How to create limit size log make it rotates?

2

rsyslog will do it

 /etc/rsyslog.conf

# provides UDP syslog reception
module(load="imudp")
input(type="imudp" port="514")

# provides TCP syslog reception
module(load="imtcp")
input(type="imtcp" port="514")

# List of sub networks authorized to connect :
$AllowedSender UDP, 127.0.0.1, 192.168.9.0/24
$AllowedSender TCP, 127.0.0.1, 192.168.10.0/24

That config doesn’t limit log size or rotate the logs. To do that you need to combine rsyslog to “data filtrate” the logs and logrotate to control size and age of the logs.
