    Ansible Facts 变量详解 添加用户账号Ansible 配置清单Inventory

    Ansible Facts 变量详解与使用案例 主机规划 ? 因为这个收集托管主机上的 Facts 比较耗费时间,所以可以在不需要的时候关闭 setup 模块。收集的 Facts 中包含了托管主机特有的信息,这些信息可以像变量一样在 Playbook 中使用。 使用场景: 通过 facts 检查 CPU,生成对应的 Nginx 配置文件 通过 facts 检查内存情况,定义不同的 MySQL 配置文件或 Redis 配置文件 通过 facts 检查主机 hostname 4 --- 5 # facts 使用 6 - hosts: proxyservers 7 # 关闭 facts 变量 8 gather_facts: no 9 10 # 这时就不能取到 6 [yun@ansi-manager object03]$ cat test_facts.yml 7 --- 8 # facts 使用 9 - hosts: proxyservers 10

    -> facts.get("rain").equals(true)) .then(facts -> System.out.println("It rains, take an umbrella Facts facts = new Facts(); facts.put("rain", true); // define rules boolean evaluate(Facts facts); /** * This method encapsulates the rule's actions 举个栗子: Fact<String> fact = new Fact("foo", "bar"); Facts facts = new Facts(); facts.add(fact); 或者,也可以用这样简写形式 Facts facts = new Facts(); facts.put("foo", "bar"); 用@Fact注解可以将Facts注入到condition和action方法中 @Rule class

    变量 facts代表主机各种信息 收集facts信息 获取目标主机安装的详细信息 ansible_os_family 获取fqdn信息 ansible_fqdn 收集 关闭facts收集以后,playbook启动的时间会变快 - hosts: dev gather_facts: no tasks: - debug: msg: "closeed facts" 随时开启Facts收集 - hosts: dev gather_facts: no tasks: - setup: - debug: msg: - "closeed facts" - "{{ ansible_hostname }}" 自定义Facts变量 ansible 在收集主机信息的时候默认是在/etc/ansible/facts.d 1.自定义目录与内容,两种风格方式都可以 tail /home/ansible/facts.d/* ==> /home/ansible/facts.d/haha.fact <== [name] haha

    如何做好 Ansible 的配置优化?

    7.设置Facts缓存 当我们用ansible-playbook执行Playbook的时候,我们会发现,默认第一个Task都是GATHERING FACTS,这个过程就是Ansible收集每台主机的Facts 当然如果我们的Playbook中不需要Facts信息,可以在Playbook中设置gather_facts: False来提高Playbook的效率: ---- hosts: 10.0.108.2gather_facts 但是如果我们既想每次执行Playbook的时候都能收集Facts信息,又想加速这个收集过程,这时候可以设置Facts的缓存。 smart表示默认收集Facts,但Facts已有的情况下不会收集,即使用缓存Facts; implicit表示默认收集Facts,要禁止收集,必须使用gather_facts: False; explicit 表示默认不收集,要显式收集,必须使用gather_facts: Ture; 在使用Facts缓存时(即设置为smart),Ansible支持两种Facts缓存:redis和jsonfile。

    root@$host &> /dev/null done 将上面的方案playbook化: --- - name: config ssh connection hosts: new gather_facts 当指定的文件或者目录不存在时执行,存在不执行 removes:当指定的文件或者目录不存在时不执行,存在执行 --- - name: modules use hosts: new gather_facts ansible_password="yeecallk8s" 分发认证配置 --- - name: "configure ssh connection" hosts: new gather_facts etc/hosts')}} query() : 统配文件读取,返回list格式 --- - name: "fileglob and files query" hosts: new gather_facts task都能访问这些变量,其他的play则无法访问 设置在task级别,只有该task范围内才能访问这个变量 --- - name: vars task1 hosts: new gather_facts

    facts = new Facts(); facts.put("person", tom); MVELRule alcoholRule = MVELRuleFactory.createRuleFrom ; rules.register(alcoholRule); //create a default rules engine and fire rules on known facts ; rulesEngine.fire(rules, facts); 注解方式 @Rule public class BuzzRule { @Condition public , false otherwise */ boolean evaluate(Facts facts); /** * Rule actions abstraction facts) throws Exception; } 实现这个接口,也是创建rule的一种形式。
