Preparations
Before performing operations in this section, familiarize yourself with the following information:
HA Installation Path
Default HA installation path:
- Atlas 500 AI edge station: /opt/middleware/ha/
- Other products (Atlas 500 Pro AI edge server): If you do not specify the installation path, the HA software is installed in the current path by default.
Paths for HA Configuration Files
- $(ha_install_path)/ha/module/hacom/conf/hacom.xml
- $(ha_install_path)/ha/module/haarb/conf/haarb.xml
- $(ha_install_path)/ha/module/hasync/conf/hasync.xml
- $(ha_install_path)/ha/local/hacom/conf/hacom_local.xml
$(ha_install_path) is the HA installation path. Replace it with the actual path.
- Modify all configuration parameters through the IES or FD WebUI instead of directly on the background. It is recommended that background maintenance commands only be used to perform query operations.
- After parameters are configured on the WebUI, you can run the cat or vi command on the background to check whether the preceding configuration is the same as the WebUI configuration.
HA Startup
It is recommended that you start and stop the HA using the FD or IES WebUI.
- Before starting the HA, ensure that the HA program is not running.
If the HA program is running, run the stopping script. The path for storing the stopping script is $(ha_install_path)/ha/module/hacom/script/stop_ha.sh.
- The path for storing the HA startup script is $(ha_install_path)/ha/module/hacom/script/start_ha.sh.
