Ansible部署系列：（七）安装MinIO

7. 安装MinIO

7.1. 说明

可以做集群的文件服务器，安装使用的是Linux的二进制包，下载地址为https://dl.min.io/server/minio/release/linux-amd64/minio。

7.2. yml脚本

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

  tasks:
    - name: enforce env  #刷新环境变量
      shell: source ~/.bashrc
    - name: Create minio group
      group:
        name: minio
        state: present
    - name: Create minio user
      user:

        zone: public
        state: enabled
    - name: start minio
      service:
        name: minio.service
        state: started
        enabled: true
      tags:
        - start minio

7.3. 配置模板

7.3.1 env.j2

需要注意的是，MinIO的文件存储目录至少需要4个，如果有两个节点的话，可以每个节点创建两个目录，但这次安装只用了1个节点，因为在/home/data/minio路径下创建了4个目录。路径的指向可以在j2模板里MINIO_VOLUMES配置。如果有两个节点的话，每个节点两个目录即可。

# Local export path.
MINIO_VOLUMES="{%- for item in groups['minioservers'] -%}
    http://{{ hostvars[item].ansible_default_ipv4.address }}:9199{{ MINIO_DATA_DIR }}/data1 \
    http://{{ hostvars[item].ansible_default_ipv4.address }}:9199{{ MINIO_DATA_DIR }}/data2 \
    http://{{ hostvars[item].ansible_default_ipv4.address }}:9199{{ MINIO_DATA_DIR }}/data3 \
    http://{{ hostvars[item].ansible_default_ipv4.address }}:9199{{ MINIO_DATA_DIR }}/data4 {% if not loop.last %}\ {% endif %}
{% endfor -%}"
# Use if you want to run Minio on a custom port.
MINIO_OPTS="--address :9199"
 
# Access Key of the server.
MINIO_ACCESS_KEY={{ MINIO_USERNAME }}
# # Secret key of the server.
MINIO_SECRET_KEY={{ MINIO_SECRET_KEY }}

7.3.2 minio.service.j2

7.4. 运行ansible-playbook

ansible-playbook -i /etc/ansible/hosts minio/main.yml

7.5. 安装成功

MinIO的登录用户名和密码可以在vars.yml文件中找到，MINIO_USERNAME和MINIO_SECRET_KEY，登录地址是http://192.168.0.250:9199/minio/login

登录成功后需要给项目创建使用的bucket即可
