RPM based systems like RedHat, Fedora or CentOS often have the system configured for automatic updates. ������ rpm ��� �ý���ó��, ����� �Ǵ� centos ���� �ý����� �ڵ� ������ Ʈ�� �����մϴ�. This ensures that your software is always upto date. ��� ������ ����Ʈ����� �׻� �ִ� ��¥�մϴ�. However sometimes there are software you don't want to update via yum update like for example �׷��� ���δ��� ����Ʈ��� ������ Ʈ�� ���� �ְ��� �� ������ Ʈ������ �������� ���� �� RSSOwl rssowl . �մϴ�. RSSOwl, for example, currently has a broken rpm distribution in extras repository. rssowl, ���� ���, ����� ����Ʈ�� ������ �丮�� ���� ���� rpm �����մϴ�. Standard yum update will update the correct version directly downloaded from site and break it. ǥ�� ���� �ùٸ� ������ ���� ������ Ʈ�� ������ Ʈ���� �ٿ�ε� ����Ʈ �� �޽� �ð����ֽ��ϴ�. So you would want to prevent it from being updated. �׷��� ������ Ʈ�Ǵ� ���ϵ��� �;��մϴ�. For such scenarios there is a simple procedure for you to follows: �̷��� �ó������� ������ �����ִٴ� ������ ������ ���� :

1. First you should install yum yum-versionlock plugin: ù ��°�� ��ġ�ؾ� �� �� - versionlock �÷��� ���ӽ� :
yum -y install yum-versionlock . �ְ��� �� - �׸��� ��ġ�ϴ� �ְ��� �� - versionlock�մϴ�.

2. Open /etc/yum/pluginconf.d/versionlock.conf and set enabled = 1 ; save it. ���� / ��� / �ְ��� �� / pluginconf.d / versionlock.conf �� ���� Ȱ��ȭ = 1; �����մϴ�.

3. Create /etc/yum/pluginconf.d/versionlock.list and add the packages (along with version information as shown below) you want to exclude, one per line. ����� / ��� / �ְ��� �� / pluginconf.d / versionlock.list�� �߰��մϴ� ��Ű�� (�Ʒ� �׸�ó�� ���� ������ �Բ�)�� �������� �� �ٿ��մϴ�. For example I added a single line: rssowl-1.2.1-0.1 to exclude rssowl from ever being updated again by yum. ���� ��� �߰��ߴµ�, �ϳ��� ���� : rssowl - 1.2.1 - 0.1�� �����Ͽ� �ٽ� ������ Ʈ�Ǵ� ���� rssowl���� �ְ��� ��.

Note: You can run rpm -qa to get list of all installed packages along with their version information. ��� ���� : rpm - ǰ�� ������ ������ ���ֽ��ϴ� ��ġ�� ��� ��Ű�� ����� �������� �׵��� ���� ������ �Բ��մϴ�. grep it for your required packages. grep �װͿ� �ʿ��� ��Ű�����մϴ�.

You are done! ����� ������!
