.ee";
};


zone "56.168.192.in-addr.arpa." IN {
        type master;
        file "/var/named/56.168.192.in-addr.arpa";
};

• Tsoonide kirjeldused

Tsoonide failid asuvad

/var/named kaustas

Iga tsooni kohta loo 2 faili, kirjete fail ja reverse fail
Tsooni fail nimega students.ee näeb välja järgnev:

vi /var/named/students.ee

$TTL 3H
@		IN SOA	ns.students.ee.	root.students.ee. (
						11	; serial
						1D	; refresh
						1H	; retry
						1W	; expire
						3H )	; minimum
;NS
students.ee.	IN NS	ns.students.ee.

;HOSTS
ns	                IN A	        192.168.56.205
www.students.ee.	IN CNAME	students.ee.
students.ee.	        IN A	        192.168.56.205
students.ee.            IN MX           10 mail.students.ee.
mail.students.ee.       IN A            192.168.56.206

Reverse tsooni fail nimega 56.168.192.in-addr.arpa näeb välja järgnev:

vi /var/named/56.168.192.in-addr.arpa

$TTL 3H
@		IN SOA	ns.students.ee.	root.students.ee. (
						9	; serial
						1D	; refresh
						1H	; retry
						1W	; expire
						3H )	; minimum
;
56.168.192.in-addr.arpa.       IN      NS      ns.students.ee.
205.56.168.192.in-addr.arpa.   IN      PTR     ns.students.ee.        
206.56.168.192.in-addr.arpa.   IN      PTR     mail.students.ee.
