Hello,

I got a similar issue and solved it by disabling IPv6 under main host so lxc containers could communicate through IPv4 and access to external world. I haven't yet understand the issue but it sounds like if the main host is IPv6 enabled, then system tries to communicat through IPv6 even though IPv4 addresses are the only one configured.
If anyone get an idea let me know.
If you think that needs a bug let Jake or me know (at least) as we get concerned with the issue
Thanks
Thierry

Hi Jake,

Thanks for the logs! However, I still can't find the reason this
should be happening just from those logs. Can you also send us the
unit logs from wordpress and mysql? A dump of "ifconfig -a" on each of
the machines should also be useful.

Regards,
Dimiter

Hi Jake,

Can you provide some more information: - your environments.yaml
file - machine-0.log, machine-1.log, and machine-2.log from
/var/log/juju/ on each machine Before sending these, please make a
quick check to remove any sensitive info from the files (e.g.
access/secret keys, password, etc.)

You can get the logs by using "juju ssh 0" (or 1 and 2 for the
other machines) to connect, run chown a+r
/var/log/juju/machine*.log, then log back out and use "juju scp
0:/var/log/juju/machine-0.log ~/" (again replace 0 with 1 or 2).

Thanks! Dimiter

Hi,

I am using juju 1.21.1-trusty-i386 and deploying to a manual
environment, and had a problem deploying wordpress following
the getting started page here [1].  When I tried to view
wordpress with a browser it gave me an "Error establishing a
database connection", and from a little bit of digging found
that wordpress was configured with an ipv6 address for the
mysql host.  Switching this manually to the ipv4 address
fixed the problem.

Assuming for a minute that wordpress doesn't support ipv6, is
there a way to avoid having it configured with an ipv6
address?  I see that unit-get private-address is returning
the ipv6 address for the mysql host, is that normal behavior?
On the mysql host machine log, I see this:

2015-02-27 14:56:59 INFO juju.worker.machiner machiner.go:94
setting addresses for machine-2 to ["local-machine:127.0.0.1"
  "public:9.114.192.29" "local-machine:::1"
"local-cloud:fd55:faaf:e1ab:38d:944a:7931:9b4c:c621"
"local-cloud:fd55:faaf:e1ab:38d:a8c0:f5da:7109:1e67"
"local-cloud:fd55:faaf:e1ab:38d:f816:3eff:fee2:f0fc"]

Thanks in advance for any advice, Jake Kugel
