SSH連接 提示 ssh_exchange_identification: Connection closed by remote host


今天想把服務器的安裝包遠程上傳到另一台服務器上去 執行 scp命令 結果提示 ssh_exchange_identification: Connection closed by remote host

 

執行命令 ssh -v root@10.0.0.83得出以下提示

[root@localhost .ssh]# ssh -v root@10.0.0.98
OpenSSH_7.4p1, OpenSSL 1.0.2k-fips 26 Jan 2017
debug1: Reading configuration data /root/.ssh/config
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 58: Applying options for *

debug1: Connection established.

經查看 是在.ssh目錄下有一個config配置文件,配置文件內容如下

[root@localhost .ssh]# cat /root/.ssh/config
# 如果是以域名訪問的則添加如下內容:
# host xxx
# HostName xxx.com
# Port 3333
# 如果以ip訪問的,則添加如下內容:
#Host neiwang
#User git
HostName "10.0.0.51"
Port 10580
IdentityFile ~/.ssh/jenkins

 

這個配置文件的作用是可以指定不同的主機的連接的sshx信息

解決方法:

需要修改~/.ssh/config文件

[root@localhost .ssh]# cat /root/.ssh/config
# 如果是以域名訪問的則添加如下內容:
# host xxx
# HostName xxx.com
# Port 3333
# 如果以ip訪問的,則添加如下內容:
#Host neiwang
#User git

##指定各自的主機名,用於區分  
Host git     
HostName "10.0.0.51"
Port 10580
IdentityFile ~/.ssh/jenkins

Host oth
HostName 10.0.0.83
Port 22
User root

~/.ssh/config 配置文件的具體作用和用法
