# 一、部署Zabbix 5.0環境

## 1.1、下載Zabbix 5.0映象

```sql
[root@docker36 ~]# docker pull registry.cn-hangzhou.aliyuncs.com/lhrbest/lhrzabbix5:1.0
1.0: Pulling from lhrbest/lhrzabbix5
c1e1cb5fc6d2: Already exists 
f36cbc8bf71f: Pull complete 
Digest: sha256:5e22edb3347a27a731bd48742c982e34dcbcd47b63db2e9b64549ad69488475e
Status: Downloaded newer image for registry.cn-hangzhou.aliyuncs.com/lhrbest/lhrzabbix5:1.0
registry.cn-hangzhou.aliyuncs.com/lhrbest/lhrzabbix5:1.0
```

## 1.2、建立映象

```sql
[root@docker36 ~]# docker run -d --name lhrzabbix5 -h lhrzabbix5 \
>   -p 225:22 -p 23306:3306 -p 280:80 -p 20051:10051 \
>   -v /sys/fs/cgroup:/sys/fs/cgroup \
>   --privileged=true \
>   lhrbest/lhrzabbix5:1.0 /usr/sbin/init

[root@docker36 ~]# docker exec -it lhrzabbix5 bash
[root@lhrzabbix5 /]# 
```

## 1.3、瀏覽器訪問

訪問Zabbix：http://192.168.66.36:280/zabbix

預設使用者名稱密碼：Admin/zabbix

# 二、監控Linux主機

監控Linux主機可以透過snmp（Simple Network Management Protocol）簡單網路管理協議，也可以透過zabbix-agent監控。本文使用snmp來配置。

```sql
yum install -y net-snmp net-snmp-utils

systemctl start snmpd
systemctl status snmpd
systemctl enable snmpd
```

配置檔案：vi  /etc/snmp/snmpd.conf，新增如下內容：

```
view systemview included .1 
```

啟動snmpd：

```sql
[root@lhrzabbix5 ~]# systemctl status snmpd
● snmpd.service - Simple Network Management Protocol (SNMP) Daemon.
   Loaded: loaded (/usr/lib/systemd/system/snmpd.service; enabled; vendor preset: disabled)
   Active: active (running) since Wed 2021-01-13 16:37:24 CST; 39s ago
 Main PID: 81937 (snmpd)
   CGroup: /system.slice/snmpd.service
           └─81937 /usr/sbin/snmpd -LS0-6d -f

Jan 13 16:37:24 docker36 systemd[1]: Starting Simple Network Management Protocol (SNMP) Daemon....
Jan 13 16:37:24 docker36 snmpd[81937]: NET-SNMP version 5.7.2
Jan 13 16:37:24 docker36 systemd[1]: Started Simple Network Management Protocol (SNMP) Daemon..
[root@docker36 ~]# netstat -anp | grep 161
udp        0      0 0.0.0.0:161             0.0.0.0:*                           81937/snmpd 
```

在zabbix server上測試：

```
nc -zvu localhost 161
snmpwalk -v 2c -c public localhost | wc -l
```

結果：

```sql
[root@lhrzabbix5 /]# nc -zvu  localhost 161
Ncat: Version 7.50 ( https://nmap.org/ncat )
Ncat: Connected to 127.0.0.1:161.
Ncat: UDP packet sent successfully
Ncat: 1 bytes sent, 0 bytes received in 2.02 seconds.
[root@lhrzabbix5 /]# snmpwalk -v 2c -c public localhost | wc -l
7086
```

此時需要在server端配置：

配置——主機——建立主機——移除interface的客戶端——新增SNMP客戶端

——填寫主機名稱、可見名稱、群組、IP地址，如圖所示：

![](https://gitee.com/lhrbest/pic/raw/master/img/20210201173758.png)

點選新增，然後等待1分鐘，等待圖示變成綠色即正常，如圖所示：

監控結果：

# 三、監控MySQL例項

被監控端Mysql主機安裝Zabbix-agent

```sql
rpm -ivh http://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm

sed -i "s/gpgcheck=1/gpgcheck=0/g" /etc/yum.repos.d/zabbix.repo
yum -y install zabbix-agent
```

被監控端修改zabbix-agent配置檔案

```sql
vim /etc/zabbix/zabbix_agentd.conf

Server=localhost
Hostname=mysql-local

systemctl restart zabbix-agent
systemctl enable zabbix-agent

ss -antulp | grep :10050

日誌： /var/log/zabbix/zabbix_agentd.log
```

被監控端修改MySQL配置檔案：

```sql
mkdir -p /var/lib/zabbix
cat > /var/lib/zabbix/.my.cnf < ● 本文作者：小麥苗，部分內容整理自網路，若有侵權請聯絡小麥苗刪除
