1.zabbix 安裝流程
安裝過程 可以參考
https://www.zabbix.com/download?zabbix=5.0&os_distribution=centos&os_version=7&db=mysql&ws=nginx

2.zabbix agent Active Passive Mode

Passive Mode	Zabbix Server 輪詢連線到Zabbix Agent 10050端口上確認並取值
Active Mode	Zabbix Agent 每兩分鐘(預設值)連線到Zabbix Server 10051端口上並把數值送到Zabbix Server

Passive Mode 設定
確認Server 這個參數既可

#vi /etc/zabbix/zabbix_agentd.conf

Server=3.3.3.3 (你的Zabbix Server 或者是 Zabbix Proxy  被動模式)
ServerActive=3.3.3.3 (主動模式使用)
Hostname=主機名稱 (Agent上的Hostname必須與zabbix server上的 Hostname相同)

3.zabbix 獲取Nginx 連線狀態
在監控主機上生成ngx_status.sh腳本

#!/bin/bash
# Description：nginx status

HOST="127.0.0.1"
PORT="80"
# pid check
function ping {
    /sbin/pidof nginx | wc -l
}
# nginx status
function active {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| grep 'Active' | awk '{print $NF}'
}
function reading {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| grep 'Reading' | awk '{print $2}'
}
function writing {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| grep 'Writing' | awk '{print $4}'
}
function waiting {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| grep 'Waiting' | awk '{print $6}'
}
function accepts {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| awk NR==3 | awk '{print $1}'
}
function handled {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| awk NR==3 | awk '{print $2}'
}
function requests {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| awk NR==3 | awk '{print $3}'
}
# exe function
$1

#echo "UserParameter=nginx.status[*],/etc/zabbix/ngx_status.sh \$1" >> /etc/zabbix/zabbix_agentd.conf

完成後 restart zabbix-agent

#systemctl restart zabbix-agent.service

接著確認Nginx 是否有http_stub_status_module

#nginx -V 2>&1 | grep -o with-http_stub_status_module

確認有了話，設定nginx stub status (nginx.conf)

server {
    listen       80;
        server_name 127.0.0.1 localhost;
             location /ngx_status {
            stub_status on;
            access_log off;
            allow 127.0.0.1;
            deny all;
}

從nginx本地驗證是否正常運作

#curl http://127.0.0.1/ngx_status

Active connections: 1
server accepts handled requests
57495 57495 59094
Reading: 0 Writing: 1 Waiting: 0

從Zabbix Server 驗證是否正常運作

#zabbix_get -s 3.3.3.3 -k nginx.status[accepts]

4.通過API修改zabbix server HOST IP參數
獲取zabbix api token

#curl -X POST -s http://yourzabbix/zabbix/api_jsonrpc.php \

-H 'Content-Type:application/json' \

-d '{"jsonrpc": "2.0","method":"user.login","params":{"user":"'$user'","password":"'$pass'"},"auth": null,"id":0}' | jq -r .result

a8dad60295858044alksdjfdcb2499d51a6

獲取zabbix hostid

#curl -X POST -s http://yourzabbix/zabbix/api_jsonrpc.php \

-H 'Content-Type:application/json' \

-d '{"jsonrpc": "2.0","method":"host.get","params": {"output": ["host"],"search" :{"description": "hostname"}},"id": 1,"auth":"'$token'"}' | jq -r .result[] | jq -r .hostid

獲取zabbix interfaceid

#curl -X POST -s http://yourzabbix/zabbix/api_jsonrpc.php \

    -H 'Content-Type:application/json' \

    -d '{"jsonrpc": "2.0","method": "hostinterface.get","params": {"output": "extend","hostids": "'$hostid'"},"auth":"'$token'","id":1}' | jq -r .result[] | jq -r .interfaceid

5.忘記Zabbix 密碼
登入SSH Zabbix主機

#mysql -u root -p

mysql> use zabbix;

mysql> update zabbix.users set passwd=md5('zabbix') where alias='Admin';
