Hi list, I'm trying to install openstack ml2 neutron ml2 plugin devstack on 2 nodes with CentOS. Basically, I have followed http://devstack.org/guides/multinode-lab.html. That is really helpful. Things looks well on controller node. But, on the compute node, I get many issues. This is my local.conf on compute node: http://paste.openstack.org/show/82898/ After run "./stack.sh", I get: http://paste.openstack.org/show/82899/ So, I run "./rejoin-stack.sh". Three services has been started: 1$ q-agt 2$ n-cpu 3-$ c-vol But, neutron-agent and nova-compute is complains about "Unable to connect to AMQP server". And cinder-volume complains about "SQL connection failed" Because services on controller node works well, so I first thought it is caused by iptables. but after I run: sudo iptables -I INPUT 1 -p tcp --dport 5672 sudo iptables -I INPUT 1 -p tcp --dport 3306 on controller node. The issue is still there. Anyone know why this happened ?? Thanks. -chen -------------- next part -------------- An HTML attachment was scrubbed...
