How can we determine if keepalived is functioning properly?
To confirm if keepalived is functioning properly, you can perform the following steps:
- Check if the keepalived process is running. You can use the following command to verify if the process is present:
ps -ef | grep keepalived
If the process exists, it indicates that keepalived is running.
- The log file for Keepalived can be found at /var/log/keepalived.log.
tail -f /var/log/keepalived.log
If you see information about keepalived in the log, it means keepalived is running.
- Check the status of keepalived. You can use the following command to check the status of keepalived:
service keepalived status
If keepalived is running correctly, you should see a message like “keepalived is running.”
- Check if the virtual IP (VIP) is functioning properly. You can use the following command to verify if the VIP has been correctly assigned to a node by keepalived.
ip addr show | grep <VIP>
If the VIP is correctly assigned to a certain node, the IP address of that node should be displayed.
By performing the above steps, you should be able to determine if keepalived is working properly. If keepalived is not working as expected, you can verify the configuration file and refer to the log file for additional information to troubleshoot the issue.
