ssh connect不使用来自config

我正在尝试设置与gitlab.com的ssh连接。我有相应的身份文件，如果我明确使用它，它可以工作。但是当我希望它从配置中读取身份文件时失败了。

这里明确用法：

ssh -v -i /root/.ssh/reshop-deploy -T git@gitlab.com

但如果我带着希望在/root/.ssh/config上运行它，我得到了：

.ssh文件夹列表：

ls -al /root/.ssh/
total 60
drwxr-x---  2 root root  4096 Apr 25 17:54 .
drwx------ 11 root root  4096 Apr 25 18:01 ..
-rw-------  1 root root  5024 Jun 13  2016 authorized_keys

-rw-r--r--  1 root root 13991 Apr 25 16:59 known_hosts
-rw-------  1 root root  3243 Apr 25 14:40 reshop-deploy

这是配置内容：

cat /root/.ssh/config 
Host gitlab
    Hostname gitlab.com
    User git
    IdentityFile ~/.ssh/reshop-deploy
    IdentitiesOnly yes

似乎忽略了身份文件，但我不明白为什么。

答案 0 :(得分：1)

您的casper.on('error', function(msg, backtrace) { this.capture('/tmp/error.png'); console.log('backtrace: ' + JSON.stringify(backtrace, null, 4)); console.log('message: ' + JSON.stringify(msg, null, 4)); console.log('check capture in /tmp/error.png'); casper.exit(1); }) 配置以~/.ssh/config开头。这意味着在它之后的所有配置指令（直到下一个Host gitlab行）只有在命令行上将服务器完全称为“Host”时才会生效，例如{{ 1}}。如果您还希望在执行gitlab或ssh gitlab时应用配置，则需要将ssh gitlab.com行更改为ssh git@gitlab.com。
