linux建立ssh信任關系

建立SSH信任   將A主機做為客戶端(發起SSH請求 ip:192.168.200.170)   將B主機作為服務器端(接收ssh請求   ip:192.168.200.149)   以上以主動發起SSH登錄請求的主機和接收請求的主機進行分類   <1>A主機生成公,私鑰證書             [root@buddytj-10 .ssh]# ssh-keygen -t rsa     #rsa算法的證書 Generating public/private rsa key pair. (以下一路回車) Enter file in which to save the key (/root/.ssh/id_rsa):     /root/.ssh/id_rsa already exists. Overwrite (y/n)? y                      (因為我的證書已存在,覆蓋即可) Enter passphrase (empty for no passphrase):  Enter same passphrase again:  Your identification has been saved in /root/.ssh/id_rsa. (私鑰) Your public key has been saved in /root/.ssh/id_rsa.pub. (公鑰) The key fingerprint is: c1:26:cc:88:2b:05:dd:c3:6b:1e:78:5d:da:9c:da:8a    證書就生成了   id_rsa (私鑰)|& id_rsa.pub (公鑰)    <2>將A主機生成的公鑰傳遞給B主機  [root@xyh .ssh]#scp id_rsa.pub  192.168.200.149:/root/.ssh/   在B主機上將A的公鑰更名為 [root@xyh .ssh]#mv id_rsa.pub authorized_keys    <3>至此從A主機遠程SSH B主機的工作即告完成   呵呵,超簡單的!
