rpm + how to identify if some rpm was removed or was not installed when installing the OS
Solution 1:
You can use yum history to find detailed information about a package installation, upgrade, or removal.
yum history list <package> will give a summary and yum history info <package> will give very detailed information.
For example:
[root@vmtest-centos7 ~]# yum history list htop
Loaded plugins: fastestmirror
ID | Command line | Date and time | Action(s) | Altered
-------------------------------------------------------------------------------
7 | -d 2 -y install tmux tra | 2019-12-04 03:33 | I, U | 49
history list
If more details are needed:
[root@vmtest-centos7 ~]# yum history info htop
Loaded plugins: fastestmirror
