027. Raspberry Pi 라즈베리 파이 - Apache2(v2.4.10) Tomcat 연동 (mod_jk)

이전에 Apache2와 Tomcat9 을 설치 했었는데 둘을 연동하려합니다

 

사실 Tomcat포트를 80으로 변경하면 포트번호 없이도 접속할 수 있겠지만

보통 JSP개발은 tomcat만 이용하고 운영할때는 apache + tomcat이 정석으로 보면됩니다

WEBTOBE + JEUS 같은 느낌이랄까나...

 

각설하고

apache 설치를 안했다면 http://zelkun.tistory.com/69 여기를

tomcat 설치를 안했다면 http://zelkun.tistory.com/68 여기를 참고합니다

변경사항으로는 tomcat을 /usr/local/tomcat9 으로 이동했고

pi/tomcat9으로 링크를 걸어놨으니 참고하시길..

예전에 데스크탑 서버에다 apache를 직접설치하고 설정도 해보고 해서 그대로

pi에다가 적용해봤었는데 둘이 따로 놀아서 GG했던 경험이...

• mod_jk 설치

apt-get를 이용하면 필수lib 설치등의 절차가 생략되는 장점이 있죠 명령어하나로 다 된다니 신세경.. (apache2.4.9 직접 설치하다 빡친경험이 있는 1인..)

tomcat-connetor를 설치했으니 이제 apach2.conf를 수정합니다

 

• apache2 설정 수정

apache2 설정파일은 /etc/apache2 에 위치해 있습니다

apache2.conf가 설정파일 conf/httpd.conf 가 아님..

근데 잘 보면 기존에 사용하던

LoadModule jk_module /usr/lib/apache2/modules/mod_jk.so

문구가 없는게 모듈관리를 별도로 하나봅니다

그냥 마지막줄에 추가해도 될것 같긴합니다만... 룰에 맞춰 봅니다 세삼 한숨만..

143 IncludeOptional mods-enabled/*.conf

218 IncludeOptional conf-enabled/*.conf

이렇게 두개가 눈에 띄니 뭔지 확인해봅니다

mods-enabled를 보니 jk.conf 와 jk.load 가

conf-enabled를 보니 언어셋 등 apache 기본 설정부분이 눈에 띄네요

mods-enabled/jk.conf jk.load를 확인해봅니다

세상에 libapache2-mod-jk 설치하면서 자동으로 LoadModule 설정까지.. 되나보네요

세상 삽질한기분..

그럼 요청 Url처리를 하도록 Jkmount 를 추가해주고

workers.properties를 만들어줘야 겠네요

어디에 넣어야 하나 고민하다가 보니 sites-available / sites-enabled 가 보이네요.

어디까지 나눠놓은거지... 

 

sites-available 에 rasp2-dev.conf 파일을 하나 생성하고

VirtualHost 설정에 JkMount /* tomcat9 로 해놨습니다 

요청오면 전부 tomcat9에서 처리해라 이거죠

사실 정적파일은 apache에서 처리하도록 하는게 더 빠르니 참고하시길

주로  resource로 img, js, css 파일들

/etc/apache2/sites-available 에서 작업했습니다

그리고 기존에 설정된 000-default.conf 를 삭제하고 rasp2-dev.conf를 sites-enabled에 링크를 걸어줬습니다 그냥 sites-enabled에다 작성하고 000-default.conf를 삭제해도 됩니다

설정들이 available에 되있고 enabled에 링크걸린걸 따라한거라 전혀 상관없습니다

취향인거죠

• workers.properties 수정

workers.properties 파일은 mod_jk 가 설치된

 /etc/libapache2-mod-jk 에 위치해있습니다

뭐 mods-available/jk.conf 에서 위치를 변경해도 될것 같긴합니다만

이미 만들어져있는데 굳이 새로 만들필요가 없으니 수정합니다

라인(숫자)는 신경쓰지 마시세요 보기편하게 설정한 내용만 추렸습니다

AJP13(Apache Jserv Protocol)는 검색하시고

tomcat-hom과 java_home은 버전확인할때 본 정보로 넣어주시면됩니다

 

worker 설정을 tomcat 정보로 넣어줍니다

100, 101은 loadbalancer 기능인데 한대라서 의미없긴합니다...

적어도 2대 이상있어야...하고 주석처리되있어도 동작하는데 문제없습니다

tomcat server.xml에 이미

ajp13 포트가 8009로 설정되있고 host는 동일 서버라 localhost 입니다

여기까지 해놔도 연동에는 문제없습니다..

앞에 말한데로 로드밸런스를 하기위핸 적어도 2대는 있어야하는대

1대라서 의미가 없습니다

 

• tomcat server.xml 수정

workers.properties와 server.xml의 정보를 맞춰줘야 합니다만

이미 톰캣설정에 맞춰서 workers.properties를 만들어놔서 손을 안대도 됩니다

로드밸런스 할때만 의미있습니다

2대 이상일때는 loadbalancer로 지정한 tomcat9과 jvmRoute를 맞춰주면 됩니다

해도그만 안해도 그만...

수정했으면 tomcat, apache 순으로 재시작을 해봅니다

• 연동 확인

연동확인은 별거 없습니다

브라우져에서 http://localhost:8080 과 http://localhost 를 접속해 보면 되거든요

80포트는 기본이라서 넣어도 되고 안넣어도 됩니다 http://localhost:80

 

• http://localhost:8080

기본 8080 포트로 tomcat이 돌고 있습니다

 

• http://localhost 기존 000-defualt.conf 설정 시

apache 설정을 변경하기 전 80포트 접속화면입니다

 

• http://localhost rasp2-dev.conf 설정 시

apache + tomcat 연동이 적용된 화면입니다
