centos MQTT安装和php使用mosquitto的实例
MQTT 是物联网的消息传送协议标准。
在 CentOS 7上常用的开源 MQTT 消息服务器就是 Mosquitto
有人用 PECL 来安装 Mosquitto 的 PHP 实现,反正我没有成功
pecl install Mosquitto-alpha
也可以用yum安装
yum install -y epel-release yum search mosquitto yum install -y mosquitto mosquitto-devel yum install -y php-devel yum install -y mosquitto-devel
如果安装不成功就用编译安装
包下载地址:https://github.com/mgdm/Mosquitto-PHP
phpize ./configure && make && make install
php.ini 添加 extension=mosquitto.so
重启php
mqtt.php
<?php
$client = new Mosquitto\Client();
$client->setCredentials('root','12345');
$client->connect("127.0.0.1", 1884, 5);
for($i = 0;$i<=100;$i++) {
$client->loop();
$mid = $client->publish('ss', "Hello from PHP at " . date('Y-m-d H:i:s'), 1, 0);
echo "Sent message ID: {$mid}\n";
$client->loop();
sleep(2);
}sub.php
<?php
$c = new Mosquitto\Client;
$c->setCredentials('root','12345');
$c->connect('127.0.0.1',1883,50);
$c->subscribe('ss', 1);
$c->onMessage(function($m) {
var_dump($m);
});
$c->loopForever();
