1.基于https://github.com/Qihoo360/pika/的v3.1.1版本，定制出适合业务要求的功能改进版。
https://github.com/kxtry/pika是在v3.2.7基础上，新增了incrbyrange(key,val,min, max)及hincrbyrange(key,val,min, max)这两个命令。
2.官方提供的编译是直接基于docker的编译。

编译Dockerfile文件。
应该修改Dockerfile的Centos版本为FROM centos:7.5.1804
docker build -t pika .

3.提取编译后结果，也可以直接用该容器运行应用

运行应用：
docker run pika:latest bash -c "./bin/pika -c ./conf/pika.conf"
也可提取相关应用至宿主机运行。
docker cp 容器名：/pika/output ./  #docker cp ce4541cc4627:/pika/output ./

4.提取出来的应用，在宿主机上运行，需要安装相关依赖。

安装epel源。
rpm -ivh https://mirrors.ustc.edu.cn/epel/epel-release-latest-7.noarch.rpm
安装glog和protobuf的动态连接库。
sudo yum install -y glog protobuf  #编译时，对应的是glog-devel 和protobuf-devel
如果仍然无法运行，则执行strace ./pika或ldd pika来检查缺少哪些动态库。

5. 运行：

docker run pika:latest bash -c "./bin/pika -c ./conf/pika.conf"

6. 运行脚本run-app.sh

#!/bin/sh

# crontab -e
# */1 * * * * sh /data/scripts/run-app.sh start

path_current=`pwd`
path_script=$(cd "$(dirname "$0")"; pwd)

app_process=`ps -ef | grep "$name"| grep -v grep`

if [ ! -d $path_data ];then 
   mkdir -p $path_data
fi

echo `date` >> $logfile
echo "ready to check...." >> $logfile
case "$mode" in
   'install')
      if [ ! -f $path_script/.envok ]; then
         rpm -ivh https://mirrors.ustc.edu.cn/epel/epel-release-latest-7.noarch.rpm
         yum install -y glog protobuf && touch $path_script/.envok
      fi
      if [ ! -f $path_script/conf/pika.conf ]; then
         mkdir -p $path_data && /bin/cp -rf $path_script/pika.conf.template $path_script/conf/pika.conf && echo "$path_script/conf/pika.conf" | xargs /bin/sed -i "s#{{path_current}}#$path_data#g"
      fi
      ;;
   'start')
      echo "$app_process" >> $logfile
      echo "it's ready to start op...."
      if test -n "$app_process"; then
         echo ""
         echo "$app_process"
         echo ""
      else
         cd $path_script  
         nohup $path_script/bin/$name -c $path_script/conf/${name}.conf > $path_data/info.txt 2>&1 &
         echo "success to restart $name" >> $logfile
         cd $path_current
      fi
      echo 'success to start.'
      ;;
   'stop')
      echo "it's ready to check process..."
      if test -n "$app_process"; then
         echo "had find app process informaton"
         echo $app_process | awk '{print ($2)}' | xargs kill -3
      fi
      echo 'success to kill.'
      ;;
   *)
      basename=`basename "$0"`
      echo "Usage: $basename  {install|start|stop}  [ server options ]"
      exit 1
      ;;

exit 1
