CentOS / RHEL See Detailed History Of yum history Commands nixCraft Updated Tutorials/Posts

I would like to see detailed information on the history of yum transactions such as updates, deleted packages, and other information. How do I see history of yum commands on a CentOS Linux/ RHEL 6.x or 7.x based server? How do I undo or redo or rollback packages using yum command?

The yum command has history option on the latest version of CentOS / RHEL v6.x+. To database are normally found in /var/lib/yum/history/ directory. The history option was added at the the end of 2009 (or thereabouts) to yum command. The history command allows an admin to access detailed information on the history of yum transactions that have been run on a system. You can see what has happened in past transactions (assuming the history_record config. option is set). You can use various command line options to view what happened, undo/redo/rollback to act on that information and start a new history file. This page shows how to use yum history command to find out information about installed, updated, and removed packages.

Prerequisite: Find yum command version on a CentOS/RHEL

You need yum version 3.2.xx or CentOS/RHEL 6.x. Verify this with the following command:
# yum info yum | grep --color Version
Sample outputs from CentOS v6.5:

Version : 3.2.29

Here is output from the CentOS Linux box:

To find out what additional information is available for a certain transaction:

# yum history addon-info 24

To just get info on last transaction:
# yum history addon-info last

How do I undo / revert transactions?

Say, you deleted the nginx package using yum command:
# yum erase ngnix
Now, use yum history command to review the transaction history, the yum history command provides means to revert or repeat a selected transaction. To revert (undo) a transaction, type the following at a shell prompt as root:
# yum history undo id
To undo nginx erase action, type:
# yum history
# yum history package-list nginx

Sample outputs:

Loaded plugins: downloadonly, fastestmirror, security
ID | Action(s) | Package ------------------------------------------------------------------------------- 29 | Erase | nginx-1.4.4-1.el6.ngx.x86_64 28 | Install | nginx-1.4.4-1.el6.ngx.x86_64 EE
history package-list

To undo use ID # 29:
# yum history undo 29
Verify that nginx has been installed again:
# yum history package-list nginx

Loaded plugins: downloadonly, fastestmirror, security
ID | Action(s) | Package ------------------------------------------------------------------------------- 30 | Install | nginx-1.4.4-1.el6.ngx.x86_64 EE 29 | Erase | nginx-1.4.4-1.el6.ngx.x86_64 28 | Install | nginx-1.4.4-1.el6.ngx.x86_64 EE
history package-list

How do I redo / repeat transactions?

To repeat a particular transaction, run:
# yum history redo id

The yum history rollback option

The syntax is:
# yum history rollback id
The rollback command will undo all transactions up to the point of the specified transaction. For example, if you have 3 transactions, where package A; B and C where installed respectively. Then “yum history undo 1” will try to remove package A, “yum history redo 1” will try to install package A (if it is not still installed), and “yum history rollback 1” will try to remove packages B and C.

The yum new option

As described above, the yum command stores the transaction history in a single SQLite database file in /var/lib/yum/history/ directory. To start new transaction history, run the following command:
# yum history new
Verify with the following command:
# yum history
I strongly suggest that you read the yum command man page using the man command or this page for more information:
$ man yum
