错误：无法通过ssh连接到主机

Question

我想学习可靠，并且遵循o'riley Ansible Up和正在运行的书。

在本书的入门部分，它要求我安装ansible，VirtualBox和流浪者，然后通过CLI运行：

vagrant init ubuntu/trusty64 

vagrant up 

之后我可以通过无业游民SSH或通过ssh到VM：

ssh vagrant@127.0.0.1 -p 2222 -i /Users/XXX/playbooks/.vagrant/machines/default/virtualbox/private_key 

接下来是创建hosts文件看起来像这样：

testserver ansible_ssh_host=127.0.0.1 ansible_ssh_port=2222 \ ansible_ssh_user=vagrant \ ansible_ssh_private_key_file=.vagrant/machines/default/virtualbox/private_key 

最后运行此命令：

ansible TESTSERVER -i主机-m平

这让我：

testserver | UNREACHABLE! => { 
    "changed": false, 
    "msg": "Failed to connect to the host via ssh.", 
    "unreachable": true 
} 

添加-vvv打动了我：

No config file found; using defaults 
<127.0.0.1> ESTABLISH SSH CONNECTION FOR USER: None 
<127.0.0.1> SSH: EXEC ssh -C -q -o ControlMaster=auto -o ControlPersist=60s -o Port=2222 -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey -o PasswordAuthentication=no -o ConnectTimeout=10 -o ControlPath=/Users/XXX/.ansible/cp/ansible-ssh-%h-%p-%r 127.0.0.1 '/bin/sh -c '"'"'(umask 77 && mkdir -p "` echo $HOME/.ansible/tmp/ansible-tmp-1468541275.7-255802522359895 `" && echo ansible-tmp-1468541275.7-255802522359895="` echo $HOME/.ansible/tmp/ansible-tmp-1468541275.7-255802522359895 `") && sleep 0'"'"'' 
testserver | UNREACHABLE! => { 
    "changed": false, 
    "msg": "Failed to connect to the host via ssh.", 
    "unreachable": true 
} 

我试图修改ansible_ssh_private_key_file hosts文件指向私钥的完整路径，但仍不起作用：

ansible testserver -i hosts -m ping -vvv 
No config file found; using defaults 
<127.0.0.1> ESTABLISH SSH CONNECTION FOR USER: None 
<127.0.0.1> SSH: EXEC ssh -C -q -o ControlMaster=auto -o ControlPersist=60s -o Port=2222 -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey -o PasswordAuthentication=no -o ConnectTimeout=10 -o ControlPath=/Users/XXX/.ansible/cp/ansible-ssh-%h-%p-%r 127.0.0.1 '/bin/sh -c '"'"'(umask 77 && mkdir -p "` echo $HOME/.ansible/tmp/ansible-tmp-1468541370.61-137685863794569 `" && echo ansible-tmp-1468541370.61-137685863794569="` echo $HOME/.ansible/tmp/ansible-tmp-1468541370.61-137685863794569 `") && sleep 0'"'"'' 
testserver | UNREACHABLE! => { 
    "changed": false, 
    "msg": "Failed to connect to the host via ssh.", 
    "unreachable": true 
} 

这是我的Ansible版本：

ansible --version ansible 2.1.0.0 配置文件= 配置模块搜索路径=默认W/O覆盖

任何人有任何想法，为什么ansible ISN连接到我的流浪VM？

我没有看到任何库存变量超过第一个在ssh命令中生效的变量。你的库存文件真的是这样吗？

testserver ansible_ssh_host=127.0.0.1 ansible_ssh_port=2222 \ ansible_ssh_user=vagrant \ ansible_ssh_private_key_file=.vagrant/machines/default/virtualbox/private_key 

你不应该在那里有反斜杠。直接重新格式化为

testserver ansible_ssh_host=127.0.0.1 ansible_ssh_port=2222 ansible_ssh_user=vagrant ansible_ssh_private_key_file=.vagrant/machines/default/virtualbox/private_key 

但是，从长远来看，您可能需要split these out into separate host_vars files。
