HI,

I have tried to install CDF 2019.08 on RHEL 7.2, but encounter below issue:

2019-07-15T17:55:39 03:00 INFO : Configure and start the ETCD database ................................ [ FAILED ]
2019-07-15T17:57:55 03:00 FATAL : Failed to start ETCD database. Refer to /tmp/install.20190715175529.log file for detail information. If need, please contact system administrator or Micro Focus support.

Further checking the install log I can see:

2019-07-16T09:11:59.999086191 03:00 DEBUG exit_code: 0
2019-07-16T09:12:00.00521755 03:00 DEBUG exec_cmd # /opt/kubernetes/bin/etcdctl --cacert=/opt/kubernetes/ssl/ca.crt --cert /opt/kubernetes/ssl/server.crt --key /opt/kubernetes/ssl/server.k
ey --endpoints https://Hostname :4001 get / --prefix --keys-only=true
2019-07-16T09:12:00.00521755 03:00 DEBUG exit_code: 2

Manually running the command:

[root@Hostname etcd]# /opt/kubernetes/bin/etcdctl --cacert=/opt/kubernetes/ssl/ca.crt --cert /opt/kubernetes/ssl/server.crt --key /opt/kubernetes/ssl/server.key --endpoints https://Hostname :4001 get / --prefix --keys-only=true
Error: dial tcp 15.119.191.194:4001: getsockopt: connection refused

Checking for any process listening, I could not see etcd and port 4001:

etcd 58052 etcd 5u IPv4 302287 0t0 TCP localhost:2380 (LISTEN)
etcd 58052 etcd 6u IPv4 302288 0t0 TCP localhost:2379 (LISTEN)

It looks try to reach hostname:4001 port for certs, but same refused.

Firewall is disabled.

Thanks,

Yavor
