ansible踩坑指南

1.ansible Missing sudo password

  1.1尝试使用该选项-kK。它将提示输入密码。

$ ansible-playbook mail.yml -kK 
SSH password: 
BECOME password[defaults to SSH password]: 

• -k，--ask-pass：询问连接密码
• -K，--ask-become-pass：询问特权升级密码

1.2  You can specificy the sudo password when running the Ansible playbook:

ansible-playbook playbook.yml -i inventory.ini --extra-vars "ansible_sudo_pass=yourPassword"

  1.3将此添加到您的/ etc / sudoers文件

## Allows people in group wheel to run all commands
%wheel  ALL=(ALL)       ALL

## Same thing without a password
# %wheel        ALL=(ALL)       NOPASSWD: ALL
username-u-want-to-allow        ALL=(ALL)       NOPASSWD: ALL

 2. ansible出现Failed to connect to the host via ssh

  2.1 公钥验证出现问题一般检查selinux是否关闭,还有就是authorized_keys权限是否为600
