Tomcat Apache 연동 (mod_jk)

mod_jk 란?

 

: 아파치, 톰캣 연동을 위해 mod_jk라는 모듈을 사용하는데,

이는 AJP프로토콜을 사용하여 톰캣과 연동하기 위해 만들어진 모듈이다.
mod_jk는 톰캣의 일부로 배포되지만, 아파치 웹서버에 설치하여야 한다.

 

1)tomcat-connectors-x.x.x.tar.gz을 원하는 위치로 ftp 전송 및 압축 해제 후, 해당 경로로 이동
$ tar -zxvf apr-1.x.x.tar.gz
$ cd tomcat-connectors-1.2.48-src/native

[apache@Test1 install]$ tar -zxvf tomcat-connectors-1.2.48-src.tar.gz

[apache@Test1 install]$ cd tomcat-connectors-1.2.48-src/native

2) configure, make, make install 명령어로 컴파일한다. 
$ ./configure --with-apxs=${APACHE_INSTALL_DIR}/bin/apxs 
$ make $ make install 

[apache@Test1 native]$ ./configure --with-apxs=/sw/apache/bin/apxs

3) 생성된 mod_jk.so 파일 확인 
$ ls {APACHE_INSTALL_DIR/modules/mod_jk.so

[apache@Test1 modules]$ pwd
/sw/apache/modules
[apache@Test1 modules]$ ls mod_jk.so
mod_jk.so

4) mod_jk 모듈과 톰캣을 연결하는 workers.properties 설정파일을 생성한다.
$ cd {APACHE_INSTALL_DIR}/conf 
$ vi workers.properties

[apache@Test1 conf]$ pwd
/sw/apache/conf

[apache@Test1 conf]$ vi workers.properties
worker.list=worker1
worker.worker1.port=8009
worker.worker1.host=192.168.56.251
worker.worker1.type=ajp13

5) {APACHE_INSTALL_DIR}/conf/mod_jk.conf 파일에서 JKWorkersFile 에 이전에 설정해 놓은
  mod_jk.conf 파일 내부의  workers.properties경로를 설정하여 workers.properties를 읽어온다.
$ cd {APACHE_INSTALL_DIR}/conf 
$ vi mod_jk.conf

[apache@Test1 conf]$ pwd
/sw/apache/conf
[apache@Test1 conf]$ vi mod_jk.conf 
<IfModule mod_jk.c>
 JKWorkersFile "/sw/apache/conf/workers.properties"
</IfModule>

 

6) server.xml하단에 플러그인 옵션을 작성한다. 
AJP 1.3 Connector의 주석을 해제하고 address 값을 수정한다.
$ cd ${TOMCAT_INSTALL_DIR}/conf 
$ vi server.xml

…skip…
<Connector protocol="AJP/1.3"
  address="192.168.56.251" 
  port="8009"

7) httpd.conf 하단에 해당 URI 확장자로 들어오는 Request는 workers.properties의 worker1 워커가 처리하도록 플러그인 옵션을 작성

$ vi {APACHE_INSTALL_DIR} httpd.conf

 

…skip…
Include conf/mod_jk.conf
LoadModule jk_module modules/mod_jk.so

<IfModule mod_jk.c>
