톰캣 멀티 인스턴스 구성

 

 

엔진 : /sw/tomcat11

디렉토리를 지운 것은 아니지만, 엔진 단에는 lib와 bin 경로만 있으면 된다.

 

 

인스턴스 : /sw/kb11 & /sw/kb12

엔진 단에 있는 temp, webapps, work, logs, conf를 복사해 온다.

※ 참고로 여기에 있는 bin 경로는 인스턴스 기동을 위한 sh 파일만 있다.

 

 

start.sh

#!/bin/sh
. ./setenv.sh
# Check User Name
export IAM=`id -un`
# Check Startup User Check
if [ $USER != $IAM ] ; then
  echo "Error : This user is "$IAM". Please login as a "$USER" user."
  exit
fi

# Check Process Check
export PID=`ps -ef | grep java | grep ${SERVER_NAME} | awk '{print $2}'`
if [ "$PID" != "" ] ; then
  echo "ERROR : \"${SERVER_NAME}\" server is already running!!"
  exit
fi

사실 자바옵션으로 thread 설정과 port 설정이 가능해보이지만,

${instance}/conf/server.xml을 수정해야 한다.
