可以使用以下的Ansible Playbook示例代码来部署ES集群,其中涉及到了ES的版本和安全认证配置:
```yaml
- name: Deploy Elasticsearch 7.17 cluster
hosts: es_cluster
become: true
vars:
es_version: 7.17
es_cluster_name: my_cluster
es_node_name: "{{ inventory_hostname }}"
es_heap_size: 1g
es_security_enabled: true
es_users:
- username: "admin"
password: "my_password"
roles: ["superuser"]
tasks:
- name: Download Elasticsearch package
get_url:
url: "https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-{{ es_version }}-linux-x86_64.tar.gz"
dest: "/tmp/elasticsearch-{{ es_version }}.tar.gz"
validate_certs: false
timeout: 600
- name: Extract Elasticsearch package
unarchive:
src: "/tmp/elasticsearch-{{ es_version }}.tar.gz"
dest: "/opt/elasticsearch-{{ es_version }}"
remote_src: true
creates: "/opt/elasticsearch-{{ es_version }}/bin/elasticsearch"
- name: Configure Elasticsearch
template:
src: "elasticsearch.yml.j2"
dest: "/opt/elasticsearch-{{ es_version }}/config/elasticsearch.yml"
owner: "elasticsearch"
group: "elasticsearch"
mode: "0644"
- name: Configure Elasticsearch security
template:
src: "users_roles.yml.j2"
dest: "/opt/elasticsearch-{{ es_version }}/config/users_roles.yml"
owner: "elasticsearch"
group: "elasticsearch"
mode: "0644"
- name: Start Elasticsearch service
systemd:
name: "{{ es_cluster_name }}"
state: started
enabled: true
daemon_reload: true
```
在上述代码中,使用了ES版本变量 `es_version` 和集群变量 `es_cluster_name`,并且设置了节点名称 `es_node_name` 和堆大小 `es_heap_size`。同时,也开启了安全认证并配置了管理员用户 `admin`,并使用了模板文件 `elasticsearch.yml.j2` 和 `users_roles.yml.j2` 来生成配置文件。
需要注意的是,该代码示例仅供参考,具体的ES集群部署方式需要根据实际情况进行调整。
