操作步骤说明：

1. 安装带cm的数据库集群，配置资源脚本和自定义资源文件，资源脚本示例如下：
   cmrestapi.sh

   #!/bin/bash #set -ex #资源名称 resName=CM-RestAPI #资源binpath cmrestapiPath=/home/cmrestapi/cmrestapi-3.1.0-RELEASE.jar #资源启动命令关键词 cmdKey=cmrestapi-3.1.0-RELEASE.jar #用于保存首次检测到资源假死时间的文件 phony_dead_time_file=.cmrestapi_phony_dead_time #最长假死时间，单位为s PHONY_MAX_TIME=20 envFile=/home/cmrestapi/envfile #appWhiteListFile=/home/cmrestapi/appWhiteListFile source $envFile

   function exec_start { nohup java -jar -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=56m -Xms128m -Xmx128m -Xmn32m -Xss328k -XX:SurvivorRatio=8 -XX:+UseConcMarkSweepGC -Dserver.port=8080 $cmrestapiPath -e$envFile >> GAUSSLOG/cm/cmrestapi/cmrestapi.log 2>&1 & exit ? }

   function exec_stop { ps x | grep "cmdKey" | grep -v grep | awk '{print 1}' | xargs kill -9; exit $? }

   function exec_check { pid=ps x | grep "$cmdKey" | grep -v grep | awk '{print $1}' if [ "${pid}" == "" ]; then echo "$resName is not running." exit 1 fi state=cat /proc/$pid/status | grep "State" | awk '{print $2}' if [ "$state" == "T" ]; then if [ ! -f$phony_dead_time_file ]; then touch ./${phony_dead_time_file} echo "export firstphonytime=''" > ./${phony_dead_time_file} fi source ./$phony_dead_time_file; curtime=$(date +%s); if [ "$firstphonytime" == "" ]; then echo "export firstphonytime=$curtime" > ./$phony_dead_time_file; exit 0; fi dead_time=$(( $curtime -$firstphonytime )); if [ $dead_time -ge$PHONY_MAX_TIME ]; then echo "$resName is detected in a state of phony dead(T) and will be forcibly killed!" kill -9$pid rm ./${phony_dead_time_file} -f exec_start else exit 0 fi elif [ "$state" == "S" ]; then rm ./${phony_dead_time_file} -f echo "$resName is running normally." exit 0 fi }

   if [ $1 == '-start' ]; then exec_start$2 elif [ $1 == '-stop' ]; then exec_stop$2 elif [ $1 == '-check' ]; then exec_check$2 elif [ $1 == '-clean' ]; then exec_stop$2 elif [ $1 == '-reg' ]; then exit 0 elif [$1 == '-unreg' ]; then exit 0 elif [ $1 == '-isreg' ]; then exit 11 else echo "Please confirm the input parameters." exit 1 fi
