把你的本地主機用戶的ssh公匙文件復制到遠程主機用戶的~/.ssh/authorized_keys文件中,假設本地主機linux(10.1.1.1),遠程主機linux(10.1.1.2)
一,在linux100主機裡的用戶
運行
#ssh-keygen -t rsa
結果如下
Generating public/private rsa key pair.
Enter file in which to save the key (/home/.username/ssh/id_rsa):#回車
Enter passphrase (empty for no passphrase):#回車
Enter same passphrase again:#回車
Your identification has been saved in /home/.username /.ssh/id_rsa.
Your public key has been saved in /home/.username /.ssh/id_rsa.pub.
The key fingerprint is:
38:25:c1:4d:5d:d3:89:bb:46:67:bf:52:af:c3:17:0c username@localhost
Generating RSA keys:
Key generation complete.
會在用戶目錄~/.ssh/產生兩個文件,id_rsa,id_rsa.pub
二,把linux(10.1.1.1)主機上的id_rsa.pub文件拷貝到linux(10.1.1.2)主機的root用戶主目錄下的.ssh目錄下,並且改名為authorized_keys
即:
/root/.ssh/authorized_keys
這樣在linux100主機上使用scp命令復制文件到linux(10.1.1.2)上將不提示輸入密碼了,直接復制了。反之亦然!
三,復制文件或目錄命令:
復制文件:
(1)將本地文件拷貝到遠程
scp 文件名 [email protected]:遠程路徑
(2)從遠程將文件拷回本地
scp [email protected]:文件名 本地路徑
復制目錄:
(1)將本地目錄拷貝到遠程
scp -r 目錄名 [email protected]:遠程路徑
(2)從遠程將目錄拷回本地
scp -r [email protected]:目錄名 本地路徑。
