Call api /auth/user_token once every minute. After starting the server, the call is normal. Something goes wrong after a while.

First, run the command "mage check" to check . After that, take a look at the results. Then, review the output to understand what it shows.

skiffer-git commented 2 months ago

When the message "produced zero addresses" appears, you need to take action. At that point, run the command "mage check".

skiffer-git commented 2 months ago

How did you set it up? What changes did you make to the settings? Can you explain it step by step?

happy2wh666 commented 2 months ago

The mage check in the above content is executed after an error appears in the logs

Use a Docker-based Golang environment to compile and run the server.

services:
  openim:
    image: golang
    container_name: openim
    user: root
    privileged: true
    volumes:
      - "/openim:/openim"
    restart: always
    network_mode: "host"
    command: /openim/happy.sh

docker startup command

usm@/openim$ cat ./happy.sh
#!/bin/sh
cd /openim
bash bootstrap.sh
if [ ! -e skip_build ]
then
  mage
fi
touch skip_build
mage start
mage check
tail -f /dev/stdout
skiffer-git commented 2 months ago

I suggest you use the source code for the deployment.

skiffer-git commented 2 months ago

Can you tell me if the IP address 74.48.52.186 is a public one or just an internal network address?

happy2wh666 commented 2 months ago

I suggest you use the source code for the deployment.

The server is compiled from source code. Both the compilation and execution are done inside a Docker container with image “golang”.

Can you tell me if the IP address 74.48.52.186 is a public one or just an internal network address?

public, with linux firewall

skiffer-git commented 2 months ago

There's no need to use a public IP address. You can just stick with an internal IP address for this situation

happy2wh666 commented 2 months ago

Is this issue related to the internal IP or public IP? The point is that the server was running normally at the beginning, but the error occurred after a period of time. Restarting the server made it normal again, but then the error occurred again after some time.

skiffer-git commented 2 months ago

When you run into an issue, take a look at the data on etcd.

happy2wh666 commented 2 months ago

I keep running the follow command for a long time, during which it only outputs some PUT and DELETE.

I have no name!@host:/opt/bitnami/etcd$ etcdctl watch / --prefix

while read -r line; do
    echo "New key: $line"
done

PUT
/check_openim_component

DELETE
/check_openim_component

PUT
/check_openim_component

DELETE
/check_openim_component

...
...
...
skiffer-git commented 2 months ago

try to watch /openim

happy2wh666 commented 2 months ago

watch / --prefix has include watch /openim

happy2wh666 commented 2 months ago

I deployed the server and all other components like redis and etcd kafka on the same server, and the issue has not occurred again.

The issue may be caused by a communication problem between the server and other components that has not been resolved. For example, the server may not have properly reconnected after losing connection with Redis.
