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/1.5.1/ambari.repo

From the public repository:

http://public-repo-1.hortonworks.com/ambari/{$os}/1.x/updates/1.5.1/ambari.repo

Edit the ambari.repo file using the Ambari repository Base URL and the HDP-UTILS 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.

Table 1.13. Base URLs for a Local Repository
Repository	URL
Ambari Base URL	`http://{web-server}/ambari/{$os}/1.x/updates/1.5.1`
HDP-UTILS Base URL	`http://{web-server}/hdp/HDP-UTILS-{$version}/repos/{$os}`

If this an Ambari updates release, disable the GA repository definition. Also disable the HDP-UTILS repository definition for the version not being used for your stack. In the example below, GA is disabled and HDP_UTILS 1.1.0.16 is disabled. We have replaced the Base URLs for Ambari and HDP_UTILS 1.1.0.17.

/etc/zypp/repos.d
```
Edit the /etc/yum/pluginconf.d/priorities.conf file to add the following:
