Using external metadb or engine, the hengshi script cannot control the status of external services. You can control it through parameters, skipping external component status checks during installation or upgrade.

./hs_install -p /opt/hengshi/ -e [all|metadb|engine] ## Use 'all' when using both external metadb and engine
