[ClusterLabs] WebSite_start_0 on node2 'error' (1): call=6, status='complete', exitreason='Failed to access httpd status page.'

[Jason Long]

Hello,
I used "Clusters from Scratch" to configuration two nodes. I got below error:

# pcs status
Cluster name: mycluster
Cluster Summary:
  * Stack: corosync
  * Current DC: node1 (version 2.0.5-10.fc33-ba59be7122) - partition with quorum

  * Last change:  Sun Mar 21 15:29:38 2021 by root via cibadmin on node1
  * 2 nodes configured
  * 2 resource instances configured

  * Online: [ node1 node2 ]

I have some questions:

1- In "Chapter 6. Add Apache HTTP Server as a Cluster Service", an important note said:
"Do not enable the httpd service. Services that are intended to be managed via the cluster software should never be managed by the OS. It is often useful, however, to manually start the service, verify that it works, then stop it again, before adding it to the cluster. This allows you to resolve any non-cluster-related problems before continuing. Since this is a simple example, we’ll skip that step here."

If the Apache service is not enabled they how can I connect to it via below command:

# wget -O - http://localhost/server-status
--2021-03-21 15:38:39--  http://localhost/server-status
Resolving localhost (localhost)... 127.0.0.1, ::1
Connecting to localhost (localhost)|127.0.0.1|:80... failed: Connection timed out.
Connecting to localhost (localhost)|::1|:80... failed: Network is unreachable.



2- Below commands must be run on both nodes or just one node?

# pcs resource create ClusterIP ocf:heartbeat:IPaddr2 ip="IP_That_Never_Used_In_The_Network" cidr_netmask=32 op monitor interval=30s

# pcs resource create WebSite ocf:heartbeat:apache configfile=/etc/httpd/conf/httpd.conf statusurl="http://localhost/server-status" op monitor interval=20s


3- Why "* WebSite    (ocf::heartbeat:apache):     Stopped" ?

Logs are:

Thank you.
