Starting and Logging Into the Upgraded Control Hub

Before you log into the upgraded Control Hub, use the following steps to start Control Hub.

Start the system Data Collector.
For a highly available production environment, start the load balancer for Control Hub.
Start each Control Hub instance from the command prompt, using the required command for your installation type:
- Tarball installation for a manual start
  Use the following command from the $DPM_HOME directory to start Control Hub so that it runs as the system user account logged into the command prompt:
```
bin/streamsets dpm
```
  Or, use the following command to start Control Hub and run it in the background:
```
nohup bin/streamsets dpm &
```
  Use the following command to start Control Hub so that it runs as another system user account:
```
sudo -u <user> bin/streamsets dpm
```
- Tarball or RPM installation for a service start
  Use the required command for your operating system to start Control Hub as a service:
  - For CentOS 6.x, Oracle Linux 6.x, Red Hat Enterprise Linux 6.x, or Ubuntu 14.04, use:
```
service dpm start
```
  - For CentOS 7.x, Oracle Linux 7.x - 8.x, or Red Hat Enterprise Linux 7.x - 8.x, use:
```
