매번 느끼는것이지만 버전이 업될때마다 조금씩 조금씩 설치 방법이 달라지고 있습니다.

최근 SAP BusinessObject BI 4.2 + Lumira 4.2와 S4HANA 1809 설치하면서 고전을 좀 했습니다.

특히 S4HANA의 경우 설치 잘 되다가 중간에 에러 툭터지면서 FQDN (서버 이름)를 문제 삼아 더 진행이 안되는 상황도 발생 했고요.

S4HANA의 경우 SUSE를 애용하는데요.

제가 사용을 잘못하는건지 Hostname과 Domain 이름을 어드민툴을 이용해 설정해도, 어느 순간 바뀌어 있고 해서 이상 증상을 겪었습니다.

그래서 수작업으로 하는 방법을 찾아 내용 올립니다.

·         Hostname -> oracleuser

·         Domain -> 도메인.com

1.   Modify hostname file

With root permissions, edit file /etc/hostname.

oracleuser@linux:~> vi /etc/hostname

Write the hostname for the server.

oracleuser

2.   Modify hosts file

Check your network interfaces to find out the IP address for your Ethernet network (eth1).

oracleuser@linux:~> ifconfig
eth1      Link encap:Ethernet  HWaddr 08:00:27:91:22:4E
          inet addr:192.168.0.2  Bcast:10.0.2.255  Mask:255.255.255.0
          inet6 addr: fe80::a00:27ff:fe91:224e/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:234 errors:0 dropped:0 overruns:0 frame:0
          TX packets:266 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:22687 (22.1 Kb)  TX bytes:28332 (27.6 Kb)

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:69 errors:0 dropped:0 overruns:0 frame:0
          TX packets:69 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1
          RX bytes:4630 (4.5 Kb)  TX bytes:4630 (4.5 Kb)

With root permissions, edit file /etc/hosts.

oracleuser@linux:~> vi /etc/hosts

Set your IP address for Ethernet network with your FQDN:

o    192.168.0.2  oracleuser.도메인.com  oracleuser

#
# hosts         This file describes a number of hostname-to-address
#               mappings for the TCP/IP subsystem.  It is mostly
#               used at boot time, when no name servers are running.
#               On small systems, this file can be used instead of a
#               "named" name server.
# Syntax:
#
# IP-Address  Full-Qualified-Hostname  Short-Hostname
#

127.0.0.1       localhost
192.168.0.2       oracleuser.도메인.com       oracleuser

# special IPv6 addresses
::1             localhost ipv6-localhost ipv6-loopback

fe00::0         ipv6-localnet

ff00::0         ipv6-mcastprefix
ff02::1         ipv6-allnodes
ff02::2         ipv6-allrouters
ff02::3         ipv6-allhosts

Restart rcnetwork services.

oracleuser@linux:~> rcnetwork restart

3.   Verification

Check your parameters.

oracleuser@linux:~> hostname --short
oracleuser
oracleuser@linux:~> hostname --domain
도메인.com
oracleuser@linux:~> hostname --fqdn
oracleuser.도메인.com
oracleuser@linux:~> hostname --ip-address
192.168.0.2

끝.
