Deploying Nginx with Ansible Playbooks

Playbooks Overview Ansible playbooks are a flexible, YAML‑based configuration management and multi‑host deployment system that allows ordered execution of tasks, variables, templates, handlers, and roles, supporting both synchronous and asynchronous operations.

Core Elements Tasks (list of operations), Variables, Templates, Handlers (triggered actions), Roles.

Deploying Nginx with a Playbook The example sets up two servers (192.168.20.41 as the Ansible control node and 192.168.20.42 as the target), distributes nginx_static.conf , and defines nginx_install.yaml with hosts, variables, tasks to install Nginx, copy the template, notify a handler to restart, and ensure the service is running.

- hosts: webservers
  vars:
    http_port: 8080
    server_name: www.hahashen.com
    remote_user: root
    gather_facts: false
  tasks:
    - name: 安装nginx
      yum: pkg=nginx state=latest
    - name: 写入nginx配置文件
      template: src=nginx_static.conf dest=/etc/nginx/nginx_static.conf
      notify:
        - restart nginx
    - name: 确保nginx正在运行
      service: name=nginx state=started enabled=yes
  handlers:
    - name: restart nginx
      service: name=nginx state=reloaded

Running ansible-playbook -C nginx_install.yaml checks the playbook syntax, and ansible-playbook nginx_install.yaml distributes the configuration and starts the service, as shown by the subsequent command‑line and screenshot outputs.

After deployment, verify the Nginx configuration with nginx -t , which should report "syntax is ok" and a successful test.
