无需密码的ssh

我在俩太机器上建立了等效性用户，但是用等效性用户访问对方的时候 还需要密码，为什么啊？

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

测试：

ssh db3 date ：

[oracle@db1 ~]$ ssh db3 date

就不会出现

oracle@db3's password: （居然还要密码）
