为了简化tomcat的部署复杂度, 把以前单独配置的脚本提出来做了一个带参数的, 可以用于单机环境下的多tomcat实例管理.

其中deploy功能, 会将指定的模块war按日期时间更名备份后, 再部署新的war

命令行格式为 

tc.sh [tomcat_location] {status|start|stop|restart|jstat|deploy} [module_name]

脚本代码 

# Please define the absolute path of tomcat instance

JAVA_HOME=/opt/java/jdk1..0_101

TC_BASE=/home/tomcat

BUILD_FOLDER=/home/tomcat/builds

status() {

  echo -n "[$(date +%Y%m%d-%H%M%S)] "

  pid=`ps -ef|grep ${CATALINA_BASE}|grep -v 'grep'|grep 'java'|awk '{print $2}'`

  if [ -z ${pid} ] ; then

    echo $' is not running'

  else

    echo $' is running at pid: '${pid}

  fi

}

start() {

  echo -n "[$(date +%Y%m%d-%H%M%S)] Start: "

  pid=`ps -ef|grep ${CATALINA_BASE}|grep -v 'grep'|grep 'java'|awk '{print $2}'`

  if [ -z ${pid} ] ; then

    echo $

    . ${CATALINA_BASE}/bin/startup.sh

  else

    echo $' is running at pid: '${pid}

  if [ -z $pid ] ; then

    echo $' is not running'

  else

    echo $' is running at pid:'${pid}

    . ${CATALINA_BASE}/bin/shutdown.sh

    sleep

  fi

  pid=`ps -ef|grep ${CATALINA_BASE}|grep -v 'grep'|grep 'java'|awk '{print $2}'`

  if [ -z $pid ] ; then

    ps -ef|grep ${CATALINA_BASE}|grep -v 'grep'|grep 'java'|awk '{print $2}'|xargs kill -s

  cp -f ${BUILD_FOLDER}/$.war ${CATALINA_BASE}/webapps/

  echo 'done'

  start $

}

jstat() {

  pid=`ps -ef|grep ${CATALINA_BASE}|grep -v 'grep'|grep 'java'|awk '{print $2}'`

  fi

}

if [ -z $ ]; then

  echo $"Usage: $0 [tomcat_location] {status|start|stop|restart|jstat|deploy} [module_name]"

  exit

else

  target=${%/}

fi

CATALINA_BASE=${TC_BASE}/$target

[ -d ${CATALINA_BASE} ] || exit 

case "$2" in

    status)

        $ $target

        ;;

    start)

        $ $target

        ;;

    stop)

        $ $target

        ;;

    restart)

        $ $target

        ;;

    jstat)

        $ $target

        ;;

    deploy)

        $ $target $

        ;;

    *)

        echo $"Usage: $0 [tomcat_location] {status|start|stop|restart|jstat|deploy} [module_name]"

        exit

esac

对应的tomcat实例内部的startup.sh 和 shutdown.sh, 只需要配置jvm参数和tomcat源路径

startup.sh 

JAVA_OPTS="-server -Xms1024m -Xmx1024m -XX:MaxNewSize=512m -Djava.awt.headless=true"

CATALINA_HOME=/opt/tomcat/apache-tomcat-8.0.

. $CATALINA_HOME/bin/catalina.sh start

shutdown.sh 

CATALINA_HOME=/opt/tomcat/apache-tomcat-8.0.

. $CATALINA_HOME/bin/catalina.sh stop
