安装 Ansible 软件

[root@jenkins_master ~]# yum -y install ansible-2.9.27-1.el7

验证 Ansible 安装结果

[root@jenkins_master ~]# ansible --version
ansible 2.9.27
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Aug  7 2019, 00:51:29) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]

创建构建目录

[root@jenkins_master ~]# mkdir /usr/local/jenkins/build

赋权 Jenkins 构建目录

[root@jenkins_master ~]# chown -R jenkins.jenkins /usr/local/jenkins/build

• 配置 Ansible Inventory 文件

[root@jenkins_master ~]# tail -6 /etc/ansible/hosts 
[master]
10.10.200.235

[build]
10.10.200.236
10.10.200.238

编写 Ansible Playbook

[root@jenkins_master ~]# cat /usr/local/jenkins/playbook/jenkins_ansible_test.yml 
---

- name: Run the test playbook
  gather_facts: false
  hosts: localhost
  tasks:
    - name: Get the username running this playbook
      become: false
      local_action: command whoami
      register: username_on_the_host

    - name: Display the User name
      ansible.builtin.debug:
        msg: "Hello User {{ username_on_the_host.stdout }} from Jenkins and Ansible!!"
