cloudstack delete zone

第一步:CloudStack数据库的重新初始化
  1)、停止CloudStack服务。service cloud-management stop.
  2)、到mysql里查询select uuid from storage_pool; 删除存储的SR。
  # mysql -u root -ptcloud
  mysql> use cloud;
  Database changed
  mysql> select uuid from storage_pool;
  +————————————–+
  | uuid |
  +————————————–+
  | 6550eb15-daed-363e-be38-7e76bcd973ec |
  | 7abfabe4-7081-3b1e-8ab3-4dcbc9633636 |
  | db8002d3-1c41-383c-bab3-a561b9583547 |
  +————————————–+
  3 rows in set (0.00 sec)
  3)、删除CloudStack数据库,drop database cloud; drop database cloud_usage;
  # mysql -u root -ptcloud
  Welcome to the MySQL monitor. Commands end with ; or \g.
  Your MySQL connection id is 11958
  Server version: 5.0.77 Source distribution
  Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the buffer.
  mysql> drop database cloud; drop database cloud_usage;
  4)、重新部署CloudStack数据库 cloudstack-setup-databases cloud:password@localhost –deploy-as=root:password
  # cloud-setup-databases cloud:password@localhost –deploy-as=root:password
  Testing specified deployment credentials on server localhost:3306
  Setting up user credentials in:
  -> /etc/cloud/management/db.properties … done.
  Applying file /usr/share/cloud/setup/create-database.sql to the database on server localhost:3306
  Applying file /usr/share/cloud/setup/create-schema.sql to the database on server localhost:3306
  Applying file /usr/share/cloud/setup/create-database-premium.sql to the database on server localhost:3306
  Applying file /usr/share/cloud/setup/create-schema-premium.sql to the database on server localhost:3306
  Applying file /usr/share/cloud/setup/server-setup.sql to the database on server localhost:3306
  Applying file /usr/share/cloud/setup/templates.sql to the database on server localhost:3306
  Applying file /usr/share/cloud/setup/create-index-fk.sql to the database on server localhost:3306
  
  5)、cloud-setup-management
  # cloud-setup-management
  Starting to configure ElasterStack Management Server:
  Configure sudoers …
  Configure Firewall …
  Configure CloudStack Management Server …
  ElasterStack Management Server setup is Done!
第二步:初始化主存储和二级存储
  1)、删除主存储和二级存储中的所有文件
第三步:准备二级存储
  1)、在管理节点上挂载二级储存NFS目录:/export/secondary。
  # mkdir -p /mnt/secondary
  # mount -t nfs 172.16.204.111:/export/secondary /mnt/secondary/
  2)、下载SystemVm文件
  3)、解压SystemVm文件
  #/usr/lib64/cloud/agent/scripts/storage/secondary/cloud-install-sys-tmplt -m /mnt/secondary -f systemvm.vhd.bz2 -h xenserver -F
  4)、完成以后,卸载二级储存
  #umount /mnt/secondary/
第四步:重新安装主机上的Hypervistor。
    如果要是不想重新安装主机上的Hypervistor,参考第一步的第2项,删除存储的Sr。
  =====================================================================================================
  在进行环境清理,然后重建环境需要注意的步骤

1. 管理节点

(1) 通过mysql客户端登陆mysql服务器,删除cloud,cloud_usage,cloudbridge库

(2) 重新通过命令初始化如上库

必要的时候(希望完全清理的时候),挂载二级存储,一级存储,删除所有文件,然后重新挂载二级存储,导入系统VM模板

2. 代理节点

(1) 针对KVM主机, virsh pool-destroy 原有的存储池 (一级存储以及二级存储)

(2) 针对VCenter,卸载原有挂载的存储(一级存储以及二级存储),需事先删除所有的主机跟模板文件。



然后再重新通过按照上面的安装步骤进行环境的重新搭建,基本不会出现由于旧环境的残留数据引起的奇怪问题。
