远程登录服务器

ssh user@hostname
1

• user:用户名
• hostname：IP地址或域名

第一次登陆会显示信息：

The authenticity of host ‘123.57.47.211 (123.57.47.211)’ can’t be established.
ECDSA key fingerprint is SHA256:iy237yysfCe013/l+kpDGfEG9xxHxm0dnxnAbJTPpG8.
Are you sure you want to continue connecting (yes/no/[fingerprint])?

我们直接输入yes，远程服务器的信息就会被记录在~/.ssh/known_hosts中

文件中的内容为：

配置远程服务器相关信息

这一步主要是为了简化登录，因为我们的用户名可能会很长，而且ip地址也不太好记

创建config文件

第一步进入.ssh文件夹，然后在.ssh文件夹下创建config文件

配置config文件

Host server
    HostName IP地址或域名 	·
    User 用户名
1
2
3

经过上面的配置之后我们可以在直接用server来代替之前输入的user@hostname
也就是说我们直接输入ssh server，然后再输入密码就可以登陆到我们远程服务器上。

配置密钥登陆

先创建密钥

ssh-keygen
1

执行完上面命令后我们会发现.ssh目录下多了两个文件id_rsa和id_rsa.pub
id_rsa:私钥，一般是不能给别人看的
id_rsa.pub:公钥，可以给别人看，我们登录要用的

配置密钥文件

将公钥（id_rsa.pub）中的内容复制到server中的~/.ssh/authorized_keys文件中即可

一键添加公钥

ssh-copy-id-server
1

执行命令

格式

ssh user@hostname command
1

举个栗子：

ssh server ls -a
1

scp传文件

copy文件

格式：

scp source destination
1

source:源文件路径
destination:目标文件路径
含义：将source中的内容copy到destination中

copy文件夹

格式：

scp -r ~/tmpyserver:homework/
1

-r:在scp中==-r==一定要放在scp后和源路径之前,这个-r应该表示的是文件夹的含义我们在删除文件夹时也用到rm filename -r
含义：将本地家目录下的tmp文件copy到myserver中的/home/arc目录下

scp -r server:homework .
1

含义：将本地家目录下的tmp文件copy到myserver中的/home/arc目录下

配置我们的vim和tmux

scp ~/.vimrc ~/.tmux.conf server:
1
