in general, i don’t recommend deleting the access nor error logs as they can helpful for troubleshooting issues. If they are several GB in size for some reason, then i suppose a case can be made to delete those files for some immediate free space.

Instead, I usually recommend using logrotate to keep the logs under control. A general tutorial on using logrotate for Apache is at this link

thank you, another question, when update/upgrade system i’ll need delete old packeges for free space? and how i can do it securly?

for red hat and centos systems, you could execute yum clean all, although my personal experience is that the local yum cache directory isn’t usually that big.

ok thank you however i am on ubuntu
