**1 Mosquitto**  
**1.1 安装验证**

# 开放1883端口访问
    firewall-cmd --zone=public --add-port=1883/tcp --permanent
    firewall-cmd --reload

tar zxvf mosquitto-1.6.9.tar.gz
    cd mosquitto-1.6.9
    make && make install
    adduser mosquitto
    cp pwfile.example pwfile
    cp /etc/mosquitto/mosquitto.conf.example /etc/mosquitto/mosquitto.conf
    # mosquitto.conf添加内容如下
    allow_anonymous true
    password_file /etc/mosquitto/pwfile
    port 1883
    #确定命令
    mosquitto -c /etc/mosquitto/mosquitto.conf

测试验证

[root@localhost mosquitto]# mosquitto_sub -t rulee
    mosquitto_sub: error while loading shared libraries: libmosquitto.so.1: cannot open shared object file: No such file or directory

则参考[MQTT研究之mosquitto：【环境搭建】][MQTT_mosquitto]执行

echo "/usr/local/lib" >> /etc/ld.so.con
    ldconfig

在打开一个客户端执行`mosquitto_pub -h localhost -t rulee -m "hello world"`,看到消息了，说明成功了

[root@localhost mosquitto]# mosquitto_sub -t rulee
    hello rule engine

现在加上访问控制,参考[Mosquitto 搭建及配置][Mosquitto]

# 设置密码
    mosquitto_passwd /etc/mosquitto/pwfile mosquitto
    ############# mosquitto.conf
    allow_anonymous false
    password_file /etc/mosquitto/pwfile
    acl_file /etc/mosquitto/aclfile
    port 1883
    pid_file /var/run/mosquitto.pid
    # 持久化
    persistence true
    persistence_location /application/mosquitto/
    # 日志
    log_dest file /application/log/mosquitto/mosquitto.log
    
    ############# mosquitto.conf
    user mosquitto
    topic write test/#
    topic read test/#
    
    ############# 验证是否可以订阅、发布
    mosquitto_sub -h 10.101.5.131 -t "test/#" -u mosquitto -P test123 -i "client1"
    mosquitto_pub -h 10.101.5.131 -t "test/abc" -u mosquitto -P test123 -i "client3" -m "hello world"

上述那些都是在本地测试的，现在来通过mqtt工具，比如通信猫来调试  
无法连接上MQTT服务器，通过telent监测一下，如果telnet没有开启，参考[telnet不是内部或外部命令,小编教你telnet不是内部或外部命令怎么解决][telnet_telnet]  
![1][]  
性能指标可参考[MQTT SERVER 性能测试报告][MQTT SERVER]，这个没必要非要自己做一次验证。  
Mosquitto 属于轻量级，故而用户管理就不擅长，难道每添加一个用户都要改配置重启？  
**1.2 内网穿透**  
先参考[使用公共MQTT服务器进行HTTP内网穿透][MQTT_HTTP]
