Centos7 ssh

step 1

computer A remote access computer B
computer A 192.168.1.16
computer B 192.168.1.19

run following command install ssh server on computer A and B
yum install openssh-server

run following command on computer A to access computer B
ssh -CX username@192.168.1.19

step 2

ssh-keygen 产生公钥与私钥对.
ssh-copy-id 将本机的公钥复制到远程机器的authorized_keys文件中，ssh-copy-id也能让你有到远程机器的home, ~./ssh , 和 ~/.ssh/authorized_keys的权利

第一步:在本地机器上使用ssh-keygen产生公钥私钥对

$ ssh-keygen

第二步:用ssh-copy-id将公钥复制到远程机器中

$ ssh-copy-id -i .ssh/id_rsa.pub 用户名字@192.168.x.xxx

注意: ssh-copy-id 将key写到远程机器的 ~/ .ssh/authorized_key.文件中
第三步: 登录到远程机器不用输入密码

$  ssh 用户名字@192.168.x.xxx

sshfs name@server:/path/to/folder /path/to/mount/point
yum install sshfs
