用roles部署nginx

1、初始化一个role

[root@bogon ~]# ansible-galaxy init /etc/ansible/roles/websrvs

查看已经创建的role

[root@bogon ~]# ls /etc/ansible/roles/

webservs

2、配置role

把初始化后 role里面没用的删除，只留下面四个目录

[root@bogon ~]# cd /etc/ansible/roles/webservs/

[root@bogon webservs]# ls

handlers  README.md  tasks  templates  vars

[root@bogon webservs]# ls templates/

index.html.j2  nginx.conf.j2

配置变量vars

[root@bogon webservs]# cat vars/main.yml

---

# vars file for /etc/ansible/roles/webservs

worker_processes: 4

worker_connections: 768

max_open_files: 65506

tasks 文件内容

[root@bogon webservs]# cat tasks/main.yml

---

# tasks file for /etc/ansible/roles/webservs

- name: install nginx

  command: yum install nginx -y

- name: copy nginx config file

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

  notify: restart nginx

- name: copy index.html

  template:

    src: index.html.j2

    dest: /usr/share/nginx/www/index.html

    mode: 0644

  notify: restart nginx

- name: see file

  command: ls /root

  notify: restart nginx

handlers 文件内容：

[root@bogon webservs]# cat handlers/main.yml

---

# handlers file for /etc/ansible/roles/webservs

- name: restart nginx

  service: name=nginx state=restarted

模板文化内容：

[root@bogon webservs]# cat templates/nginx.conf.j2

worker_processes {{ worker_processes }};

worker_rlimit_nofile {{ max_open_files }};

events {

    worker_connections {{ worker_connections }};

}

http {

    server {

        listen       80;

        root  /usr/share/nginx/www;

        index index.html index.htm default.html index.php;

        server_name loclhost;

        location / {

            try_files  / =404;

        }

    }

}

[root@bogon webservs]# cat templates/index.html.j2

<html>

  <head>

    <title>welcome to american</title>

  </head>

  <body>

  <h1>nginx, confitured by ansible</h1>

  <p>if you can see this, ansible successfully installed nginx.</p>

  <p>{{ ansible_hostname }}</p>

  </body>

</html>

3、配置playbook，把role添加进来

[root@bogon ~]# cat nginx_role.yaml

---

- hosts: webservers

  become: yes

  become_method: sudo

  roles:

    - role: webservs

4、开始执行Playbook

[root@bogon ~]# ansible-playbook nginx_role.yaml
