I am trying to add instance to my innodb cluster. I turned off my firewall on both hosts (local vms).
This is the output of the cluster.addInstance('root#innodb-2:3306'); command:
ERROR: Unable to start Group Replication for instance 'innodb-2:3306'.
The MySQL error_log contains the following messages:

What version of MySQL and MySQL Shell are you using?
This seems like a connectivity issue, please ensure the allowlist is set if needed: https://dev.mysql.com/doc/mysql-shell/8.0/en/mysql-innodb-cluster-securing.html#create-allowlist-servers

But when I open any page in frontend then it shows

I installed Openstack in Ubuntu and started it using the ./start.sh command. When I try to login the dashboard, I get the error below about not being able to connect to Neuron:
ConnectionFailed at /project/
Connection to neutron failed: HTTPConnectionPool(host='192.168.204.173', port=9696): Max retries exceeded with url: /networking/v2.0/extensions (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f7efde4f460>: Failed to establish a new connection: [Errno 111] Connection refused'))
How do I fix this?
I'm currently using R version 3.6.1 and I'm trying to update it to R/4.2. I tried following instructions here and here. But everytime i try sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu focal-cran40/, I'm getting this error
Failed to connect to Mir: Failed to connect to server socket: No such file or directory
Unable to init server: Could not connect: Connection refused
Failed to connect to Mir: Failed to connect to server socket: No such file or directory
Unable to init server: Could not connect: Connection refused
How do I resolve this ?
I can't use httpd and nova-api at the same time.
when I used httpd service.The nova-api is dead(or inactive).
#systemctl restart openstack-nova-api
OUTPUT:
Job for openstack-nova-api.service failed because the control process exited
with error code. See "systemctl status openstack-nova-api.service" and
"journalctl -xe" for details.
I checked out the log,I get the error as follows.
LOG:ERROR nova.wsgi [-] Could not bind to 0.0.0.0:8774: error: [Errno 98] Address already in use.
CRITICAL nova [-] Unhandled error: error: [Errno 98] Address already in use.
And then,I try to find which process have used the port8774.
#netstat -tunlp | grep 8774
OUTPUT:
tcp 0 0 0.0.0.0:8774 0.0.0.0:* LISTEN 61690/httpd
When I #systemctl stop httpd->#systemctl restart nova-api->#systemctl restart http. I get a similiar mistake(I use RDO to install openstack-train version on centos 7).
they can't exist together
I have 2 ubuntu node (controller and compute) that i installed openstack, module by module.
but i can not create any instance.
in nova compute logs show this error:
ERROR nova.compute.manager [req-42d9d648-b39f-4214-9e5e-b8fb8799c10e 91704884e43f48fcbd156b8d7429fc3e 5e055db0a5464dc1997ab0f456792271 - default default] Instance failed network setup after 1 attempt(s): keystoneauth1.exceptions.connection.ConnectFailure: Unable to establish connection to http://localhost:9696/v2.0/networks?id=163f0b54-e337-40ac-81af-958c24ceeb7f: HTTPConnectionPool(host='localhost', port=9696): Max retries exceeded with url: /v2.0/networks?id=163f0b54-e337-40ac-81af-958c24ceeb7f (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f4ce476a820>: Failed to establish a new connection: [Errno 111] ECONNREFUSED')
