Standalone Deployment and Upgrade

• Official website: DolphinDB
• Or you can download DolphinDB with a shell command:

wget https://www.dolphindb.com/downloads/DolphinDB_Linux64_V${release}.zip -O dolphindb.zip

${release} refers to the version of DolphinDB server. For example, you can download Linux64 server 2.00.11.3 with the following command:

wget https://www.dolphindb.com/downloads/DolphinDB_Linux64_V2.00.11.3.zip -O dolphindb.zip

To download the ABI or JIT version of DolphinDB server, add "ABI" or "JIT" after the version number (linked with an underscore). For example, you can download Linux64 ABI server 2.00.11.3 with the following command:

wget https://www.dolphindb.com/downloads/DolphinDB_Linux64_V2.00.11.3_ABI.zip -O dolphindb.zip

Download Linux64 JIT server 2.00.11.3 with the following command:

wget https://www.dolphindb.com/downloads/DolphinDB_Linux64_V2.00.11.3_JIT.zip -O dolphindb.zip

• Then extract the installation package to the specified directory (/path/to/directory):

unzip dolphindb.zip -d </path/to/directory>

Note: The directory name cannot contain any space characters, otherwise the startup of the data node will fail.

If you have obtained the Enterprise Edition license, use it to replace the following file:

/DolphinDB/server/dolphindb.lic

Otherwise, you can continue to use the community version of DolphinDB, which allows up to 2 nodes, 2 CPU cores and 8 GB RAM per node.

Navigate to the folder /DolphinDB/server/. The file permissions need to be modified for the first startup. Execute the following shell command:

chmod +x dolphindb

• Linux console mode:

./dolphindb

The default port number of the system is 8848. To change it (e.g., to 8900), use the following command line:

./dolphindb -localSite localhost:8900:local8900

• Linux background mode:

sh startSingle.sh

To check whether the node was successfully started, execute the following shell command:

ps aux|grep dolphindb

The following information indicates a successful startup:

Enter the deployment server IP address and port number (8848 by default) in the browser to navigate to the DolphinDB Web. The server address (ip:port) used in this tutorial is 10.0.0.82:8848. Below is the web interface.

Note: If the browser and DolphinDB are not deployed on the same server, you should turn off the firewall or open the corresponding port beforehand.

• Official website: DolphinDB

• Extract the installation package to the specified directory:

C:\DolphinDB

Note: The directory name cannot contain any space characters, otherwise the startup of the data node will fail. For example, do not extract it to the Program Files folder on Windows.

If you have obtained the Enterprise Edition license, use it to replace the following file:

C:\DolphinDB\server\dolphindb.lic

Otherwise, you can continue to use the community version of DolphinDB, which allows up to 8GB of memory use for 20 years.

Navigate to the folder C:\DolphinDB\server:

• Windows console mode:

Double click to execute dolphindb.exe:

The default port number of the system is 8848. You can change it by modifying the localSite parameter in config file dolphindb.cfg.

• Windows background mode:

Double click to execute backgroundSingle.vbs, and check DolphinDB process in your Task Manager.

Or you can check the process in Command Prompt with the following command.

tasklist|findstr "dolphindb"

Enter the deployment server IP address and port number (8848 by default) in the browser to navigate into the DolphinDB Web. The server address (ip:port) used in this tutorial is 10.0.0.82:8848. Below is the web interface.

Note: If the browser and DolphinDB are not deployed on the same server, you should turn off the firewall or open the corresponding port beforehand.

Step 1: Close the Server

Navigate to the folder /DolphinDB/server/clusterDemo to execute the following command:

./stopAllNode.sh

Step 2: Backup the Metadata

The default directory to save the metadata for a standalone mode is:

/DolphinDB/server/local8848/dfsMeta/

/DolphinDB/server/local8848/storage/CHUNK_METADATA/

You can execute the following command to back up the metadata:

mkdir backup
cp -r local8848/dfsMeta/ backup/dfsMeta
cp -r local8848/storage/CHUNK_METADATA/ backup/CHUNK_METADATA

Note: If the backup files are not in the above default directories, check the directories specified by the configuration parameters dfsMetaDir and chunkMetaDir. If the configuration parameters are not modified but the configuration parameter volumes is specified, then you can find the CHUNK_METADATA under the volumes directory.

Step 3: Upgrade
Note: When the server is upgraded to a certain version, the plugin should also be upgraded to the corresponding version.

• Online Upgrade

Navigate to the folder /DolphinDB/server/clusterDemo to execute the following command:

./upgrade.sh

The following prompt is returned:

Type "y" and press Enter:

Type "1" and press Enter:

Type a version number and press Enter. To upgrade to version 2.00.9.1, for example, enter 2.00.9.1 and press Enter. The following prompt indicates a successful upgrade.

• Offline Upgrade

Download a new version of server package from DolphinDB website

Upload the installation package to /DolphinDB/server/clusterDemo. Take version 2.00.9.1 as an example.

Navigate to the folder /DolphinDB/server/clusterDemo to execute the following command:

./upgrade.sh

The following prompt is returned:

Type "y" and press Enter:

Type "2" and press Enter:

Type a version number and press Enter. To upgrade to version 2.00.9.1, for example, enter 2.00.9.1 and press Enter. The following prompt indicates a successful upgrade.

Step 4: Restart the Server

Navigate to the folder /DolphinDB/server to start the server with the following command:

sh startSingle.sh

Open the web interface and execute the following script to check the current version of DolphinDB.

version()

Step 1: Close the Server

• In console mode, close the foreground process.
• In background mode, close DolphinDB process from Task Manager.

Step 2: Back up the Metadata

The default directory to save the metadata for a standalone mode is:

C:\DolphinDB\server\local8848\dfsMeta\

C:\DolphinDB\DolphinDB\server\local8848\storage\CHUNK_METADATA\

Create a new folder backup under C:\DolphinDB, and copy the following files to it:

• file dfsMeta under C:\DolphinDB\server\local8848
• file CHUNK_METADATA under C:\DolphinDB\server\local8848\storage

Note: If the backup files are not in the above default directories, check the directories specified by the configuration parameters dfsMetaDir and chunkMetaDir. If the configuration parameters are not modified but the configuration parameter volumes is specified, then you can find the CHUNK_METADATA under the volumes directory.

Step 3: Upgrade

• Download a new version of server package from DolphinDB website
• Replace the existing server with all files (except dolphindb.cfg and dolphindb.lic) in the current \DolphinDB\server folder.

Note: When the server is upgraded to a certain version, the plugin should also be upgraded to the corresponding version.

Step 4: Restart the Server

Double click to execute dolphindb.exe.

Open the web interface and execute the following script to check the current version of DolphinDB.

version()

Replace an existing license file with a new one.

License file path on Linux:

/DolphinDB/server/dolphindb.lic

License file path on Windows:

C:\DolphinDB\server\dolphindb.lic

• Online Update

Execute the following script in web interface:

updateLicense()

Note:

• The client name of the license cannot be changed.
• The number of nodes, memory size, and the number of CPU cores cannot be smaller than the original license.
• The update takes effect only on the node where the function is executed. Therefore, in a cluster mode, the function needs to be run on all controllers, agents, data nodes, and compute nodes.
• The license type must be either commercial (paid) or free.

• Offline Update

Restart DolphinDB server to complete the updates.
