我开始学习ansible,然后尝试安装PHP和php扩展。 我有一个文件,在其中声明了我的php版本和php扩展名,其外观如下:
php:
versions:
- 7.2:
- cli
- fpm
- curl
- mysql
- pdo
- zip
- xml
- gd
- mbstring
- tokenizer
- ctype
- json
- 7.3:
- cli
- fpm
- curl
- mysql
- pdo
- zip
- xml
- gd
- mbstring
- tokenizer
- ctype
- json
之所以这样做,是因为我想学习Ansible,并且还希望获得灵活性,并为每个php版本安装不同的扩展名。
我尝试以此调试我的代码(这在我的playbook.yml文件的“任务”部分下)
- name: DEBUG ANSIBLE PLAYBOOK
debug:
msg: The key is - {{ item.keys() | first }} The item is "{{ item[item.keys() | first] }}"
loop: "{{ php.versions }}"
loop_control:
loop_var: item
我得到以下输出:
TASK [DEBUG ANSIBLE PLAYBOOK]
ok: [127.0.0.1] => (item={7.2: [u'cli', u'fpm', u'curl', u'mysql', u'pdo', u'zip', u'xml', u'gd', u'mbstring', u'tokenizer', u'ctype', u'json']}) => {
"msg": "The key is - 7.2 The item is \"[u'cli', u'fpm', u'curl', u'mysql', u'pdo', u'zip', u'xml', u'gd', u'mbstring', u'tokenizer', u'ctype', u'json']\""
}
ok: [127.0.0.1] => (item={7.3: [u'cli', u'fpm', u'curl', u'mysql', u'pdo', u'zip', u'xml', u'gd', u'mbstring', u'tokenizer', u'ctype', u'json']}) => {
"msg": "The key is - 7.3 The item is \"[u'cli', u'fpm', u'curl', u'mysql', u'pdo', u'zip', u'xml', u'gd', u'mbstring', u'tokenizer', u'ctype', u'json']\""
}
然后我尝试使用此任务安装PHP:
- name: Install PHP
package:
pkg: php{{ item.keys() | first }}-{{ item[item.keys() | first] }}
state: latest
loop: "{{ php.versions }}"
loop_control:
loop_var: item
notify: Restart Nginx
但是不起作用,因为item[item.keys() | first]
是一个数组,我不知道如何再次循环以接收cli,fpt而不是数组。
我从3天开始学习ansible,但我真的不明白如何循环更多次。我在网上搜索,阅读了文档,但是我不理解
https://docs.ansible.com/ansible/2.4/playbooks_loops.html
如果有人可以解释,我将非常感谢!

一个选择是使用include_tasks。请参阅下面的提示。
tasks:
- include_tasks: test.yml
loop: "{{ php.versions }}"
loop_control:
loop_var: php_ver
。
> cat test.yml
- debug: msg="{{ lookup('dict', php_ver).key }}"
- debug: msg="{{ item }}"
loop: "{{ lookup('dict', php_ver).value }}"
这是剧本
> cat test-31.yml
---
- hosts: localhost
gather_facts: no
vars:
php:
versions:
- 7.2:
- cli
- fpm
- curl
- mysql
- pdo
- zip
- xml
- gd
- mbstring
- tokenizer
- ctype
- json
- 7.3:
- cli
- fpm
- curl
- mysql
- pdo
- zip
- xml
- gd
- mbstring
- tokenizer
- ctype
- json
tasks:
- include_tasks: test.yml
loop: "{{ php.versions }}"
loop_control:
loop_var: php_ver
这是输出

好吧,经过大量研究,我找到了解决方法
- name: Install PHP && Packages
become: true
package:
pkg: php{{ item.0.version }}-{{ item.1 }}
state: latest
with_subelements:
- "{{ php }}"
- libs
notify: Restart Nginx
为我工作。此外,我更改了数组:
php:
- version: 7.2
libs:
- cli
- fpm
- curl
- mysql
- pdo
- zip
- xml
- gd
- mbstring
- tokenizer
- ctype
- json
- version: 7.3
libs:
- cli
- fpm
- curl
- mysql
- pdo
- zip
- xml
- gd
- mbstring
- tokenizer
- ctype
- json
我在这里允许这样做,也许有人会觉得有用。
