思路：

niginx

1.group:nginx

2.user:nginx

3.yum:nginx

4.template:nigin.conf.j2

5.service:nginx

目录结构如下：

cd nginx

mkdir tasks templates

cd tasks

vim group.yml

– name: create group

group: name=nginx gid=80

vim user.yml

– name: create user

user: name=nginx group=nginx uid=80 shell=/sbin/noligin

vim yum.yml

– name: install package

yum: name=nginx

vim start.yml

– name: start service

service: name=nginx state=started enabled=yes

vim restart.yml

– name: restart service

service: name=nginx state=restarted

cp /etc/nginx/nginx.conf template/nginx.conf.j2

vim template/nginx.conf.j2

worker_processes {{ ansible_processes_vcpus+2 }};

vim templ.yml

– name: copy conf

template: src=nginx.conf.j2 dest=/etc/nginx/nginx.conf

vim main.yml

– include: group.yml

– include: user.yml

– include: yum.yml

– include: templ.yml

– include: start.yml

调用角色的剧本要和roles目录在同一文件夹

vim nginx_roles.yml

– hosts: websrvs

romete_user: root

roles:

– role: nginx

ansible-playbook -C nginx_role.yml

执行结果如下：
