ansible Playbook案例 安装nginx

### 使用 Ansible Playbook 安装 Nginx 的案例 以下是基于多个引用内容整理的一个完整的 Ansible Playbook 示例，用于安装和配置 Nginx： #### 1. 准备工作 确保已经正确配置了 Ansible 环境，并且目标主机已添加到 `hosts` 文件中。 ```yaml --- - name: Install and Configure Nginx hosts: web become: true tasks: - name: Ensure required packages are installed yum: name: "{{ item }}" state: present loop: - gcc - make - openssl-devel - pcre-devel - zlib-devel - wget tags: preparation - name: Download Nginx source package shell: | cd /tmp/ wget https://nginx.org/download/nginx-1.21.6.tar.gz register: download_result failed_when: "'404 Not Found' in download_result.stdout" changed_when: "'saved' in download_result.stderr or 'already exists' not in download_result.stderr" tags: download - name: Extract the downloaded archive unarchive: src: /tmp/nginx-1.21.6.tar.gz dest: /tmp/ remote_src: yes tags: extraction - name: Compile and install Nginx from source shell: | cd /tmp/nginx-1.21.6 ./configure --prefix=/usr/share/nginx \ --conf-path=/etc/nginx/nginx.conf \ --error-log-path=/var/log/nginx/error.log \ --http-log-path=/var/log/nginx/access.log \ --pid-path=/run/nginx.pid \ --with-http_ssl_module make && make install args: creates: /usr/share/nginx/sbin/nginx tags: compilation - name: Create necessary directories for logs file: path: "/var/log/nginx/{{ item }}" state: directory mode: '0755' with_items: - access.log - error.log notify: restart nginx tags: log_directories - name: Copy custom configuration files to target host copy: src: /path/to/local/nginx.conf dest: /etc/nginx/nginx.conf owner: root group: root mode: '0644' notify: reload nginx tags: config_copy - name: Start and enable Nginx service systemd: name: nginx state: started enabled: yes tags: service_management handlers: - name: Restart Nginx systemd: name: nginx state: restarted - name: Reload Nginx Configuration systemd: name: nginx state: reloaded ``` 此脚本涵盖了从依赖包安装、源码下载编译到最终服务启动的全过程[^3]。如果只需要通过 Yum 或 Apt 包管理器快速安装，则可以简化为以下版本[^4]: ```yaml --- - name: Quick Installation of Nginx via Package Manager hosts: web become: true tasks: - name: Install Nginx using YUM (for CentOS/RHEL) yum: name: nginx state: present - name: Start and Enable Nginx Service service: name: nginx state: started enabled: yes ``` 以上两种方法均可实现 Nginx 的安装与运行，具体选择取决于实际需求以及环境条件。 --- ###
