Sysadmin Connection refused after yum update

looks like it goes back to yum transaction id = 1

So firewalld was installed on your system via os default image. Centmin Mod doesn't install firewalld by default but if it detects it, it will stop/disable firewalld without removal. So probably what happened for you.

some packages depend on firewalld and blind removal might remove those packages accidentally too

and what firewalld depends on

Code (Text):

repoquery --requires --resolve firewalld    
iptables-services-0:1.4.21-17.el7.x86_64

python-firewall-0:0.4.3.2-8.1.el7_3.noarch
firewalld-filesystem-0:0.4.3.2-8.1.el7_3.noarch

Code (Text):

yum deplist firewalld -q

  dependency: systemd

So should be fine to leave as is

 

looks like good to just remove them if you want

Complete!

 

only need to do yum remove once for that and no extra packages seem to be removed so that's good

 

Are you using Centmin Mod LEMP stack ? this forum is for Centmin Mod LEMP stack support. I ask as Centmin Mod doesn't use firewalld but CSF Firewall so usually firewalld isn't active.

 

Unfortunately wouldn't be able to help you as Centmin Mod doesn't use firewalld. Might want to ask on CentOS 7 official forums CentOS - CentOS 7
