Zabbix MQQT协议监控 loT设备

一. 项目背景

监控异地局域网主机（主机内有物联5G卡 可以单方面向特定的云服务器传输信息）这里采用 zabbix 5xx系列 agent2 -6.2 版本 主动模式，即客户端向服务端注册。

 

二. 部署服务端

2.1 安装docker

#01 安装docker
# step 1: 安装必要的一些系统工具
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
# Step 2: 添加软件源信息
sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# Step 3
sudo sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
# Step 4: 更新并安装Docker-CE
sudo yum makecache fast
sudo yum -y install docker-ce
# Step 4: 开启Docker服务
sudo service docker start

#02 设置镜像加速
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://9akof579.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

 

1. 安装docker-compose

  #01 下载docker-compose
  curl -L https://get.daocloud.io/docker/compose/releases/download/1.29.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

  #02 给docker-compose目录授权  s
  udo chmod +x /usr/local/bin/docker-compose

  #03 查看一下version 显示有版本号那就说明安装成功了
  docker-compose version

1. 部署服务

#01 创建数据目录
mkdir -p /opt/zabbix
cd /opt/zabbix/

#02 docker-compose 文件
[root@centos7 zabbix]# cat docker-compose.yml
version: '3'

#03 创建目录
mkdir alertscripts db fonts

#04 安装中文语言包
cd fonts
wget https://dl.cactifans.com/zabbix_docker/msty.ttf
mv msty.ttf DejaVuSans.ttf

#05 启动服务
docker-compose up -d

3.启动检查

1. 浏览器访问 主机IP+8080端口 默认账户密码：Admin zabbix
2. 系统语言汉化（图一）
3. 我们要修改一下配置，将ip更换为容器名称，不然会检测不到（图二，删除IP 换成 dns名称加端口）

   

   

 

 

4.自动发现

 

三. 客户端配置

3.1 安装agent2

## 监控客户端服务器
1） 安装服务 并修改配置文件
yum install -y zabbix-agent2
# 由于网络原因 这里选择wget安装
wget https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-agent2-5.0.13-1.el7.x86_64.rpm
yum localinstall -y zabbix-agent2-5.0.13-1.el7.x86_64.rpm 

2) 修改systemctl管理的单元文件
# 修改agent2配置文件，修改如下，填写zabbix-server主机ip和主机名
[root@centos7 zabbix]# egrep -v  '^#|^$' /etc/zabbix/zabbix_agent2.conf
PidFile=/var/run/zabbix/zabbix_agent2.pid
LogFile=/var/log/zabbix/zabbix_agent2.log
LogFileSize=0
Server=192.168.5.249        # 服务端ip
ServerActive=192.168.5.249  # 服务端ip
Hostname=
HostnameItem=system.hostname    # 客户端主机名
HostMetadataItem=system.uname   # 客户端系统信息
Include=/etc/zabbix/zabbix_agent2.d/*.conf
ControlSocket=/tmp/agent.soc

3）重启服务
[root@db01 ~]$ systemctl restart zabbix-agent2.service 

4）服务端去验证
zabbix_get -s 10.0.0.7 -p 10050 -k 'agent.ping'

3.2 页面验证

 

 

监控 nginx 11种状态

 

#  tcp的11种状态每种状态的数量 

1) 需要的命令
root@web01 ~]# netstat -tna
[root@web01 ~]# netstat -tna | awk '{print $NF}' | sort  | uniq -c | sort -rn | awk 'BEGIN{print "TCP状态 \t","连接数量"} {print $2"\t",$1} ' |column -t
TCP状态       连接数量
LISTEN        11
TIME_WAIT     10
SYN_SENT      1
State         1
ESTABLISHED   1
established)  1

 

四. MQQT 协议收集消息

##注意
MQQT服务器为中转服务器，即客户端和服务端都订阅该服务器
1）zabbix服务端
2）zabbix客户端
3）mqqt服务器

#01 安装MQTT服务器（mosquitto）
1) 安装编译环境
yum install gcc-c++ cmake openssl-devel -y

2）下载mosquitto
wget http://mosquitto.org/files/source/mosquitto-1.6.8.tar.gz

3）解压 编译 安装
echo "解压"
tar -zxvf mosquitto-1.6.8.tar.gz
echo "进入mosquitto-1.6.8"cd mosquitto-1.6.8
echo "编译"
make
echo "安装"
sudo make install

4）修改链接路径，重新加载动态链接库
sudo ln -s /usr/local/lib/libmosquitto.so.1 /usr/lib/libmosquitto.so.1
sudo ldconfig

5）创建配置文件 和用户 用户组
cp /etc/mosquitto/mosquitto.conf.example /etc/mosquitto/mosquitto.conf
sudo groupadd mosquitto
sudo useradd -g mosquitto mosquitto -s /sbin/nologin

6) 启动、查看、关闭程序
echo "运行程序"
mosquitto -c /etc/mosquitto/mosquitto.conf -d
echo "ps查看"
ps -aux | grep mosquitto
echo "关闭程序"kill -9 $(pidof mosquitto)

7）本地简单测试
# 打开一个订阅者
mosquitto_sub -t topic

# 打开一个发布者
mosquitto_pub -t topic -m "发布内容"

https://zhuanlan.zhihu.com/p/164930347

• Python 实现订阅和发布

##订阅
# -*- coding: utf-8 -*-
import paho.mqtt.client as mqtt

def on_connect(client, userdata, flags, rc):
    print("Connected with result code: " + str(rc))

def on_message(client, userdata, msg):
    print(msg.topic + " " + str(msg.payload))

client = mqtt.Client()
#设置用户名和密码
# client.username_pw_set("mosquitto", "mosquitto")
client.on_connect = on_connect
client.on_message = on_message
#client.on_disconnect = on_disconnect
#连接 IP port keepalive
client.connect('101.200.170.7', 1833, 600)
#订阅的 topic
client.subscribe('test', qos=0)
client.loop_forever()

###发布
# -*- coding: utf-8 -*-
import paho.mqtt.client as mqtt

def on_connect(client, userdata, flags, rc):
    print("Connected with result code: " + str(rc))

def on_message(client, userdata, msg):
    print(msg.topic + " " + str(msg.payload))

client = mqtt.Client()
#设置用户名和密码
#client.username_pw_set("mosquitto", "mosquitto")
client.on_connect = on_connect
client.on_message = on_message
#连接 IP port keepalive
client.connect('101.200.170.7', 1833, 600)
#发布 topic 内容
client.publish('test', payload='111ing', qos=0)

 

• 添加监控项

#01 监控项参数

mqtt.get["tcp://192.168.5.249:1833","test"]

mqqt服务器地址和端口："tcp://192.168.5.249:1833"
topic 名称：test (自定义 需要先创建订阅)

例如：mosquitto_sub -t topic
