SSH驗證問題

whd

我的兩臺redhat  4   做RAC
以oracle用戶登錄，分別在兩臺機器上作(red1 red2)


mkdir ~/.ssh
chmod 700 ~/.ssh
ssh-keygen -t rsa
ssh-keygen -t dsa


然后在RAC1上執(zhí)行
red1-> cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
red1-> cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
red1-> ssh rac2 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
red1-> scp ~/.ssh/authorized_keys rac2:~/.ssh/authorized_keys

然后驗證
[oracle@Red1 .ssh]$ ls -l
total 24
-rw-r--r--  1 oracle oinstall 1644 Aug 13 11:32 authorized_keys
-rw-------  1 oracle oinstall  668 Aug 13 11:24 id_dsa
-rw-r--r--  1 oracle oinstall  601 Aug 13 11:24 id_dsa.pub
-rw-------  1 oracle oinstall  887 Aug 13 11:24 id_rsa
-rw-r--r--  1 oracle oinstall  221 Aug 13 11:24 id_rsa.pub
-rw-r--r--  1 oracle oinstall  454 Aug 13 11:36 known_hosts

[oracle@Red1 .ssh]$ ssh red1 date
oracle@red1's password:
Wed Aug 13 11:55:51 CST 2008
[oracle@Red1 .ssh]$ ssh red1 date
oracle@red1's password:
Wed Aug 13 11:55:56 CST 2008

[[oracle@Red1 .ssh]$ ssh red2 date
oracle@red2's password:
Wed Aug 13 11:59:40 CST 2008
[[oracle@Red1 .ssh]$ ssh red2 date
oracle@red2's password:
Wed Aug 13 11:59:40 CST 2008

為啥還是要提示我輸入密碼呢，我的第二臺機器是vmware copy過來，oracle 用戶設置都一樣的，ping red red-priv等都成功
為何就是不能實現(xiàn)免密碼呢，各位幫我看看呢

liaosnet

是把red1 上的id_rsa.pub的輸入>>　到red2上的~/.ssh/authorized_keys中
red2的到red1上.....不是本機..

whd

我的是把red1的輸入到本機，再把red2的也輸入到本機， 然后copy覆蓋到red2的機器上，保持同步的
我的步驟應該沒問題，是照文檔作的，估計那里設置不到或有權(quán)限什么的問題，大家?guī)椭�看看�?/td>

不行啊，也試過的

RSA實現(xiàn)無密碼認證：以Root身份登陸機器Ａ，執(zhí)行ssh-keygen –t rsa，一路回車，在Root/.ssh/下會生成２個文件id_rsa和id_rsa.pub，在機器Ｂ的Root目錄下建立目錄.ssh，在.ssh目錄下創(chuàng)建文件authorized_keys，把機器Ａ上id_rsa.pub文件里的內(nèi)容復制到authorized_keys里并保存，通過機器Ａ登陸機器Ｂ(ssh –p機器B端口號 [email=root@機器Ｂ]root@機器Ｂ[/email])，登陸成功后機器Ａ就會記錄下機器Ｂ的信息，以后從機器Ａ上登陸機器Ｂ就不用輸入密碼，實現(xiàn)了直接登陸。

whd

步驟我都很清楚了，就是還是不能實現(xiàn)不輸密碼登錄，每次連接都要密碼，郁悶死了/

難道AS4 up3的SSH有問題么

liaosnet

我這里沒有問題~~~~~ 你還是暫時不做dsa那個吧~~

你的sshd_config配了嗎？
如果配了貼出來看看。。
