三、二进制安装 - 自定义部署

下载 VictoriaMetrics 二进制可执行文件 or Docker image ，然后以命令行参数启动。

victoriametrics_repo_url: "https://github.com/VictoriaMetrics/VictoriaMetrics"
victoriametrics_download_url:  "{{ victoriametrics_repo_url }}/releases/download/{{ victoriametrics_version }}/victoria-metrics-{{ victoriametrics_version }}.tar.gz"
victoriametrics_version: "v1.28.0"
victoriametrics_system_user: "victoriametrics"
victoriametrics_system_group: "{{ victoriametrics_system_user }}"
victoriametrics_delete_auth_key: "secret"
victoriametrics_snapshot_auth_key: "secret"
victoriametrics_service_args: ""

创建部署脚本 deploy_victoriametric.sh，如下

#!/bin/bash
# 设置环境变量
