Zabbix系列之四：Nginx并发监控

约定不等于承诺〃 2023-06-25 10:06 22阅读 0赞

### 安装nginx ###

首先需要下载nginx安装tar包，地址为：[http://nginx.org/download/][http_nginx.org_download]，并将其上传至机器，对其进行解压

> tar -zxvf nginx-1.2.6.tar.gz

> yum -y install pcre pcre-devel zlib zlib-devel

创建nginx用户：\#useradd -s /sbin/nologin -M nginx

开始安装：

> \#./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http\_stub\_status\_module
> 
> \#make && make install

测试是否安装成功：

> echo "hadoop" >>/usr/local/nginx/html/index.html
> 
> /usr/local/nginx/sbin/nginx
> 
> curl localhost

修改vi /usr/local/nginx/conf/nginx.conf配置文件

检测语法是否正常：/usr/local/nginx/sbin/nginx -t  
重载：kill -HUP $(cat /usr/local/nginx/logs/nginx.pid)

从上图可以看到连接数

### 编写shell脚本： ###

#!/bin/bash
    
    HOST="127.0.0.1"
    PORT="80"
    
    #nginx if not exeit
    function ping {
      /sbin/pidof nginx |wc -l
    }
    
    #nginx  performance
    function active {
      /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null|grep 'Active' |awk '{print $NF}'
    }
    function reading {
      /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null|grep 'Reading' |awk '{print $2}'
    }
    function writing {
      /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null|grep 'Writing' |awk '{print $4}'
    }
    function waiting {
      /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null|grep 'Waiting' |awk '{print $6}'
    }
    function accepts {
      /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null|awk NR==3 |awk '{print $1}'
    }
    function handled {
      /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null|awk NR==3 |awk '{print $2}'
    }
    function requests {
      /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null|awk NR==3 |awk '{print $3}'
    }
    
    $1

赋予执行权限：chmod a+x nginx-status.sh

### 在客户端添加自定义脚本规则 ###

mv nginx-status.sh /etc/zabbix/zabbix\_agentd.d

vi /etc/zabbix/zabbix\_agentd.conf

> UnsafeUserParameters=1    \#表示开启自定义脚本
> 
> UserParameter=nginx.status\[\*\],/etc/zabbix/zabbix\_agentd.d/nginx-status.sh $

systemctl restart zabbix-agent

再其他某一机器（192.168.1.173）执行命令：while 2>1;do curl 192.168.1.172;done

### 在服务端使用zabbix-get测试脚本获取数据情况 ###

在192.168.1.171机器上安装zabbix-get:yum -y install zabbix\_get

> zabbix\_get -s 192.168.1.172 -k 'nginx.status\[requests\]'   \#192.168.1.171机器执行

开始配置zabbix页面：

查看是否导入成功

将之前的172主机删除，重新创建主机，添加nginx模板，

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 6][]

至此，nginx并发监控已完成。
