## 实验环境 ##

zabbix-server：
    centos 7
    192.168.14.216
    
    nginx
    centos7
    192.168.14.210

## 介绍： ##

zabbix默认带有两个nginx的模板，可以直接链接模板使用。本文主要介绍根据实际情况自定义一些监控选项

## 一、Nginx（192.168.14.210） ##

1、安装

#配置epel源
    [root@nginx ~]# vi /etc/yum.repos.d/epel.repo
    [nginx]
    name=aliyun epel
    baseurl=http://mirrors.aliyun.com/epel/7Server/x86_64/
    gpgcheck=0
    #安装nginx
    [root@nginx ~]# yum install -y nginx
    #安装zabbix-agent
    [root@nginx ~]# rpm -ivh http://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm
    [root@nginx ~]# yum install -y zabbix-agent

2、修改nginx配置文件，为了不影响默认/，添加新的/status

[root@nginx ~]# vim /etc/nginx/nginx.conf
            location /status {
               stub_status on;
               access_log off;
               allow 127.0.0.1;
               deny all;
            }

3、查看监控内容

![20191118172609424.png][]

Active  connections：当前所有处于打开状态的活动连接数(TCP连接数，即三次握手四次挥手次数)  
accepts ：已经接收连接数  
handled ： 已经处理过的连接数  
requests ： 已经处理过的请求数，在保持连接模式下，请求数量可能会大于连接数量  
Reading: 正处于接收请求的连接数  
Writing: 请求已经接收完成，处于响应过程的连接数  
Waiting : 保持连接模式，处于活动状态的连接数

4、添加nginx监控选项

#拷贝自带的mysql配置文件并修改为nginx
    [root@nginx ~]# cd /etc/zabbix/zabbix_agentd.d/
    [root@nginx zabbix_agentd.d]# cp userparameter_mysql.conf userparameter_nginx.conf
    
    #删除有关mysql数据，添加nginx监控选项
    [root@nginx zabbix_agentd.d]# vi userparameter_nginx.conf 
    UserParameter=nginx.active,curl -s http://127.0.0.1/status  2>/dev/null| grep 'Active' | awk '{print $NF}'
    UserParameter=nginx.reading,curl -s http://127.0.0.1/status 2>/dev/null| grep 'Reading' | awk '{print $2}'
    UserParameter=nginx.writing,curl -s http://127.0.0.1/status 2>/dev/null| grep 'Writing' | awk '{print $4}'
    UserParameter=nginx.waiting,curl -s http://127.0.0.1/status 2>/dev/null| grep 'Waiting' | awk '{print $6}'
    UserParameter=nginx.accepts,curl -s http://127.0.0.1/status 2>/dev/null| awk NR==3 | awk '{print $1}'
    UserParameter=nginx.handled,curl -s http://127.0.0.1/status 2>/dev/null| awk NR==3 | awk '{print $2}'
    UserParameter=nginx.requests,curl -s http://127.0.0.1/status 2>/dev/null| awk NR==3 | awk '{print $3}'

5、开启服务

[root@nginx ~]# systemctl start nginx
    [root@nginx ~]# systemctl start zabbix-agent

6、防火墙允许端口访问

[root@nginx ~]# firewall-cmd --permanent --zone=public --add-port=80/tcp 
    [root@nginx ~]# firewall-cmd --permanent --zone=public --add-port=10050/tcp 
    [root@nginx ~]# firewall-cmd  --reload

## 二、zabbix-server（192.168.14.216） ##

1、检查是否安装zabbi\_get

[root@zabbix_server ~]# docker ps -a
    CONTAINER ID        IMAGE                                          COMMAND                  CREATED             STATUS                  PORTS                                      NAMES
    e2e2a132cd5d        zabbix/zabbix-agent:centos-latest              "/sbin/tini -- /usr/…"   25 hours ago        Up 25 hours                                                        zabbix_zabbix-agent_1
    f1e1da5d9083        zabbix/zabbix-web-apache-mysql:centos-latest   "docker-entrypoint.sh"   25 hours ago        Up 25 hours (healthy)   0.0.0.0:80->80/tcp, 0.0.0.0:443->443/tcp   zabbix_zabbix-web-apache-mysql_1
    f96412915d59        zabbix/zabbix-server-mysql:centos-latest       "/sbin/tini -- /usr/…"   25 hours ago        Up 25 hours             0.0.0.0:10051->10051/tcp                   zabbix_zabbix-server_1
    dd4a1123fa5d        mysql:5.7                                      "docker-entrypoint.s…"   30 hours ago        Up 25 hours                                                        zabbix_mysql-server_1
    9a4c101679e2        zabbix/zabbix-snmptraps:centos-latest          "/usr/bin/supervisor…"   30 hours ago        Up 25 hours             0.0.0.0:162->162/udp                       zabbix_zabbix-snmptraps_1
    [root@zabbix_server ~]# docker exec -it zabbix_zabbix-server_1 /bin/bash
    [root@f96412915d59 zabbix]# zabbix_get -s 192.168.14.210 -p 10050 -k 'nginx.active'
    1

2、添加监控选项（依次创建七个监控选项）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 2][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 3][]

3、查看创建

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 4][]

4、创建图形

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 5][]

5、添加图形监控项

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 6][]

6、查看图形结果
