管理配置文件

1.cd /etc/ansible;mkdir nginx_config

2.cd nginx_config;mkdir roles;cd roles;

3.mkdir old new;cd new/

4.mkdir vars files tasks handlers

5.将配置文件拷贝到对应的 files下

cp /usr/local/nginx/conf/nginx.conf files/

cp -r /usr/local/nginx/conf/vhosts files/

6.定义变量

# vim vars/main.yml

nginx_basedir: /usr/local/nginx

7.定义 handlers

# vim handlers/main.yml

- name: restart nginx

  shell: /etc/init.d/nginx reload

8.定义 tasks

# vim tasks/main.yml

- name: copy conf file

  copy: src={{ item.src }} dest={{ nginx_basedir }}/{{ item.dest }} backup=yes owner=root group=root mode=0644

  with_items:

    - { src: nginx.conf, dest: conf/nginx.conf }

    - { src: vhosts, dest: conf/ }

  notify: restart nginx

9.定义总的入口文件

# vim update.yml

---

- hosts: 192.168.32.105

  user: root

  roles:

    - new

10.vi /etc/ansible/nginx_config/roles/new/files/vhosts/1.conf

# sahdusah

11.vim /etc/ansible/nginx_config/roles/new/files/nginx.conf

 include vhosts/*.conf

11.发布

ansible-playbook update.yml

回滚

rsync -av new/files/ old/files/

# vim backup.yml

---

- hosts: 192.168.32.105

  user: root
