linux下啟動java程序的通用腳本介紹

  一、start.sh

  #!/bin/bash

  cd `dirname $0`

  BIN_DIR=`pwd`

  cd ..

  DEPLOY_DIR=`pwd`

  CONF_DIR=$DEPLOY_DIR/conf

  SERVER_NAME=`sed '/server.name/!d;s/.*=//' conf/server.properties | tr -d '\r'`

  fi

  PIDS=`ps --no-heading -C java -f --width 1000 | grep "$CONF_DIR" |awk '{print $2}'`

  if [ -n "$PIDS" ]; then

  echo "ERROR: The $SERVER_NAME already started!"

  echo "PID: $PIDS"

  exit 1

  fi

  echo -e "Starting the $SERVER_NAME ...\c"

  nohup java $JAVA_OPTS $JAVA_MEM_OPTS $JAVA_DEBUG_OPTS $JAVA_JMX_OPTS -classpath $CONF_DIR:$LIB_JARS com.hzins.framework.server.ServerMain > $STDOUT_FILE 2>&1 &

  COUNT=0

  while [ $COUNT -lt 1 ]; do

  echo -e ".\c"

  sleep 1

  # if [ -n "$SERVER_PORT" ]; then

  # COUNT=`echo status | nc 127.0.0.1 $SERVER_PORT -i 1 | grep -c OK`

  PIDS=`ps --no-heading -C java -f --width 1000 | grep "$DEPLOY_DIR" | awk '{print $2}'`

  echo "PID: $PIDS"

  二、stop.sh

  #!/bin/bash

  cd `dirname $0`

  BIN_DIR=`pwd`

  cd ..

  DEPLOY_DIR=`pwd`

  break

  fi

  done

  done

  echo "OK!"

  echo "PID: $PIDS"

  三、restart.sh

  #!/bin/bash

  cd `dirname $0`

  ./stop.sh

  ./start.sh
