How to deploy a DataV-Board dashboard offline-DataV(DataV)-阿里云帮助中心

Private deployment lets you package and download a complete dashboard developed with DataV-Board 7.0. You can then install and run this dashboard on your corporate intranet. For example, if your corporate intranet has a database that is not accessible from the public network, an online dashboard cannot connect to it. Private deployment solves this problem.

Server configuration requirements for private deployment

The minimum system and hardware requirements are as follows:

A 64-bit Linux system compatible with CentOS 7.0
An 8-core, 4 GHz x86_64 or ARM64 processor, or one with equivalent performance
16 GB of memory
At least 100 GB of disk space
Docker version 18.09.9 installed on the system

Limits

Only Premium Edition users can use the private deployment feature.
Private deployments do not include map tile data.
Private deployments support the following data source types: HTTP API, MySQL, SQL Server, Oracle, PostgreSQL, and static data.

Note
During a private deployment, the packaged dashboard retains its original data source type and related configurations.

Obtain a private deployment package

Go to the DataV Product Purchase page and purchase the DataV Premium Edition.
Log on to the DataV console.
On the My Visualizations page, select a visualization application and click Edit.
In the PC canvas editor, click the Download Page icon in the upper-right corner of the page.

In the Package Screen dialog box, follow the prompts to download the deployment package and the visualization application package.
1. Click Deployment Package to go to the download page for the 7.x runtime environment deployment package.
2. Click Packaging Records to go to the visualization application packaging page. Click Start Packaging to create a packaging task for the current screen. After the packaging is successful, click Download.
Deploy the DataV service
1. You can upload the downloaded runtime environment compressed package to your server.
2. You can create a new folder on the server.
  
  For example, you can run the mkdir -p datav_runtime command to create a folder named datav_runtime.
3. You can use the unzip command to decompress runtime.zip into the datav_runtime folder.
```
unzip runtime.zip -d datav_runtime
```
  Note
  Make sure that you have downloaded runtime.zip to the current folder or that you know its path.
4. Copy runtime.key to the datav_runtime folder.
```
cp path/to/runtime.key datav_runtime/
```
  Note
  Make sure that the runtime.key file exists in the current folder or the specified path.
5. You can start and check the service. By default, the service is stopped.
  Go to the datav_runtime folder and run the following commands:
```
cd datav_runtime
```
  - Start the service
    ./datav start
    
    Note
    If you receive a "Permission denied" fault when you run ./datav start, you must grant execution permission. First, run chmod +x datav to modify the permission. Then, run ./datav start to start the program again.
  - Stop the service
```
./datav stop
```
  - Restart the service
```
./datav restart
```
  - Check the service status
```
./datav list
```
  - View the startup log
```
./datav logs <NAME> # You can get <NAME> by running ./datav list
```
  - View the operational log
```
docker exec -it -w /home/admin/honeycomb/logs datav-service bash
```
6. Modify the configuration
  You can create a config.yaml file in the ./datav folder. The optional configurations are as follows:
```
DataDir: "" # The path where data is saved. The default is the current folder.
MainPort: 7001 # The service port.
```

Reset password

Log on to the server and run the following command:

./datav start reset-password -- <UserName> [<Password>]

Note

<UserName>: The username for which you want to reset the password.
[<Password>]: An optional new password. If you do not specify this parameter, the password is reset to the default password.
