1.从远程仓库clone到本地
2.生成SSH秘钥,为push做准备
在Ubuntu命令行输入一下内容
bash
[root@localhost ~]# ssh-keygen -t rsa <== 建立密钥对,-t代表类型,有RSA和DSA两种
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): <==密钥文件默认存放位置,按Enter即可
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase): <== 输入密钥锁码,或直接按 Enter 留空
Enter same passphrase again: <== 再输入一遍密钥锁码
Your identification has been saved in /root/.ssh/id_rsa. <== 生成的私钥
Your public key has been saved in /root/.ssh/id_rsa.pub. <== 生成的公钥
The key fingerprint is:
SHA256:K1qy928tkk1FUuzQtlZK+poeS67vIgPvHw9lQ+KNuZ4 root@localhost.localdomain
The key's randomart image is:
+---[RSA 2048]----+
| +. |
| o * . |
| . .O + |
| . *. * |
| S =+ |
| . =... |
| .oo =+o+ |
| ==o+B*o. |
| oo.=EXO. |
+----[SHA256]-----+
最后生产SSH Key的秘钥对, id_rsa 是私钥,不能泄露出去, id_rsa.pub 是公钥,可以放心地告诉任何人。
按这个目录去.ssh目录下找到id_rsa.pub这个文件夹打开复制全部内容。
在github上面添加公钥将上面内容复制到下图位置
输入ssh -T git@github.com,查看SSH公钥密钥是否配置成功,出现下面信息表明成功
3.将更新了的本地仓库push到远程仓库
第一次push时需要先链接远程仓库
后面提交只要输入下面四句命令即可
