使用Git生成github和gitlab各自的钥匙
注: windows的命令行不太好用, 建议用Windows的朋友安装gitbash
ssh钥匙文件默认存储于操作系统当前用户目录的.ssh子目录下
为了生成自命名的钥匙, 切换到.ssh作为当前目录

$ cd ~ $ cd .ssh |

之后在~/.ssh目录下将新增6个文件
- github_id_rsa
- github_id_rsa.pub
- gitlab_id_rsa
- gitlab_id_rsa.pub
- gitlab_gyenno_id_rsa
- gitlab_gyenno_id_rsa.pub
打开github和gitlab网页, 将github_id_rsa.pub,gitlab_id_rsa.pub,gitlab_gyenno_id_rsa.pub分别配置到对应的sshkey中
注: 此处不上传公钥(.pub)的话, 连接时将提示Permission denied (publickey).
自定义config文件, 指导本地git访问不同的仓库使用不同钥匙
1 2 3 |
$ cd ~ $ cd .ssh $ vim config |
config 内容如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
# github Host github HostName github.com User git IdentityFile ~/.ssh/github_id_rsa # gitlab(个人) Host gitlab HostName gitlab.com User git IdentityFile ~/.ssh/gitlab_id_rsa # gitlab(公司) Host gitlab_gyenno HostName gitlab.gyenno.com User git IdentityFile ~/.ssh/gitlab_gyenno_id_rsa |
测试连接是否成功
1 2 3 4 5 6 7 8 9 10 11 12 |
$ ssh -T github Enter passphrase for key 'C:/Users/ZL-arccode/.ssh/github_id_rsa': Hi arccode! You've successfully authenticated, but GitHub does not provide shell access. $ ssh -T gitlab Enter passphrase for key '/c/Users/ZL-arccode/.ssh/gitlab_id_rsa': Welcome to GitLab, username! $ ssh -T gitlab_gyenno Enter passphrase for key '/c/Users/ZL-arccode/.ssh/gitlab_gyenno_id_rsa': Welcome to GitLab, username! |
这里的github和gitlab是config中配置的host; 根据此host,git可以找到配置对应的地址
配置仓库, 让不同仓库的项目工作在不同目录
笔者配置如下:
- github工作目录:
~/workspace/github - gitlab工作目录(个人):
~/workspace/gitlab - gitlab工作目录(公司):
~/workspace/gitlab_gyenno
检查当前配置
git config --list
github配置, 提交时的用户名和email(全局)
1 2 3 |
$ cd ~/workspace/github $ git config --global user.name 'arccode' $ git config --global user.email '[email protected]' |
gitlab配置(个人), 提交时的用户名和email(局部)
1 2 3 |
$ cd ~/workspace/gitlab $ git config --local user.name 'username' $ git config --local user.email '[email protected]' |
gitlab配置(公司), 提交时的用户名和email(局部)
1 2 3 |
$ cd ~/workspace/gitlab_gyenno $ git config --local user.name 'username' $ git config --local user.email '[email protected]' |
从仓库clone项目
github
1 |
$ git clone git@github:arccode/littlebird-mybatis-generator-core.git |
原本从仓库clone项目的指令是, git clone [email protected]:arccode/littlebird-mybatis-generator-core.git
因为配置了config, 所以使用git会使用host自动查找到[email protected]
gitlab(个人)
1 |
$ git clone git@gitlab:arccode/arccode.net.git |
gitlab(公司)
1 |
$ git clone git@gitlab_gyenno:backend/GyennoMedicalCloud.git |
指令修改原因同上
执行完以上步骤，执行Git clone一直报下面的错误
git clone 解决Permission Denied (publickey)问题
需要参考下文执行
步骤三的1、2命令
eval "$(ssh-agent -s)"
ssh-add ~/.ssh/github_id_rsa
ssh-add ~/.ssh/gitlab_id_rsa
原文地址：https://blog.csdn.net/sxg0205/article/details/81412921
本地git bash 使用git clone [email protected]:***.git方式下载github代码至本地时需要依赖ssh key，遇到权限不足问题时一般都是SSH key失效或者SSH key不存在，重新创建SSH key一般就可以解决问题；
步骤一、检查本地ssh key是否存在
1、windows下 开始 -- 搜索框输入 git bash，打开git bash窗口；
2、git base窗口中输入指令 ls ~/.ssh/ 来检查ssh key是否存在；
3、如果key不存在则按照步骤二重新生成，ssh key已存在则跳过步骤二，执行步骤三；
步骤二、生成ssh key
1、继续步骤一的git bash窗口执行指令：
ssh-keygen -t rsa -b 2048 -C "你自己的邮箱地址"
修改邮箱地址为你自己的邮箱地址，注意此处邮箱地址前后的双引号为英文格式双引号；
2、指令执行后页面提示：
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/***/.ssh/id_rsa):
***表示你自己的当前登录用户名，不做修改直接回车，会将生成的rsa文件保存为默认名称
再次回车提示：
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
提示设置提交/l拉取代码到Github时需要的密码及确认密码；
设置密码后再次回车提示Your identification has been saved in.... 即表示ssh key生成成功；
步骤三、添加sshkey至ssh-agent
1、执行eval "$(ssh-agent -s)"确认ssh-agent处于开启状态，打印pid... 表示启用中；
2、执行指令ssh-add ~/.ssh/id_rsa 添加ssh key至ssh agent，此步会要求输入步骤二设置的密码；
需要注意的是此处可能报错：Could not open a connection to your authentication agent，我的解决办法是关掉当前git bash窗口，重新以管理员身份运行git bash 即解决问题；
步骤四、添加ssh key至guthub
1、登录https://github.com/，在页面右上角自己头像右边箭头处右击，弹框中进入setting功能；
2、setting界面右边菜单选择SSH and GPG keys，选择新建SSH keys，
保存即可；
步骤五：git clone下载代码
步骤结束，此时再尝试本地使用git clone方式下载代码即可；
