在 AWS 中通过 Ansible 部署时如何设置 Apache 2.4 环境？

使用下面的剧本，我发现 /etc/apache2/envvars 设置不正确。我发现 Apache 2.4 将通过 apache2ctl 模块启动，并尝试使用它来启动服务。启动 EC2 实例后，我发现 Apache2.4 服务由于错误而未运行。一切都由这个剧本完成：

--- # Build Web Server
- name: Install Apache
hosts: localhost
become: yes
connection: local
gather_facts: yes
tasks:

- name: Add Repository for PHP 5.6
  apt_repository:
    repo: ppa:ondrej/php
    state: present

- name: Install Web Server Package
  apt:
    pkg: "{{ item }}"
    state: present
    update_cache: yes
  with_items:
  - "apache2"
  - "php5.6"
  - "php5.6-mbstring"
  - "php5.6-mcrypt"
  - "php5.6-mysql"
  - "php5.6-xml"
  - "php5.6-cli"
  - "libapache2-mod-php5.6"

- name: enable modules
  command: "a2enmod {{item}}"
  with_items:
  - rewrite
  - ssl


- name: Update Apache Config
  copy:
    src: /data/000-default.conf
    dest: /etc/apache2/sites-available
    owner: root
    group: root
    mode: 0644

- name: Enable Default website
  command: "a2ensite 000-default.conf"

- name: Update PHP CLI php.ini
  lineinfile:
    dest: /etc/php/5.6/cli/php.ini
    state: present
    insertbefore: EOF
    regexp: '^error_reporting'
    line: 'error_reporting = E_ALL & ~E_NOTICE & ~E_WARNING & ~E_STRICT & ~E_DEPRECATED'

  notify:
    - StartHttpd
  tags:
  - installapache
  handlers:
  - name: StartHttpd
    command: "apache2ctl restart"

运行上述剧本后......

答案1

使用service: name=apache（name可能因发行版而异）。apache2ctl抱怨环境变量未设置。这些参数可能是在启动期间使用 init 管理器（通过模块调用service）设置的。
