即使存在于 ssh-agent 中，Git 也会要求提供 SSH 密码

Question

我每天在我的 Mac 上使用带有 ssh-agent 的 git，它可以完美运行。但是，在我的远程开发服务器上，我应该错过一些东西，因为 远程 git 操作时无法绕过 SSH 密码提示 .

设置

key 在 ssh-agent 中列出:ssh-add -L :

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCktk2+zRYGy0RdM6HJ8JFVPjiNknK7iN8ohdCGSX9fPQ.... 
/home/user/.ssh/id_rsa.from_user@server_to_git@bitbucket

key 与 ~/.ssh/config 中的 bitbucket 相关联:

Host *
    IdentitiesOnly yes
    ServerAliveInterval 600
    ServerAliveCountMax 5
    TCPKeepAlive no
    IdentitiesOnly yes


Host bitbucket bitbucket.org
   User git
   Hostname bitbucket.org
   KexAlgorithms diffie-hellman-group1-sha1
   Identityfile  /home/user/.ssh/id_rsa.user@server_to_git@bitbucket

环境变量 export | grep SSH_A :

SSH_AGENT_PID=30294
SSH_AUTH_SOCK=/tmp/ssh-IS3rVQtFwDxF/agent.30292

代理正在运行 ps -e | grep -q ssh-agent && echo "SSH Agent is running"返回

SSH Agent is running

权限 ls -al ~/.ssh :

total 48K
drwx------  2 user user 4,0K oct.  30 18:22 .
drwxr-xr-x 18 user user 4,0K nov.   7 11:52 ..

-rw-r--r--  1 user user 2,6K oct.  30 11:02 known_hosts

我的“硬化”/etc/ssh/ssh_config :

AddressFamily inet
BatchMode no
CheckHostIP yes
Ciphers chacha20-poly1305@openssh.com,aes256-gcm@openssh.com,aes128-gcm@openssh.com,aes256-ctr,aes192-ctr,aes128-ctr

PasswordAuthentication no
PermitLocalCommand no
Port 22
Protocol 2
RSAAuthentication yes
RhostsRSAAuthentication no
StrictHostKeyChecking ask

然而

运行git clone bitbucket:team/project.git返回

Enter passphrase for key '/home/user/.ssh/id_rsa.from_user@server_to_git@bitbucket':

调试

结果ssh -v bitbucket :

有什么提示吗？

我刚刚发现 IdentitiesOnly需要公钥存在于本地机器上才能工作。
