nfs服务客户端三台主机
centos7 10.0.0.7、centos6 10.0.0.8、centos7 10.0.0.9

判断的格式

1.9 ansible剧本实现nfs一键化部署
第一个历程: 按照模块方式,完成服务每个步骤部署
服务端配置
01. 安装部署软件程序: rpcbind nfs-utile



ansible nfs_server -m yum -a "name=rpcbind state=installed"
ansible nfs_server -m yum -a "name=nfs-utile state=installed"



02. 编写配置文件:配置文件要提前写好


# 批量管理主机写好的配置文件推送给服务端/etc/ansible-playbook/nfs.conf 
ansible nfs_server -m copy -a "src=/etc/ansible/ansible_playbook/nfs.conf dest=/etc/exports"



03. 创建共享目录:


ansible nfs_server -m file -a "path=/data/ state=directory owner=nfsnobody group=nfsnobody"



04. 启动程序服务:


ansible nfs_server -m service -a "name=rpcbind state=started enabled=yes"
ansible nfs_server -m service -a "name=nfs state=started enabled=yes"



客户端配置:
01. 安装部署软件


ansible nfs_client -m yum -a "name=nfs-utile state=installed"



02. 挂载共享目录


ansible nfs_client -m mount -a "src=172.16.1.31:/data/ path=/mnt fstype=nfs state=mounted"



第二个历程编写剧本：


[root@m01 ansible_playbook]#vim nfs_auto.yaml 
- hosts: nfs_server
 tasks:
  - name: 1:install rpcbind nsf-utils
   yum:
    name:
     - rpcbind
     - nfs-utils
    state: installed
  - name: 2:copy conf file
   copy: src=/etc/ansible/ansible_playbook/nfs.conf dest=/etc/exports
  - name: 3:create data dir
   file: path=/data/ state=directory owner=nfsnobody group=nfsnobody
  - name: 4:boot server rcbind
   service: name=rpcbind state=started enabled=yes
  - name: 4:boot server nfs
   service: name=nfs state=restarted enabled=yes
- hosts: nfs_client
 tasks:
  - name: 1:install nfs
   yum: name=nfs-utils state=installed
  - name: 2:mount data dir
   mount: src=172.16.1.31:/data/ path=/mnt fstype=nfs state=mounted



恢复环境剧本


[root@m01 ansible_playbook]#vim nfs_backup.yaml 
- hosts: nfs_server 
 tasks:
  - name: 01:install rpcbind nfs-utils
   yum:
    name:
     - rpcbind
     - nfs-utils
    state: removed
  - name: 02:copy conf file
   shell: echo "" >/etc/exports
  - name: 03:create data dir
   file: path=/data/ state=absent
- hosts: nfs_client
 tasks:
  - name: 01:install nfs
   yum: name=nfs-utils state=removed
  - name: 02:mount data dir
   mount: src=172.16.1.31:/data/ path=/mnt fstype=nfs state=unmounted



优化剧本：


[root@m01 ansible_playbook]#vim nfs_auto.yaml 
- hosts: nfs_server
 vars:
  conf_file: exports
  data_dir: /data
 tasks:
  - name: 01:install nfs rpcbind

    state: installed
  - name: 02:copy conf file

  - name: 03:check mount info
   shell: df -h|grep mnt
   register: mount_info
  - debug: msg={{ mount_info.stdout_lines }}




1.10 ansible剧本实现sersync一键化部署
第一个历程: 按照模块方式,完成服务每个步骤部署配置hosts主机清单


[server_server]
172.16.1.31
[server_client]
172.16.1.41

#安装rsync
ansible backup_server -m yum -a "name=rsync state=installed"
#在批量管理主机上下载sersync，解压发送给客户端
ansible backup_server -m file -a "src=/usr/local/sersync_installdir_64bit/sersync dest=/usr/local"
#在批量管理主机上写好sersync配置文件，发送给客户端
ansible backup_server -m copy -a "src=/usr/local/sersync_installdir_64bit/sersync/conf/confxml.xml dest=/usr/local/sersync/conf/"
#给sersync加上执行权限
ansible backup_server -m file -a "path=/usr/local/sersync/bin/sersync mode=a+x"
#给sersync创建软链接
ansible backup_server -m file -a "src=/usr/local/sersync/bin/sersync path=/usr/local/sbin/sersync state=link"
#启动sersync 测试实时同步
ansible backup_server -m shell -a "sersync -dro /usr/local/sersync/conf/confxml.xml"




第二个历程，编写剧本


[root@m01 ansible_playbook]#vim sersync_auto.yaml 
- hosts: sersync_server
 tasks:
  - name: 安装rsync
   yum: name=rsync state=installed
  - name: 将sersync传输到客户端
   file: src=/usr/local/sersync_installdir_64bit/sersync/ dest=/usr/local
  - name: 将写好的配置文件传输到客户端
   copy: src=/usr/local/sersync_installdir_64bit/sersync/conf/confxml.xml dest=/usr/local/sersync/conf/
  - name: 加上执行权限
   file: path=/usr/local/sersync/bin/sersync mode=a+x
  - name: 创建软链接

  - name: 启动sersync 测试实时同步
   shell: sersync -dro /usr/local/sersync/conf/confxml.xml



恢复环境剧本


[root@m01 ansible_playbook]#cat sersync_backup.yaml
- hosts: sersync_server
 tasks:
  - name: 卸载rsync 
   yum: name=rsync state=removed
  - name: 删除sersync
   file: path=/usr/local/sersync




2 多个剧本如何进行整合
第一个历程: 确保每个剧本执行成功第二个历程: 进行剧本整合方法一：不建议使用


[root@m01 ansible_playbook]#vim zhenghe.yaml # ---角色里使用
- hosts: all
 remote_user: root
 tasks:
  - include_tasks: nfs_auto.yml
  - include_tasks: rsync_auto.yml
# 不写hosts信息，只写任务信息



方法二：在以后的ansible中可能会取消include功能


[root@m01 ansible_playbook]#vim zhenghe.yaml 
- include：nfs_auto.yml 
- include：rsync_auto.yml



方法三：建议使用这个方法


[root@m01 ansible_playbook]#vim zhenghe.yaml 
- import_playbook: nfs_auto.yaml   
- import_playbook: rsync_auto.yaml




3 ansible剧本编写方式：角色
（1）规范ansible程序目录结构（2）汇总剧本中有定义的主机信息
3.1 角色调用流程图

3.2 nfs服务角色编写
第一个历程: 创建角色目录结构


cd roles/;mkdir {nfs,rsync,web,sersync} 
cd nfs/{vars,tasks,templates,handlers,files}
# vars:   定义变量信息
# tasks:   定义任务信息
# templates: 定义模板文件(jinja2模板文件)
# handlers: 定义触发器信息
# files:   定义需要分发的文件



第二个历程: 编写文件信息 tasks: 任务信息编写方式一: nfs服务编写


vim main.yaml
- name: 01:install nfs rpcbind
 yum:
  name: ['nfs-utils', 'rpcbind'] 
  state: installed
- name: 02:copy conf file
 copy: src=/etc/ansible/ansible_playbook/nfs.conf dest=/etc/{{ conf_file }}
 notify: 
  - nfs_restart
- name: 03:create data dir 
 file: path={{ data_dir }} state=directory owner=nfsnobody group=nfsnobody
- name: 04:boot server rpcbind
 service: name={{ item.name }} state={{ item.state }} enabled={{ item.enabled }}
 with_items:
  - {name: "rpcbind", state: "started", enabled: "yes"}
  - {name: "nfs",   state: "started", enabled: "yes"}
- name: 01:install nfs
 yum: name=nfs-utils state=installed
- name: 02:mount data dir
 mount: src=172.16.1.31:{{ data_dir }} path=/mnt fstype=nfs state=mounted
- name: 03:check mount info
 shell: df -h|grep mnt
 register: mount_info
- debug: msg={{ mount_info.stdout_lines }}



tasks: 任务信息编写方式二: tasks：定义任务信息


cd tasks
vim main.yaml
vim nfs_boot.yaml
vim nfs_conf.yaml
vim nfs_datadir.yaml
vim nfs_install.yaml
vim nfs_mount.yaml
#########################
vim main.yaml
- include_tasks: nfs_install.yaml
- include_tasks: nfs_conf.yaml
- include_tasks: nfs_datadir.yaml
- include_tasks: nfs_boot.yaml
- include_tasks: nfs_mount.yaml



vars：定义变量信息


vim main.yaml
conf_file: exports
data_dir: /data



files：定义需要分发的文件


[root@m01 files]# ll
total 4
-rw-r--r-- 1 root root 42 Jul 29 10:34 nfs.conf



handlers：定义触发器信息


vim main.yaml 
- name: nfs_restart
service: name=nfs state=reloaded
