Apache Druid安装部署手册

Apache Druid安装部署手册,第1张

Apache Druid安装部署手册 一 Apache Druid架构 1. Coordinator

监控Historical处理,负责分配segments到指定的服务,确保存在HIstorical中是自平衡的

2. Overlord

监控MiddleManager处理和控制数据加载进druid集群;对分配给MiddleManager的摄取任务和协调segments的发布负责

3. Broker

处理来自客户端的查询,解析将查询重定向到Historical和MiddleManager,Broker接收到数据从这个子查询中,合并这些结果然后返回给查询者

4. Router

提供了Brokers,Overlords,Coordinator的统一路由网关

5. Historical

是一个处理存储和历史数据查询查询到工作站,Historical处理从deep storage加载过来的segments,对这些segments从broker发出的历史数据的查询做出回应

6. MiddleManager

摄取新数据到集群中;它负责度额外的数据源(新的实时的数据)和发布新的druid segments,是一个执行提交任务的工作节点;提交任务到peon上在一个独立的JVMs,因为任务的资源和日志的隔离,每一个Peon使用了隔离的JVMS,每一个Peon同时每次只能运行一个task,一个MiddleManager有多个peon

7. 额外依赖

Deep storage:一个被druid可访问的共享的文件存储;比如分布式文件系统HDFS、S3、一个网络挂在的文件系统;用它来存储已经陪摄入的任何数据;
metadata store:一个共享的元数据存储,典型的关系型数据库PostgreSql和Mysql;
Zookeeper:一个被用来了额外服务发现、协调、领导选举的;

二 准备工作 1. mysql(作为Druid的 metadata Storage)

创建数据库:

CREATE DATAbase druid DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;

授权:

grant all privileges on druid.* to druid@'%' identified by 'druid';
2. 集群节点规划 IP地址节点功能部署服务10.0.111.140Master ServerCoordinator、Overlord10.0.111.141~143Data ServerHistorical、MiddleManager10.0.111.144Query ServerBroker 、router 3. druid访问地址

Coordinator
http://10.0.111.140:8081Router
http://10.0.111.144:8888 三 集群配置 1. 下载安装包

在规划的master server节点下载安装包,并在/opt/tools目录下解压

wget https://mirrors.tuna.tsinghua.edu.cn/apache/druid/0.18.1/apache-druid-0.18.1-bin.tar.gz

以下 *** 作均需cd /opt/tools/apache-druid-0.18.1/目录下进行
注以下参数设置要求:

druid.processing.numMergeBuffers = max(2, druid.processing.numThreads / 4)
druid.processing.numThreads =  Number of cores - 1 (or 1)
druid.server.http.numThreads = max(10, (Number of cores * 17) / 16 + 2) + 30
MaxDirectMemorySize >= druid.processing.buffer.sizeByte *(druid.processing.numMergeBuffers + druid.processing.numThreads + 1) 
2. 修改common配置

common.runtime.properties配置文件
druid集群以mysql作为元数据存储、HDFS为深度存储

vim conf/druid/cluster/_common/common.runtime.properties
druid.extensions.loadList=["druid-hdfs-storage", "druid-kafka-indexing-service", "druid-datasketches","mysql-metadata-storage"]
druid.extensions.hadoopDependenciesDir=/opt/tools/druid/hadoop-dependencies
druid.host=hadoop10
druid.startup.logging.logProperties=true
druid.zk.service.host=hadoop1:2181,hadoop2:2181,hadoop3:2181,hadoop4:2181,hadoop5:2181

druid.server.hiddenProperties=["druid.s3.accessKey","druid.s3.secretKey","druid.metadata.storage.connector.password"]
druid.sql.enable=true
druid.lookup.enableLookupSynconStartup=false

拷贝hdfs相关配置文件至conf/druid/cluster/_common/目录下
修改各个节点druid.host配置

3. 同步druid目录到其他的节点上 4. 修改master节点配置

四 集群启动关闭 1. 后台启动关闭
nohup ./bin/start-cluster-master-no-zk-server start >/dev/null 2>&1 & 
nohup ./bin/start-cluster-query-server start  >/dev/null 2>&1 &
nohup ./bin/start-cluster-data-server start >/dev/null 2>&1 &
./bin/service --down
2. 服务方式启动关闭

centos 7服务启动

vim /lib/systemd/system/druidmaster.service
[Unit]
Description=druidmaster
After=network.target
[Service]
Type=forking
EnvironmentFile=/home/path
WorkingDirectory=/opt/tools/apache-druid-0.20.2/
ExecStart=/opt/tools/apache-druid-0.20.2/bin/start-cluster-master-no-zk-server start
ExecStop=/opt/tools/apache-druid-0.20.2/bin/service --down
Restart=1

[Install]
WantedBy=multi-user.target
vim /home/path
JAVA_HOME=/opt/tools/jdk
PATH=/opt/tools/jdk/bin:/opt/tools/jdk/jre/bin:/usr/local/jdk/bin:/usr/local/jdk/jre/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
source /home/path
chmod 764 /lib/systemd/system/druidmaster.service
chmod 764 /usr/lib/systemd/system/druidmaster.service
systemctl start druidmaster.service
五 遇到问题 1. hdfs深度存储没有生效

解决方法:拷贝hdfs相关配置文件至conf/druid/cluster/_common/目录下

2. 服务启动失败,运行目录下生成大量的hs_err_pid*.log日志

查看日志tailf -100 var/sv/historical.log
查看java报错日志tailf -100 hs_err_pid2416.log
解决方法:查看服务器可使用内存比角色jvm配置低,修改jvm配置文件,启动成功

3. 所有druid服务后台启动,退出xshell,druid进程被杀死

druid服务器所在机器是通过公网服务器跳转ssh登陆,当退出xshell时,无法向服务器发送正确的终止信号,nohup程序没有收到正常的退出指令
解决方法:正常exit退出xshell

4. 防止日志过爆

每个角色jvm.config添加如下配置:
-Ddruidrole=coordinator-overlord
修改log4j2.xml文件配置日志策略:


    
        var/log/druid
        ${sys:druidrole}
