Logrotate Error Because Parent Directory has Insecure Permissions - I'm currently tidying up the existing logs where I take the original logs and rotate them to any folder I want, but there was a problem when I tried to manually simulate this simulation would be applied before the system automatically ran it.

Encountering errors in log rotation processes can be a common occurrence for system administrators, especially when dealing with permissions and configurations. In this article, we delve into a specific error message, "Logrotate Error Because Parent Directory has Insecure Permissions," that halted the expected functionality of the logrotate utility on a Linux RHEL 7 server.

Issue

The issue surfaced when attempting to manually simulate log rotation using the following command:

# /usr/sbin/logrotate -f -v -s /var/lib/logrotate/logrotate.status /etc/logrotate.conf

However, an error was raised, hindering the successful execution of log rotation:

# error: skipping "/usr/local/zend/var/log/access.log" because parent directory has insecure permissions (It's world writable or writable by group which is not "root") Set "su" directive in config file to tell logrotate which user/group should be used for rotation.
because parent directory has insecure permissions
because the parent directory has insecure permissions

Cause

The error message clearly indicated that the problem stemmed from insecure permissions within the parent directory. Specifically, the directory had permissions that were either world-writable or writable by a group other than "root." To address this issue, the solution was to set the "su" directive in the logrotate configuration file, specifying the user and group to be used for rotation.

As seen above the error output is clear because of "Permissions" and we have been advised to "Set su" or add privileges to the configuration we made earlier :

# cat /etc/logrotate.d/zend
/usr/local/zend/var/log/*.log {
    olddir /apps/data/KitsakeLog/daily/zend
        daily
        rotate 7
    missingok
    lastaction
        /etc/logrotate.d/scripts/zend-ownership.sh
    endscript
}

Resolution

To rectify the problem, adjustments were made to the logrotate configuration file located at /etc/logrotate.d/zend. By adding the su root root directive, permissions were explicitly defined, ensuring secure execution of log rotation operations.

Here I try to enter "su root root" in the zend log configuration :

# vi /etc/logrotate.d/zend
/usr/local/zend/var/log/*.log {
    su root root
    olddir /apps/data/KitsakeLog/daily/zend
        daily
        rotate 7
    missingok
    lastaction
        /etc/logrotate.d/scripts/zend-ownership.sh
    endscript
}

Trying

With the configuration amended, a manual simulation of the logrotate process was initiated:

# /usr/sbin/logrotate -f -v -s /var/lib/logrotate/logrotate.status /etc/logrotate.conf

The following image is the result of a correctly executed logrotate, which conforms to the parameters we configured in the previously set-up configuration file.
