[yum] How to check when is an RPM installed/updated last time?

thomas2004ch · 03-25-2014, 03:03 AM

Hi,

I use the RedHat Linux. I use quite often the command 'yum' to install, update or upgrade the RPM packages. Sometimes I want to know when is a pachage installed or updated last time.

yum.log will record all of your update activities
OR
yum history

Hi,

see /var/log/yum.log*

YUM history and logs :

The "rpm last" command may also be useful :
$ rpm -qa --last | grep <name> (or part of package name)

Saving an install list with date/time, the latest install in line 1:
$ rpm -qa --last > last-packages.txt

Yes, I know the file /var/log/yum.log. But it seems it just contains the information from begin this year. I think this could be configured to contain longer log information. Right?

Did you check for rotated log files? Ie /var/log/yum.log* (as suggested earlier).

I think this command does nothing else than read in the file /var/log/yum.log, right?

Here is rotation for yum.log:

Code:

/var/log/yum.log {
    missingok
    notifempty
    size 30k
    yearly
    create 0600 root root
}

I think I have to increase the size from 30K to a larger size, right?

But if I even want to see the record from last January, should I take out the yearly and set 600 days for example?

I list the file size of /var/log.yum.log and it tells as follow:

Code:

# ll -h /var/log/yum.log
-rw------- 1 root root 48K Mar 21 11:24 /var/log/yum.log

One can see the size is not 30K but 48K. Why?

Because the logrotate is yearly

I think you'll find rpm reads the rpm db (/var/lib/rpm/ on Centos 6)

See post #10, @chrism01.

$ rpm -qa <-etc. option> : Uses the "rpm data base" (/var/lib/rpm/),
which means that also packages installed without using yum are listed.
I.e. packages installed with # rpm -Uvh <package.rpm>

Can someone answer my question in post #8 at the end?

Code:

man logrotate

You can't have two conditions. The last one, in this case "yearly", overrides. If you run logrotate with the "-d" flag you will see that it is using only the "yearly" test.

The most straightforward way to find the install/update date for a package is to run "rpm -qi {packagename}" and note the line that begins "Install Date:".
