项目实战-物联网平台搭建-mqtt服务器搭建（一）

向右看齐 2022-12-13 04:35 342阅读 0赞

本项目为大四物联网中间件的课程设计

由于前期未拿到硬件平台以及传感器，所以先做软件方面

**首先先搭建mqtt服务器**，先看一下目前各类mqtt服务器的对比，下图：

**我选择了emq x。**

anyone：你为什么选择emq x而不选择别的？难道是因为是基于Erlang/OTP 语言平台开发的？

me：Erlang/OTP 语言？ 听都没听过，也就只是它运气好而已啊，一见钟情（其实以前用过一款mqtt服务器只是忘了叫什么了。。。）。

anyone：哪emq x有什么优势？

me：。。。。目前没发现什么优势，好像大多mqtt服务器都长得一样。

不扯了，**开始安装**

我是用的阿里云的服务器系统镜像**centos7.3**

# **emq x安装** #

如果之前有安装emq x

先卸载:

sudo yum remove emqx emqx-edge emqx-ee

安装依赖包：

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

使用以下命令设置存储库，以 CentOS7 为例

$ sudo yum-config-manager --add-repo https://repos.emqx.io/emqx-ee/redhat/centos/7/emqx-ee.repo

安装最新版本的 EMQ X

$ sudo yum install emqx-ee

![2020101011171667.png][]

启动：

emqx start

如果现实15s内启动失败

则需要升级一下openssl：

yum update openssl

再次启动就可以了

![20201010111940115.png][]

现在登录mqtt服务器管理页面地址为[http://你的ip:18083][http_ip_18083]

初次登录用户名是：admin 密码是：public

建议修改登录密码，不然很容易被扫到登陆的。
