zabbix监控nginx状态

状态页面信息详解：

状态码	表示的意义
Active connections 2	当前所有处于打开状态的连接数
accepts	总共处理了多少个连接
handled	成功创建多少握手
requests	总共处理了多少个请求
Reading	nginx读取到客户端的Header信息数，表示正处于接收请求状态的连接数
Writing	nginx返回给客户端的Header信息数，表示请求已经接收完成，且正处于处理请求或发送响应的过程中的连接数
Waiting	开启keep-alive的情况下，这个值等于active - (reading + writing)，意思就是Nginx已处理完正在等候下一次请求指令的驻留连接

zabbix搭建

先安装lnmp详见文章lnmp部署

安装依赖包

[[e-mail] ~]# yum -y install net-snmp-devel libevent-devel

下载zabbix与解压

[[e-mail] ~]# wget https://cdn.zabbix.com/zabbix/sources/stable/5.0/zabbix-5.0.1.tar.gz
[[e-mail] ~]# ls
anaconda-ks.cfg  lamp  zabbix-5.0.1.tar.gz
[[e-mail] ~]# tar xf zabbix-5.0.1.tar.gz

创建zabbix用户和组

[[e-mail] ~]# useradd -r -M -s /sbin/nologin zabbix

配置zabbix数据库

[[e-mail] ~]# mysql -uroot -p123456

编译安装zabbix

[[e-mail] mysql]# cd zabbix-5.0.1
[[e-mail] zabbix-5.0.1]# ./configure --enable-server \
--enable-agent \
--with-mysql \
--with-net-snmp \
--with-libcurl \
--with-libxml2
....
[[e-mail] zabbix-5.0.1]# make install

zabbix服务端配置

[[e-mail] zabbix-5.0.1]# cd /usr/local/etc/
[[e-mail] etc]# ls
zabbix_agentd.conf    zabbix_server.conf
zabbix_agentd.conf.d  zabbix_server.conf.d
[[e-mail] etc]# vim zabbix_server.conf

DBPassword=zabbix123      //设置zabbix数据库连接密码

启动zabbix_server和zabbix_agentd
[[e-mail] ~]# zabbix_server 
[[e-mail] ~]# zabbix_agentd
[[e-mail] ~]# ss -antl

zabbix web界面安装前配置
修改/etc/php.ini的配置并重启php-fpm

[[e-mail] ~]# sed -ri 's/(post_max_size =).*/\1 16M/g' /etc/php.ini
[[e-mail] ~]# sed -ri 's/(max_execution_time =).*/\1 300/g' /etc/php.ini
[[e-mail] ~]# sed -ri 's/(max_input_time =).*/\1 300/g' /etc/php.ini
[[e-mail] ~]# sed -i '/;date.timezone/a date.timezone = Asia/Shanghai' /etc/php.ini
[[e-mail] ~]# service php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm  done

创建数据存放目录并修改目录属主和属组

[[e-mail] ~]# cd zabbix-5.0.1
[[e-mail] zabbix-5.0.1]# cp -a ui /usr/local/nginx/html/zabbix
[[e-mail] zabbix-5.0.1]# chown -R nginx.nginx /usr/local/nginx/html/zabbix/

配置apache虚拟主机

[[e-mail] ~]# vim /usr/local/nginx/conf/nginx.conf

location / {
            root   html/zabbix; //添加zabbix
            index index.php index.html index.htm;
            
location ~ \.php$ {
            root           html/zabbix; //添加zabbix
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
         }

设置zabbix/conf目录的权限，让zabbix有权限生成配置文件zabbix.conf.php

[[e-mail] ~]# chmod 777 /usr/local/nginx/html/zabbix/conf
[[e-mail] ~]# ll -d /usr/local/nginx/html/zabbix/conf
drwxrwxrwx 3 nginx nginx 94 5月  25 20:15 /usr/local/nginx/html/zabbix/conf

重载配置文件

[[e-mail] ~]# nginx -s reload
[[e-mail] ~]# ss -antl

恢复zabbix/conf目录的权限为755

[[e-mail] ~]# chmod 755 /usr/local/nginx/html/zabbix/conf
[[e-mail] ~]# ll -d /usr/local/nginx/html/zabbix/conf

            stub_status on;
            allow 192.168.179.0/24;
            deny all;
        }

配置监控脚本取出想要的数据

[[e-mail] ~]# mkdir /scripts
[[e-mail] scripts]# ls
handled.sh  Reading.sh  Writing.sh
[[e-mail] scripts]# cat handled.sh 
#!/bin/bash

status=$(curl -s http://192.168.179.128/status|awk 'NR==3{print $3}')
echo $status
[[e-mail] scripts]# cat 
handled.sh  Reading.sh  Writing.sh  
[[e-mail] scripts]# cat Reading.sh 
#!/bin/bash

status=$(curl -s http://192.168.179.128/status|awk 'NR==4{print $2}')
echo $status
[[e-mail] scripts]# cat Writing.sh 
#!/bin/bash

status=$(curl -s http://192.168.179.128/status|awk 'NR==4{print $4}')
echo $status

[[e-mail] scripts]# chmod +x *

启用自定义脚本监控功能

//添加下列三行
UnsafeUserParameters=1
UserParameter=check_handled,/bin/bash /scripts/handled.sh      
UserParameter=check_Reading,/bin/bash /scripts/Reading.sh
UserParameter=check_Writing,/bin/bash /scripts/Writing.sh

重启服务

[[e-mail] ~]# zabbix_server 
[[e-mail] ~]# zabbix_agentd
[[e-mail] ~]# zabbix_get -s 127.0.0.1 -k check_handled //测试脚本能否取出值
296
[[e-mail] ~]# zabbix_get -s 127.0.0.1 -k check_Reading
