5.6.2 Adding an OpenSearch Service

The script to add or delete the service uses the following arguments:

• -h or --help

  Show the help message and exit.

• --add

  An OpenSearch service will be added.

• --delete

  The OpenSearch service will be removed.

• --install_base_dir BASE_DIR

  Enter the base directory (BASE_DIR) where you installed the OSK DPK.

To add OpenSearch as a service:

1. Open a terminal window, running as root.

2. Change directory to OSK_INSTALL/setup:

   cd OSK_INSTALL/setup

3. Run this command to add the service:

   ./psft-os-service.sh --add --install_base_dir BASE_DIR
                  

4. Use this command to verify that the service was added.

   The output of the following ps command must show a running OpenSearch process:

   ps -ef | grep opensearch

5. Use this systemctl command to check if a service is started for OpenSearch:

   systemctl status opensearch

   This should give an output with the status “active (running),” as shown in bold font in this sample:

   opensearch.service - OpenSearch
      Loaded: loaded (/etc/systemd/system/opensearch.service; enabled; vendor preset: disabled)
      Active: active (running) since Tue 2020-09-01 22:24:38 PDT; 12s ago
