Auto-start Services
Services in OpenPanel start only when they are actually needed, to avoid wasting resources.
Auto-start Services in OpenAdmin
Upon installing OpenPanel, only the following services are started:
- OpenAdmin – For managing the entire server and users.
- Docker – Needed for all other containerized services and user accounts.
- Database – MySQL database is created and initialized. This database holds Plans, Websites, Domains, and Users.
- Firewall – CSF or UFW are installed and started.
Other services are installed and started only when required.
| Service | Installed | Auto-start |
|---|---|---|
| OpenAdmin | YES | On installation |
| Docker | YES | On installation |
| Database | YES | On installation |
| ConfigServer Firewall | YES | On installation |
| Uncomplicated Firewall | NO | On installation |

Auto-start Services in OpenPanel
Using the /etc/entrypoint.sh for each user, Administrators define which services to auto-start when their container is started. The container is started after a user is created and on every Docker service restart.
Similar to OpenAdmin, services in OpenPanel also start only when they are needed. This allows for better resource management. An idle account will use around 15MB of RAM, while an account with domains, websites, and MySQL databases may use up to 1GB of RAM.
