流程分析

1.安装ansible
2.优化ansible
3.推送公钥
4.开启防火墙
5.开启80 443 873 nfs等端口和服务白名单
6.关闭selinux
7.创建同一的用户

    1.安装nfs-utils
    2.拷贝nfs配置文件
    3.创建共享目录
    4.启动nfs服务端
    	1.在nfs服务端安装sersync
    	2.拷贝sersync配置文件到nfs服务端
    	3.nfs服务端配置rsync密码文件
    	4.启动sersync

nfs配置文件

{% for i in nfs_data_dir %}
/data/{{ i }} 172.16.1.0/24(rw,sync,all_squash,anonuid=666,anongid=666)
{% endfor %}

#可以对nfs_data_dir定义多个值
#nfs_data_dir这个位置可以是变量·数组·range()
参考bash循环
pp="1 11 88 44 00"
for n in $pp;do
	echo "${n}"
done

使用ansible-galaxy命令创建角色目录

[root@m01 roles]# ansible-galaxy init nfs_server

编辑tasks目录

1.安装
[root@m01 nfs_server]# vim tasks/install.yml 
- name: Install nfs-utils
  yum:
    name: "{{ item }}"
    state: present
  loop:
    - nfs-utils
2.创建目录
[root@m01 nfs_server]# vim tasks/dir.yml 
- name: Create Directory
  file:
    path: "{{ item }}"
    state: directory
    owner: "{{ ww_w }}"
    group: "{{ ww_w }}"
    mode: 0755
    recurse: yes
  loop:
    - "{{ nfs_data_dir }}"
3.copy配置文件
[root@m01 nfs_server]# vim tasks/config.yml 
- name: content NFS Server
  template:
    src: exports.j2
    dest: /etc/exports
    owner: root
    group: root
    mode: 0644
  notify:
        - restart nfs
4.启动
[root@m01 nfs_server]# vim tasks/start.yml 
- name: start nfs
  service:
    name: nfs
    state: started
    enabled: yes
5.编辑main.yml
[root@m01 nfs_server]# vim tasks/main.yml 
- include: install.yml
- include: dir.yml
- include: config.yml
- include: start.yml
6.触发器
[root@m01 nfs_server]# vim handlers/main.yml 
- name: restart nfs
  systemd:
    name: nfs-server
    state: restarted
    enabled: yes
7.编辑jinjia模板
[root@m01 nfs_server]# vim templates/exports.j2 
{% for i in nfs_data_dir %}
{{ i }} 172.16.1.0/24(rw,sync,all_squash,anonuid=666,anongid=666)
{% endfor %}
8.变量
[root@m01 nfs_server]# vim vars/main.yml 
#nfs服务端被挂载的目录
nfs_data_dir:
  - "/data"
  - "/data/wowdpress"
  - "/data/WeCenter"
#统一的用户
ww_w: www

编辑入口文件

[root@m01 roles]# vim site.yml 
- hosts: all
  roles:
    #- { role: base }
    #- { role: rsync_client,when: ansible_fqdn is match 'web*' }
    #- { role: rsync_client,when: ansible_fqdn is match 'nfs*' }
    #- { role: rsync_server,when: ansible_fqdn is match 'backup*' }
    - { role: nfs_server,when: ansible_fqdn is match 'nfs*' }

执行

[root@m01 roles]# ansible-playbook site.yml
