playbook配置nfs服务

server	192.168.83.10	mater
client1	192.168.83.11	node1
client2	192.168.83.12	node2

配置文件	/ansible/files/exports ------/etc/exports
分享目录	/ansible_data
挂载目录	/mnt/nfs

1、配置主机资产清单

master
[dev]
master
[test]
192.168.83.1[1:2]
[prod]
node2
[Webserver:children]
prod
[slb:children]
dev
test

测试三台主机是否联通：

[root@master ansible]# ansible -i inventory all -m ping

2、nfs-server实现功能

（1）安装nfs 

（2）配置nfs

（3）创建组

（4）创建用户

（5）设置分享目录

（6）启动服务

（7）设置防火墙规则

[root@master ansible]# vim nfs_server.yml

- hosts: test
  gather_facts: False #不执行setup模块获取主机相关信息
  tasks:
  - name: 1. Install nfs Server
    yum:
      name: nfs-utils
      state: present #状态为立即执行

  - name: 2.  Configure nfs Server
    copy:
      src: ./files/exports
      dest: /etc/exports
      backup: yes   #备份

  - name: 3. Creat nfs group
    group:
      name:  iii
      gid: 222

  - name: 4. Create nfs user
    user:
      name: jjj
      uid: 333
      create_home: no #不创建用户家目录
      shell: /sbin/nologin #不设置系统交互的shell，不能登陆

  - name: 5. Create nfs share directory
    file:
      path: /ansible_data
      owner: jjj
      group: iii
      mode: '0775'
      recurse: yes  #设置递归
      state: directory

  - name: 6. Start nfs server
    service:
      name: nfs-server
      state: started
      enabled: yes   #开机自启动

  - name: 7. Modify firewall rule
    firewalld:
      service: "{{ item }}"
      permanent: yes
      state: enabled
      immediate: yes
    with_items:
      - nfs
      - rpc-bind
      - mountd

检测语法：

[root@master ansible]# ansible-playbook nfs_server.yml --syntax-check
 [WARNING]: Could not match supplied host pattern, ignoring: nfs


playbook: nfs_server.yml

正式运行：

[root@master ansible]# ansible-playbook nfs_server.yml

配置nfs文件：

[root@master ansible]# cat files/exports

3、nfs-client实现功能

（1）安装nfs客户端

（2）设置挂载目录

（3）挂载

---
- hosts: prod
  tasks:
    - name: 1. Insatall nfs-utils
      yum:
        name: nfs-utils
        state: present

    - name: 2. Mount point
      file:
        path: /mnt/nfs
        state: directory

    - name: 3. Mount nfs
      mount:
        src: node2:/ansible_data
        path : /mnt/nfs
        fstype: nfs        #文件类型
        state: mounted     #mounted开机自动挂载 present临时挂载

检测语法：

[root@master ansible]# ansible-playbook nfs_client.yml  --syntax-check

playbook: nfs_client.yml
[root@master ansible]# ansible-playbook nfs_client.yml  --list-hosts

playbook: nfs_client.yml

  play #1 (prod): prod	TAGS: []
    pattern: ['prod']
    hosts (1):
      node2

正式运行：

[root@master ansible]# ansible-playbook nfs_client.yml 

PLAY [prod] ********************************************************************************

TASK [Gathering Facts] *********************************************************************
ok: [node2]

TASK [1. Insatall nfs-utils] ***************************************************************

在node2上检测：

[root@node2 ~]# df -h
