一、相关连接
1、dolphinscheduler单机部署说明
2、dolphinschedulerd的git源码
3、aws的s3访问说明
4、aws的s3 Endpoint说明
二、部署目标
本文dolphinscheduler的部署目标是实现存储和计算完全分离，数据和资源存储在s3上、计算采用emr集群进行动态扩充管理。
三、流程
3.1 下载源码并修改
下载源码
git clone -b 1.3.6-release https://github.com/apache/dolphinscheduler.git
cp dolphinscheduler dolphinscheduler_debug
cd dolphinscheduler_debug
修改源码，s3AccessKey和s3SecretKey的值可能不一致
sed -i "s/fs.s3a.access.key/fs.s3.awsAccessKeyId/g" `grep fs.s3a.access.key -rl /home/hadoop/workspace/dolphinscheduler_debug`
sed -i "s/fs.s3a.secret.key/fs.s3.awsSecretAccessKey/g" `grep fs.s3a.secret.key -rl /home/hadoop/workspace/dolphinscheduler_debug`
修改说明s3配置的key可能不一样：
以下是否修改视情况而定
vi ./dolphinscheduler-common/src/main/java/org/apache/dolphinscheduler/common/utils/HadoopUtils.java
public static final String resourceUploadPath = PropertyUtils.getString(RESOURCE_UPLOAD_PATH, "/dolphinscheduler");
编译
./mvnw clean install -Prelease
3.2 配置
dolphinscheduler运行用户必须改为是emr的hadoop账号，省事
主要参考dolphinscheduler单机部署说明文档
- 重要流程
1、上传mysql-connector-java-5.1.49.jar到 lib目标
2、配置conf/datasource.properties
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://xxxxxxxxx:3306/dolphinscheduler?characterEncoding=UTF-8&allowMultiQueries=true
spring.datasource.username=dolphinscheduler
spring.datasource.password=yyyyyy
3、配置conf/env/dolphinscheduler_env.sh
emr在配置时候集成了hadoop、spark、hive，所以就只配置了python路径
export PYTHON_HOME=/usr/bin/python3.7
export PATH=$PYTHON_HOME:$PATH
4、配置conf/config/install_config.conf
# NOTICE : If the following config has special characters in the variable `.*[]^${}\+?|()@#&`, Please escape, for example, `[` escape to `\[`
# postgresql or mysql
dbtype="mysql"

# resource storage type: HDFS, S3, NONE
resourceStorageType="S3"
# if resourceStorageType is HDFS，defaultFS write namenode address，HA you need to put core-site.xml and hdfs-site.xml in the conf directory.
# if S3，write S3 address，HA，for example ：s3a://dolphinscheduler，
# Note，s3 be sure to create the root directory /dolphinscheduler
# defaultFS="hdfs://mycluster:8020"
defaultFS="s3a://cccc-dolphinscheduler"
# if resourceStorageType is S3, the following three configuration is required, otherwise please ignore

# if resourcemanager HA is enabled, please set the HA IPs; if resourcemanager is single, keep this value empty
yarnHaIps="172.10.170.26"
# 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="172.10.170.26"
# resource store on HDFS/S3 path, resource file will store to this hadoop hdfs path, self configuration, please make sure the directory exists on hdfs and have read write permissions. "/dolphinscheduler" is recommended

5、其他相关操作
1、上传下载文件（rz/sz）
sudo yum -y install lrzsz
2、修改免密（hadoop）
#echo 'hadoop ALL=(ALL) NOPASSWD: NOPASSWD: ALL' >> /etc/sudoers
ssh-keygen -t rsa
cd .ssh/
cat id_rsa.pub >> authorized_keys
cd ..
chmod 700 -R .ssh/
ssh localhost
3、文件
sudo bash
mkdir -p /opt/dolphinscheduler;
cd /opt/dolphinscheduler;
rz df的bin包
tar -zxvf apache-dolphinscheduler-1.3.6-bin.tar.gz -C /opt/dolphinscheduler;
mv apache-dolphinscheduler-1.3.6-bin dolphinscheduler-bin
chown -R hadoop:hadoop dolphinscheduler-bin
mkdir -p /data/dolphinscheduler
chown -R hadoop:hadoop /data/dolphinscheduler
4、配置
rz mysql驱动
5、sh命令
一键部署：sh install.sh
一键停止：sh ./bin/stop-all.sh
一键开始：sh ./bin/start-all.sh
四、web
http://xx.xx.xx.xxx:12345/dolphinscheduler/
默认用户：admin：dolphinscheduler123
进入后按需创建租户：emr创建hadoop租户
然后创建普通用户，并指定hadoop租户
