Once the core Semaphore components are installed they will need to be started before they can be used.
How to start Semaphore Studio
To start Semaphore Studio, simply start the Semaphore daemon by running:
systemctl start semaphore
Note: Starting the Semaphore daemon will not only start Semaphore Studio, but also Knowledge Model Management (KMM), and Document Analyzer (DA).
If for some reason, you need to start Semaphore Studio ONLY, then simply start the Semaphore Studio daemon by running:
systemctl start semaphore-studio
On installation, the Semaphore daemon is set to start itself on machine startup, however, if this has been disabled you can re-enable it by running the following command:
systemctl enable semaphore
How to start Knowledge Model Management (KMM)
As mentioned, KMM is usually started when you start the Semaphore deamon. But if you need to start KMM ONLY, then simply start the KMM daemon by running:
systemctl start semaphore-kmm
How to start Document Analyzer (DA)
Similar to KMM, DA is also usually started when you start the Semaphore deamon. But if you need to start DA ONLY, then simply start the DA daemon by running:
systemctl start semaphore-da
How to start Classification Service (CS)
To start the CS daemon, simply run:
systemctl start semaphore-cs
On installation, the CS daemon is set to start itself on machine startup, however, if this has been disabled you can re-enable it by running the following command:
systemctl enable semaphore-cs
How to start Semantic Enhancement Service (SES)
To start the SES daemon, simply run:
systemctl start semaphore-ses
On installation, SES daemon is set to start itself on machine startup, however, if this has been disabled you can re-enable it by running the following command:
systemctl enable semaphore-ses
