ansible服务
填写hosts指定主机范围和控制节点后创建一个脚本，可以利用简化脚本
1. 在linux1上安装系统自带的ansible-core,作为ansible控制节点,linux2-linux7作为ansible的受控节点
Linux1
Linux1-7 Yum install ansible-core -y
Vi /etc/ansible/hosts
添加
[linux1]
linux1.skills.lan
[linux2-linux7]
linux2.skills.lan
linux3.skills.lan
linux4.skills.lan
linux5.skills.lan
linux6.skills.lan
linux7.skills.lan在linux1编写/root/skills.yul剧本，仅在linux1节点运行，实现如下功能:为主控节点和受控节点同时安装lrzsz软件
vim /etc/ansible/ansible.cfg添加忽略验证
[defaults]
host_key_checking = False 
**root@linux1 \~#
ansible-playbook /root/skills.yml（2）编写/root/host.yml 剧本，实现在所有linux主机的/root 目录下创建一个host.txt 文件，文件内容为："ansible脚本测试，主机名为：hostname"，hostname为各对应主机的FQDN全名。
---
- hosts: all
tasks:
- name: 1
file:
path: /root/host.txt
state: touch
- name: 1
lineinfile:
path: /root/host.txt
line: "Hostname is: {{ ansible_fqdn }}"
create: yes- hosts: server
gather_facts: no
tasks:
- name: touch file
file: path="/root/ansible.txt" state=touch
- hosts: client
gather_facts: no
tasks:
- name: copy file
copy: src="/root/ansible.txt" dest="/root/"2022国赛
5.在linux1 上安装ansible，作为ansible的控制节点。linux2-linux7作 为ansible 的受控节点。在linux1编写/root/skills.yaml剧本，实现在linux1 创建文件/root/ansible.txt，并将该文件复制到所有受控节点的/root目录。
- hosts: all
tasks:
- name: 123
copy:
content: "123"
dest: /root/ansible.txt在linux1编写cron.yaml脚本实现linux2-linux7每格一小时定时备份/var/log/message/到data_log下，备份策略为递归
- hosts: all
tasks:
- name: Ensure directory exists for log
file:
path: /data_log
state: directory
- name: Schedule cron job for log rotation
cron:
name: Rotate Log
minute: "0"
hour: "*/1"
day: "*"
month: "*"
weekday: "*"
job: "cat /var/log/messages >> /data_log/message && echo '' > /var/log/messages"竞赛培训请联系主页！
