準備兩臺主機

????192.168.191.133? ?192.168.191.121

先在133主機上生成密鑰信息

[root@zabbix?~]#?ssh-keygen??-t?rsa?-P?''?-f?~/.ssh/id_rsa Generating?public/private?rsa?key?pair. 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: 6f:0f:05:55:26:31:88:13:b7:99:aa:27:4b:d5:10:96?root@zabbix The?key's?randomart?image?is: +--[?RSA?2048]----+ |????????++..=oo??| |???????.Eo.=?+???| |????????..=??????| |?????????+?.?????| |????????S?.?.????| |???????o?.?.?????| |??????+?.?+??????| |?????.?+?.?o?????| |??????.?????.????| +-----------------+

? ? ?2.生成驗證文件:authorized_key

[root@es?.ssh]#?cat?id_rsa.pub??>>?authorized_keys? [root@es?.ssh]#?ll total?16 -rw-------?1?root?root??389?Apr?25?05:33?authorized_keys -rw-------?1?root?root?1675?Apr?24?21:52?id_rsa -rw-r--r--?1?root?root??389?Apr?24?21:52?id_rsa.pub -rw-r--r--?1?root?root??531?Apr?25?05:26?known_hosts

? ? ? 3.拷貝密鑰對和認證文件到121上

???[root@es?.ssh]#scp??id_rsa*??root@192.168.191.121/root/.ssh[root@es?.ssh]#scp??authorized_keys??root@192.168.191.121/root/.ssh
