無需密碼的ssh

　　我在倆太機器上建立了等效性用戶，但是用等效性用戶訪問對方的時候 還需要密碼，為什麼啊？ 我的配置如下： .cat /etc/hosts #add by wangry 20051226 192.168.10.71 db1 192.168.10.73 db3 192.168.100.71 db1-priv 192.168.100.73 db3-priv 192.168.10.171 db1-vip 192.168.10.173 db3-vip 在db1上： mkdir ~/.ssh chmod 755 ~/.ssh /usr/bin/ssh-keygen -t rsa /usr/bin/ssh-keygen -t dsa cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys ssh Oracle@db3 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys ssh oracle@db3 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys 在db3上： mkdir ~/.ssh chmod 755 ~/.ssh /usr/bin/ssh-keygen -t rsa /usr/bin/ssh-keygen -t dsa cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys ssh oracle@db1 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys ssh oracle@db1 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys 測試： ssh db3 date ： [oracle@db1 ~]$ ssh db3 date 就不會出現 oracle@db3's passWord: （居然還要密碼）
