Keepalived doesn't work on CentOS 8. #1891

Closed hack3rcon closed 3 years ago

hack3rcon commented 3 years ago

Hello, I used Keepalived tutorial to configure Keepalived on two CentOS web servers: Server 1: 192.168.56.7 Server 2: 192.168.56.9 Virtual IP: 192.168.56.110 And after it, I added below Firewalld rule:

# firewall-cmd --add-rich-rule='rule protocol value="vrrp" accept' --permanent
# firewall-cmd --reload

But I can't ping my Virtual IP address:

# ping 192.168.56.110
PING 192.168.56.110 (192.168.56.110) 56(84) bytes of data.
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted

And cURL doesn't show anything too: # curl -l 192.168.56.110 I used "ip addr show NIC" command and Virtual IP address is assigned to my NIC, but why it doesn't work?

Thank you.

@hack3rcon Unfortunately you haven't provided any of the necessary information to ascertain what is happening here.

You will need to provide:

  1. A copy of your keepalived configurations
  2. The output of keepalived -v
  3. What version of CentOS you are using (I have now read the subject and see that it is CentOS 8)
  4. The output of ip addr show
  5. The output of iptables -nvL and nft list ruleset
  6. The keepalived logs from the two servers
  7. Which server you are running the ping command on
