详解ansible批量管理服务

1 ansible-playbook 任务剧本

1.1 剧本文件概念

(1)playbook可以将多个批量操作模块功能整合,完成一件事情。(2)简化运维工作复杂度(3)playbook通过yaml语法识别描述的状态文件,扩展名是yaml

1.2 剧本文件组成部分

(1)剧本的角色(hosts)定义的是主机信息(2)剧本的任务(tasks)定义的是具体任务信息(3)一个剧本文件有多个hosts组成,一个hosts可以包含多个tasks任务

1.3 剧本文件优势特点

(1)实现自动化功能更加全面(2)可以更好的控制逻辑关系(3)剧本展现命令语法更直观(4)拥有持久反复执行的特性

1.4 剧本文件编写规范

(1)缩进特点: 两个空格表示一个缩进关系(2)冒号用法: 冒号后面需要有空格 冒号结尾不需要有空格主机信息: 172.16.1.41 --- key: value (键值写法) (3)列表用法: 利用短横线加空格构建列表清单

1.5 剧本执行使用方法

(1)检查剧本语法:ansible-playbook --syntax-check test.yaml (2)剧本模拟执行:ansible-playbook -C test.yaml (3)剧本真实运行:ansible-playbook test.yaml

1.6 剧本编写扩展功能

(1)剧本变量编写功能(2)剧本信息通知功能(3)剧本信息判断功能(4)剧本信息循环功能(5)剧本编写忽略错误(6)剧本标签设置功能(7)剧本忽略采集功能(8)剧本信息触发功能

1.6.1 剧本变量编写功能

设置变量方法一: 在剧本执行命令参数中设置变量,命令行最优先

[root@m01 ansible_playbook]#ansible-playbook -e dir=/etc -e file=rsyncd.conf test_变量编写.yaml

设置变量方法二: 在剧本中设置变量,剧本变量其次优先

[root@m01 ansible_playbook]#vim test_变量编写.yaml 
- hosts: 172.16.1.41
 vars:
 dir: /etc
 file: rsyncd.conf
 tasks:
 - name: copy file 
  copy: src={{ dir }}/{{ file }} dest={{ dir }}/
# {{}}调用变量

设置变量方法二: 在主机清单中设置变量,主机清单变量最不优先

[root@m01 ansible_playbook]#vim /etc/ansible/hosts
[sersync_server]
172.16.1.31
[sersync_client]
172.16.1.41
[sersync_server:vars]
dir=/etc
file=rsyncd.conf
# 直接给主机组设置变量,这样主机组内的所有主机都可以调用变量了

1.6.2 剧本信息通知功能

编辑剧本

[root@m01 ansible_playbook]#vim test_通知功能.yaml
- hosts: 172.16.1.41
 tasks:
 - name: boot server
  service: name=rsyncd state=started
 - name: check server boot
  shell: netstat -lntup|grep 873
  register: oldboy
 - debug: msg={{ oldboy.stdout_lines }}
# 将shell中命令执行结果通过register注册给oldboy,oldboy相当于一个变量,{{}}调取oldboy
# debug类似echo,输出信息
# stdout_lines 将输出的信息变得有格式

运行剧本

[root@m01 ansible_playbook]#ansible-playbook test_通知功能.yaml

  "tcp6  0  0 :::873     :::*     LISTEN  3708/rsync   "
 ]
}

PLAY RECAP *******************************************************************************************
172.16.1.41    : ok=4 changed=1 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0 

1.6.3 剧本信息判断功能

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
此时在批量启动的时候需要进行判断,因为centos6,centos7启动命令不一样
判断的格式
- hosts: nfs_client
tasks:
- name: boot centos7 nfs
shell: systemctl start nfs 
判断: 如果是centos7 "filter=ansible_hostname"
172.16.1.41 | SUCCESS => {
 "ansible_facts": {
  "ansible_hostname": "backup", 
  "discovered_interpreter_python": "/usr/bin/python"
 }, 
 "changed": false
}

# filter 过滤 筛选

实现收集子信息的方法

问题: 获取主机信息,以及子信息

方法一:

- hosts: rsync
 tasks:
 - name: touch file
  file: path=/etc/oldboy01.txt state=touch
  when: (ansible_eth1.ipv4.address == "172.16.1.41")

方法二:

- hosts: rsync
 tasks:
 - name: touch file
  file: path=/etc/oldboy01.txt state=touch
  when: (ansible_eth1["ipv4"]["address"] == "172.16.1.41")

setup模块常用来收集的信息

详解ansible批量管理服务

根据 ip 地址进行判断创建目录

[root@m01 ansible_playbook]#vim test_判断功能.yaml
- hosts: nfs_client
 tasks:
 - name: create file for 41 host
  file: path=/tmp/172.16.1.41 state=directory
  when: (ansible_hostname == "backup")
 - name: create file for 7 host
  file: path=/tmp/172.16.1.7 state=directory
  when: (ansible_hostname == "web01")

运行剧本

root@m01 ansible_playbook]#ansible-playbook -C test_判断功能.yaml 

PLAY [nfs_client] ************************************************************************************

TASK [Gathering Facts] *******************************************************************************
ok: [172.16.1.41]
ok: [172.16.1.7]

TASK [create file for 41 host] ***********************************************************************
skipping: [172.16.1.7]
changed: [172.16.1.41]

TASK [create file for 7 host] ************************************************************************
skipping: [172.16.1.41]
changed: [172.16.1.7]

PLAY RECAP *******************************************************************************************
172.16.1.41    : ok=2 changed=1 unreachable=0 failed=0 skipped=1 rescued=0 ignored=0 
172.16.1.7     : ok=2 changed=1 unreachable=0 failed=0 skipped=1 rescued=0 ignored=0 

1.6.4 剧本信息循环功能

循环创建多个用户

[root@m01 ansible_playbook]#vim test_循环功能.yaml
- hosts: 172.16.1.41
 tasks:
 - name: create user
  user: name={{ item }}
  with_items:
  - oldgirl01
  - oldgirl02
  - oldgirl03
  - oldgirl04
  - oldgirl05

循环创建多个用户 多个用户uid数值是不同的

[root@m01 ansible_playbook]#vim test_循环功能.yaml
- hosts: 172.16.1.41
 tasks:
 - name: create user
  user: name={{ item.name }} uid={{ item.uid }}
  with_items:
  - {name: "oldgirl06", uid: "3006"}
  - {name: "oldgirl07", uid: "3007"}
  - {name: "oldgirl08", uid: "3008"}
  - {name: "oldgirl09", uid: "3009"}
  - name: check create user info
   shell: grep oldgirl0 /etc/passwd
   register: user_info
  - debug: msg={{ user_info.stdout_lines }}

1.6.5 剧本编写忽略错误功能

忽略功能主要用来调试剧本

[root@m01 ansible_playbook]#vim test_h忽略功能.yaml
- hosts: 172.16.1.41
 tasks:
 - name: create rsync user
  shell: useradd rsync -M -s /sbin/nologin
  ignore_errors: yes
 - name: create backup dir
  shell: mkdir /backup
  ignore_errors: yes
 - name: boot server
  shell: systemctl start rsyncd
  ignore_errors: yes

在使用shell进行一些操作时,shell产生的结果已经存在时,会导致剧本无法进行下去,因此使用忽略功能可以有效的使剧本进行下去。

1.6.6 剧本标签设置功能

标签功能主要用来调试剧本

tags:标签

[root@m01 ansible_playbook]#vim test_标签功能.yaml
- hosts: 172.16.1.41
 tasks:
 - name: 01:安装软件
  yum: name=rsync state=installed
  ignore_errors: yes
 - name: 02:创建用户
  user: name=rsync create_home=no shell=/sbin/nologin
  ignore_errors: yes
  tags: create_user
 - name: 03:创建目录
  file: path=/backup state=directory

运行剧本

ansible-playbook -t create_user test_标签功能.yaml    --- 执行剧本中标签任务
ansible-playbook --skip-tags create_user test_标签功能.yaml --- 跳过指定标签任务,执行其他任务
ansible-playbook -t create_user,create_dir test_标签功能.yaml --- 执行多个标签
# -t=tags

1.6.7 剧本忽略采集功能

[

root@m01 ansible_playbook]#vim test_忽略采集.yaml
- hosts: 172.16.1.41
 gather_facts: no
 tasks:
 - name: 01:安装软件
  yum: name=rsync state=installed
  ignore_errors: yes
 - name: 02:创建用户
  user: name=rsync create_home=no shell=/sbin/nologin
  ignore_errors: yes
  tags: create_user
 - name: 03:创建目录
  file: path=/backup state=directory
  tags: create_dir 

当剧本采集大量主机信息时,可能会变得卡,慢,影响剧本后面的操作执行的效率。所以在这个时候,可以忽略采集功能,提高效率,在hosts下面添加 gather_facts: no 如果剧本中有判断功能,不能使用此参数,因为采集的信息会与判读信息对比

1.6.8 剧本信息触发功能

编写剧本

[root@m01 ansible_playbook]#vim test_触发功能.yaml
- hosts: 172.16.1.41
 tasks:
 - name: 01:传输配置文件
  copy: src=/etc/ansible/ansible_playbook/rsyncd.conf dest=/etc/
  notify: rsync_restart
 - name: 02:启动服务程序
  service: name=rsyncd state=started
 handlers:
 - name: rsync_restart
  service: name=rsyncd state=restarted

handlers:一般用于配置文件修改时,才会进行触发功能,对服务进行重启 notify:传输配置文件过来,notify通知rsync_restart这个触发器。然后handlers会进行重启服务说明: 整体任务执行完毕,才会执行触发功能

1.7 编写剧本练习题

要求:

(1)在172.16.1.41主机上操作: ①将定时任务服务停止 ②创建一个/etc/目录软连接 在/opt目录中生成 ③将本地/etc/hosts文件分发给41主机 保存到/tmp目录中(2)在172.16.1.31主机上操作: ①将防火墙服务开机自动运行 ②将主机上安装keepalived软件

实践:

编写剧本文件

[root@m01 ansible_playbook]#vim test.yaml 
- hosts: 172.16.1.41
 tasks:
 - service: name=crond state=stopped
 - file: src=/etc path=/opt/etc_link state=link
 - copy: src=/etc/hosts dest=/tmp
- hosts: 172.16.1.31
 tasks:
 - service: name=firewalld enabled=yes
 - yum: name=keepalived state=installed

剧本语法检查

# 语法检查剧本文件
[root@m01 ansible_playbook]#ansible-playbook --syntax-check test.yaml 
playbook: test.yaml

剧本模拟执行

[root@m01 ansible_playbook]#ansible-playbook -C test.yaml

补充:

如果系统中装有cowsay软件,在执行命令时,会产生图案信息,影响查阅结果,可以关闭。

[root@m01 ansible]#vim ansible.cfg 
# don't like cows"htmlcode">
# 安装软件程序
ansible rsync -m yum -a "name=rsync state=installed"
# 编写配置文件:要在批量管理主机上提前写好,然后推送给服务端
# 在管理端准备好服务配置文件
ansible rsync_server -m copy -a "src=/etc/ansible/conf_file/rsyncd.conf dest=/etc/"
# 创建虚拟用户
ansible rsync_server -m user -a "name=rsync create_home=no shell=/sbin/nologin"
# 创建密码文件 (授权600)
ansible rsync_server -m copy -a "content='rsync_backup:oldboy123' dest=/etc/rsync.password mode=600"
# 创建备份目录 (授权 属主 属组)
ansible rsync_server -m file -a "path=/backup state=directory owner=rsync group=rsync"
@ 启动程序服务
ansible rsync_server -m service -a "name=rsyncd state=started enabled=yes"

第二步:客户端配置

# 创建密钥文件 (授权600)
ansible rsync_client -m copy -a "content='oldboy123' dest=/etc/rsync.password mode=600"
# 批量测试传输文件
ansible rsync_client -m shell -a "rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup --password-file=/etc/rsync.password"

第二个历程: 编写剧本信息

- hosts: rsync_server
 tasks:
  - name: 01:install rsync
   yum: name=rsync state=installed
  - name: 02:copy conf file
   copy: src=/etc/ansible/conf_file/rsyncd.conf dest=/etc/
  - name: 03:create rsync user

  - name: 05:create backup dir
   file: path=/backup state=directory owner=rsync group=rsync
  - name: 06:boot rsync server
   service: name=rsyncd state=started enabled=yes

- hosts: rsync_client
 tasks:
  - name: 01:create password file
   copy: content='oldboy123' dest=/etc/rsync.password mode=600

  - name: 04:delete backup dir
   file: path=/backup/ state=absent
  - name: 05:boot rsync server
   service: name=rsyncd state=stopped enabled=no

- hosts: rsync_client
 tasks:
  - name: 01:delete password file
   file: path=/etc/rsync.password state=absent

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

  - 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 }}

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

- hosts: sersync_server
 tasks:
  - name: 安装rsync
   yum: name=rsync state=installed
  - name: 将sersync传输到客户端

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

详解ansible批量管理服务

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
