A few time i already reinstall firewalld but seem not running. The error log did not thrown any error.
CODE
[root@localhost firewalld]# systemctl enable firewalld
[root@localhost firewalld]# systemctl restart firewalld
[root@localhost firewalld]# systemctl status firewalld

first try restart the system

then check if module disabled
sysctl -a | grep modules_disabled
if the value is 1 change to 0
you can change in /etc/sysctl.conf

after changing please restart the system

Usually in case like this:
1. tail and follow (-f) the log files

2. on a separate terminal, restart the services

3. On the window with the "live" log files running... see whats error or warning that appears.

I tried to give you some example commands... but the forums disallow it. But its pretty standard way of doing debugging/diagnostic... a simple web search will give u plenty of examples.

Have you disabled any iptables, ip6tables, ebtables and ipset services?

FYI I've never used firewalld, just basing this from the official docs https://firewalld.org/documentation/howto/e...-firewalld.html

Just found the issue. It's latest kernel. When booting using previous kernel, firewalld can run.

Somehow kernel not properly installed. Manually install kernel fix the issue.
