环境配置
设置用户签名
配置用户名： git config --global user.name 你的用户名
配置邮箱： git config --global user.email 注册的邮箱
配置好之后，可以用git config --global --list命令查看配置是否OK
$ git config --global --list
user.name=xxx
user.email=xxx@163.com
设置sshKey
生成新的rsa密钥：ssh-keygen -t rsa -C ‘注册GitHub的邮箱’
ssh-keygen -t rsa -C xxx@163.com
一直回车就可以，即不设置密码。
$ ssh-keygen -t rsa -C xxx@163.com
Generating public/private rsa key pair.
Enter file in which to save the key (/home/king/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/king/.ssh/id_rsa
Your public key has been saved in /home/king/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:n+yyy xxx@163.com
The key's randomart image is:
+---[RSA 3072]----+
| .*=.+. |
| = +=o= o |
| * ++ o . |
| o . o.. . |
| o * . S o |
|. X o o = + |
| + + .. = * |
|..o . o E |
|.o== . |
+----[SHA256]-----+
此时已经生成了ssh ras的密钥：
$ ls $HOME/.ssh
authorized_keys id_rsa id_rsa.pub known_hosts
设置github的SSH key
将上面生成的ssh公钥复制进去。
