Standalone Deployment

1、Install basic softwares (please install required softwares by yourself)

PostgreSQL (8.2.15+) or MySQL (5.7) : Choose One, JDBC Driver 5.1.47+ is required if MySQL is used
JDK (1.8+) : Required. Double-check configure JAVA_HOME and PATH environment variables in /etc/profile
ZooKeeper (3.4.6+) ：Required
Hadoop (2.6+) or MinIO ：Optional. If you need resource function, for Standalone Deployment you can choose a local directory as the upload destination (this does not need Hadoop deployed). Of course, you can also choose to upload to Hadoop or MinIO.

 Tips：DolphinScheduler itself does not rely on Hadoop, Hive, Spark, only use their clients to run corresponding task.

2、Download the binary tar.gz package.

Please download the latest version installation package to the server deployment directory. For example, use /opt/dolphinscheduler as the installation and deployment directory. Download address: Download, download package, move to deployment directory and uncompress it.

# Create the deployment directory. Please do not choose a high-privilege directory such as /root or /home.
mkdir -p /opt/dolphinscheduler;
cd /opt/dolphinscheduler;

# uncompress
tar -zxvf apache-dolphinscheduler-incubating-1.3.5-dolphinscheduler-bin.tar.gz -C /opt/dolphinscheduler;

# rename
mv apache-dolphinscheduler-incubating-1.3.5-dolphinscheduler-bin  dolphinscheduler-bin

3、Create deployment user and assign directory operation permissions

Create a deployment user, and be sure to configure sudo secret-free. Here take the creation of a dolphinscheduler user as example.

# To create a user, you need to log in as root and set the deployment user name.
useradd dolphinscheduler;

# Set the user password, please modify it yourself.
echo "dolphinscheduler123" | passwd --stdin dolphinscheduler

# Configure sudo secret-free
echo 'dolphinscheduler  ALL=(ALL)  NOPASSWD: NOPASSWD: ALL' >> /etc/sudoers
sed -i 's/Defaults    requirett/#Defaults    requirett/g' /etc/sudoers

# Modify the directory permissions so that the deployment user has operation permissions on the dolphinscheduler-bin directory
chown -R dolphinscheduler:dolphinscheduler dolphinscheduler-bin

 Notes：
 - Because the task execution is based on 'sudo -u {linux-user}' to switch among different Linux users to implement multi-tenant job running, so the deployment user must have sudo permissions and is secret-free. If beginner learners don’t understand, you can ignore this point for now.
 - Please comment out line "Default requiretty", if it present in "/etc/sudoers" file. 
 - If you need to use resource upload, you need to assign user the permission to operate the local file system, HDFS or MinIO.

4、SSH secret-free configuration

Switch to the deployment user and configure SSH local secret-free login

su dolphinscheduler;

ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys

Note: If configure successed, the dolphinscheduler user does not need to enter a password when executing the command ssh localhost.

5、Database initialization

Log in to the database, the default database type is PostgreSQL. If you choose MySQL, you need to add the mysql-connector-java driver package to the lib directory of DolphinScheduler.

mysql -uroot -p

After log into the database command line window, execute the database initialization command and set the user and password.

Note: {user} and {password} need to be replaced with a specific database username and password.

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

Create tables and import basic data

Modify the following configuration in datasource.properties under the conf directory.

  vi conf/datasource.properties

If you choose Mysql, please comment out the relevant configuration of PostgreSQL (vice versa), you also need to manually add the [[mysql-connector-java driver jar] (https://downloads.mysql.com/archives/c-j/)] package to lib directory, and then configure the database connection information correctly.

  #postgre
  #spring.datasource.driver-class-name=org.postgresql.Driver
  #spring.datasource.url=jdbc:postgresql://localhost:5432/dolphinscheduler
  # mysql
  spring.datasource.driver-class-name=com.mysql.jdbc.Driver
  spring.datasource.url=jdbc:mysql://xxx:3306/dolphinscheduler?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true     # Replace the correct IP address
  spring.datasource.username=xxx						# replace the correct {username} value
  spring.datasource.password=xxx						# replace the correct {password} value

After modifying and saving, execute create-dolphinscheduler.sh in the script directory.

sh script/create-dolphinscheduler.sh

Note: If you execute the above script and report "/bin/java: No such file or directory" error, please configure JAVA_HOME and PATH variables in /etc/profile.

6、Modify runtime parameters.

Modify the environment variable in dolphinscheduler_env.sh file under 'conf/env' directory (take the relevant software installed under '/opt/soft' as example)

    export HADOOP_HOME=/opt/soft/hadoop
    export HADOOP_CONF_DIR=/opt/soft/hadoop/etc/hadoop
    #export SPARK_HOME1=/opt/soft/spark1
    export SPARK_HOME2=/opt/soft/spark2
    export PYTHON_HOME=/opt/soft/python
    export JAVA_HOME=/opt/soft/java
    export HIVE_HOME=/opt/soft/hive
    export FLINK_HOME=/opt/soft/flink
    export DATAX_HOME=/opt/soft/datax/bin/datax.py
    export PATH=$HADOOP_HOME/bin:$SPARK_HOME2/bin:$PYTHON_HOME:$JAVA_HOME/bin:$HIVE_HOME/bin:$PATH:$FLINK_HOME/bin:$DATAX_HOME:$PATH

    ```

 `Note: This step is very important. For example, JAVA_HOME and PATH must be configured. Those that are not used can be ignored or commented out. If you can not find dolphinscheduler_env.sh, please run ls -a.`

Create JDK soft link to /usr/bin/java (still JAVA_HOME=/opt/soft/java as an example)
```
sudo ln -s /opt/soft/java/bin/java /usr/bin/java
```

Modify the parameters in the one-click deployment config file conf/config/install_config.conf, pay special attention to the configuration of the following parameters.

# choose mysql or postgresql
dbtype="mysql"

# Database connection address and port
dbhost="localhost:3306"

# database name
dbname="dolphinscheduler"

# database username
username="xxx"

# database password
# NOTICE: if there are special characters, please use the \ to escape, for example, `[` escape to `\[`
password="xxx"

# Zookeeper address, localhost:2181, remember port 2181
zkQuorum="localhost:2181"

# Note: the target installation path for dolphinscheduler, please do not use 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="dolphinscheduler"

# alert config，take QQ email for example
# mail protocol
mailProtocol="SMTP"

# mail server host
mailServerHost="smtp.qq.com"

# mail server port
# note: Different protocols and encryption methods correspond to different ports, when SSL/TLS is enabled, port may be different, make sure the port is correct.
mailServerPort="25"

# mail sender
mailSender="xxx@qq.com"

# mail user
mailUser="xxx@qq.com"

# mail sender password
# note: The mail.passwd is email service authorization code, not the email login password.
mailPassword="xxx"

# Whether TLS mail protocol is supported,true is supported and false is not supported
starttlsEnable="true"

# Whether TLS mail protocol is supported,true is supported and false is not supported。
# note: only one of TLS and SSL can be in the true state.
sslEnable="false"

# note: sslTrust is the same as mailServerHost
sslTrust="smtp.qq.com"

# resource storage type：HDFS,S3,NONE
resourceStorageType="HDFS"

# here is an example of saving to a local file system
# Note: If you want to upload resource file(jar file and so on)to HDFS and the NameNode has HA enabled, you need to put core-site.xml and hdfs-site.xml of hadoop cluster in the installPath/conf directory. In this example, it is placed under /opt/soft/dolphinscheduler/conf, and Configure the namenode cluster name; if the NameNode is not HA, modify it to a specific IP or host name.
defaultFS="file:///data/dolphinscheduler"

# if not use hadoop resourcemanager, please keep default value; if resourcemanager HA enable, please type the HA ips ; if resourcemanager is single, make this value empty
# Note: For tasks that depend on YARN to execute, you need to ensure that YARN information is configured correctly in order to ensure successful execution results.
yarnHaIps="192.168.xx.xx,192.168.xx.xx"

# if resourcemanager HA enable or not use resourcemanager, please skip this value setting; If resourcemanager is single, you only need to replace yarnIp1 to actual resourcemanager hostname.
singleYarnIp="yarnIp1"

# 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="/data/dolphinscheduler"

# specify the user who have permissions to create directory under HDFS/S3 root path
hdfsRootUser="hdfs"

# On which machines to deploy the DS service, choose localhost for this machine
ips="localhost"

# ssh port, default 22
# Note: if ssh port is not default, modify here
sshPort="22"

# run master machine
masters="localhost"

# run worker machine
workers="localhost"

# run alert machine
alertServer="localhost"

# run api machine
apiServers="localhost"

Attention: if you need upload resource function, please execute below command:


sudo mkdir /data/dolphinscheduler
sudo chown -R dolphinscheduler:dolphinscheduler /data/dolphinscheduler

7、Automated Deployment

Switch to the deployment user and execute the one-click deployment script

sh install.sh

Note:
For the first deployment, the following message appears in step 3 of `3, stop server` during operation. This message can be ignored.
sh: bin/dolphinscheduler-daemon.sh: No such file or directory

After script completed, the following 5 services will be started. Use jps command to check whether the services started (jps comes with java JDK)

    MasterServer         ----- master service
    WorkerServer         ----- worker service
    LoggerServer         ----- logger service
    ApiApplicationServer ----- api service
    AlertServer          ----- alert service

If the above services started normally, the automatic deployment is successful.

After the deployment is success, you can view logs. Logs stored in the logs folder.

 logs/
    ├── dolphinscheduler-alert-server.log
    ├── dolphinscheduler-master-server.log
    |—— dolphinscheduler-worker-server.log
    |—— dolphinscheduler-api-server.log
    |—— dolphinscheduler-logger-server.log

8、login

Access the front page address, interface IP (self-modified) http://192.168.xx.xx:12345/dolphinscheduler

9、Start and stop service

Stop all services

sh ./bin/stop-all.sh
Start all services

sh ./bin/start-all.sh
Start and stop master service

sh ./bin/dolphinscheduler-daemon.sh start master-server
sh ./bin/dolphinscheduler-daemon.sh stop master-server
