本文把openstack部署的所有命令整理成一个完整的脚本，一个脚本解决所有问题。 一般部署分三步：1，安装openstack包；2，修改配置文件；3，运行这个脚本。 mydeploy.py import os import commands status, CONTROLLER_HOSTNAME = commands.getstatusoutput('hostname') ADMIN_PASS='123456' MYSQL_PASS='123456' GLANCE_PASS = '123456' NOVA_PASS = '123456' NEUTRON_PASS = '123456' CINDER_PASS = '123456' KEYSTONE_DBPASS = '123456' GLANCE_DBPASS = '123456' NOVAAPI_DBPASS = '123456' NOVA_DBPASS = '123456' NEUTRON_DBPASS = '123456' CINDER_DBPASS = '123456' dbopt = { "keystone": [{"sysuser": "keystone", "dbname": "keystone", "dbpasswd": KEYSTONE_DBPASS, "dbsync": "keystone-manage db_sync"}], "glance": [{"sysuser": "glance", "dbname": "glance", "dbpasswd": GLANCE_DBPASS, "dbsync": "glance-manage db_sync"}], "nova": [ {"sysuser": "nova", "dbname": "nova_api", "dbpasswd": NOVAAPI_DBPASS, "dbsync": "nova-manage api_db sync"}, {"sysuser": "nova", "dbname": "nova", "dbpasswd": NOVA_DBPASS, "dbsync": "nova-manage db sync"} ], "neutron": [{"sysuser": "neutron", "dbname": "neutron", "dbpasswd": NEUTRON_DBPASS, "dbsync": "neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head"}], "cinder": [{"sysuser": "cinder", "dbname": "cinder", "dbpasswd": CINDER_DBPASS, "dbsync": "cinder-manage db sync"}] } serviceopt ={ "glance": [{"name":"glance", "type":"image", "description":"OpenStack Image", "http":"http://%s:9292" % CONTROLLER_HOSTNAME}], "nova": [{"name":"nova", "type":"compute", "description":"OpenStack Compute", "http":"http://%s:8774/v2.1/%%\(tenant_id\)s" % CONTROLLER_HOSTNAME}], "neutron":[{"name":"neutron", "type":"network", "description":"OpenStack Networking", "http":"http://%s:9696" % CONTROLLER_HOSTNAME}], "cinder": [ {"name":"cinder", "type":"volume", "description":"OpenStack Block Storage", "http":"http://%s:8776/v1/%%\(tenant_id\)s" % CONTROLLER_HOSTNAME}, {"name":"cinderv2", "type":"volumev2", "description":"OpenStack Block Storage", "http":"http://%s:8776/v2/%%\(tenant_id\)s" % CONTROLLER_HOSTNAME} ] } admin_env ={ "OS_USERNAME": "admin", "OS_PASSWORD": ADMIN_PASS, "OS_PROJECT_NAME": "admin", "OS_USER_DOMAIN_NAME": "Default", "OS_PROJECT_DOMAIN_NAME": "Default", "OS_AUTH_URL": "http://%s:35357/v3" % CONTROLLER_HOSTNAME, "OS_IDENTITY_API_VERSION": "3", "OS_IMAGE_API_VERSION": "2" } def exec_cmd(cmd): print "==>: " + cmd status, output = commands.getstatusoutput(cmd) if status != 0: raise Exception("[%s] \nCommand exec error: %s" % (cmd, output)) def create_db(dbs): for db in dbs: try: sql = "DROP DATABASE %s;
