Downloading the Client

Scenarios

A default client is provided for MRS clusters. You can manage the cluster, run services, and perform secondary development using this client. Before using the client, you need to download the client software package.

Procedure

1. Log in to FusionInsight Manager.
2. Choose Cluster > Name of the desired cluster > Dashboard > More > Download Client.

   The Download Cluster Client dialog box is displayed.

3. Select a type in the Select Client Type dialog box.
   • The Complete Client type indicates that the package contains scripts, compilation files, and configuration files.
   • The Configuration Files Only type indicates that the package contains only the client configuration file.

     This type is applicable to application development tasks. For example, it can be used in the following scenario: All client files are downloaded and installed and the MRS cluster administrator modifies the service configuration on FusionInsight Manager. The developer needs to update the client configuration files.

   

   There are two platform types: x86_64 and aarch64, which can be installed on the x86 and TaiShan nodes respectively. By default, the platform type of the downloaded client is the same as that of the server.

4. Determine whether to generate a client software package file on the cluster node.
   • If yes, select Save to Path and click OK to generate the client file.

     After the file is generated, it is stored in the /tmp/FusionInsight-Client/ directory on the primary management node by default. You can also store the client file in other directories, and user omm has the read, write, and execute permissions on the directory. If the client file already exists in the path, the existing client file will be replaced.

     After the file is generated, copy the obtained package to another directory, as user omm or client installation user, for example, the /opt/Bigdata/client directory.

   • If no, click OK and download the client file to the local PC.

     Download the client software package, and wait until the download is complete.

   After the client is successfully downloaded, install the client by referring to Installing a Client.
