把你的本地主机用户的ssh公匙文件复制到远程主机用户的~/.ssh/authorized_keys文件中,假设本地主机linux(10.1.1.1),远程主机linux(10.1.1.2)
一,在linux100主机里的用户
运行
#ssh-keygen -t rsa
结果如下
Generating public/private rsa key pair.
Enter file in which to save the key (/home/.username/ssh/id_rsa):#回车
Enter passphrase (empty for no passphrase):#回车
Enter same passphrase again:#回车
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 [email protected]
Generating RSA keys:
Key generation complete.
会在用户目录~/.ssh/产生两个文件,id_rsa,id_rsa.pub
二,把linux(10.1.1.1)主机上的id_rsa.pub文件拷贝到linux(10.1.1.2)主机的root用户主目录下的.ssh目录下,并且改名为authorized_keys
即:
/root/.ssh/authorized_keys
这样在linux100主机上使用scp命令复制文件到linux(10.1.1.2)上将不提示输入密码了,直接复制了。反之亦然!
三,复制文件或目录命令:
复制文件:
(1)将本地文件拷贝到远程
scp 文件名 [email protected]:远程路径
(2)从远程将文件拷回本地
scp [email protected]:文件名 本地路径
复制目录:
(1)将本地目录拷贝到远程
scp -r 目录名 [email protected]:远程路径
(2)从远程将目录拷回本地
scp -r [email protected]:目录名 本地路径。
