Question

我使用Ubuntu 15.10运行计算机，并尝试使用Vagrant运行Ansible。

在开始之前，我想说我对服务器管理一无所知，特别是Ansible。

我打算以这种方式运行系统的原因是因为我已经开始研究需要安装的项目。

毕竟，我遇到的问题是，在配置Vagrant时，我收到以下消息

<aaa.dev> ESTABLISH CONNECTION FOR USER: vagrant
<aaa.dev> REMOTE_MODULE setup
<aaa.dev> EXEC ssh -C -tt -vvv -o UserKnownHostsFile=/dev/null -o IdentitiesOnly=yes -o IdentityFile=/media/merianos/Large Internal/Vagrant/ansible-project/.vagrant/machines/default/virtualbox/private_key -o ForwardAgent=yes -o ControlMaster=auto -o ControlPersist=60s -o ControlPath="/home/merianos/.ansible/cp/%h-%r" -o StrictHostKeyChecking=no -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey -o PasswordAuthentication=no -o User=vagrant -o ConnectTimeout=30 aaa.dev /bin/sh -c 'mkdir -p $HOME/.ansible/tmp/ansible-tmp-1446622406.54-199921739516776 && chmod a+rx $HOME/.ansible/tmp/ansible-tmp-1446622406.54-199921739516776 && echo $HOME/.ansible/tmp/ansible-tmp-1446622406.54-199921739516776'
fatal: [aaa.dev] => SSH Error: ControlPath too long
It is sometimes useful to re-run the command using -vvvv, which prints SSH debug output to help diagnose the issue.

那么，有没有人帮我解决这个问题呢？

只是说我已尝试过这篇文章：https://github.com/ansible/ansible/issues/11536我将control_path中的ansible.cfg更改为control_path = %(directory)s/%%h-%%r，但仍无效。

注意我的安装路径包含一个我无法删除它的空间，因为在同一个硬盘上运行了许多其他项目，并且所有项目的配置都很大。我不知道这个空间是不是问题，但我只是说了。

更新＃1

我改变之前的结果：

<aaa.dev> ESTABLISH CONNECTION FOR USER: vagrant
<aaa.dev> REMOTE_MODULE setup
<aaa.dev> EXEC ssh -C -tt -vvv -o UserKnownHostsFile=/dev/null -o IdentitiesOnly=yes -o IdentityFile=/media/merianos/Large Internal/Vagrant/ansible-project/.vagrant/machines/default/virtualbox/private_key -o ForwardAgent=yes -o ControlMaster=auto -o ControlPersist=60s -o ControlPath="/home/merianos/.ansible/cp/ansible-ssh-%h-%p-%r" -o StrictHostKeyChecking=no -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey -o PasswordAuthentication=no -o User=vagrant -o ConnectTimeout=30 aaa.dev /bin/sh -c 'mkdir -p $HOME/.ansible/tmp/ansible-tmp-1446628138.53-155680153347939 && chmod a+rx $HOME/.ansible/tmp/ansible-tmp-1446628138.53-155680153347939 && echo $HOME/.ansible/tmp/ansible-tmp-1446628138.53-155680153347939'
fatal: [aaa.dev] => SSH Error: ControlPath too long

control_path = %(directory)s/%%h-%%r的结果：

<aaa.dev> ESTABLISH CONNECTION FOR USER: vagrant
<aaa.dev> REMOTE_MODULE setup
<aaa.dev> EXEC ssh -C -tt -vvv -o UserKnownHostsFile=/dev/null -o IdentitiesOnly=yes -o IdentityFile=/media/merianos/Large Internal/Vagrant/ansible-project/.vagrant/machines/default/virtualbox/private_key -o ForwardAgent=yes -o ControlMaster=auto -o ControlPersist=60s -o ControlPath="/home/merianos/.ansible/cp/%h-%r" -o StrictHostKeyChecking=no -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey -o PasswordAuthentication=no -o User=vagrant -o ConnectTimeout=30 aaa.dev /bin/sh -c 'mkdir -p $HOME/.ansible/tmp/ansible-tmp-1446628320.4-231606404275563 && chmod a+rx $HOME/.ansible/tmp/ansible-tmp-1446628320.4-231606404275563 && echo $HOME/.ansible/tmp/ansible-tmp-1446628320.4-231606404275563'

设置ssh_args = -o ControlMaster=off后，我得到以下结果：

<aaa.dev> ESTABLISH CONNECTION FOR USER: vagrant
<aaa.dev> REMOTE_MODULE setup
<aaa.dev> EXEC ssh -C -tt -vvv -o UserKnownHostsFile=/dev/null -o IdentitiesOnly=yes -o IdentityFile=/media/merianos/Large Internal/Vagrant/ansible-project/.vagrant/machines/default/virtualbox/private_key -o ForwardAgent=yes -o ControlMaster=auto -o ControlPersist=60s -o ControlPath="/home/merianos/.ansible/cp/ansible-ssh-%h-%p-%r" -o StrictHostKeyChecking=no -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey -o PasswordAuthentication=no -o User=vagrant -o ConnectTimeout=30 aaa.dev /bin/sh -c 'mkdir -p $HOME/.ansible/tmp/ansible-tmp-1446628489.4-10074395967553 && chmod a+rx $HOME/.ansible/tmp/ansible-tmp-1446628489.4-10074395967553 && echo $HOME/.ansible/tmp/ansible-tmp-1446628489.4-10074395967553'

通常，对于我所做的每个修改，错误消息似乎都是相同的，可能是从其他级别发生的配置，而不是ansible.cfg。

不幸的是，我不知道在哪里可以找到这个位置:(

Answer 1

我在similar question中描述了这个问题。

您需要将其更改为更短的内容（如果您有长主机名）。对于测试用例，您可以尝试./master，但对于实际用例，您应该至少使用./s/%%h-%%r。

Answer 2

Ansible中documentation for OpenSSH specific settings的第一句话说：

在[ssh_connection]标头下，以下设置可供SSH连接调整。

因此，您需要将ssh_args变量放在[ssh_connection]的{{1}}部分中，例如：

ansible.cfg

事实上，使用空值覆盖[defaults] timeout = 600 [ssh_connection] ssh_args = -o ControlMaster=off会禁用Ansible中ssh_args / ControlMaster / ControlPersistent的默认值，因此它应该只是：

ControlPath

Ansible：SSH错误：ControlPath太长
