[Oracle]Part 2)쉽고 완벽한 Weblogic과 Webtier 설치하기

by · 2023년 10월 12일

일반적으로 Oracle WebLogic Server(wls)는 Java EE 애플리케이션을 실행하고 관리하는 데 사용되며, Oracle Webtier(ohs, Oracle HTTP Server)는 정적 및 동적 웹 콘텐츠를 서비스하고 보안 기능을 제공하여 웹 애플리케이션 환경을 보완합니다. 이 두 제품은 혼합하여 사용되어 Java 애플리케이션을 실행하고 프론트 엔드 웹 서버로부터 요청을 처리하는 효율적인 웹 애플리케이션 스택을 구축하는 데 도움을 줍니다. Oracle Database 11gR2가 설치된 VM(oel7.8)에 wls와 ohs를 설치하도록 하겠습니다.

  1. Part 1. 설치 준비하기
  2. Part 2. ohs(Oracle HTTP Server 설치하기
  3. Part 3. wls(Weblogic Server) 설치하기
  4. Part 4. 응용 프로그램 배치
  5. Part 5. 클러스터 구성
  6. Part 6. 데이터 소스 연결

1. ohs를 silent mode로 설치하기

silent 모드로 설치하기 위해서는 응답 파일(ohs_install.rsp)와 Oracle Inventory 위치를 나타내는 파일(ohs_oraInst.loc)이 필요합니다. Part 1)생성한 webtier 사용자로 접속해서 진행해야 합니다.
  • “ohs_install.rsp” 파일 생성하기 
    [webtier@oel7u8 ~]$ cd /oracle/sw/ohs
[webtier@oel7u8 ohs]$ vi ohs_install.rsp
    [ENGINE]
Response File Version=1.0.0.0.0
[GENERIC]
ORACLE_HOME=/oracle/fmw/ohs
INSTALL_TYPE=Standalone HTTP Server (Managed independently of WebLogic server)
DECLINE_SECURITY_UPDATES=true
SECURITY_UPDATES_VIA_MYORACLESUPPORT=false
  • “ohs_oraInst.loc” 파일 생성하기 
    [webtier@oel7u8 ohs]$ vi ohs_oraInst.loc
    inventory_loc=/oracle/oraInventory/ohs
inst_group=webtier
  • silent mode로 webtier 설치하기 및 결과 확인
    옵션에 지정된 파일은 절대 경로로 설정해야 합니다. 
    [webtier@oel7u8 ohs]$ ./fmw_12.2.1.4.0_ohs_linux64.bin -silent -force \
> -responseFile /oracle/sw/ohs/ohs_install.rsp \

    selectTemplate('Oracle HTTP Server (Standalone)', '12.2.1.3.0')
loadTemplates()

cd('SystemComponent/ohs1')
# WANTED_OHS_COMPONENT_NAME
set('Name','comp1')    "◀ 컴포넌트 등록"

cd('/SecurityConfiguration/base_domain')
set('NodemanagerUsername','webtier')
set('NodemanagerPasswordEncrypted','oracle1234')

cd('/')
# INSTALL_DOMAIN_POSITION
writeDomain('/sw/webtier/domains/orcl_domain')  "◀ 도메인 설치 경로 등록"
closeTemplate()
exit()
