1. 在命令行中，切换到··/git/bin/ 目录下

2.22.0_1 cd bin
➜  bin ll
total 8920
-rwxr-xr-x  1 hanbeikai  staff   2.5M  7 18  2019 git
-rwxr-xr-x  1 hanbeikai  staff   159K  7 18  2019 git-cvsserver
lrwxr-xr-x  1 hanbeikai  staff     3B  6  8  2019 git-receive-pack -> git
-rwxr-xr-x  1 hanbeikai  staff   1.4M  7 18  2019 git-shell
lrwxr-xr-x  1 hanbeikai  staff     3B  6  8  2019 git-upload-archive -> git
lrwxr-xr-x  1 hanbeikai  staff     3B  6  8  2019 git-upload-pack -> git
-r-xr-xr-x  1 hanbeikai  staff   343K  6  8  2019 gitk

2. git命令行生成公钥

ssh-keygen -t rsa

3. 然后会依次出现三行，直接按 enter

➜  bin ssh-keygen -t rsa
Generating /private rsa key pair.
Enter file in which to save the key (/Users/hanbeikai/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/hanbeikai/.ssh/id_rsa.
Your public key has been saved in /Users/hanbeikai/.ssh/id_rsa.pub.

4. .ssh/目录下生成对应的公钥，私钥

-rw-------  1 hanbeikai  staff   2.5K  8 30 12:09 id_rsa
-rw-r--r--  1 hanbeikai  staff   581B  8 30 12:09 id_rsa.pub
