Https://docs.openstack.org/mitaka/zh_CN/install-guide-ubuntu/keystone-install.html

In the [database] section, configure database access:

[database]

...

Connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone

Controller should be changed to ip, otherwise the database will not be connected.

Configure the Apache HTTP server

Edit the ``/ etc/apache2/ apache2.conf`` file to configure the ``ServerName`` option for the control node:

ServerName controller

Controller will be changed to ip

Configure the Linuxbridge Agent Q

The Linuxbridge agent establishes the layer-2 virtual network for the instance and handles the security group rules.

Edit the ``/ etc/neutron/plugins/ml2/linuxbridge_ agent.ini`` file and complete the following:

In the ``[linux_bridge]`` section, correspond the public virtual network to the public physical network interface:

[linux_bridge]

Physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME

Change PROVIDER_INTERFACE_NAME to the actual network port name of the machine, such as eth0

Su-s / bin/sh-c "neutron-db-manage-- config-file / etc/neutron/neutron.conf\

>-- config-file / etc/neutron/plugins/ml2/ml2_conf.ini upgrade head "neutron

Sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) Cannot add a NOT NULL column with default value NULL [SQL: u'ALTER TABLE address_scopes ADD COLUMN ip_version INTEGER NOT NULL']

The reason for the error is that the original connection field in the neutron configuration file (/ etc/neutron/neutron.conf) is not deleted, which causes the newly assigned connection to be overwritten by the original one, and the original default still uses sqlite3....

Dashboard input default/admin/huawei, login authentication failed, check apach error.log, user admin login failed. Check the dashboard configuration file and there is a problem with one configuration:

OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3.0"% OPENSTACK_HOST

The correct ones should be:

OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3"% OPENSTACK_HOST

The hard disk was added, but the creation still failed because the filter field in / etc/lvm/lvm.conf did not add sdc to the accept.

If you specify key_name, an error will be reported:

Can be created without specifying a key_name

The community version comes with the Horizon plug-in for manila, and the M version does not have the Horizon plug-in for manila by default, so you can't see the operation of manila on Dashboard.

Https://github.com/openstack/manila-ui

Install git first

Apt-get install git

Download the code for horizon and manila-ui from github

Git clone https://github.com/openstack/horizon

Git clone https://github.com/openstack/manila-ui

Install gcc

Apt-get install gcc

Install python-dev

Sudo apt-get install python-dev

Install python-pip

Apt-get install python-pip

Cd horizon

Python tools/install_venv.py

After logging in to dashboard, you will receive an error. Apach log:

RuntimeError: Unable to create a new session key. It is likely that the cache is unavailab

Solution:

Vi / etc/openstack-dashboard/local_settings.py

SESSION_ENGINE = 'django.contrib.sessions.backends.cache' changed to SESSION_ENGINE =' django.contrib.sessions.backends.file'

If you are prompted that pip is not installed and apt-get install python-pip cannot be installed, please refer to http://www.linuxdiyf.com/linux/19248.html.

Manila is not included in Horizon in the OpenStack Mitaka distribution, and you need to install the additional plug-in manila-ui to display the Share menu in Horizon.

Install Manila UI View list: http://tarballs.openstack.org/manila-ui/

Pip install 'http://tarballs.openstack.org/manila-ui/manila-ui-stable-mitaka.tar.gz'
