Preparing the configuration file for CentOS

The patch downloader utility for CentOS uses the configuration file that includes the following details:

• Definition of a proxy server (if one is used)
• Temporary directory on the server that is used by the utility during download
• Filter definitions

The utility downloads the metadata and payloads for CentOS based on the information specified in the configuration file.

To prepare the configuration file

Do the following:

1. Log in to the CentOS system.
2. Edit the sample XML configuration file (sample-rpmlinux-downloader.config) for use as the configuration file.

3. (Optional) Add the proxy server information using the following XML tags:

4. Add download information using the following XML tags:

5. Modify filters in the <subscription> tag. These filters define patches that are included for download.

   Example of a filter

   <filter type="channel" os-type="CENTOS" download-method="REPOSYNC" is-parent="true">
                <name>CentOs (v. 7 for 64-bit x86_64)</name>
                <os>CENTOS7</os>
                <arch>x86_64</arch>
        <child-channels>
           <name>CentOs-Base-7-x64</name>
           <name>CentOs-Updates-7-x64</name>
            <name>CentOs-7-x64</name>
          </child-channels>
   </filter>
   <filter download-method="REPOSYNC" os-type="CENTOS">
           <name>CentOs-Base-7-x64</name>
          <os>CENTOS7</os>
         <arch>x86_64</arch>
         <label>CentOs-Base-7-x64</label>
         <url>http://mirror.centos.org/centos/7/os/x86_64/</url>
   </filter>
   <filter download-method="REPOSYNC" os-type="CENTOS">
           <name>CentOs-7-x64</name>
          <os>CENTOS7</os>
         <arch>x86_64</arch>
         <label>CentOs-7-x64</label>
         <url>http://mirror.centos.org/centos/7/x86_64/</url>
   </filter>

6. Save the file.

   The following file shows some sample data and parameter descriptions (sample-rpmlinux-downloader.config):
