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"
# db config

password="yyyyyy"
# zk cluster
zkQuorum="localhost:2181"
# Note: the target installation path for dolphinscheduler, please not config as the same as the current path (pwd)
installPath="/opt/soft/dolphinscheduler"
# deployment user
# Note: the deployment user needs to have sudo privileges and permissions to operate hdfs. If hdfs is enabled, the root directory needs to be created by itself
deployUser="hadoop"
# alert config
# mail server host
mailServerHost="smtp.exmail.qq.com"
# mail server port
# note: Different protocols and encryption methods correspond to different ports, when SSL/TLS is enabled, make sure the port is correct.
mailServerPort="25"
# sender
mailSender="xxxxxxxxxx"
# user
mailUser="xxxxxxxxxx"
# sender password
# note: The mail.passwd is email service authorization code, not the email login password.
mailPassword="xxxxxxxxxx"
# TLS mail protocol support

# SSL mail protocol support
# only one of TLS and SSL can be in the true state.
sslEnable="false"
#note: sslTrust is the same as mailServerHost
sslTrust="smtp.exmail.qq.com"
# 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
# s3Endpoint="http://192.168.xx.xx:9010"
s3Endpoint="http://s3.us-west-2.amazonaws.com"
s3AccessKey="awddsasdaasd"
s3SecretKey="aaa/aqw/9hiA5ExnY"
# 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
resourceUploadPath="/cccc-dolphinscheduler/"
# who have permissions to create directory under HDFS/S3 root path
# Note: if kerberos is enabled, please config hdfsRootUser=
hdfsRootUser="hdfs"
# kerberos config
# whether kerberos starts, if kerberos starts, following four items need to config, otherwise please ignore
kerberosStartUp="false"
# kdc krb5 config file path
krb5ConfPath="$installPath/conf/krb5.conf"
# keytab username
keytabUserName="hdfs-mycluster@ESZ.COM"
# username keytab path
keytabPath="$installPath/conf/hdfs.headless.keytab"
# api server port
apiServerPort="12345"
# install hosts
# Note: install the scheduled hostname list. If it is pseudo-distributed, just write a pseudo-distributed hostname
ips="localhost"
# ssh port, default 22
# Note: if ssh port is not default, modify here
sshPort="22"
# run master machine
# Note: list of hosts hostname for deploying master
masters="localhost"
# run worker machine
# note: need to write the worker group name of each worker, the default value is "default"
workers="localhost:default"
# run alert machine
# note: list of machine hostnames for deploying alert server
alertServer="localhost"
# run api machine
# note: list of machine hostnames for deploying api server
apiServers="localhost"
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
