Ansible Roles编排实现Httpd角色的部署

设置SSH免密码登陆
vim ansible_ssh.sh
#!/bin/bash
[ -f ~/.ssh/id_rsa ] || ssh-keygen -f ~/.ssh/id_rsa -P "" -q
rpm -q sshpass &> /dev/null || yum -y install sshpass &> /dev/null
prefix=10.0.0.
passwd=tianze

for i in {12..13};do
{
    sshpass -p $passwd ssh-copy-id -o StrictHostKeyChecking=no -i ~/.ssh/id_rsa root@$prefix$i &> /dev/null
}&
done
wait

bash ansible_ssh.sh
安装ansible
yum -y install ansible  ##事先需要配置好epel源  
vim /etc/ansible/hosts  ##文件末尾添加以下内容 主机清单
[webservers]  ##主机组
10.0.0.8

10.0.0.18

创建角色相关的目录： 

mkdir -pv 、/data/ansible/roles/httpd/{tasks,handlers,files}

创建角色相关的文件：

cd /data/ansible/roles/httpd/

main.yml是task的入口文件

[root@centos8-1 httpd]$vim tasks/main.yml
- include: group.yml
- include: user.yml
- include: install.yml
- include: config.yml
- include: index.yml
- include: service.ym

[root@centos8-1 httpd]$vim tasks/group.yml
- name:create group
group: name=apache system=yes gid=80

[root@centos8-1 httpd]$vim tasks/user.yml

- name: create apache user
user: name=apache system=yes shell=/sbin/nologin home=/var/www/ uid=80 group=apache

[root@centos8-1 httpd]$vim tasks/install.yml

- name: install httpd package
yum: name=httpd

[root@centos8-1 httpd]$vim tasks/config.yml

- name: config file
copy: src=httpd.conf dest=/etc/httpd/conf/ backup=yes
notify: restart

root@centos8-1 httpd]$vim tasks/index.yml

- name: index.html
copy: src=index.html dest=/var/www/html/

[root@centos8-1 httpd]$vim tasks/service.yml

- name: start service
service: name=httpd state=started enabled=yes

[root@centos8-1 httpd]$vim handlers/main.yml

- name: restart
service: name=httpd state=restarted

在files目录下准备两个文件（可也用yum -y install httpd安装后把文件copy到files目录下）

[root@centos8-1 ansible]$ls files/
httpd.conf index.html

yum -y install httpd

[root@centos8-1 ansible]$cp /etc/httpd/conf/httpd.conf /roles/httpd/files/

[root@centos8-1 ansible]$echo The is httpd based roles > /roles/httpd/files/index.html

[root@centos8-1 ansible]$tree /data/ansible/roles/httpd/
/data/ansible/roles/httpd/
├── files
│   ├── httpd.conf
│   └── index.html
├── handlers
│   └── main.yml
└── tasks
├── config.yml
├── group.yml

3 directories, 10 files

在playbook中调用角色

[root@centos8-1 ansible]$vim /data/ansible/role_httpd.yml

---
- hosts: db
remote_user: root

roles:
- httpd

运行playbook

[root@centos8-1 ansible]$ansible-playbook /data/ansible/role_httpd.yml
