git bash

一、就是单纯没网了

ssh: Could not resolve hostname github.com: Name or service not known
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
FATAL Something's wrong. Maybe you can find the solution here: https://hexo.io/docs/troubleshooting.html
Error: Spawn failed
    at ChildProcess.<anonymous> (E:\Myblog\node_modules\hexo-util\lib\spawn.js:51:21)
    at ChildProcess.emit (node:events:513:28)
    at cp.emit (E:\Myblog\node_modules\cross-spawn\lib\enoent.js:34:29)
    at ChildProcess._handle.onexit (node:internal/child_process:291:12)

二、多个免密怎么搞

我之前已经有一个git和github间的免密登录了；

之后又配置了一个vscode和虚拟机之间的免密登录，把上面那个覆盖了，之后我git更新博客的时候，出错了

生成的id_rsa不重名就行了

之后改改主机上的.ssh/config，配置如下

Host github.com
    HostName ssh.github.com
    Port 443
    User git
    IdentityFile ~/.ssh/id_rsa
#centos	
Host 192.168.1.89
    Hostname 192.168.1.89
    User root
    IdentityFile ~/.ssh/id_rsa_centos

三、git -T git @github.com出错

kex_exchange_identification: Connection closed by remote host

我的是因为上面config里，手写成了HostName github.com，少一个 ssh. 啊
