Mac no secret login to Linux

Recently got a Linux cloud server, but every time landing Linux is good trouble, so daoteng the next SSH no secret landing.

Linux:centos 6.5, bring your own SSH

Mac:yosemite, bring your own SSH

Steps:

1. Create key

? .SSH Ssh-keygen-T rsagenerating Public/private RSA key pair. Enterfile inch whichTo save the key (/users/yinkw/.SSH/id_rsa): <--Direct Enter enter passphrase (empty forno passphrase): <--Direct Enter enter same passphrase Again:your identification has been saved inch/users/yinkw/.SSH/Id_rsa. Your public key has been savedinch/users/yinkw/.SSH/id_rsa.pub.The Key fingerprint is: -: -: the: This section of the middle is hidden.:d 1 [email protected]the key's Randomart image is:+--[RSA2048]----+|   ooooo=o+ | |     ... +o= + E | | .     *.+ .      || .        =.+      ||     S=.         ||                 . O | |                 ||                 || |+-----------------+? .SSHLltotal --RW-------1YINKW Staff1.6KTen  6  A: Oneid_rsa <--private key-rw-r--r--1YINKW Staff 399BTen  6  A: OneId_rsa.pub <--Public Key

2. Copy the public key to Linux

?  . SSH SCP id_rsa.pub [email protected]19.29.~~: ~/. SSH [email protected] 119.29. ~ ~ '  id_rsa.pub                                                                                     399     0. 4kb/s   :  XX

3. Linux, public key content appended to Authorized_keys

[Email protected]]~/. SSH  41 root root   0 September  :  authorized_ Keys1399 October  6:  Id_rsa.pub[[email Protected]]~/. SSH cat id_rsa.pub >> Authorized_keys

4. Mac Test

?  SSH [Email protected] 119.29. ~ ~ Login: Thu Oct                                                          6 : £101.106. ~ ~

Eh, what's going on, it's useless to restart the sshd service, but you can already use Rsakey to log in

5. Linux off passwd Login

/etc/ssh/sshd_config:

Permitemptypasswords No

I feel safer when I turn off the passwd landing.

--done--
