Operating Systems Linux Red Hat yum is not installed on all servers. Why? Post 302664515 by Perderabo on Friday 29th of June 2012 05:04:17 PM

We do not install yum on servers. We have a tested and approved build. We want that build and only that build installed on our servers. And we want all servers to have the same build. There is no repository available to our servers and without a repository yum is mostly useless. We do install rpm (the program). And once in a while we are forced to install a new rpm on all of the servers.

We have a RedHat 5 Server build, a RedHat 6 Server Build, and so on. We have just finished upgrading everything to RedHat 6. Once RedHat 7 hits the streets, we will test it and develop a standard build for RedHat 7. And then we will go around and update all of our servers again.

Some of these systems are on isolated networks. Some are in scif's. Most are behind firewall on our general internal network. 6 are on the Internet as DNS and NTP servers.

I agree with the general philosophy of this. I would install yum anyway. I do fight for more of the OS to be installed with each update. We have no telnet client installed! I don't like telnet, but the client is useful for troubleshooting. This is my current fight. However yum is pretty far down on the list.

Why are you guys so freaked out over the loss of yum?

NAME
yum verify plugin SYNOPSIS
yum [options] verify [package ...] DESCRIPTION
This plugin extends yum with some commands that give verification information on the installed system, much like rpm -V. You can change how the verification is done and which files it applies to. added yum commands are: * verify * verify-rpm * verify-all all of which take the same arguments as the list yum command, obviously you can only verify packages that are installed on the system. verify Is the generic verification command, and is intended to give the most useful output. It removes all false matches due to multilib and ignores changes to configuration files by default. verify-rpm Is meant to be 100% compatible with rpm -V output, and any differences should be considered as bugs. verify-all Is used to list all the differences, including some that rpm itself will ignore. GENERAL OPTIONS
These are the options added to yum that are available in the verify commands. They are: --verify-filenames This option is used to limit the filenames that the packages will perform verification. --verify-configuration-files This option is only useful in the generic verify command, and will enable/disable verification of files that are tagged as configu- ration files. EXAMPLES
To do the same as rpm -Va, use: yum verify-rpm To verify the packages starting with the name yum, use: yum verify 'yum*' To verify the binaries that are in a bin directory, use: yum verify --verify-filenames='*bin/*' To verify all include files, Eg. for multilib problems, use: yum verify-all --verify-filenames='/usr/include/*' SEE ALSO
yum (8) yum.conf (5) the verify.conf file in /etc/yum/plugins.d AUTHORS
James Antill <james.antill@redhat.com>. BUGS
Currently yum-verify does not do verify-script checking or dependency checking, only file checking. Should you find any other bugs, you should first consult the FAQ section on http://yum.baseurl.org/wiki/Faq and if unsuccessful in finding a resolution contact the mailing list: yum-devel@lists.baseurl.org. To file a bug use http://bugzilla.redhat.com for Fedora/RHEL/Centos related bugs and http://yum.baseurl.org/report for all other bugs. James Antill 01 March 2008 yum-verify(1)
