Linux設置ssh免密登陸配置

集羣

• node1 node2 node3

具體配置- 指定node1操做

• 生成祕鑰對

  ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
  複製代碼

• 追加本機公鑰到追到指定機器的 .ssh/authorized_keys 裏

  ssh-copy-id -i ~/.ssh/id_dsa.pub root@node1
  ssh-copy-id -i ~/.ssh/id_dsa.pub root@node2
  ssh-copy-id -i ~/.ssh/id_dsa.pub root@node3
  複製代碼

• 兩兩節點相互免密須要在每一個節點執行上述操做
