今天想把服务器的安装包远程上传到另一台服务器上去 执行 scp命令 结果提示 ssh_exchange_identification: Connection closed by remote host
执行命令 ssh -v root@10.0.0.83得出以下提示
[root@localhost .ssh]# ssh -v root@10.0.0.98

经查看 是在.ssh目录下有一个config配置文件，配置文件内容如下
[root@localhost .ssh]# cat /root/.ssh/config
# 如果是以域名访问的则添加如下内容:
# host xxx
# HostName xxx.com
# Port 3333
# 如果以ip访问的,则添加如下内容：
#Host neiwang
#User git
HostName "10.0.0.51"
Port 10580
IdentityFile ~/.ssh/jenkins
这个配置文件的作用是可以指定不同的主机的连接的sshx信息
解决方法：
需要修改~/.ssh/config文件
[root@localhost .ssh]# cat /root/.ssh/config
# 如果是以域名访问的则添加如下内容:
# host xxx
# HostName xxx.com
# Port 3333
# 如果以ip访问的,则添加如下内容：
#Host neiwang
#User git
##指定各自的主机名，用于区分
Host git
HostName "10.0.0.51"
Port 10580
IdentityFile ~/.ssh/jenkins
Host oth
HostName 10.0.0.83
Port 22
User root
扩展：
~/.ssh/config 配置文件的具体作用和用法
