Ansible的roles功能（五）
针对大型项目使用Roles进行编排，更便利目录结构编排
一键安装httpd并提供服务
创建目录结构
# mkdir -p roles/httpd/{tasks,files,vars}
# cd roles/httpd/tasks
#touch httpd/{files/main.yml,tasks/{groupadd.yml,install.yml,main.yml,restart.yml,useradd.yml},vars/main.yml}
目录结构创建好了，接下来开始配置
# cd /root/ansible/roles/httpd/tasks
首先配置main.yml将所有的配置全部包含进来
# cat main.yml
---
- include: groupadd.yml
- include: useradd.yml
- include: install.yml
- include: restart.yml
配置添加用户组
# cat groupadd.yml
---
- name: add group httpd
group: name=web state=present
配置添加用户
# cat useradd.yml
---
- name: add group httpd
user: name=httpd groups=web system=yes state=present
配置安装httpd
# cat install.yml
---
- name: Install Httpd
yum: name=httpd state=present
配置restart httpd
# cat restart.yml
---
- name: Restart Httpd
service: name=httpd state=restarted
配置主yml文件
# pwd
/root/ansible/roles
# cat installhttpd.yml
---
- hosts: test
remote_user: root
roles:
- role: httpd
测试
提供配置网站文件
# pwd
/root/ansible/roles/httpd/files
# cat index.html
<h1> test </h1>
创建copy模块的文件
# cat filecp.yml
---
- name: Cp DocumentFile
copy: src=index.html dest=/var/www/html/index.html
将文件包含至main
# cat main.yml
---
- include: groupadd.yml
- include: useradd.yml
- include: install.yml
- include: restart.yml
- include: filecp.yml
测试：
roles还可以引用
例：
# pwd
/root/ansible/roles
# cp httpd/ nginx -rf
# cd nginx/tasks/
# rm -rf *
# cd nginx/tasks/
# cat main.yml
---
- include: httpd/tasks/restart.yml
# cp installhttpd.yml installnginx.yml
# cat installnginx.yml
---
- hosts: test
remote_user: root
roles:
- role: nginx
测试：
拓展：
1、一次性执行多个roles
2、对roles进行打标签，可单独执行
测试
3、多重标签
执行web项目
