When enabled, the metadata calculation is triggered automatically by some actions, and can also be invoked manually by others. Either way, the metadata produced is served to YUM clients.
RPM metadata is automatically calculated:
You can manually invoke RPM metadata calculation:
Metadata calculation cleans up RPM metadata that already existed as a result of manual deployment or import. This includes RPM metadata stored as SQLite database files.
To create an RPM local repository, select RPM as the Package Type when you create the repository.
To enable automatic RPM metadata calculation on a local YUM repository, in the YUMSettings section of the Basic settings screen, set Auto-calculate YUM Metadata.
YUM Metadata Folder Depth
Informs Artifactory under which level of directory to search for RPMs and save the
By default this value is 0 and refers to the repository's root folder. In this case, Artifactory searches the entire repository for RPMs and saves the
Using a different depth is useful in cases where generating metadata for a repository separates its artifacts by name, version and architecture. This will allow you to create multiple RPM repositories under the same Artifactory RPM repository.
YUM Group File Names
A comma-separated list of YUM group files associated with your RPM packages.

Auto-calculate YUM Metadata
|When set, YUM metadata calculation is automatically triggered by the actions described above.|
Artifactory invokes the actual calculation only after a certain "quiet period", so the creation of metadata normally occurs only 1-2 minutes after the calculation was triggered.
Artifactory remote repositories support RPMs out-of-the-box, and there is no need for any special configuration needed in order to work with RPMs in a remote repository.
All you need to do is point your YUM client at the remote repository, and you are ready to use YUM with Artifactory.
To define a remote repository to proxy an YUM remote repository, follow the steps below:
targetCentos.repofile and paste the following configuration into it:
[targetCentos] name=targetCentos baseurl=http://localhost:8081/artifactory/targetCentos/ enabled=1 gpgcheck=0
A Virtual Repository defined in Artifactory aggregates packages from both local and remote repositories.
This allows you to access both locally hosted RPM packages and remote proxied RPM repositories from a single URL defined for the virtual repository.
To define a virtual YUM repository, create a virtual repository, set the Package Type to be RPM, and select the underlying local and remote RPM repositories to include in the Basic settings tab.
To allow deploying packages to this repository, set the Default Deployment Repository.
Artifactory supports using a GPG key to sign RPM metadata for authentication by the YUM client.
To generate a pair of GPG keys and upload them to Artifactory, please refer to GPG Signing.
Once you have configured your local machine to install RPM packages from your YUM local repository, you may also deploy RPM packages to the same repository using the UI or using the REST API.
Through the REST API you also have the option to deploy by checksum or deploying from an archive.
For example, to deploy an RPM package into a repository called
rpm-local you could use the following:
curl -u<USERNAME>:<PASSWORD> -XPUT http://localhost:8080/artifactory/rpm-local/<PATH_TO_METADATA_ROOT> -T <TARGET_FILE_PATH>
where PATH_TO_METADATA_ROOT specifies the path from the repository root to the deploy folder.
A YUM group is a set of RPM packages collected together for a specific purpose. For example, you might collect a set of "Development Tools” together as a YUM group.
A group is specified by adding a group XML file to same directory as the RPM packages included in it. The group file contains the metadata of the group including pointers to all the RPM files that make up the group.
Artifactory supports attaching a YUM Group file to the YUM calculation essentially mimicking the createrepo -g command.
A group file can also be created by running the following command:
sudo yum-groups-manager -n "My Group" --id=mygroup --save=mygroups.xml --mandatory yum glibc rpm
The process of attaching YUM group metadata to a local repository is simple:
.gzfile and deploy it next to the deployed group XML file.
.gzfile) to the
The following table lists some useful YUM group commands:
|Install the YUM group. The group must be deployed to the root of the YUM local repository.|
|Remove the RPM group|
Update the RPM group. The group must be deployed to the root of the YUM local repository.
|List the RPM packages within the group.|
|List the YUM groups|
YUM group properties can be set in the
/etc/yum.config file as follows:
|overwrite_groups||0 or 1|
Determines YUM's behavior if two or more repositories offer package groups with the same name.
If set to 1 then the group packages of the last matching repository will be used.
If set to 0 then the groups from all matching repositories will be merged together as one large group.
|groupremove_leaf_only||0 or 1|
Determines YUM's behavior when the groupremove command is run.
If set to 0 (default) then all packages in the group will be removed.
If set to 1 then only those packages in the group that aren't required by another package will be removed.
|enable_group_conditionals||0 or 1|
Determines whether YUM will allow the use of conditionals packages.
If set to 0 then conditionals are not allowed
If set to 1 (default) package conditionals are allowed.
|group_package_types||optional, default, mandatory||Tells YUM which type of packages in groups will be installed when |
If your organization uses a proxy server as an intermediary for Internet access, specify the
proxy settings in
/etc/yum.conf. If the proxy server also requires authentication, you also need to specify the
proxy=<proxy server url> proxy_username=<user> proxy_password=pass
If you use the yum plugin (
yum-rhn-plugin) to access the ULN, specify the
httpProxy settings in
/etc/sysconfig/rhn/up2date. In addition, If the proxy server requires authentication, you also need to specify the
proxyPassword settings as shown below.
enableProxy=1 httpProxy=<proxy server url> enableProxyAuth=1 proxyUser=<user> proxyPassword=<password>
YUM supports SSL from version 3.2.27.
To secure a repository with SSL, execute the following steps:
Define your protected repository in a
.repo file as follows:
[protected] name = SSL protected repository baseurl=<secure repo url> enabled=1 gpgcheck=1 gpgKey=<URL to public key> sslverify=1 sslclientcert=<path to .cert file> sslclientkey=<path to .key file>
gpgkey is a URL pointing to the ASCII-armored GPG key file for the repository . This option is used if YUM needs a public key to verify a package and the required key has not been imported into the RPM database.
If this option is set, YUM will automatically import the key from the specific URL. You will be prompted before the key is installed unless the assumeyes option is set.
You can use and reference the following built-in variables in
yum commands and in all YUM configuration files (i.e.
/etc/yum.conf and all
.repo files in the

You can view all the metadata that annotates an RPM by choosing it in Artifactory's tree browser and selecting the RPM Info tab:
The corresponding RPM metadata fields are automatically added as properties of an RPM artifact in YUM repositories accessed through Artifactory:
Properties can be used for searching and other functions. For more details please refer to Properties.
