Hi, I'm running the same issue right know.
In my company we have a cloud platform and all nodes have internal Ips.
Nodes that belong to the same clusters see each other through a global IP
assignation in the platform, not through internal IP (because internal IP
depends on where the node is physically located).
I'm trying to install couchbase in a cluster of three nodes and I'm getting
the following issues:
Information:
- Cluster name: *couchbase-test*
- Node 1:
- Name: *couchbase-test-01*
- internal ip: *192.168.19.113*
- global ip: *10.70.168.112*
- namespace : *couchbase-test-01.xds.net*
- Node 2:
- Name: *couchbase-test-02*
- internal ip: *192.168.22.32*
- global ip: *10.70.169.234*
- namespace : *couchbase-test-02.xds.net*
- Node 3:
- Name: *couchbase-test-03*
- internal ip: *192.168.25.167*
- global ip: *10.70.169.252*
- namespace : *couchbase-test-03.xds.net*
So I installed couchbase server in the first node, but the only hostname
that didn't prompt me error were (*192.168.19.113 or 127.0.0.1*), if I put
the global IP or the namespace I got "Could not resolve the hostname:
nxdomain".
Then, I installed couchbase in node 2. However, when I try to configure it
to join to the cluster generated by the first Node putting *192.168.22.32 *in
the "hostname" and in "join cluster ip" *10.70.168.112 *I get this "
*Attention* - Failed to reach erlang port mapper at node "192.168.22.32".
Error: ehostunreach".
Here's an example of hosts file for Node 1:
127.0.0.1 localhost
169.254.169.254 instance-data
# The following lines are desirable for IPv6 capable hosts
*::1 ip6-localhost ip6-loopback*
*fe00::0 ip6-localnet*
*ff00::0 ip6-mcastprefix*
*ff02::1 ip6-allnodes*
*ff02::2 ip6-allrouters*
*ff02::3 ip6-allhosts*
*192.168.19.113 couchbase-test-01*
*10.70.169.234 couchbase-test-02.xds.net*
*10.70.169.252 couchbase-test-03.xds.net*
*10.70.168.112 couchbase-test-01.xds.net*
Could you guys help me?
Thanks in advance,
Adrián
