在Ansible yaml文件中，限制每行代码的字符数为80个以内。可以采用换行符（\）或使用竖线（|）标记来实现。

例如：

• name: Install Nginx apt: name: nginx state: present
• name: Copy configuration file copy: src: files/config.conf dest: /etc/nginx/ owner: root group: root mode: '0644' backup: yes notify: Restart nginx

可以改写为：

• name: Install Nginx apt: name: nginx state: present

• name: Copy configuration file copy: src: files/config.conf dest: /etc/nginx/ owner: root group: root mode: '0644' backup: yes notify: Restart nginx

或者：

• name: Install Nginx apt: name: nginx state: present

• name: Copy configuration file copy: > src: files/config.conf dest: /etc/nginx/ owner: root group: root mode: '0644' backup: yes notify: Restart nginx

这样做能够有效解决Ansible lint中的Line too long问题。
