0、大前提

• 1、确保：集群机器之间 免密互信

• 2、确保：配置/etc/hosts映射 IP地址 主机名

• 3、确保：mysql数据库服务启动，hadoop集群启动，zk集群启动

• 4、确保：mysql数据库创建ds数据库

mysql> CREATE DATABASE dolphinscheduler DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
mysql> GRANT ALL PRIVILEGES ON dolphinscheduler.* TO 'dolphinscheduler'@'%' IDENTIFIED BY 'dolphinscheduler';
mysql> flush privileges;

1、先解压 源码编译好的 ds 海豚调度 的 bin 二进制包

tar -zxvf /opt/software/apache-dolphinscheduler-1.3.9-bin.tar.gz -C /opt/module/

2、进入解压后的目录

cd /opt/module/apache-dolphinscheduler-1.3.9-bin

3、开始配置

3.1 数据源

vim /opt/module/apache-dolphinscheduler-1.3.9-bin/conf/datasource.properties

# mysql example
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://hadoop102:3306/dolphinscheduler?characterEncoding=UTF-8&allowMultiQueries=true
spring.datasource.username=dolphinscheduler
spring.datasource.password=dolphinscheduler

3.2 环境变量

vim /opt/module/apache-dolphinscheduler-1.3.9-bin/conf/env/dolphinscheduler_env.sh

# JAVA_HOME
export JAVA_HOME=/opt/module/jdk1.8.0_212# HADOOP_HOME
export HADOOP_HOME=/opt/module/hadoop-3.1.3
export HADOOP_CONF_DIR=/opt/module/hadoop-3.1.3/etc/hadoop# DATAX_HOME
export DATAX_HOME=/opt/module/datax# HIVE_HOME
export HIVE_HOME=/opt/module/apache-hive-3.1.2-bin# SPARK_HOME
export SPARK_HOME=/opt/module/spark-3.0.0-bin-hadoop3.2

3.3 安装配置文件

vim /opt/module/apache-dolphinscheduler-1.3.9-bin/conf/config/install_config.conf

# postgresql or mysql

# db address and port
dbhost="hadoop102:3306"# db username

# if S3，write S3 address，HA，for example ：s3a://dolphinscheduler，
# Note，s3 be sure to create the root directory /dolphinscheduler
defaultFS="hdfs://hadoop102:8020"# if resourceStorageType is S3, the following three configuration is required, otherwise please ignore
s3Endpoint="http://192.168.xx.xx:9010"
s3AccessKey="xxxxxxxxxx"

resourceManagerHttpAddressPort="8088"# if resourcemanager HA is enabled, please set the HA IPs; if resourcemanager is single, keep this value empty
yarnHaIps="" #"192.168.xx.xx,192.168.xx.xx"# if resourcemanager HA is enabled or not use resourcemanager, please keep the default value; If resourcemanager is single, you only need to replace ds1 to actual resourcemanager hostname

# Note: if ssh port is not default, modify here
sshPort="22"# run master machine
# Note: list of hosts hostname for deploying master
masters="hadoop102"
#masters="hadoop103"# run worker machine
# note: need to write the worker group name of each worker, the default value is "default"
#workers="hadoop102:default,hadoop103:default,hadoop104:default"
workers="hadoop103:default,hadoop104:default"# run alert machine
# note: list of machine hostnames for deploying alert server
alertServer=""# run api machine
# note: list of machine hostnames for deploying api server
apiServers="hadoop102"

注意 yarn 配置：

• 如果是yarn HA高可用，那么配置高可用地址，需要置空单点配置
• 如果yarn单点，需要置空高可用配置

# if resourcemanager HA is enabled, please set the HA IPs; if resourcemanager is single, keep this value empty
yarnHaIps="" #"192.168.xx.xx,192.168.xx.xx"# if resourcemanager HA is enabled or not use resourcemanager, please keep the default value; If resourcemanager is single, you only need to replace ds1 to actual resourcemanager hostname
singleYarnIp="hadoop103"

示例1（yarn HA 高可用）：

yarnHaIps="hadoop102,hadoop103"
singleYarnIp=""

示例2（yarn 单点）：

yarnHaIps=""
singleYarnIp="hadoop103"

4、开始安装

sh /opt/module/apache-dolphinscheduler-1.3.9-bin/install.sh

5、浏览器访问 DS 海豚调度 Web UI
