Ansible部署系列：（十）安装RabbitMQ

10. 安装RabbitMQ

10.1. 说明

想通过yum仓库直接安装rabbitmq-server，但还是失败，只能还是使用下载的包进行离线安装。erlang是安装成功，但需要--nogpgcheck，在ansible里可以配置。

10.2. yml脚本

---
- hosts: rabbitmqservers
  remote_user: root
  vars_files:
    - ../vars.yml

  tasks:
  - name: Copy rabbitmq_erlang.repo
    template:
      src: "{{ PLAYBOOK_DIR }}/rabbitmq/templates/rabbitmq_erlang.repo.j2"
      dest: /etc/yum.repos.d/rabbitmq_erlang.repo
      owner: root
      group: root
      mode: "u=rw,g=r,o=r"

  - name: install erlang
    yum:
      name: erlang

      group: root
      mode: 0755

  - name: install rabbitmq-server
    yum:
      name: "/home/rabbitmq-server-3.8.14-1.el7.noarch.rpm"
      state: present

  - name: firewarld add 15672
    firewalld:

      permanent: true
      immediate: true
      zone: public

  - name: firewarld add 5672
    firewalld:

      permanent: true
      immediate: true
      zone: public
      state: enabled

  - name: chkconfig
    shell: chkconfig rabbitmq-server on
    run_once: true

  - name: start rabbitMQ
    service:
      name: rabbitmq-server
      state: started
    tags:

# PackageCloud's repository key and RabbitMQ package signing key
gpgkey=https://packagecloud.io/rabbitmq/erlang/gpgkey
       https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc

浏览器远程访问http://192.168.0.129:15672, 出现登录界面

10.6. 设置管理员

默认用户名guest，密码guest只能访问localhost，因此需要开启远程访问

rabbitmqctl add_user admin 123456
rabbitmqctl set_user_tags admin administrator
rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"

登陆成功后就看到以下页面
