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.

Prerequisite

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

yum history command syntax

The basic syntax is:

 
yum history
yum history command #ID
yum history [options]
history [info|list|packages-list|summary|addon-info|redo|undo|rollback|new]
 

Examples

First, verify that history has been configured for yum command.
# ls -l /var/lib/yum/history/
Sample outputs:

total 1036
drwxr-xr-x. 30 root root    4096 Dec  9 11:40 2012-11-08
-rw-------.  1 root root 1050624 Dec  9 11:40 history-2012-11-08.sqlite

List your history

Type the following command:
# yum history
OR
# yum history list
Sample outputs:

Where,

  1. ID - Transaction number.
  2. Login user - The name of the user whose login session was used to initiate a yum.
  3. Date and time - The date and time when a transaction was issued by yum.
  4. Action(s) - A list of actions that were performed during a transaction as follows:
    1. D or Downgrade - Package has been downgraded to an older version.
    2. E or Erase - Package has been removed.
    3. I or Install - New package has been installed.
    4. O or Obsoleting - Package has been marked as obsolete.
    5. R or Reinstall - Package has been reinstalled.
    6. U or Update - Package has been updated to a newer version.
  5. Altered — The number of packages that were affected by a yum, as follows:
    1. *lt; - Before the transaction finished, the rpmdb database was changed outside yum.
    2. > - After the transaction finished, the rpmdb database was changed outside yum.
    3. * - The transaction failed to finish.
    4. # - The transaction finished successfully, but yum returned a non-zero exit code.
    5. E - The transaction finished successfully, but an error or a warning was displayed.
    6. P - The transaction finished successfully, but problems already existed in the rpmdb database.
    7. s - The transaction finished successfully, but the --skip-broken command line option was used and certain packages were skipped.

To see all transactions, pass the add option as follows:
# yum history list all

You can list only one transactions or transactions in a given range:

history info

To find out what additional information is available for a certain transaction:
# yum history addon-info id
# 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 yum command man page for more information.
