mac无密登陆到linux

最近弄了台linux云服务器，然而每次登陆linux都好麻烦，所以倒腾了下ssh无密登陆。

linux：centos 6.5，自带ssh

mac：yosemite，自带ssh

 

步骤：

1. 创建key

?  .ssh ssh-keygen -t rsaGenerating public/private rsa key pair.Enter file in which to save the key (/Users/yinkw/.ssh/id_rsa):        <--直接回车Enter passphrase (empty for no passphrase):                            <--直接回车Enter same passphrase again: Your identification has been saved in /Users/yinkw/.ssh/id_rsa.Your public key has been saved in /Users/yinkw/.ssh/id_rsa.pub.The key fingerprint is:07:20:96:中间这一段藏起来:d1 yinkw@yinkw.localThe key‘s randomart image is:+--[ RSA 2048]----+|    ooooo=o+     ||   ...+o= + E    ||     . *.+ .     ||      . =.+      ||        S=..     ||         .o      ||                 ||                 ||                 |+-----------------+?  .ssh lltotal 16-rw-------  1 yinkw  staff   1.6K 10  6 12:11 id_rsa           <--私钥-rw-r--r--  1 yinkw  staff   399B 10  6 12:11 id_rsa.pub       <--公钥

2. 拷贝公钥到linux

?  .ssh scp id_rsa.pub root@19.29.～～:~/.sshroot@119.29.～～‘s password: id_rsa.pub                                                                                   100%  399     0.4KB/s   00:00

3. linux，公钥内容追加到authorized_keys

[root@centos]~/.ssh# ll总用量 4-rw-r--r-- 1 root root   0 9月  15 00:27 authorized_keys-rw-r--r-- 1 root root 399 10月  6 12:26 id_rsa.pub[root@centos]~/.ssh# cat id_rsa.pub >> authorized_keys

4. mac测试

?  ~ ssh root@119.29.～～                                                      Last login: Thu Oct  6 12:06:38 2016 from 101.106.～～

诶诶，这是怎么回事，没用重启sshd服务，却已经可以使用rsakey登陆了

 

5. linux关闭passwd登陆

/etc/ssh/sshd_config：

PermitEmptyPasswords no

关掉passwd登陆后自我感觉安全多了

 

--done--
