Due to the richness of its components, DataSphereStudio can be installed as a simple version or a standard version, different with other softwares. The differences are mentioned as below:
Simple Version Minimal environment dependencies and only basic components need to be prepared：Linkis、JAVA、MYSQL、Nginx. Then you can immediately enjoy the integrated Scriptis(for data development), real-time workflow execution, visualization, email delivery, datacheck and eventcheck services. Click to enter the simple version DSS environment configuration preparation
Standard Version DSS also implements the integration of many external systems, such as Qualitis and Azkaban. If you want to use these external systems, you need to install and start the Qualities and Azkaban services before installing the simple version, and ensure that they can provide services properly. The IP and port of the corresponding service should be specified in the configuration. Click me to enter the standard version DSS environment configuration preparation
DSS environment configuration can be divided into three steps, including basic software installation, backend environment configuration, and frontend environment configuration. The details are as below:
Linkis standard version (above 0.9.4). How to install Linkis
JDK (above 1.8.0_141). How to install JDK
MySQL (5.5+). How to Install MySQL
Nginx. How to Install Nginx
sudo useradd hadoop
(Note: It is better for users to gain sudo permission and login to the machine without password). How to configure SSH passwordless login
On the DSS release page click here to enter the download page, download the corresponding installation package. First decompress the installation package to the installation directory and then modify the configuration of the decompressed file
tar -xvf wedatasphere-dss-x.x.x-dist.tar.gz
Note: If the installation package was compiled by the user, you need to copy the visualis-server installation package to the share/visualis-server folder in the DSS installation directory for automated installation.
vi conf/config.sh
<!--Note: The following are the basic DSS configuration items. If you want to experience more enterprise features, please install the standard DSS.-->
deployUser=hadoop #Specify the deployment user
DSS_INSTALL_HOME=/appcom/Install/DSS #Specify the DSS installation directory
EUREKA_INSTALL_IP=127.0.0.1 #Linkis EUREKA Service host IP address

Click release to download the corresponding installation package and extract it to the installation directory:
unzip wedatasphere-dss-web-x.x.x-dist.zip
Note: If the DSS frontend installation package was compiled by the user, you need to copy the visualis frontEnd installation package to the dss/visualis folder in the DSS frontEnd-end installation directory for automated installation.
Enter the frontend working directory and edit the file in this directory
vi conf/config.sh
Change the dss frontend port and backend linkis gateway IP address/port
# Configuring frontEnd-end ports
dss_port="8088"
# URL of the backend linkis gateway
linkis_url="http://127.0.0.1:9001"
# dss ip address
dss_ipaddr=$(ip addr | awk '/^[0-9]+: / {}; /inet.*global/ {print gensub(/(.*)\/(.*)/, "\\1", "g", $2)}'|awk 'NR==1')
The environment is ready, click me to enter **4. Installation and use
The standard DSS environment preparation is also divided into three parts, the frontEnd-end and back-end basic software installation, back-end environment preparation, and frontEnd-end environment preparation. The details are as follows:
Linkis standard version (above 0.9.4), How to install Linkis
JDK (above 1.8.0_141), How to install JDK
MySQL (5.5+), How to Install MySQL
Nginx, How to Install Nginx
Qualitis, How to Install Qualitis
Azkaban, How to Install Azkaban
Note: To support Azkaban scheduling, linkis-jobtype needs to be installed. Please click the Linkis jobType installation document.
sudo useradd hadoop
Note: It is best for users to have sudo permissions and log in to this machine without password. How to configure SSH passwordless login
From the DSS released click here to enter the download page, download the corresponding installation package. First decompress the installation package to the installation directory and modify the configuration of the decompressed file

Click releaseto select the installation package to download and extract it in the installation directory:
unzip wedatasphere-DataSphereStudio-x.x.x-dist.zip
Note: If the DSS frontEnd-end installation package is compiled by the user, you need to copy the visualis frontEnd installation package to the dss/visualis folder in the DSS frontEnd installation directory for automated installation.
Enter the frontEnd working directory and edit in this directory
vi conf/config.sh
Change the dss frontEnd port and BackEnd linkis gateway IP address and port
# Configuring frontEnd-end ports
dss_port="8088"
# URL of the backend linkis gateway
linkis_url="http://127.0.0.1:9001"
# dss ip address
dss_ipaddr=$(ip addr | awk '/^[0-9]+: / {}; /inet.*global/ {print gensub(/(.*)\/(.*)/, "\\1", "g", $2)}'|awk 'NR==1')
The environment is ready, click me to enter Four Installation and use
sh bin/install.sh
The install.sh script will ask you about the installation mode. The installation mode is the simple mode or the standard mode. Please select the appropriate installation mode according to your prepared environment. Both the simple mode and the standard mode will check the mysql service. The standard mode will also check the Qualities service and the Azkaban service.
The install.sh script will ask if you need to initialize the database and import metadata. Because I am worried that the user repeatedly executes the install.sh script to clear the user data in the database, when the install.sh is executed, the user will be asked whether to initialize the database and import metadata. You must select Yes for the first installation.
The install.sh script will ask you if you need to initialize the library tables that davinci depends on. If you have not installed davinci, you need to initialize the table. If you have already installed davinci, you don't need to initialize it again. Because I worry that the user will clear the davinci data already installed in mysql, so when install.sh is executed, the user will be asked if it needs to be initialized. You must select Yes for the first installation.
Check whether the installation is successful by viewing the log information printed on the console. If there is an error message, you can view the specific cause of the error. You can also get answers to your questions by viewing our FAQ.
Execute the following command in the installation directory to start all services:
./bin/start-all.sh > start.log 2>start_error.log
You can view the success of the service startup on the Eureka interface, and check the method:
Use http://${EUREKA_INSTALL_IP}:${EUREKA_PORT}, Open it in your browser to see if the service is successfully registered.
If you did not specify EUREKA_INSTALL_IP and EUREKA_INSTALL_IP in config.sh, the HTTP address is: http://127.0.0.1:20303
As shown in the figure below, if the following microservices appear on your Eureka homepage, the services are successfully started and services can be provided normally:
Click release to select the installation package to download and extract it in the installation directory:
unzip wedatasphere-dss-web-x.x.x-dist.zip
Enter the frontEnd-end working directory and execute the installation script
sh bin/install.sh
After execution can be accessed directly through Google Chrome：
http://dss_ipaddr:dss_port
dss_port is the port configured in config.sh, and dss_ipaddr is the IP of the installation machine.
If the access failed: You can check the log of install.log to see which step went wrong
If you want to manually install the frontend, the steps are as follows:
sudo vi /etc/nginx/conf.d/dss.conf
Add the following configurations:
