SSH快速入門

ssh登錄

基本用法

遠程登錄服務器:

# user:用戶名  hostname:ip地址或域名
ssh user@hostname 
ssh user@hostname -p 22

服務器別名

修改~/.ssh/config檔案,登錄遠程服務器可以使用別名s1, s2，下文的s1和s2都是遠程服務器的別名，

Host s1
    HostName ***.***.***.***
    User zk
    Port 22
Host s2
    HostName ***.***.***.***
    User zk
    Port 22

ssh配置免密登錄

首先使用ssh-keygen創建密鑰，會在~/.ssh/目錄下多了兩個檔案.

• id_rsa : 私鑰
• id_rsa_pub :公鑰
  最后在本地服務器執行ssh-copy-id s1 ，其中s1是遠程服務器的別名，該條命令的原理是公鑰(id_rsa_pub)中的內容復制到遠程服務器的~/.ssh/authorized_keys中，從而實作免密登錄，

服務器之間上傳下載檔案

復制檔案

• 將source1, source2路徑下的檔案復制到destination中，
  scp source1 source2 destination
• `指定服務器的埠號
  scp -P 22 source1 source2 destination

復制檔案夾

• 加上 -r 引數
  scp -r ~/tmp s1:/test
