主機(jī)間無(wú)需密碼基于ssh通信-創(chuàng)新互聯(lián)
node1:172.16.58.1
node2:172.16.58.3
node1--> node2
首先在node1生成秘鑰
執(zhí)行命令ssh-keygen -P '' 詢問(wèn)保存路徑直接回車默認(rèn)即可， 后面提示私鑰保存為/root/.ssh/id_rsa 公鑰保存為/root/.ssh/id_rsa.pub |
[root@node1 ~]# ssh-keygen -P '' Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: dc:62:ba:81:ac:dd:d9:93:fa:b4:9b:21:8d:e7:98:8c root@node1.magedu.com The key's randomart p_w_picpath is: +--[ RSA 2048]----+ | | | | | | | . . | | S . | | . . = . | | o = =. | | o + %o+ | | .

把秘鑰傳給node2主機(jī)
ssh-copy-id -i .ssh/id_rsa.pub root@172.16.58.3 |
[root@node1 ~]# ssh-copy-id -i .ssh/id_rsa.pubroot@172.16.58.3 The authenticity of host '172.16.58.3 (172.16.58.3)' can'tbe established. RSA key fingerprint isdb:f8:11:fa:7d:30:95:44:1b:eb:ea:89:ee:fa:a1:27. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '172.16.58.3' (RSA) to the listof known hosts. root@172.16.58.3's password: Now try logging into the machine, with "ssh'root@172.16.58.3'", and check in: .ssh/authorized_keys to make sure we haven't added extra keys thatyou weren't expecting. |
