配置Oracle用户的ssh authorized keys

1. login HOST1 as oracle ,在～/.ssh/下生存公id_rsa.pub、私钥id_rsa

ssh-keygen -t rsa

2. login HOST2 as oracle ,在～/.ssh/下生存公id_rsa.pub、私钥id_rsa

3. on HOST1,copy 认证key到host2且生成authorized_keys 文件

scp id_rsa.pub HOST2:/~/.ssh/authorized_keys

4. on HOST2, 把本机的authorized key 合并到刚才拷贝过的keys中，并回copy一份给HOST1

cat id_rsa.pub >> ~/.ssh/authorized_keys

scp authorized_keys HOST1:~/.ssh/
