Ansible 版本 2.1
我有一个库存文件hosts
[nodes]
host1
host2
...
一个简单的剧本site.yml
---
- hosts: all
tasks:
- include: tasks/main.yml
如果我刚开始表演,
ansible-playbook -i hosts site.yml -vvvv
我在所有主机上都遇到此错误,
ESTABLISH SSH CONNECTION FOR USER: None
fatal: [host1]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh.", "unreachable": true}
...
然而,阅读Ansible 库存doc,我添加ansible_user
到hosts
文件中,
[nodes]
host1 ansible_user=root
host2 ansible_user=root
...
这解决了SSH CONNECTION UNREACHABLE
错误。但是,我必须ansible_user=root
在所有主机旁边添加吗?或者有更简单的方法可以做到这一点?
答案1
检查示例/默认ansible.cfg
文件,您会在下方找到以下内容[defaults]
:
# default user to use for playbooks if user is not specified
# (/usr/bin/ansible will use current user as default)
#remote_user = root
取消注释remote_user
并将用户设置为您想要登录的用户。
Ansible 从哪里获取ansible.cfg
?同一个文件解释道:
# nearly all parameters can be overridden in ansible-playbook
# or with command line flags. ansible will read ANSIBLE_CONFIG,
# ansible.cfg in the current working directory, .ansible.cfg in
# the home directory or /etc/ansible/ansible.cfg, whichever it
# finds first

另一种方法是使用--user
定义远程 ssh 用户。输入ansible-playbook --help
以了解更多信息。这是我的典型命令:
ansible-playbook -i hosts site.yml --user <user> --ask-pass -vvvv
--ask-pass
将提示输入密码--user

除了修改之外ansible.cfg
,您还可以为“所有”组或其他组定义变量
https://docs.ansible.com/ansible/latest/user_guide/intro_inventory.html#group-variables
[all:vars]
ansible_user = root
ansible_port = 22
