Installing an Agent

Install the agent on the node suitable for your service scenario.

3. Run the following command to access the directory where the agent installation package xxx.tar.gz is stored:

   cd Directory_containing_agent_installation_package

4. Run the following command to decompress the installation package xxx.tar.gz:

   tar -xvf xxx.tar.gz

5. Run the following command to switch to the directory containing the decompressed files:

   cd Decompressed_package_directory

6. Run the following command to check whether you have the permission for executing the install.sh script:
