mount

mount挂载

环境准备

主机名	安装服务	wan	lan
web01	nfs客户端	10.0.0.7	172.16.1.7
web02	nfs客户端	10.0.0.8	172.16.1.8
nfs	nfs服务端	10.0.0.9	172.16.1.9

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.查看nfs客户端是否启动
	2.挂载

创建角色

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

编辑tasks目录

1.检查nfs服务端
[root@m01 mount_server]# vim tasks/check.yml
- name: check server nfs
  shell: "ps -ef|grep [n]fs"
  ignore_errors: yes
  register: check_nfs

- name: start nfs
  service:
    name: nfs
    state: started
  when: {{ check_nfs }}.rc != 0
2.编辑include
[root@m01 mount_server]# vim tasks/main.yml 
- include: check.yml

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*' }
    #- { role: nfs_client,when: ansible_fqdn is match 'web*' }
    - { role: mount_server,when: ansible_fqdn is match 'nfs*' }

执行

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

注意

1.mount模块不支持列表,一个动作对应多个值的时候可以考虑使用循环（with_items loop）
with_item中不支持变量。loop中可以再次使用变量
