Hi, all

I mean how to configurate devstack localrc to use mysql and how to generate mysql db tables ? I can rewrite the lib/ceilometer's connection to use mysql url, but it doesn't generate mysql db tables, which results ceilometer-api fails to start.

Can anyone help me ? Thanks!

I was facing the same problem. For me it got resolved with change in FIXED_RANGE in local.conf and few changes in /etc/hosts file. Below is how my /etc/hosts looks like after changes

127.0.0.1 localhost hadoop

####127.0.1.1 hadoop

10.20.1.180 hadoop

The following lines are desirable for IPv6 capable hosts

::1 localhost ip6-localhost ip6-loopback

ff02::1 ip6-allnodes

ff02::2 ip6-allrouters

Currently, devstack doesn't support mysql as ceilometer backend, but for now, that is what I do :

1. enable ceilometer in localrc

enable_service ceilometer-acompute,ceilometer-acentral,ceilometer-collector,ceilometer-api

2. change the database connection in lib/ceilometer

iniset $CEILOMETER_CONF database connection mysql://root:rachel@localhost/ceilometer?charset=utf8

where rachel is mysql password for root.

3. change ceilometer/collector/service.py code

    $ git diff
    diff --git a/ceilometer/collector/service.py b/ceilometer/collector/service.py
    index 898e551..91b8c70 100644
    --- a/ceilometer/collector/service.py
    +++ b/ceilometer/collector/service.py
    @@ -112,6 +112,7 @@ class CollectorService(rpc_service.Service):
         def __init__(self, host, topic, manager=None):
             super(CollectorService, self).__init__(host, topic, manager)
             self.storage_conn = storage.get_connection(cfg.CONF)
    +        self.storage_conn.upgrade()

         def start(self):
             super(CollectorService, self).start()

then run ./stack.sh, it will generate mysql db tables during ceilometer-collector starts.

But now, devstack has support mysql as ceilometer backend, just set CEILOMETER_BACKEND=mysql in localrc

Hi Rain Guan, I tried with CEILOMETER_BACKEND=mysql option in localrc. But I am still getting errors in ceilometer-api saying ceilometer-api failed to start.
