安装依赖
<code>

Linux yum
install expect
apt-get install expect

</code>

安装 autossh，（文件地址 ~/.autosshrc）

<code>
$ git clone https://github.com/FeeiCN/autossh.git
$ sudo cp autossh/autossh /usr/local/bin/

</code>

配置服务器

<code>
$ cat ~/.autosshrc
server_name|192.168.1.110|root|password|port|is_bastion

</code>

:!: 重新布置服务器，密码更改以后需要取消原来的key

<code javascript>
ssh-keygen -R 217.160.61.19
// 出现错误 Offending key for IP in /root/.ssh/known_hosts:3 删除第3行
sed -i '3d' ~/.ssh/known_hosts
</code>
===== Windows =====

安装 putty ，然后建立一个桌面快捷方式：

<code>
"C:\Program Files\PuTTY\putty.exe" -ssh -l <username> -pw <password> -i "servername" -P 22 192.168.0.*

</code>


===== ssh-keygen =====

<code bash>
ssh-keygen # 生成新的公钥，不需要额外设置 ssh-keygen -t rsa 
ssh-copy-id -i ~/.ssh/id_rsa.pub ubuntu@62.143.173.13
</code>

设置完登录一次，填写密码，以后就不需要了。（查看自己的公钥 <color #ff7f27>''%%cat ~/.ssh/id_rsa.pub%%''</color>）
