ansible playbook:剧本
由一个或多个模块组成，完成统一的目的，实现自动化操作
剧本编写遵循yaml语法
yaml的三要素：
缩进：两个字符，默认的tab键是四个字符，所以要使用tab键，需要修改.vimrc
vim /root/.vimrc
添加：
set tabstop=2
保存退出
冒号：冒号后面需要空格，除非以冒号结尾
短横杠：列表项，后面跟空格
playbook语法结构
ansible-playbook 选项 文件路径
选项：
-C 模拟预运行
--list-hosts:列出清单
--list-tasks:列出任务
--list-tags:列出标签
--syntax-check:语法检查
测试案例：通过playbook安装httpd,并修改端口号为8080
前提：安装httpd，复制httpd.conf到当前目录，修改端口为8080
vim httpd.yaml
添加：
- hosts: web
tasks:
- name: install httpd
yum: name=httpd state=latest
- name: httpd config
copy: src=httpd.conf dest=/etc/httpd/conf/httpd.conf
notify: restart httpd
- name: start httpd
service: name=httpd state=started
handlers:
- name: restart httpd
service: name=httpd state=restarted
保存退出
测试yaml: ansible-playbook -C httpd.yaml
执行yaml：ansible-playbook httpd.yaml

playbook配置web--nfs--rsync架构环境
全局环境：修改各主机名：ansible、web、nfs、rsync
1.服务器配置
前提：
ifdown ens33;ifup ens33
systemctl stop firewalld
systemctl disable firewalld
setenforce 0
vim /etc/hosts
192.168.8.10 ansible
192.168.8.20 web
192.168.8.30 nfs
192.168.8.40 rsync
保存退出
（1）安装ansible
yum -y install epel-release
yum -y install ansible
（2）ssh公钥
ssh-keygen -t rsa
ssh-copy-id root@web #web服务器
ssh-copy-id root@nfs #nfs服务器
ssh-copy-id root@rsync #rsync服务器
（3）复制/etc/hosts到被管理端
scp /etc/hosts root@web:/etc/
scp /etc/hosts root@nfs:/etc/
scp /etc/hosts root@rsync:/etc/
（4）创建ansible目录
mkdir -p /etc/ansible/ansible_playbook/{conf,file,scripts,tools}
（5）创建ansible清单
vim /etc/ansible/hosts
添加：
[web]
192.168.8.20
[nfs]
192.168.8.30
[rsync]
192.168.8.40
保存退出
（6）使用ansible copy 复制/etc/hosts到所有主机
ansible all -m copy -a "src=/etc/hosts dest=/etc"
2.基础环境部署
（1）网络环境（关闭firewall selinux）
（2）epel仓库
（3）安装rsync，nfs-utils
（4）创建组
（5）创建用户
（6）创建目录，并修改权限
（7）推送脚本
（8）推送rsync客户端密码文件，修改权限
（9）计划任务
vim /etc/ansible/ansible_playbook/base.yaml
添加：
- hosts: all
tasks:
- name: stop firewalld
shell: systemctl stop firewalld
- name: stop selinux
shell: setenforce 0
- name: clear repos.d
file: path=/etc/yum.repos.d/ state=absent
- name: create repos.d
file: path=/etc/yum.repos.d/ state=directory
- name: install base repo
get_url: url=http://mirrors.aliyun.com/repo/Centos-7.repo dest=/etc/yum.repos.d/CentOS-Base.repo
- name: install epel repo
get_url: url=http://mirrors.aliyun.com/repo/epel-7.repo dest=/etc/yum.repos.d/epel.repo
- name: install rsync nfs-utils
yum: name=rsync,nfs-utils state=installed
- name: create group www
group: name=www gid=666
- name: create user www
user: name=www uid=666 create_home=no shell=/sbin/nologin
- name: create rsync client password
copy: content='1' dest=/etc/rsync.pass mode=600
- name: create scripts directory
file: path=/server/scripts/ recurse=yes state=directory
- name: push scripts
copy: src=./scripts/rsync_backup.sh dest=/server/scripts
- name: crontab
cron: name="backup scripts" hour=01 minute=00 job="/usr/bin/bash /server/scripts/rsync_backup.sh &> /dev/null"
保存退出
3.rsync配置

yum: name=rsync state=installed
- name: config rsync
copy: src=/etc/ansible/ansible_playbook/conf/rsyncd.conf dest=/etc/rsyncd.conf
