一、start.sh

cd `dirname $0`

BIN_DIR=`pwd`

cd ..

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`

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'`

三、restart.sh

#!/bin/bash

cd `dirname $0`

./stop.sh

./start.sh
