Openstack之數據庫同步調試

    直接用Openstack官方的源代碼安裝，到了同步數據庫一步了，用: 

[root@xgtest scripts]# 

/usr/lib/python2.6/site-packages/nova-2012.2-py2.6.egg/EGG-INFO/scripts

[root@xgtest scripts]# python nova-manage  db sync 

報了個提醒：

[root@xgtest scripts]# cat /var/log/nova/nova-manager.log 

2012-08-27 15:08:35 CRITICAL nova [-] /usr/lib/python2.6/site-packages/nova-2012.2-py2.6.egg/nova/db/sqlalchemy/migrate_repo

數據庫沒有同步成功

直接去看看這裏面的文件： /usr/lib/python2.6/site-packages/nova-2012.2-py2.6.egg/nova/db/sqlalchemy/migrate_repo

執行：[root@xgtest migrate_repo]# python manage.py version

發現當前文件夾少了文件： migrate.cfg

去安裝好的環境裏面看看：

[root@node74 ~]# find /usr/ -name migrate.cfg

/usr/lib/python2.6/site-packages/glance-2012.1-py2.6.egg/glance/registry/db/migrate_repo/migrate.cfg

/usr/lib/python2.6/site-packages/nova-2012.1-py2.6.egg/nova/db/sqlalchemy/migrate_repo/migrate.cfg

/usr/lib/python2.6/site-packages/keystone-2012.1-py2.6.egg/keystone/common/sql/migrate_repo/migrate.cfg

/usr/lib/python2.6/site-packages/migrate/versioning/templates/repository/pylons/migrate.cfg

/usr/lib/python2.6/site-packages/migrate/versioning/templates/repository/default/migrate.cfg

把對應文件scp過去：

/usr/lib/python2.6/site-packages/nova-2012.1-py2.6.egg/nova/db/sqlalchemy/migrate_repo/migrate.cfg

這個文件配置爲：

[root@xgtest migrate_repo]# cat migrate.cfg 

[db_settings]

# Used to identify which repository this database is versioned under.

# You can use the name of your project.

repository_id=nova

# The name of the database table used to track the schema version.

# This name shouldn't already be used by your project.

# If this is changed once a database is under version control, you'll need to 

# change the table name in each database too. 

version_table=migrate_version

# When committing a change script, Migrate will attempt to generate the 

# sql for all supported databases; normally, if one of them fails - probably

# because you don't have that database installed - it is ignored and the 

# commit continues, perhaps ending successfully. 

# Databases in this list MUST compile successfully during a commit, or the 

# entire commit will fail. List the databases your application will actually 

# be using to ensure your updates to that database work properly.

# This must be a list; example: ['postgres','sqlite']

required_dbs=[]

從新執行：

[root@xgtest migrate_repo]# python manage.py version

115

[root@xgtest migrate_repo]# 

good,

繼續執行：

[root@xgtest scripts]# pwd

/usr/lib/python2.6/site-packages/nova-2012.2-py2.6.egg/EGG-INFO/scripts

[root@xgtest scripts]# 

[root@xgtest scripts]# 

[root@xgtest scripts]#  nova-manage    --logdir=/var/log/nova/ --logfile=/var/log/nova/nova-manager.log  --sql_connection=mysql://nova:nova@10.28.163.158/nova db sync

執行成功，找時間好好看看openstack數據庫操做部分。
