Lab 16.2 Cannot make Lode Balancer work

andreizimin

On step 3, when I restart and check the status of HAProxy Load Balancer, it returns status as "Failed"
What am I doing wrong? Thank you!

Here are the command and the output:

student@ha-proxy:~$ sudo systemctl status haproxy.service

Hi @andreizimin,

Without the code formatting tags it is difficult to say if your haproxy.cfg file is correct. Compare the /etc/haproxy/haproxy.cfg file from the ha-proxy server with the file with the same name found in the SOLUTIONS tarball, to ensure it is accurate.

You may try to uninstall the haproxy, then install it again. Prior to step 2, check the status of the haproxy.service, and confirm it is running. Then proceed with steps 2 and 3 again.

If the restart command does not work, try a service stopfollowed by a service start instead.

Regards,
-Chris
