scp免密拷贝

scp免密拷贝

（1.）在A机器生成秘钥

ssh-keygen -t rsa -P ""

(2.) 拷贝A机器公钥到B机器

scp /root/.ssh/id_rsa.pub root@IP_B:/root

(3.) 登录B机器,拷贝id_rsa_pub内容到.ssh目录下的authorized_keys文件中

cat id_rsa.pub >> .ssh/authorized_keys

(4.) 测试

ssh root@IP_B或
scp test.txt root@IP_B：/home/

(5.)设置权限

# 设置authorized_keys的权限
chmod 600 ~/.ssh/authorized_keys 
# 设置.ssh目录权限
chmod 700 -R ~/.ssh

（6.）修改sshd_config文件

vi /etc/ssh/sshd_config
Port 22
PermitRootLogin yes
PubkeyAuthentication yes
PasswordAuthentication no

（1.）安装sshpass

# ubuntu16.04执行:
sudo apt-get install sshpass

yum -y install gcc
tar xvzf sshpass-1.05.tar.gz
cd sshpass-1.05.tar.gz
./configure
