Installing Apache Tomcat 6 on RHEL or CentOS
현재 CentOS의 최신 버전인 5.6도 아직까지 Tomcat 5까지만 패키지로 제공하고 있다. 하지만 문제는 이 패키지가 Oracle에서 제공하는 JDK와는 잘 맞지 않는다는데 있다.
여기서는 JDK 6 와 Tomcat 6 버전을 CentOS 5.6기반에 설치하는 것을 기술하도록 한다.
Oracle JDK 6.0 설치
Apache Tomcat 6 설치
- 압축 해제 및 소유권 할당
cd /tmp tar -zxvf apache-tomcat-6.0.32.tar.gz -C /usr/share/ ln -s /usr/share/apache-tomcat-6.0.32 /usr/share/tomcat6 useradd -u 501 -M -d /usr/share/tomcat6 tomcat chown -R tomcat: /usr/share/apache-tomcat-6.0.32 chown -h tomcat: /usr/share/tomcat6여기서 다운로드 받은 apache-tomcat 파일은 /tmp 디렉토리에 있으며, 버전은 6.0.32를 사용하는 것으로 하겠다.
