2장. Coherence 설치 및 캐시서버 기동

안녕하세요.

'수상한 김토끼' 입니다.

1장의 소개에 이어 Oracle의 in-memory 캐시 솔루션인 Coherence를 설치해 보겠습니다.

 

이 블로그 글은 미들웨어 경험이 없으신 분들도 쉽게 따라 하실 수 있도록 쉽게 작성하는 것이 목표입니다.

설명을 보고 진행하시다가 궁금하신 내용은 댓글로 문의하시면 가능한 범위 내에서 알려 드리도록 하겠습니다.

1. Coherence 설치

코히어런스를 설치하기 위해서는 x-window 환경이 필요하며 리눅스 서버 등에 putty 등의 터미널로 접속한 경우 일반적인 방법으로는 x-windows가 지원되지 않기 때문에 x-window 환경 구성은 관련 포스팅 '리눅스 x-windows 환경 구성'을 참조해 주세요.

x-window가 지원되는 환경에서 다음 명령으로 설치를 시작합니다.

[coherence@coherence downloads]$ ls
fmw_14.1.1.0.0_coherence.jar  jdk-8u321-linux-x64.tar.gz
[coherence@coherence downloads]$ java -jar fmw_14.1.1.0.0_coherence.jar

[coherence@coherence downloads]$ ls
fmw_14.1.1.0.0_coherence.jar  jdk-8u321-linux-x64.tar.gz
[coherence@coherence downloads]$ java -jar fmw_14.1.1.0.0_coherence.jar
시작 프로그램 로그 파일은 /tmp/OraInstall2022-05-16_02-04-38PM/launcher2022-05-16_02-04-38PM.log입니다.

/tmp/OraInstall2022-05-16_02-04-38PM에서 Oracle Universal Installer 시작을 준비하는 중

 

설치 과정에서 한글은 지원되지 않기 때문에 한글 locale에서는 아래와 같이 설치 GUI창이 깨지게 됨으로

설치 시작 전 Locale을 영문으로 변경해 줍니다.

[coherence@coherence ~]$ export LANG=en_US.UTF-8
[coherence@coherence ~]$ locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

 

영문 locale 변경 후 다시 설치 프로그램을 시작하면 다음과 같은 gui 화면을 볼 수 있습니다.

coherence 설치 gui

설치 경로 지정 후 OK 버튼을 누르면 다음과 같은 설정 화면이 나오며 환경에 맞게 구성 후

Finish 버튼을 눌러 설치를 완료할 수 있습니다.

Auto Updates는 Skip Auto Updates를 선택합니다.

Installation Location은 코히어런스가 설치될 경로를 지정해 줍니다.

저는 /home/coherence14/coherence 경로에 설치를 진행하겠습니다.

Installation Type에서는 Test를 위해 Coherence With Examples를 선택해 줍니다.

Prerequisite Checks에서는 설치에 문제가 되는 부분이 없는지 확인해 줍니다.

예제와 같은 환경이라면 별문제 없이 설치가 가능한 것을 확인할 수 있습니다.

Installation Summary에서는 설치 경로 및 로그파일 위치 디스크 용량, 버전 등을 확인하실 수 있으며

Install 버튼을 눌러 설치를 진행해 줍니다.

Install 버튼을 누르면 다음과 같이 설치가 완료됩니다.

Finish버튼을 눌러서 설치를 종료해도 되고 Next버튼을 눌러 설치 상세정보를 확인도 가능합니다.

설치가 완료되었습니다. Finish 버튼을 눌러 설치를 종료합니다.

2. Coherence 설치경로 둘러보기

Installer 종료 후 설치 경로에서 다음과 같이 설치된 내역 확인이 가능합니다.

[coherence@coherence coherence14c]$ ls -l
total 4
drwxr-x---.  7 coherence coherence  89 May 11 09:56 coherence
drwxr-x---. 16 coherence coherence 248 May 11 09:57 inventory

-rw-r-----.  1 coherence coherence 135 May 11 09:57 oraInst.loc
drwxr-x---.  8 coherence coherence 129 May 11 09:57 oui

 

/home/coherence14c/coherence 경로가 코히어런스의 홈 디렉터리로 코히어런스는

COHERENCE_HOME이란 환경변수에 /home/coherence14c/coherence 경로를 지정하여 사용하게 됩니다.

 

이 디렉터리는 다음과 같은 구조로 되어 있습니다.

[coherence@coherence coherence]$ ls -l
total 8
drwxr-x---. 2 coherence coherence  189 May 11 10:07 bin
drwxr-x---. 3 coherence coherence   42 May 11 09:56 doc

drwxr-x---. 5 coherence coherence   54 May 11 09:56 plugins
-rw-r-----. 1 coherence coherence  100 Nov 21  2019 product.xml

COHERENCE_HOME/bin 경로로 이동하여 코히어런스 캐시 서버를 기동해 줍니다.

[coherence@coherence bin]$ ls -l
total 32

방화벽 설정등 멀티캐스트 통신이 불가능한 경우 아래와 같이 기동 오류가 발생됩니다.

멀티캐스트 오류가 반복되다 Timeout에 걸려 실행이 실패하고 말았습니다.

root 사용자로 방화벽 설정(이 글에서는 방화벽 disable)을 해 줍니다.

 

firewalld 상태를 확인해 보니 coherence에서 멀티캐스트 통신이 실패했던 로그도 확인되네요.

 

실제 운영환경에서는 멀티캐스트 관련 부분 설정을 추가 해 주셔야 합니다.

지금은 테스트 목적임으로 편의상 방화벽을 내리고 작업하도록 하겠습니다.

여기까지 기본적인 코히어런스 설치 및 캐시 서버 기동까지 진행해 보았습니다.

다음 장에서는 캐시서버 기동 및 설치시 제공 된 예제를 실행해 보도록 하겠습니다.
