3-1 在 workstation 上创建名为/ansible/playbooks/users.yml 的 playbook 完成以下任务：
(1) 在agent1和agent2上分别建立如下的用户和组，并设置所有用户密码为本人学号。
(2) 在agent1上删除OaManager用户，并删除其家目录
- name: agent1 and agent2 create group user
hosts: all
gather_facts: no
vars:
group_list: ['manager','consumer']
con_list: ['1','3','5','7','9','11']
tasks:
- name: create group
group:
name: "{{ item }}"
state: present
with_items:
- "{{ group_list }}"
- name: create user ma
user:
name: "ma{{ item }}"
group: manager
password: "{{ '2103010225' | password_hash('sha512') }}"
state: present
with_sequence:
count=15
- name: create user con
user:
name: "con{{ item }}"
group: consumer
password: "{{ '2103010225' | password_hash('sha512') }}"
state: present
with_items:
- "{{ con_list }}"
- name: del user OaManager
hosts: agent1
gather_facts: no
tasks:
- name: del user
user:
name: OaManager
remove: yes
state: absent
3-2 在 workstation 上创建名为/ansible/playbooks/createUsers.yml 的 playbook 完成以下任务：

group:
name: oaUser
state: present
- name: create user usr
user:
name: "usr{{ item }}"

- "{{ emp_list }}"
- name: del user testUser
user:
name: testUser
remove: yes

4.生成硬件报告
创建一个名为/ansible/playbooks/hwreport.yml 的 playbook ，它将在所有受管节点上生成含有以下信息的输出文件 /opt/hwreport.txt ：
HardWare details:
Memory: xxMB以 MB 表示的总内存大小
BIOS: xx 版本
Disk: sda1 xxMB, sda2 xxMB.
- name: hwreport
hosts: webservers
tasks:
- name: create file
copy:
dest: /opt/hwreport.txt
content: |
- name: 2
shell: echo -e 'HardWare details':' \nMemory':' {{ ansible_memtotal_mb }} \nBIOS':' {{ ansible_bios_version }} \nsda1 ':' {{ ansible_devices.sda.partitions.sda1.size }} \nsda2 ':' {{ ansible_devices.sda.partitions.sda1.size }} ' > /opt/hwreport.txt
5.配置 cron 作业
创建一个名为/ansible/playbooks/cron.yml 的 playbook :
该 playbook 在 dbservers主机组中的受管节点上运行
配置 cron 作业，该作业每隔 2 分钟运行并执行以下命令：
xxxx-xx-xx xx:xx “ansible in progress” 【xxxx-xx-xx xx:xx为当前时间，年-月-日 时:分】
- hosts: dbservers
gather_facts: no
tasks:
- name: create cron
cron:
name: ansible in progress
minute: "*/2"
job: 'date "+%Y-%m-%d %H:%M:%S" "ansible in progress" '
6.在 workstation 上创建名为/ansible/playbooks/safty.yml,实现远程关闭agent1和agent2防火墙和selinux，并分别实现重启后保持生效。
- name: stop selinux
hosts: webservers
tasks:
- name: stop firewalld
service:
name: firewalld
state: stopped
enabled: no
- name: selinux disable
replace:
path: /etc/selinux/config
regexp: '^SELINUX=enforcing'
replace: 'SELINUX=disabled'
- name: setenforce 0
shell: " setenforce 0 "
7-1 在 workstation 上创建名为/ansible/playbooks/copyfile.yml, 拷贝来自workstation的/data/news.txt 到agentX的/opt/目录。(X为1或2)
(1) 如果托管主机agentX存在/var/news.txt，则不拷贝。
(2) 如果托管主机agentX和agent2不存在/var/news.txt，则不拷贝。
7-2 在 workstation 上创建名为/ansible/playbooks/copyfile.yml, 拷贝来自workstation的/data/school.txt 到agentX的/opt/目录。(X为1或2)
(1) 如果托管主机agentX存在/opt/school.txt，则不拷贝。
(2) 如果托管主机agentX和agent2不存在/opt/school.txt，则不拷贝
- name: copyfile
hosts: webservers
gather_facts: no
tasks:
- name: 1
copy:
src: /data/school.txt
dest: /opt/
force: no
