Dolphinscheduler安装部署

官方安装指导：https://dolphinscheduler.apache.org/zh-cn/docs/1.3.4/user_doc/quick-start.html

1节点规划

机器	服务	端口	group
hadoop01	master、api、logger	8787(master)、8888(api)
hadoop02	master、alert、worker、logger	8787(master)、7878(worker)	hadoop
hadoop03	worker、logger	7878(worker)	hadoop

hadoop 组配置后master分发任务才能根据cpu和内存的负载选择具体哪个worker执行任务

2 准备工作

1、创建目录

• 确保三个节点都有目录/bigdata/soft、/bigdata/install，且所属用户及用户组如下

[hadoop@hadoop01 ~]$ ll /bigdata/ 
总用量 0
drwxr-xr-x. 2 hadoop hadoop 6 4月  13 14:21 install 
drwxr-xr-x. 2 hadoop hadoop 6 4月  13 14:22 soft

• 若没有这些目录，那么如下创建；3个节点都运行如下命令

sudo mkdir -p /bigdata/install  
sudo mkdir -p /bigdata/soft 
sudo chown -R hadoop:hadoop /bigdata/   
ll /bigdata/

2、确保已安装zookeeper集群

• 启动zookeeper集群
• 确保三节点上已经安装了zk
• zk版本要求：ZooKeeper (3.4.6+)
• 若没有安装，请先安装再往下继续

3、启动HDFS

• 因为ds的资源存储在HDFS上
• 所以，hadoop01上运行start-dfs.sh启动hdfs

3 开始安装

第一步：安装包下载，在hadoop01上执行

[hadoop@hadoop01~]$ cd /bigdata/soft/
[hadoop@hadoop01 soft]$ wget https://mirrors.tuna.tsinghua.edu.cn/apache/incubator/dolphinscheduler/1.3.5/apache-dolphinscheduler-incubating-1.3.5-dolphinscheduler-bin.tar.gz

第二步：解压压缩包

[hadoop@hadoop01 soft]$ tar -xzvf apache-dolphinscheduler-incubating-1.3.5-dolphinscheduler-bin.tar.gz -C /bigdata/install/   

第三步：重命名

[hadoop@hadoop01 soft]$ cd /bigdata/install/  
[hadoop@hadoop01 install]$ mv apache-dolphinscheduler-incubating-1.3.5-dolphinscheduler-bin/ dolphinscheduler-1.3.5   
[hadoop@hadoop01 install]$ ll 
总用量 0
drwxrwxr-x. 9 hadoop hadoop 156 4月  13 14:35 dolphinscheduler-1.3.5

第四步：建库建表

此处以hadoop03安装了mysql为例
hadoop01上

[hadoop@hadoop01 install]$ scp /bigdata/install/dolphinscheduler-1.3.5/sql/dolphinscheduler_mysql.sql hadoop03:/bigdata/soft/   

hadoop03上，进入MySQL命令行执行

mysql -uroot -p 

set global validate_password_policy=LOW;
set global validate_password_length=6;  
CREATE DATABASE IF NOT EXISTS dolphinscheduler DEFAULT CHARSET utf8 DEFAULT COLLATE utf8_general_ci;
GRANT ALL PRIVILEGES ON dolphinscheduler.* TO 'root'@'%' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON dolphinscheduler.* TO 'root'@'localhost' IDENTIFIED BY '123456';
flush privileges;   
use dolphinscheduler;   
source /kkb/soft/dolphinscheduler_mysql.sql;
mysql> show tables;

第五步：修改配置文件

[hadoop@hadoop01 ~]$ cd /bigdata/install/dolphinscheduler-1.3.5/conf/ 

1、alert.properties

配置告警邮箱相关信息

• 此处已126邮箱为例
• 登录自己的126邮箱
  

• 开始配置文件

[hadoop@hadoop01 conf]$ vim alert.properties  
#alert type is EMAIL/SMS
alert.type=EMAIL

# mail server configuration 
mail.protocol=SMTP  
mail.server.host=smtp.126.com   
mail.server.port=25 
mail.sender=youhy964@126.com
mail.user=youhy964@126.com  
mail.passwd=WBNPUGCNZMQQYBUT
# TLS   
mail.smtp.starttls.enable=true  
# SSL   
mail.smtp.ssl.enable=false  
mail.smtp.ssl.trust=smtp.126.com

2、application-api.properties

• 修改web ui端口号

[hadoop@hadoop01 conf]$ vim application-api.properties

# server port   
server.port=8888

3、common.properties

# 修改如下3个属性的值   
[hadoop@hadoop01 conf]$ vim common.properties 

resource.storage.type=HDFS  
fs.defaultFS=hdfs://hadoop01:8020 
yarn.application.status.address=http://hadoop01:8088/ws/v1/cluster/apps/%s

4、datasource.properties

假设mysql安装在hadoop03节点

# 修改如下几个属性的值
[hadoop@hadoop01 conf]$ vim datasource.properties 

spring.datasource.driver-class-name=com.mysql.jdbc.Driver   
spring.datasource.url=jdbc:mysql://hadoop03:3306/dolphinscheduler?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true  
spring.datasource.username=root 
spring.datasource.password=123456   

5、master.properties

[hadoop@hadoop01 conf]$ vim master.properties 

master.listen.port=8787 

6、worker.properties

[hadoop@hadoop01 conf]$ vim worker.properties 

worker.listen.port=7878 
worker.groups=hadoop

7、zookeeper.properties

[hadoop@hadoop01 conf]$ vim zookeeper.properties  

zookeeper.quorum=hadoop01:2181,hadoop02:2181,hadoop03:2181

8、env/dolphinscheduler_env.sh

# 修改如下属性，根据自己的实际情况，配置属性值 |
[hadoop@hadoop01 conf]$ vim env/dolphinscheduler_env.sh   

export HADOOP_HOME=/bigdata/install/hadoop-3.1.4
export HADOOP_CONF_DIR=/bigdata/install/hadoop-3.1.4/etc/hadoop 
export SPARK_HOME1=/bigdata/install/spark-2.3.3-bin-hadoop2.7   
export JAVA_HOME=/bigdata/install/jdk1.8.0_141  
export HIVE_HOME=/bigdata/install/hive-3.1.2 

第六步：将hdfs-site.xml、core-site.xml 拷贝至ds的 conf 目录下，同时 把mysql-connector-java-5.1.48-bin.jar驱动包上传到ds的lib目录下

[hadoop@hadoop01 conf]$ cp /bigdata/install/hadoop-3.1.4/etc/hadoop/hdfs-site.xml /bigdata/install/dolphinscheduler-1.3.5/conf
[hadoop@hadoop01 conf]$ cp /bigdata/install/hadoop-3.1.4/etc/hadoop/core-site.xml /bigdata/install/dolphinscheduler-1.3.5/conf

# 将mysql-connector-java-5.1.38.jar上传到hadoop01的/bigdata/soft目录  
[hadoop@hadoop01 soft]$ cd /bigdata/soft/ 
[hadoop@hadoop01 soft]$ cp mysql-connector-java-5.1.38.jar /bigdata/install/dolphinscheduler-1.3.5/lib/   

第七步：到ds的bin目录下（1.3.5版本，可以跳过此步）

dos2unix dolphinscheduler-daemon.sh   #dos2unix:将DOS格式的文本文件转换成UNIX格式的(DOS/MAC to UNIX text file format converter)
chmod +x dolphinscheduler-daemon.sh 

第八步：scp到hadoop02、hadoop03

[hadoop@hadoop01 bin]$ cd /bigdata/install/   
[hadoop@hadoop01 install]$ scp -r dolphinscheduler-1.3.5/ hadoop02:$PWD 
[hadoop@hadoop01 install]$ scp -r dolphinscheduler-1.3.5/ hadoop03:$PWD 

4 调优配置

生产环境上建议，worker.properties里设置的cpu和内存调一下就可以保护worker不至于挂掉，一般别超过cpu核数的2倍，内存留上1~2G（当然如果比较豪，可以预留更多资源），线程数别超过cp倍。

例如：8c16G机器 worker.exec.threads=20  worker.max.cpuload.avg=16   worker.reserved.memory=1

同理对于master调优配置 8c16G机器   master.properties文件  master.max.cpuload.avg=16  master.reserved.memory=1

5 启动

在hadoop01 启动 master、api、logger

[hadoop@hadoop01 ~]$ cd /bigdata/install/dolphinscheduler-1.3.5/bin/  
[hadoop@hadoop01 bin]$ ./dolphinscheduler-daemon.sh start master-server   
[hadoop@hadoop01 bin]$ ./dolphinscheduler-daemon.sh start api-server  
[hadoop@hadoop01 bin]$ ./dolphinscheduler-daemon.sh start logger-server   

在hadoop02 启动 master、alert、worker、logger

[hadoop@hadoop02 ~]$ cd /bigdata/install/dolphinscheduler-1.3.5/bin/  
[hadoop@hadoop02 bin]$ ./dolphinscheduler-daemon.sh start master-server   
[hadoop@hadoop02 bin]$ ./dolphinscheduler-daemon.sh start alert-server
[hadoop@hadoop02 bin]$ ./dolphinscheduler-daemon.sh start worker-server   
[hadoop@hadoop02 bin]$ ./dolphinscheduler-daemon.sh start logger-server   

在hadoop03 启动 worker、logger

[hadoop@hadoop03 ~]$ cd /bigdata/install/dolphinscheduler-1.3.5/bin/  
[hadoop@hadoop03 bin]$ ./dolphinscheduler-daemon.sh start worker-server   
[hadoop@hadoop03 bin]$ ./dolphinscheduler-daemon.sh start logger-server   

目前3节点已经启动了hadoop集群、zookeeper集群、及ds相关进程；
启动成功之后，会出现如下进程

[hadoop@hadoop01 bin]$ xcall jps  
============= hadoop01 jps =============  
3680 ApiApplicationServer   
2465 DataNode   
3761 LoggerServer   
3410 JobHistoryServer   
2036 QuorumPeerMain 
2294 NameNode   
3607 MasterServer   
2666 SecondaryNameNode  
2892 ResourceManager
3037 NodeManager
4351 Jps
============= hadoop02 jps =============  
2320 NodeManager
2880 LoggerServer   
2179 DataNode   
3446 Jps
3287 AlertServer
2616 MasterServer   
2798 WorkerServer   
2031 QuorumPeerMain 
============= hadoop03 jps =============  
2160 DataNode   
2289 NodeManager
3009 LoggerServer   
1996 QuorumPeerMain 
2927 WorkerServer   
3103 Jps

• 如何关闭ds集群？
• 关闭个节点的各角色，就是将上边启动命令中的start换成stop即可

[hadoop@hadoop01 ~]$ cd /bigdata/install/dolphinscheduler-1.3.5/bin/  
[hadoop@hadoop01 bin]$ ./dolphinscheduler-daemon.sh stop master-server
[hadoop@hadoop01 bin]$ ./dolphinscheduler-daemon.sh stop api-server   
[hadoop@hadoop01 bin]$ ./dolphinscheduler-daemon.sh stop logger-server

[hadoop@hadoop02 ~]$ cd /bigdata/install/dolphinscheduler-1.3.5/bin/  
[hadoop@hadoop02 bin]$ ./dolphinscheduler-daemon.sh stop master-server
[hadoop@hadoop02 bin]$ ./dolphinscheduler-daemon.sh stop alert-server 
[hadoop@hadoop02 bin]$ ./dolphinscheduler-daemon.sh stop worker-server
[hadoop@hadoop02 bin]$ ./dolphinscheduler-daemon.sh stop logger-server

[hadoop@hadoop03 ~]$ cd /bigdata/install/dolphinscheduler-1.3.5/bin/  
[hadoop@hadoop03 bin]$ ./dolphinscheduler-daemon.sh stop worker-server
[hadoop@hadoop03 bin]$ ./dolphinscheduler-daemon.sh stop logger-server
