git使用錯誤記錄及解決

agent refused operation Permission denied (publickey) Error

異常及解決方案

錯誤描述 sign_and_send_pubkey: signing failed: agent refused operation
Permission denied (publickey)

當你在 Linux 電腦的終端下面經過 SSH 連接到 coding.net 或 github.com 時，你或許會看到以下代碼:

sign_and_send_pubkey: signing failed: agent refused operation 
Permission denied (publickey).

此時咱們能夠執行以下命令:

ssh -T git@git.coding.net

或者：

ssh -vT git@git.coding.net

咱們或許將看到

OpenSSH_7.2p2 Ubuntu-4ubuntu2.1, OpenSSL 1.0.2g  1 Mar 2016

解決辦法經過 ssh-add

eval "$(ssh-agent -s)"

咱們會看到：

Agent pid 25534

執行下面代碼：

ssh-add

顯示以下即成功：

Identity added: /home/chen/.ssh/id_rsa (/home/chen/.ssh/id_rsa)

若是你是多個公鑰管理，你只需添加相應的文件，好比我在 bitbucket.org 下的公鑰爲 /home/chen/.ssh/bitbucket.id_rsa.pub 操做以下：

ssh-add /home/chen/.ssh/bitbucket.id_rsa.pub

ssh-add 命令詳細介紹

語法

ssh-add [-cDdLlXx] [-t life] [file ...]

ssh-add -s pkcs11 

ssh-add -e pkcs11

參數說明

-D ：刪除ssh-agent中的全部密鑰;

-d ：從ssh-agent中的刪除密鑰;

-e : pkcs11 ：刪除 PKCS#11 共享庫 pkcs1 提供的鑰匙;

-s : pkcs11 ：添加 PKCS#11 共享庫 pkcs1 提供的鑰匙;

-L ：顯示 ssh-agent 中的公鑰;

-l ：顯示 ssh-agent 中的密鑰;

-t : life：對加載的密鑰設置超時時間，超時 ssh-agent 將自動卸載密鑰;

-X ：對 ssh-agent 進行解鎖;

-x ：對 ssh-agent 進行加鎖;

示例

把專用密鑰添加到 ssh-agent 的高速緩存中

ssh-add /home/chen/.ssh/id_rsa

從ssh-agent中刪除密鑰

ssh-add -d /home/chen/.ssh/id_rsa.pub

查看ssh-agent中的密鑰

ssh-add -l

fatal: refusing to merge unrelated histories

解決以下代碼

git pull github master --allow-unrelated-histories
