Question

我是新的安息世界。下面是我的ansible playbook，并在为tomcat端口应用模板值之前。我试图根据远程服务器上没有出现tomcat实例来计算端口。

如何在运行shell后使用local_action将值作为变量获取？

- 
  hosts: "{{Server}}"
  tasks:
    - 
      ignore_errors: true
      name: "find no of Tomcat Instance available on the Server"
      register: Tomcat_Instance_no
      shell: "find /example -name tomcat-users.xml -type f -print | wc -l"

    - debug: var=Tomcat_Instance_no
    #- local_action: copy content="{{ Tomcat_Instance_no.stdout }}" dest="/tmp/{{Server}}_Tomcat_Instance_no"
    #- local_action: "shell sh define-tomcat-instance-port.sh {{Server}} {{IName}} {{ Tomcat_Instance_no.stdout }}"
    ****- local_action: "shell sh http_port=$(( {{ Tomcat_Instance_no.stdout }} * 100 + 8080))"
      register: HTPN
    - local_action: "shell sh shutdown_port=$(( {{ Tomcat_Instance_no.stdout }} * 100 + 8005))"
      register: SHPN
    - local_action: "shell sh https_port=$(( {{ Tomcat_Instance_no.stdout }} * 100 + 8043))"
      register: SSPN
    - local_action: "shell sh ajp_port=$(( {{ Tomcat_Instance_no.stdout }} * 100 + 8009))"
      register: AJPN**

    #-
      #name: bare include
      #include_vars: "{{Server}}_{{IName}}.json"

    - 
      ignore_errors: true
      name: "find no of Tomcat Instance available on the Server"
      copy:
        src: "{{ WORKSPACE }}/instance/"
        dest: /example/{{IName}}
        group: "{{IGID}}"
        owner: "{{IUID}}"
        mode: 0755
    - 
      name: Deliver configuration files for tomcat
      template: src={{ item.src }} dest={{ item.dest }} backup=yes
      with_items:
          - { src: 'server.xml.j2', dest: '/example/{{IName}}/conf/server.xml' }
          - { src: 'set_env.sh.j2', dest: '/example/{{IName}}/scripts/set_env.sh' }

您需要set_fact：

{% load static %}    
{% block stylesheets %}
        <link rel="stylesheet" type="text/css" href="{% static "Emu86/style.css"%}">
{% endblock stylesheets %}

我还在- set_fact: HTPN: "{{ tomcat_no | int * 100 + 8080 }}" SHPN: "{{ tomcat_no | int * 100 + 8005 }}" SSPN: "{{ tomcat_no | int * 100 + 8043 }}" AJPN: "{{ tomcat_no | int * 100 + 8009 }}" vars: tomcat_no: "{{ Tomcat_Instance_no.stdout }}"任务中定义了tomcat_no别名来减少输入。

ansible playbook local_action计算值并赋值给变量
