利用ansible书写playbook在华为云上批量配置管理工具自动化安装ceph集群

ansible、playbook、华为云、ceph

首先在华为云上购买搭建ceph集群所需云主机：

然后购买ceph所需存储磁盘

将购买的磁盘挂载到用来搭建ceph的云主机上

在跳板机上安装ansible

查看ansible版本，检验ansible是否安装成功

配置主机分组

测试结果

书写playbook文件内容如下：

 ---
 #将yum文件同步到各个节点
 - hosts: ceph
   remote_user: root
   tasks:
     - copy:
         src: /etc/yum.repos.d/ceph.repo
         dest: /etc/yum.repos.d/ceph.repo
     - shell: yum clean all
 #给ceph-0001主机安装ceph-deploy，创建工作目录，初始化配置文件

     - shell: 'chdir=/root/ceph-cluster ceph osd pool create cephfs_metadata 128'
     - shell: 'chdir=/root/ceph-cluster ceph fs new myfs1 cephfs_metadata cephfs_data'

playbook具体执行过程如下：

前往ceph-0001管理主机上验证：集群已搭建成功
