Starting Transformer Manually

When you install Transformer from a tarball, use the command prompt to manually start Transformer from the $TRANSFORMER_DIST directory, the location where you extracted the tarball and the base Transformer runtime directory.

When you start Transformer, Transformer runs as the user account logged into the command prompt. You can alternatively impersonate another user account when you run the command.

Use one of the following commands from the $TRANSFORMER_DIST directory to start Transformer manually.
- To run Transformer as the system user account logged into the command prompt, use:
```
bin/streamsets transformer 
```
- To run Transformer in the background as the system user account logged into the command prompt, use:
```
nohup bin/streamsets transformer &
```
- To run Transformer as another system user account, use:
```
sudo -u <user> bin/streamsets transformer
```
To access the Transformer UI, enter the following URL in the address bar of your browser:
```
http://<hostname>:19630/
```
If you enabled HTTPS for Transformer, use the HTTPS protocol and the secure port number in the URL, for example:
```
https://<hostname>:19636/
```
If you changed the default port number in the Transformer configuration properties, use that number instead.
The log in method depends on the that you use:
- When using Control Hub authentication, you may need to log into your Control Hub organization.
- When using LDAP authentication, you may need to log into your LDAP server.
- When using file-based authentication, you can use the following credentials to log in: admin / admin.
  If you created a custom login, feel free to use it.
