🚀 ONEKEY 快速安装指南

本教程介绍 一键安装脚本 的使用方法，帮助您快速部署集群环境。
如果您希望深入了解安装原理，请参考 常规安装教程。

📌 适用环境

适用系统

• 操作系统：适用于 CentOS 7.9.2009
• 其他环境：未经测试，不保证兼容性

📌 安装步骤

1️⃣ 获取安装脚本

请先前往 微信公众号 获取 安装脚本下载链接 📎，然后将文件下载到您的服务器。

📌 公众号获取下载链接示例

2️⃣ 配置 hosts.txt

在解压后的目录中，找到 hosts.txt 文件，并按照以下格式填写 需要安装的集群节点信息：

**📌 格式说明**

<用户名> <密码> <IP地址>

✅ 示例

root Tt3832514048 192.168.3.1
root Tt3832514048 192.168.3.2
root Tt3832514048 192.168.3.3

📌 注意事项

• 每行填写一台服务器的信息
• 确保密码正确，IP 地址可访问
• 确保 hosts.txt 文件与安装脚本位于同一目录

3️⃣ 运行安装脚本

hosts.txt 配置完成后，执行以下命令启动安装过程：

bash install.sh

📌 文件示例

安装脚本会自动解析 hosts.txt，并在所有集群节点上执行安装任务。

4️⃣ 安装过程截图
