ssh密钥对_sshqs

SSH密钥

1.生成ssh密钥对

不要私钥密码 连续回车 win git
ssh-keygen -t rsa -b 4096 -C "yourname or youremail""

qs@Dell MINGW64 ~/.ssh
$ ssh-keygen -t rsa -b 4096 -C "qs"
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/qs/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/qs/.ssh/id_rsa
Your public key has been saved in /c/Users/qs/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:w+FK6G7tG7TCxhSPbD7j/o4FdUwg533xzFh5GCC9/Sc qs
The key's randomart image is:
+---[RSA 4096]----+
|    . o.o.o.o+   |
|     + + ..Bo .  |
|    . o = oo+.   |
|   . * + o. .    |
|    B + S    .   |
|   B + o .    E .|
|    X.=        o |
|   +.*..         |
|   o=+=.         |
+----[SHA256]-----+

2. 发布公钥给服务器

ssh-copy-id -i ~/.ssh/id_rsa.pub yourname@hostname

# win
ssh-copy-id -i /c/Users/yourname/.ssh/id_rsa.pub yourname@hostname
#linux
ssh-copy-id -i ~/.ssh/id_rsa.pub yourname@hostname

root@10.0.0.5's password:

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'root@10.0.0.5'"
and check to make sure that only the key(s) you wanted were added.

阿里云主机断连

vim /etc/ssh/sshd_config
 
ClientAliveInterval 30
ClientAliveCountMax 86400
# #
# 1、客户端每隔多少秒向服务发送一个心跳数据

# 2、客户端多少秒没有相应，服务器自动断掉连接
