一、start.sh

#!/bin/bash

cd `dirname $0`
BIN_DIR=`pwd`
cd ..
DEPLOY_DIR=`pwd`

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

exit 1
fi
fi


LOGS_DIR=""
LOGS_DIR=$DEPLOY_DIR/logs


#if [ ! -d $LOGS_DIR ]; then

if [ -n "$BITS" ]; then
let memTotal=`cat /proc/meminfo |grep MemTotal|awk '{printf "%d", $2/1024 }'`
if [ $memTotal -gt 2500 ];then

else

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 $SERVER_PORT -i 1 | grep -c OK`
# else
COUNT=`ps --no-heading -C java -f --width 1000 | grep "$DEPLOY_DIR" | awk '{print $2}' | wc -l`

fi
done

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

二、stop.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'`


if [ -z "$SERVER_NAME" ]; then
SERVER_NAME=`hostname`
fi


PIDS=`ps --no-heading -C java -f --width 1000 | grep "$CONF_DIR" |awk '{print $2}'`
if [ -z "$PIDS" ]; then
echo "ERROR: The $SERVER_NAME does not started!"
exit 1
fi


if [ "$1" != "skip" ]; then
$BIN_DIR/dump.sh
fi


echo -e "Stopping the $SERVER_NAME ...\c"
for PID in $PIDS ; do
kill $PID > /dev/null 2>&1
done


COUNT=0
while [ $COUNT -lt 1 ]; do
echo -e ".\c"
sleep 1
COUNT=1

COUNT=0
break
