For Linux, log files are located under the /var/log directory and its subdirectories. Within this directory there are several log files with different names and which record different types of info. Some examples include, but are not limited to:

/var/log/message
Contains global system messages, including the messages that are logged during system startup. Includes mail, cron, daemon, kern, auth, etc.

/var/log/auth.log
Authenication logs

/var/log/kern.log
Kernel logs

/var/log/cron.log
Crond logs
