使用 SSH 连接 Github 提交代码
生成 ssh 密钥
ssh-keygen -t ed25519 -C "email@email.com"
## 生成如下文件.ssh/id_ed25519.pub
Generating public/private ed25519 key pair.
Enter file in which to save the key (/home/dev/.ssh/id_ed25519):
Enter passphrase (empty for no passphrase): # 输入密码
Enter same passphrase again: #输入密码
Your identification has been saved in /home/dev/.ssh/id_ed25519
Your public key has been saved in /home/dev/.ssh/id_ed25519.pub
dev@ALLENYS:~/.ssh$ ls
id_ed25519 id_ed25519.pub known_hosts known_hosts.old
拷贝.ssh/id_ed25519.pub 文件内容到 github 帐号下的SSH and GPG keys
代码库配置 ssh
到代码库的文件夹中执行以下命令
git remote set-url origin git@github.com:user/repo.git
配置 ssh-agent
检查是否安装 ssh-agent
echo $SSH_AGENT_PID #输出进程id 若没有输出需要执行启动
ssh-agent -k
eval "$(ssh-agent -s)" # 在当前shell启动
ssh-add ~/.ssh/id_ed25519 # 将私钥添加到ssh-agent
dev@ALLENYS:/home/project/subsequent-star$ ssh-add ~/.ssh/id_ed25519
Enter passphrase for /home/dev/.ssh/id_ed25519:
Identity added: /home/dev/.ssh/id_ed25519 (email@email.com)
自动开启 ssh-agent
自动启动 ssh-agent 可以在打开 bash 或 Git shell 时自动运行 ssh-agent。 复制以下行并将其粘贴到 shell 中的 ~/.profile 或 ~/.bashrc 文件中：
dev@ALLENYS:~$ vim ~/.profile
dev@ALLENYS:~$
env=~/.ssh/agent.env
agent_load_env () { test -f "$env" && . "$env" >| /dev/null ; }
agent_start () {
(umask 077; ssh-agent >| "$env")
. "$env" >| /dev/null ; }
agent_load_env
# agent_run_state: 0=agent running w/ key; 1=agent w/o key; 2=agent not running
agent_run_state=$(ssh-add -l >| /dev/null 2>&1; echo $?)
if [ ! "$SSH_AUTH_SOCK" ] || [ $agent_run_state = 2 ]; then
agent_start
ssh-add
elif [ "$SSH_AUTH_SOCK" ] && [ $agent_run_state = 1 ]; then
ssh-add
fi
unset env
## 后续
dev@ALLENYS:~$ source ~/.profile
Enter passphrase for /home/dev/.ssh/id_ed25519: #密码
ssh-add 向身份验证代理 ssh-agent 添加私钥标识。当没有参数运行时，它会添加文件~/.ssh/id_rsa、
/.ssh/id_ecdsa、/.ssh/id_ecdsa_sk、/.ssh/id_ed25519、/.ssh/id_ed25519_sk 和~/.ssh/id_dsa
