Jekins SSH Server(Use password authentication, or use a different key) 配置

環境：A爲jekins所在機器，B爲需要發佈應用的機器

B機器執行的操作

1. 生成rsa密鑰, 會讓輸入保存位置，這裏直接打回車，保存在/root/.ssh目錄(-P 後面跟的是私鑰密碼)

[root@tom /]# ssh-keygen -t rsa -P '123456'
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Created directory '/root/.ssh'.
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
d9:24:d6:fa:f4:ec:ba:3e:c0:40:bd:47:1a:ff:01:c2 root@tom
The key's randomart image is:
+--[ RSA 2048]----+

[root@tom /]# cd /root/.ssh/
[root@tom .ssh]# ll
total 8
-rw------- 1 root root 1743 Aug  7 19:25 id_rsa
-rw-r--r-- 1 root root  419 Aug  7 19:25 id_rsa.pub

2.  下面看一下jekins的SSH Server配置界面

注意下面要做的就是爲上面Username處的用戶配置公鑰，本例中，在機器B上新建一個用戶，用戶名爲jekins. 如果已有用戶直接將id_rsa.pub追加到已有用戶的authorized_keys文件中即可。

將公鑰導入authorized_keys文件，並修改文件權限：

[root@tom .ssh]# cat id_rsa.pub >> /home/jekins/.ssh/authorized_keys
[root@tom .ssh]# chmod 600 /home/jekins/.ssh/authorized_keys

 3. 配置 SSH Server

   查看剛纔生成的密鑰：

[root@tom .ssh]# cat id_rsa
-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: DES-EDE3-CBC,38ECA4066C46AC09

  填寫SSH Server配置界面,Passphrase/Password爲剛纔生成密鑰時的密碼：123456，key爲上面密鑰內容
