我正在尝试使用Capistrano将Rails应用程序部署到服务器。
在我的本地环境中，我运行了“ 生产上限部署”，但出现错误。

git stdout: Nothing written

所以我去服务器端检查服务器是否可以与Github通信。它调出了没有。

请注意，我已经使用'ssh-copy-id'将本地公用密钥复制到服务器了
deploy@xx.xx.xx.xx:~/.ssh$ ls -la
total 16
drwx------ 2 deploy deploy 4096 Nov 27 01:55 .
drwxr-xr-x 10 deploy deploy 4096 Nov 27 05:18 ..
-rw------- 1 deploy deploy 3724 Nov 27 12:37 authorized_keys
-rw-r--r-- 1 deploy deploy 1326 Nov 27 01:57 known_hosts
另外，我尝试将密钥添加到ssh-agent。但失败了。
deploy@xx.xx.xx.xx:~/.ssh$ eval "$(ssh-agent -s)"
Agent pid 4417
deploy@xx.xx.xx.xx:~/.ssh$ ssh-add ~/.ssh/authorized_keys
Error loading key "/home/deploy/.ssh/authorized_keys": invalid format
服务器端是否只有我的公共密钥。对？不是私钥。我在正确的轨道上吗？

建议@ZedTuX
我在服务器端生成了另一个ssh密钥集。并将公共密钥添加到github repo，以便它可以读取/写入。所以我在服务器端测试了git pull and push。有用。仍然出现此错误。当我尝试在本地部署时。
DEBUG [1b7b3349] error: could not lock config file config: Permission denied
DEBUG [1b7b3349] fatal: could not set 'remote.origin.url' to 'git@github.com:maskeduser1/repo1.git'
这对我来说没有意义，因为我什至可以--set-upstream到Github。为什么我会收到此错误？
