As the up2date utility for RedHat automatic update has become
a paid service by
RedHat,
you may use the free apt-get utility instead.
APT-RPM is a port of Debian's apt tools to a RPM based distribution (Red Hat,
Conectiva, SuSE etc). apt-get is an advanced package management utility
front-end which allows you to easily perform package installation, upgrading and removal.
Dependencies are automatically handled, so if you try to install a package that needs
others to be installed, it will download all needed packages and install them.
More information on apt-get can be found at
http://apt.freshrpms.net/ or
http://apt-rpm.tuxfamily.org/.
Prior to updating your RedHat packages with apt-get, make sure to exclude
the following services from the apt-get configuration:
- postgresql, postgresql-server, postgresql-libs on CP and user postgresql boxes;
- apache and apache-related packages on H-Sphere CP, WEB and MAIL boxes;
- proftpd and related packages on H-Sphere WEB boxes;
- qmail, vpopmail, ezmlm and related packages on H-sphere MAIL boxes.
- bind and related packages on H-Sphere nameserver boxes.
To exclude packages, modify the corresponding part of your /etc/apt/apt.conf file, similar
to this:
// Completely ignore the following packages (not regexp)
// Ignore { };
Ignore { "bind-utils"; };
// Do not try to update the following packages
// Hold { };
Hold { "postgresql*"; "apache*"; "proftp*"; "qmail*"; "vpopmail*"; "ezmlm*"; "sendmail*"; "bind*"; };
If you have accidentally upgraded your RedHat without excluding these packages, you need to
downgrade bind and
downgrade PostgreSQL.
Also, prior to running apt-get, back up /etc/rsyncd.conf, and restore it after the update.
