启动Nova时出错

linux-ffun:~ # nova service-list

Traceback (most recent call last):   File "/usr/bin/nova", line 6, in <module>     from novaclient.shell import main   File "/usr/lib/python2.7/site-packages/novaclient/shell.py", line 38, in <module>     import keyring   File "/usr/lib/python2.7/site-packages/keyring/__init__.py", line 12, in <module>     from .core import (set_keyring, get_keyring, set_password, get_password,   File "/usr/lib/python2.7/site-packages/keyring/core.py", line 158, in <module>     init_backend()   File "/usr/lib/python2.7/site-packages/keyring/core.py", line 58, in init_backend     set_keyring(load_config() or _get_best_keyring())   File "/usr/lib/python2.7/site-packages/keyring/core.py", line 66, in _get_best_keyring     keyrings = backend.get_all_keyring()   File "/usr/lib/python2.7/site-packages/keyring/util/__init__.py", line 24, in wrapper     func.always_returns = func(*args, **kwargs)   File "/usr/lib/python2.7/site-packages/keyring/backend.py", line 179, in get_all_keyring     _load_backends()   File "/usr/lib/python2.7/site-packages/keyring/backend.py", line 139, in _load_backends     list(map(_load_backend, backends))   File "/usr/lib/python2.7/site-packages/keyring/backend.py", line 124, in _load_backend     mod = importlib.import_module('.'+name, package)   File "/usr/lib64/python2.7/importlib/__init__.py", line 37, in import_module     __import__(name)   File "/usr/lib/python2.7/site-packages/keyring/backends/Gnome.py", line 6, in <module>     gi.require_version('GnomeKeyring', '1.0') NameError: name 'gi' is not defined

这里需要修改python源代码，将标红处注释掉。

linux-ffun:~ # vi /usr/lib/python2.7/site-packages/keyring/backends/Gnome.py

import os try:     from gi import Repository     if Repository.get_default().enumerate_versions('GnomeKeyring'):         #gi.require_version('GnomeKeyring', '1.0')         from gi.repository import GnomeKeyring except ImportError: 补充1：

openstack安装到这一步后，注释掉那行代码，再启动还是可能会报错，这个时候注意看nova.conf。这里面有个my_ip不能写死为hosts里配置的controller。必须写当前主机的ip地址，原因不明，注红处是修改后的。

linux-ffun:/etc/nova # vi nova.conf

[DEFAULT] verbose = True log_dir = /var/log/nova connection_type = libvirt compute_driver = libvirt.LibvirtDriver image_service = nova.image.glance.GlanceImageService volume_api_class = nova.volume.cinder.API auth_strategy = keystone network_api_class = nova.network.neutronv2.api.API bindir = /usr/bin state_path = /var/lib/nova lock_path = /run/nova service_neutron_metadata_proxy = True security_group_api = neutron rpc_backend = rabbit auth_strategy = keystone my_ip = 172.16.15.13 network_api_class = nova.network.neutronv2.api.API security_group_api = neutron linuxnet_interface_driver = nova.network.linux_net.NeutronLinuxBridgeInterfaceDriver firewall_driver = nova.virt.firewall.NoopFirewallDriver enabled_apis=osapi_compute,metadata verbose = True [cors] [cors.subdomain] [database] connection = mysql+pymysql://nova:NOVA_DBPASS@controller/nova [matchmaker_redis] [matchmaker_ring] [oslo_concurrency] lock_path = /var/run/nova [oslo_messaging_amqp]

补充2：ml2_conf.ini文件的flat_networks的值为oa

linux-ffun:/etc/neutron/plugins/ml2 # vi ml2_conf.ini

[ml2_type_flat]

flat_networks = oa

这个oa和接口设置有关。注意飘红处

linux-ffun:/etc/neutron/plugins/ml2 # vi linuxbridge_agent.ini

[linux_bridge] physical_interface_mappings = oa:eth1
