Apache 웹 서버와 Tomcat 애플리케이션 서버를 다중 인스턴스로 실행하는 방법

Apache의 APR 라이브러리, Tomcat 커넥터, 그리고 JDK를 사용합니다.

JDK 설치(java 설치)

tar xvfz jdk-7u65-linux-x64.tar.gz -C /app/
ln -s /app/jdk1.7.0_65 /app/java

APR 및 APR-Util 컴파일 및 설치

  • apr-1.5.1 컴파일 및 설치
tar xvfz apr-1.5.1.tar.gz
./configure --prefix=/usr/local/apr
make && sudo make install
  • apr-util-1.5.4 컴파일 및 설치
tar xvfz apr-util-1.5.4.tar.gz
./configure --with-apr=/usr/local/apr
make && sudo make install

Apache HTTP Server 컴파일 및 설치

tar xvfz httpd-2.4.9.tar.gz
./configure --prefix=/app/apache2 --with-mpm=worker --enable-mods-shared=all --enable-module=so --enable-module=rewrite --with-apr=/usr/local/apr
make && sudo make install

Tomcat Native 컴파일 및 설치

tar xvfz tomcat-native-1.1.31-src.tar.gz
cd tomcat-native-1.1.31-src/jni/native/
./configure --prefix=/app/tomcat/instance1 --with-apr=/usr/local/apr --with-java-home=/app/java --with-ssl
make && sudo make install

Tomcat Connector 컴파일 및 설치

tar xvfz tomcat-connectors-1.2.40-src.tar.gz
cd tomcat-connectors-1.2.40-src/native
./buildconf.sh
./configure --prefix=/app/apache2 --with-apxs=/app/apache2/bin/apxs
make && sudo make install

Tomcat 설정

tar xvfz apache-tomcat-7.0.56.tar.gz -C /app/tomcat/instance1

tuser 계정 생성

useradd tuser
passwd tuser
vim /home/tuser/.bash_profile
...
export JAVA_HOME="/app/java"
export PATH=$JAVA_HOME/bin/:$PATH
export TERM=xterm
export CLASSPATH=$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar
