linux建立ssh信任關係
建立SSH信任 將A主機做為用戶端（發起SSH請求 ip:192.168.200.170） 將B主機作為伺服器端（接收ssh請求   ip:192.168.200.149） 以上以主動發起SSH登入請求的主機和接收請求的主機進行分類 <1>A主機產生公，私密金鑰認證            [root@buddytj-10 .ssh]# ssh-keygen -t rsa     #rsa演算法的認證Generating public/private rsa key pair. （以下一路斷行符號）Enter file in which to save the key (/root/.ssh/id_rsa):    /root/.ssh/id_rsa already exists.Overwrite (y/n)? y                      （因為我的認證已存在，覆蓋即可）Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. （私密金鑰）Your public key has been saved in /root/.ssh/id_rsa.pub. （公開金鑰）The key fingerprint is:c1:26:cc:88:2b:05:dd:c3:6b:1e:78:5d:da:9c:da:8a  認證就產生了   id_rsa （私密金鑰）|& id_rsa.pub （公開金鑰）  <2>將A主機產生的公開金鑰傳遞給B主機 [root@xyh .ssh]#scp id_rsa.pub  192.168.200.149：/root/.ssh/ 在B主機上將A的公開金鑰更名為[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！
