【MQTT】Mosquitto的安装与使用流水记
最近使用MQTT，安装Mosquitto试一下，并记录下来。
软件准备
从官网获取安装包：
wget http://mosquitto.org/files/source/mosquitto-1.4.14.tar.gz
还需要安装一些依赖的软件，我的机器目前缺少的软件（你的机器可能缺少的更多）：
yum install libuuid-devel
安装
tar -zxvf mosquitto-1.4.14.tar.gz
cd /third_pkg/mosquitto-1.4.14
修改配置文件/third_pkg/mosquitto-1.4.14/config.mk的WITH_SRV:=yes为no。
make
make install
启动
查下命令在哪里：
[root@localhost mosquitto-1.4.14]# whereis mosquitto
mosquitto: /etc/mosquitto /usr/local/sbin/mosquitto
启动：
[root@localhost mosquitto-1.4.14]# /usr/local/sbin/mosquitto -c /etc/mosquitto/mosquitto.conf
1501414546: mosquitto version 1.4.14 (build date 2017-07-30 19:32:01+0800) starting
1501414546: Using default config.
1501414546: Opening ipv4 listen socket on port 1883.
1501414546: Opening ipv6 listen socket on port 1883.
1501414546: Error: Invalid user 'mosquitto'.
发现无此用户，启动失败，就添加此用户adduser mosquitto，然后再次启动。
测试
消费者
启动一个消费者：
/usr/local/bin/mosquitto_sub -h 127.0.0.1 -t myqueue
生产者
使用生产者发送一个消息：
mosquitto_pub -h 127.0.0.1 -t myqueue -m "hello world"
