Ubuntu下搭建MQTT服务器

前言

现在物联网这么火，当然不能落伍，MQTT极有可能成为物联网应用最广的协议，因此需要一个MQTT测试环境就很有必要了

开发环境

系统： Ubuntu 16.04.3 LTS

代理服务器：Apache-Apollo-1.7.1

准备工作

1. 安装Java环境

由于搭建Apollo环境变量需要有JAVA_HOME，这个时候需要安装JDK,具体安装参考《Ubuntu安装JDK1.8.0并配置环境变量》

2. Apache-Apollo-1.7.1下载及解压

首先是下载Apache-Apollo，下载页面：http://www.apache.org/dyn/closer.cgi?path=activemq/activemq-apollo/1.7.1/apache-apollo-1.7.1-unix-distro.tar.gz

或者输入下面命令：

1

iotts@jacklu:~$ cd /home/iotts/
iotts@jacklu:~$ mkdir apache-apollo
wget http://mirror.bit.edu.cn/apache/activemq/activemq-apollo/1.7.1/apache-apollo-1.7.1-unix-distro.tar.gz

解压源码包：

1	tar -zxvf apache-apollo-1.7.1-unix-distro.tar.gz

配置

进入apache-apollo-1.7.1/bin目录

1	cd apache-apollo-1.7.1/bin/

输入./apollo可以查看帮助

iotts@jacklu:~/apache-apollo/apache-apollo-1.7.1/bin$ ./apollo
usage: apollo [--log <log_level>] <command> [<args>]

The most commonly used apollo commands are:
    create           creates a new broker instance
    disk-benchmark   Benchmarks your disk's speed
    help             Display help information
    version          Displays the broker version

See 'apollo help <command>' for more information on a specific command.

创建MQTT服务器

创建一个Broker示例：./apollo create iotts_broker。执行后就会在bin目录下创建 iotts_broker文件夹。(MQTT服务器都是叫Broker)

iotts@jacklu:~/apache-apollo/apache-apollo-1.7.1/bin$ ./apollo create iotts_broker
Creating apollo instance at: iotts_broker
Generating ssl keystore...

You can now start the broker by executing:  

   "/home/iotts/apache-apollo/apache-apollo-1.7.1/bin/iotts_broker/bin/apollo-broker" run

Or you can setup the broker as system service and run it in the background:

   sudo ln -s "/home/iotts/apache-apollo/apache-apollo-1.7.1/bin/iotts_broker/bin/apollo-broker-service" /etc/init.d/
   /etc/init.d/apollo-broker-service start

后面会有提示怎么启动服务器，以及创建一个service。

启动Apollo ：

iotts@jacklu:~/apache-apollo/apache-apollo-1.7.1/bin$ iotts_broker/bin/apollo-broker run

查看打印信息即可知道MQTT要连接的端口和管理页面端口。

然后打开浏览器上，输入 http://127.0.0.1:61680/ 或 https://127.0.0.1:61681/
即可进入 Apollo Console 窗口。

默认的登录id和密码是 admin 和 password
