Subject: Some Juju issues when we take deploy tests, Chinese user
Dear Jorge Castro:
We are the Juju user from China. As we finished the deployment of CORD
in a box, which mainly use juju to control the final step to deploy MAAS and
openstack. We got a lot of problems, and to understand how Juju works, we have
done some local test in VM. There are some new questions occurs, hope get your
help.
We use juju 1.25 version on Ubuntu 14.04, cloud is local LXC
1. We completely install a MySQL database, and connect it with one web
driver. But when we add another one, it failed. So the question is that, did
one deployed MySQL unit support for multi-web to use?
2. When we install the mediawiki unit, there shows an error as below:
/var/lib/juju/agents/unit-mediawiki-0/charm/hooks/config-changed:
application-version-set: not found
We cannot find that path /var/lib/juju/agents/ in our VM, did it
download from Internet or change the filepath to others?
3. Besides, there is a misunderstanding error:
2017-10-20 02:58:51 WARNING juju.cmd.jujud machine.go:938 determining kvm
support: INFO: Your CPU does not support KVM extensions
KVM acceleration can NOT be used: exit status 1 no kvm containers possible
We use LXC container to install this, but it shows the information that
need KVM support, we still confuse with that, hopes you can give some advice
or solution.
4. Which path is the JujuCharm installed or downloaded , we have found one
path, named charmcache
But it just was a zip file, is that a temp directory or not? And how can we
find the runtime directory of Charm?
5. We have already read all the docs from jujucharms.com, but we do not
have a global understanding for juju and JujuCharm. Could you provide some Docs
which have some details or the abstract architecture for Juju? With that docs
,we could have a deeply understand and fix error easily.
Thanks for reading these questions, we sincerely hope your suggestions.
And best wishes for you!
