git clone github/gitee远程仓库,使用ssh协议,并且走本地的http代理(端口3128)。
运行环境是Ubuntu 20.04。
修改~/.ssh/config
文件:
# github.com
Host github.com
Hostname ssh.github.com
User git
Port 443
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa # id_rsa改成你的ssh密钥的文件名
ProxyCommand nc -X connect -x 127.0.0.1:3128 %h %p # 127.0.0.1:3128改成你的代理的ip:port
ServerAliveInterval 20
Hostname ssh.github.com
和ProxyCommand nc -X connect -x 127.0.0.1:3128 %h %p
定义对服务器 github.com 的 ssh 调用应该重新路由到端口 3128 上的代理服务器 127.0.0.1,并且服务器不应该是 github.com 而是更改为ssh.github.com。这是 github 允许使用 git 或 ssh 协议通过 https(端口 443)连接到服务器(That is the server where github allows you to use the git or ssh protocol to connect to over https (port 443).)。
nc
或/usr/bin/nc
是实用程序 Netcat,它为我们完成更改主机名和端口号的工作。在一些Linux服务器上,是默认安装的。
ServerAliveInterval 20
通过每 20 秒发送一个数据包来确保连接保持活动状态,以防止“管道破裂”。用户 git 确保您不会以本地 Linux 用户身份连接到 github.com,而是以用户 git 身份连接。
注意,以上是走了代理,如果不需要走代理,只需要如下配置:
# github.com
Host github.com
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa # id_rsa改成你的ssh密钥的文件名
仿照github的配置
# gitee.com
Host gitee.com
Hostname gitee.com
User git
Port 443
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
ProxyCommand nc -X connect -x 127.0.0.1:3128 %h %p
ServerAliveInterval 20
无法连接,使用ssh -Tv gitee.com
进行debug,返回400 Bad Request

原因是gitee不支持443端口的ssh服务。
去官方issue查看,2年前就有人提问(https://gitee.com/oschina/git-osc/issues/I38LRU)
但现在都还不支持非22端口的ssh服务:
使用https替代,更改git/ssh地址为https地址。
git config --global url."https://".insteadof "git://"
git config --global url."https://github.com/".insteadof "git@github.com:"
(可选)记住git账号密码
git https记住密码的方法 https://blog.csdn.net/AV_woaijava/article/details/100887704
git config --global credential.helper store
会在~/.gitconfig
文件中生成下面的配置。
[credential]
helper = store
登录过后的账号密码,会记录在~/.git-credentials
文件中
格式:
协议://username:password@git域名
如:
https://nefu_ljw:xxx@gitee.com
