5.2.4. Preparing The Ambari Repository Configuration File

Download the ambari.repo file from the mirror server you created in the preceding sections or from the public repository.
- From your mirror server:
```
http://{web-server}/ambari/{$os}/1.x/updates/1.6.1/ambari.repo
```
- From the public repository:
```
http://public-repo-1.hortonworks.com/ambari/{$os}/1.x/updates/1.6.1/ambari.repo
```

Edit the ambari.repo file using the Ambari repository Base URL obtained when setting up your local repository. Refer to step 3 in Setting Up a Local Repository having No Internet Access, or step 5 in Setting Up a Local Repository having Temporary Internet Access, if necessary.
