ansible批量部署服务

ansible的安装和操作，并编写一个docker部署的示例

ansible-playbook使用实例（分发文件，执行脚本）

配置文件




ansible在使用配置文件时按照以下顺序优先配置：

export ANSIBLE_CONFIG

./ansible.cfg

~/.ansible.cfg

/etc/ansible/ansible.cfg

如果以上顺序没有找到配置文件ansible会自动使用默认配置

可以去github上把默认配置拿下来：

https://raw.githubusercontent.com/ansible/ansible/devel/examples/ansible.cfg
# To generate an example config file (a "disabled" one with all default settings, commented out):
#               $ ansible-config init --disabled > ansible.cfg

# Also you can now have a more complete file by including existing plugins:
# ansible-config init --disabled -t all > ansible.cfg

把它放到/etc/ansible/目录

日常技巧

sudo

没密码的sudo

cat /etc/ansible/agent.yml
---
- hosts: all
  become: yes
  become_method: sudo
  remote_user: ops
  roles:
    - ag_conf

#当然 shell 里面也要写sudo

ansible intra -m copy -a "src=/home/evan/data/devops/node-v14.17.6-linux-x64.tar.xz  dest=/root/"

ansible 122 -m copy -a "src=/home/evan/data/devops/jdk/jdk-8u212-linux-x64.rpm dest=/root/"
