一、多台机器挂载到磁盘
0、准备条件(前提安装好ansible)
[root@k8s-m-01 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.10.110 k8s-m-01 m1
192.168.10.111 k8s-n-01 n1
192.168.10.112 k8s-n-02 n2
[root@k8s-m-01 ~]# cat /etc/ansible/hosts
[k8s]
172.16.1.111 ansible_ssh_pass='123'
172.16.1.112 ansible_ssh_pass='123'
192.168.10.110 ansible_ssh_user=root ansible_ssh_port=22 ansible_ssh_pass='123'
1、创建目录
[root@k8s-m-01 ~]# ansible k8s -m shell -a 'mkdir -p /data'
[root@k8s-m-01 ~]# ansible k8s -m shell -a 'ls /data'
172.16.1.112 | CHANGED | rc=0 >>
172.16.1.111 | CHANGED | rc=0 >>
192.168.10.110 | CHANGED | rc=0 >>
2、格式化文件系统
[root@k8s-m-01 ~]# ansible k8s -m shell -a 'echo "y"| mkfs.ext4 /dev/sdb' (否则就是交互式的)
3、挂载
[root@k8s-m-01 ~]# ansible k8s -m shell -a 'mount /dev/sdb /data'
172.16.1.112 | CHANGED | rc=0 >>
172.16.1.111 | CHANGED | rc=0 >>
192.168.10.110 | CHANGED | rc=0 >>
4、加入开机挂载
[root@k8s-m-01 ~]# ansible k8s -m shell -a "echo '`blkid |grep /dev/sdb|awk '{print$2}'` /data ext4 defaults 0 1' >> /etc/fstab"
5、查看
[root@k8s-m-01 ~]# ansible k8s -m shell -a 'tail -1 /etc/fstab'
172.16.1.111 | CHANGED | rc=0 >>
UUID="X9QWvD-OWHE-lhTd-Gtxm-lGuX-3nSC-WhvBMN" /data ext4 defaults 0 1
172.16.1.112 | CHANGED | rc=0 >>
UUID="X9QSSD-OWHE-lhTd-Gtxm-lGuX-3nSC-WhvBMN" /data ext4 defaults 0 1
192.168.10.110 | CHANGED | rc=0 >>
UUID="X9QOvD-OWHE-lhTd-Gtxm-lGuX-3nSC-WhvBMN" /data ext4 defaults 0 1
