Create the logrotate configuration file.

cat >> /etc/logrotate.conf << EOF
# Begin of /etc/logrotate.conf

# Rotate log files weekly.
weekly

# Send mail to no one.
nomail

# If the log file is empty, it do not rotate it.
notifempty

# Number of backups that will be kept.
# This will keep the 2 newest backups only.
rotate 2

# Create new empty files after rotating the old ones
# This will create empty log files, with owner
# set to root, group set to root, and permissions 644.

# Compress the backups with gzip.
compress

# RPM packages drop log rotation info in this directory.
# Uncomment if you use RPM packages.
# include /etc/logrotate.d

# End of /etc/logrotate.conf

Add each of the log files in /var/log to /etc/logrotate.conf to be rotated if they exceed 100K in size:

for logfile in $(find /var/log/*.log -type f); do
  echo $logfile {>> /etc/logrotate.conf
  echo # If the log file is larger than 100kb, rotate it >> /etc/logrotate.conf
  echo  	size=100k >> /etc/logrotate.conf
  echo } >> /etc/logrotate.conf
  echo "">> /etc/logrotate.conf
done
