ssh-copy-id
|
||
===
|
||
|
||
把本地的ssh公钥文件安装到远程主机对应的账户下
|
||
|
||
## 补充说明
|
||
|
||
**ssh-copy-id命令** 可以把本地主机的公钥复制到远程主机的authorized_keys文件上，ssh-copy-id命令也会给远程主机的用户主目录（home）和`~/.ssh`, 和`~/.ssh/authorized_keys`设置合适的权限。
|
||
|
||
**ssh-copy-id** 使用ssh登陆远程服务器，一般是通过密码校验用户身份，所以在sshd的配制中应该启用密码校验方式：
|
||
将/etc/ssh/sshd_config中的PasswordAuthentication设置为yes，之后重启sshd
|
||
### 语法
|
||
|
||
```shell
|
||
ssh-copy-id [-i [identity_file]] [user@]machine
|
||
```
|
||
|
||
### 选项
|
||
|
||
```shell
|
||
-i：指定公钥文件
|
||
```
|
||
|
||
### 实例
|
||
|
