openstack报错解决三

启动Nova时出错

linux-ffun:~ # nova service-list

Traceback (most recent call last):

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

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
