Hello folks,

I tested rqlite via docker distribution and it works nice. Then I tried to launch 3 fedora nodes in VMWare and built the cluster. I have an error when I enter the command "rqlite" :

ERR! Get "http://127.0.0.1:4001//status": dial tcp 127.0.0.1:4001: connect: connection refused

I guess i've done something stupid or forgot to do something but what ?

You need to tell the CLI where to find a node, as per the manual.


  -H, --host[=127.0.0.1]
      rqlited host address

  -p, --port[=4001]
      rqlited host port

Actually, I run the command from the node CLI, sorry i did not mention. But thanks a lot, your answer lead me to my dumbness :)

I affected the nodes a bridged IP on local network and rqlite -H 10.0.4.x is working perfectly.

TY

When you set up clusters with rqlite, when you reboot the servers, the cluster doesn't get up by itself and I get this error you got. I am using the following commands while removing the cluster.

Where do you think I went wrong? Can you post the commands you used while removing the cluster?

./rqlited -node-id 1 -http-addr 10.10.10.88:4001 -raft-addr 10.10.10.88:4002 ~/node

./rqlited -node-id 2 -http-addr 10.10.10.89:4001 -raft-addr 10.10.10.89:4002 -join http://10.10.10.88:4001 ~/node

./rqlited -node-id 3 -http-addr 10.10.10.90:4001 -raft-addr 10.10.10.90:4002 -join http://10.10.10.88:4001 ~/node

Restarting a cluster absolutely works. It is tested here:


If you're getting an error connecting to the cluster it's not because rqlite can't do a simple restart, something else is going on.

Restarting a cluster where a quorum, or more, of nodes (in your case a quorum is 2 nodes) Raft IP addresses change will not start correctly, however. This is because the nodes have no way of finding each other at their new network addresses. If you must change a quorum of nodes' address, only change one address at a time, or use the recovery process.

No, you didn't understand me. I'm setting up an rqlite clsuter by following the instructions on the rqlite github page and entering the commands I just mentioned in my answer. However, the commands I entered work directly in the terminal. It does not run as a service or in the background. Therefore, when the terminal is closed, the command starting with ./rqlited stops. Why is rqlite not running as a service? How do you make it run in the background?

There are many ways to run rqlite -- Docker, rkt, as a service, within a VM etc. The specific way to run rqlite is left to the end-user (like yourself). If you want to run it as a service, then you need to write the service config file that best suits your needs.
