    14. [sudo] password for liu: 
    15. [liu@sv2 桌面]$ sudo passwd ceph-admin
    16. 更改用户 ceph-admin 的密码 。
    17. 新的 密码：
    18. 无效的密码： 密码是一个回文
    19. 重新输入新的 密码：
    20. passwd：所有的身份验证令牌已经成功更新。
    21. [liu@sv2 桌面]$  echo "ceph-admin ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/ceph-admin

    39. [ceph-admin@nimbus ~]$ ssh-keygen
    40. Generating public/private rsa key pair.
    41. Enter file in which to save the key (/home/ceph-admin/.ssh/id_rsa): 
    42. Created directory '/home/ceph-admin/.ssh'.
    43. Enter passphrase (empty for no passphrase): 
    44. Enter same passphrase again: 
    45. Your identification has been saved in /home/ceph-admin/.ssh/id_rsa.
    46. Your public key has been saved in /home/ceph-admin/.ssh/id_rsa.pub.
    47. The key fingerprint is:
    48. 1c:82:1a:19:38:b3:d0:9f:79:d7:4b:56:08:2e:7a:04 ceph-admin@nimbus
    49. The key's randomart image is:
    51. #修改文件
    53. vi .ssh/config
    54. Host node1
    55.    Hostname node1
    56.    User {username}
    57. Host node2
    58.    Hostname node2
    59.    User {username}
    60. Host node3
    61.    Hostname node3
    62.    User {username}
    63. #修改权限，发送过去
    64. sudo chmod 600 config
    65. ssh-copy-id {username}@node2
    66. ssh-copy-id {username}@node3
    69. # 配置sudo不需要tty
    70. sed -i 's/Default requiretty/#Default requiretty/' /etc/sudoers
    71. 或者在某些发行版（如 CentOS ）上，执行 ceph-deploy 命令时，如果你的 Ceph 节点默认设置了 
    72. requiretty 那就会遇到报错。可以这样禁用此功能：执行 sudo visudo ，找到 Defaults requiretty 选项，
    73. 把它改为 Defaults:ceph !requiretty ，这样 ceph-deploy 就能用 ceph 用户登录并使用 sudo 了。
