<h2 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">1、</span>安装预置<span style="color: black;">要求</span></h2>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">EMQ X <span style="color: black;">能够</span>跨平台运行在 Linux、FreeBSD、MacOS 或 Windows 服务器<span style="color: black;">乃至</span>是树莓派上。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">服务器最低配置为 512MB 内存且<span style="color: black;">最少</span><span style="color: black;">保存</span> 1 GB 以上硬盘空间。</p>
<h2 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">2、</span>二进制包安装</h2>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">EMQ 官网 <span style="color: black;">供给</span>热门 Linux 发行版、MacOS、Windows 操作系统以及 Docker 镜像的二进制包下载，当前支持的操作系统及平台请到官网下载页查阅。</p>
<h2 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">3、</span>源码编译安装</h2>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">部分官网未<span style="color: black;">供给</span>二进制包的操作系统与平台如 Linux ARM、FreeBSB，可<span style="color: black;">运用</span>源码编译安装。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">EMQ X 基于 Erlang/OTP 平台<span style="color: black;">研发</span>，项目托管的 GitHub 管理<span style="color: black;">守护</span>，源码编译依赖 Erlang 环境和 git 客户端。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">EMQ X 3.0+ 依赖 Erlang R21+ 版本。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">EMQ X Enterprise 暂未<span style="color: black;">供给</span>源码编译安装，如有特殊运行环境<span style="color: black;">需要</span>请联系 contact@emqx.io</p>
<h2 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">4、</span>首次安装 EMQ X</h2>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在安装 EMQ X 前，请确认安装的 前置<span style="color: black;">要求</span> 都<span style="color: black;">已然</span>满足。</p>
<h2 style="color: black; text-align: left; margin-bottom: 10px;">版本<span style="color: black;">选取</span></h2>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">EMQ X 支持多种操作系统，请<span style="color: black;">选取</span>合适您的版本下载。</p>
<h2 style="color: black; text-align: left; margin-bottom: 10px;">1、在 Linux 下安装</h2>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">针对</span> Linux 发布，EMQ X <span style="color: black;">供给</span>两种方式的安装。一是基于各 linux 发布的安装包。用安装包安装 EMQ X 以后，<span style="color: black;">能够</span>方便的<span style="color: black;">运用</span>系统管理工具来启停 EMQ X 服务。二是<span style="color: black;">运用</span> zip 压缩打包的通用包。安装 zip 包只需解压 zip 文件<span style="color: black;">就可</span>。<span style="color: black;">运用</span> zip 包<span style="color: black;">能够</span>实<span style="color: black;">此刻</span>同一个系统下安装多套 EMQ X。在<span style="color: black;">研发</span> / 实验室环境下<span style="color: black;">运用</span> zip 包安装 EMQ X 非常实用。</p>
