StarRocks官方文档： StarRocks | StarRocks

StarRocks下载地址： Download StarRocks Free | StarRocks 选择自己要安装的版本下载,StarRocks-3.2.1.tar.gz

wget https://releases.starrocks.io/starrocks/StarRocks-3.2.1.tar.gz

准备StarRocks部署脚本

修改StarRocks的JAVA环境

• 由于StarRocks最新版FE本需要jdk11及以上的版本，而大数据平台默认安装jdk1.8，需要添加额外的jdk版本和启动参数

下载jdk11及以上的版本放到服务器：/opt/jdk-11.0.0.1

解压安装包

tar -zxvf StarRocks-3.2.1.tar.gz

修改fe的环境变量脚本 fe/bin/common.sh

在jdk_version最前面设置JAVA_HOME

jdk_version() {
    JAVA_HOME=/opt/jdk-11.0.0.1 # 添加 JAVA_HOME
    local result
    local java_cmd=$JAVA_HOME/bin/java
    local IFS=$'\n'
    # remove \r for Cygwin
    ...........
}

修改 启动脚本fe/bin/start_fe.sh

JAVA_HOME=/opt/jdk-11.0.0.1  # 添加 JAVA_HOME
# java
if [[ -z ${JAVA_HOME} ]]; then
    if command -v javac &> /dev/null; then
        export JAVA_HOME="$(dirname $(dirname $(readlink -f $(which javac))))"
        echo "Infered JAVA_HOME=$JAVA_HOME"
    else
      cat <<
      ..................

新增检查fe状态脚本 fe/bin/status_fe.sh。使用方式： ./status_fe.sh status

#!/bin/bash
usage="Usage: start.sh (status) <command> "
 
# if no args specified, show usage
if [ $# -lt 1 ]; then
  echo $usage
  exit 1
fi
startStop=$1
shift
 
SH_DIR=`dirname $0`
echo $SH_DIR
export PID_DIR=$SH_DIR
pid=$PID_DIR/fe.pid
 
status(){
  if [ -f $pid ]; then
    ARGET_PID=`cat $pid`
    kill -0 $ARGET_PID
    if [ $? -eq 0 ]
    then
      echo "SR fe pid $ARGET_PID $startStop is  running "
    else
      echo "SR fe pid $ARGET_PID $startStop  is not running"
      exit 1
    fi
  else
    echo "SR fe pid $ARGET_PID $startStop  pid file is not exists"
    exit 1
        fi
}
 
case $startStop in
 
  (status)
          status
        ;;
  (*)
    echo $usage
    exit 1
    ;;
esac
 
echo "End $startStop $command."
 

新增检查be状态脚本 be/bin/status_be.sh。使用方式： ./status_be.sh status

#!/bin/bash
usage="Usage: start.sh (status) <command> "
 
# if no args specified, show usage
if [ $# -lt 1 ]; then
  echo $usage
  exit 1
fi
startStop=$1
shift
 
SH_DIR=`dirname $0`
echo $SH_DIR
export PID_DIR=$SH_DIR
pid=$PID_DIR/be.pid
 
status(){
  if [ -f $pid ]; then
    ARGET_PID=`cat $pid`
    kill -0 $ARGET_PID
    if [ $? -eq 0 ]
    then
      echo "SR be pid $ARGET_PID $startStop is  running "
    else
      echo "SR be pid $ARGET_PID $startStop  is not running"
      exit 1
    fi
  else
    echo "SR be pid $ARGET_PID $startStop  pid file is not exists"
    exit 1
        fi
}
 
case $startStop in
 
  (status)
          status
        ;;
  (*)
    echo $usage
    exit 1
    ;;
esac
 
echo "End $startStop $command."
 

重新打包压缩部署文件，并生成MD5,MD5在部署的时候需要使用

tar -czvf StarRocks-3.2.1.tar.gz StarRocks-3.2.1
md5sum  StarRocks-3.2.1.tar.gz
56470a0a0d4aac2c8dcf3d85187aede1  StarRocks-3.2.1.tar.gz
echo 56470a0a0d4aac2c8dcf3d85187aede1 > StarRocks-3.2.1.tar.gz.md5

准备服务配置模板

服务配置模板在datasophon-worker里面，需要添加文件fe.ftl和be.ftl重新打包（原生有fe.ftl,需要修改），并重新安装

或者直接在每个节点的datasophon-worker配置目录下添加配置模板

模板路径： ./conf/templates

[root@datasophon-test templates]# pwd
/opt/datasophon/datasophon-worker/conf/templates
[root@datasophon-test templates]# ls
alertmanager.yml          doris_fe.ftl        jaas.ftl             kafka-server-start.ftl  properties3.ftl     scrape.ftl             xml.ftl
alert.yml                 fair-scheduler.ftl  jvm.config.ftl       kdc.ftl                 properties.ftl      singleValue.ftl        zk-env.ftl
be.ftl                    fe.ftl              jvm.options.ftl      krb5.ftl                ranger-hbase.ftl    spark-env.ftl          zk-jaas.ftl
capacity-scheduler.ftl    hadoop-env.ftl      kadm5.ftl            kyuubi-env.ftl          ranger-hdfs.ftl     starrocks-prom.ftl
dinky.ftl                 hbase-env.ftl       kafka-jaas.ftl       prometheus.ftl          ranger-hive.ftl     streampark.ftl
dolphinscheduler_env.ftl  hive-env.ftl    

fe.ftl 内容：

注意： 模板中如有变量需要调整，例如：${STARROCKS_HOME}/log需要写为：${r"${STARROCKS_HOME}/log"}，否则安装过程会报错

分发模板到所有work节点的模板下：

scp -r {fe.ftl,be.ftl} root@192.168.1.225:/opt/datasophon/datasophon-worker/conf/templates
 
scp -r {fe.ftl,be.ftl} root@192.168.1.226:/opt/datasophon/datasophon-worker/conf/templates

重启所有work节点

sh /opt/datasophon/datasophon-worker/bin/datasophon-worker.sh restart worker

准备StarRocks部署配置文件service_ddl.json

• 创建自定义服务目录，必须大写

cd  /opt/datasophon/datasophon-manager-1.2.1/conf/meta/DDP-1.2.1/
mkdir STARROCKS
touch service_ddl.json

service_ddl.json文件内容：

重启datasophon-manager的api

cd  /opt/datasophon/datasophon-manager-1.2.1
./bin/datasophon-api.sh restart api

安装StarRocks

安装fe

安装be

检查参数具体配置，如需修改可在此处修改

注意：请修改参数priority_networks为服务器使用的内网网络 例如：192.168.1.0/24，设置为0.0.0.0/24 be无法注册到集群

等待安装完成

StarRocks集成grafana监控

StarRocks社区推荐的开源监控方案是Prometheus+Grafana。StarRocks提供了兼容Prometheus的信息采集接口，Prometheus可以通过连接BE/FE的HTTP端口来获取集群监控指标的metric信息，存储在自身的时序数据库中。Grafana则可以将Prometheus作为数据源来进行图形化展现。搭配StarRocks提供的Dashboard模板，开发者能够便捷的实现StarRocks集群监控指标的统计展示和阈值告警。

StarRocks社区仅提供基于Prometheus和Grafana实现的一种StarRocks可视化监控方案，原则上不维护和开发这些组件，更多详细的关于Prometheus和Grafana的介绍和使用，请参考对应的官方文档。

【最全指南】StarRocks Prometheus+Grafana 监控报警配置 - 🙌 StarRocks 技术分享 - StarRocks中文社区论坛 (mirrorship.cn)

Prometheus 配置

找到Prometheus部署服务器

添加starrock配置 vim prometheus.yml,新增如下内容

  - job_name: 'StarRocks'
    metrics_path: '/metrics'
    file_sd_configs:
     - files:
       - configs/starrocks.json

vim configs/starrocks.json 端口为fe和be的http端口

[
  {
    "targets":["192.168.1.224:8060","192.168.1.225:8060","192.168.1.226:8060"],
    "labels":
    {
       "group": "fe"
    }
  },
  {
    "targets":["192.168.1.224:8070","192.168.1.225:8070","192.168.1.226:8070"],
    "labels":
    {
       "group": "be"
    }
  }
]
 
 

然后重启Prometheus服务

Grafana 配置

通过下图展示的url进去grafana配置图表，默认登陆账户密码：admin ：admin

1）下载模板：

StarRocks 2.5版本监控模版的下载地址为：

https://starrocks-thirdparty.oss-cn-zhangjiakou.aliyuncs.com/StarRocks-Overview-2.5.json 21

浏览器打开下载地址，右键，另存为，在桌面保存即可。这里注意，我们需要将json文件下载到“浏览器所在的机器上”，因为json模板是需要通过浏览器上传的，所以这里不要下载到Linux服务器上，而是需要下载到咱们打开Web所用的机器上。

2）配置模板：

点击目录-->Dashboards-->New右侧的展开符号-->Import-->Upload dashboard JSON file，将下载的json文件导入。导入后，可以命名Dashboard，默认是StarRocks Overview。同时，需要选择数据源，这里选择默认数据源Prometheus。点击Import，即完成导入。之后，可以看到StarRocks的Dashboard展示：

配置DataSophon 引用自定义模板

找到datasophon数据库中表：t_ddh_cluster_service_dashboard

将原连接d后面的部分替换下图中自定义dashboard的url

最后的结果为：

回到datasophon的starrocks服务，刷新即可在总览看到详细监控信息
