这篇文章主要介绍“zabbix监控Nginx/Tomcat/MySQL的方法”的相关知识，小编通过实际案例向大家展示操作过程，操作方法简单快捷，实用性强，希望这篇“zabbix监控Nginx/Tomcat/MySQL的方法”文章能帮助大家解决问题。

zabbix监控nginx

a机器：zabbix服务端（192.168.234.128） b机器：zabbix客户端（192.168.234.125）

在b机器（zabbix客户端）操作：

编辑nginx虚拟主机配置文件：

[root@centos ~]# vi /etc/nginx/conf.d/default.conf

在server{}中添加以下内容：

 location /nginx_status
 {
  stub_status on;
  access_log off;
  allow 127.0.0.1;
  deny all;
 }

重载nginx配置：

[root@centos ~]# nginx -s reload

测试：

[root@centos ~]# curl http://127.0.0.1/nginx_status
active connections: 1 
server accepts handled requests
 3 3 3 
reading: 0 writing: 1 waiting: 0

#nginx状态信息已显示

状态说明：

添加监控脚本:

vi /usr/local/sbin/ngx_status.sh

添加以下内容：

#!/bin/bash
url="http://127.0.0.1/nginx_status"
curl=/usr/bin/curl

# 检测nginx进程是否存在
function ping {
 /sbin/pidof nginx | wc -l 
}
# 检测nginx性能
function active {
 $curl $url 2>/dev/null| grep 'active' | awk '{print $nf}'
}
function reading {
 $curl $url 2>/dev/null| grep 'reading' | awk '{print $2}'
}
function writing {
 $curl $url 2>/dev/null| grep 'writing' | awk '{print $4}'
}
function waiting {
 $curl $url 2>/dev/null| grep 'waiting' | awk '{print $6}'
}
function accepts {
 $curl $url 2>/dev/null| awk nr==3 | awk '{print $1}'
}
function handled {
 $curl $url 2>/dev/null| awk nr==3 | awk '{print $2}'
}
function requests {
 $curl $url 2>/dev/null| awk nr==3 | awk '{print $3}'
}
$1

添加权限：

[root@centos ~]# chmod 755 /usr/local/sbin/ngx_status.sh

编辑zabbix_agent配置文件：

[root@centos ~]# vi /etc/zabbix/zabbix_agentd.conf

在option：userparameter处添加：userparameter=nginx.status[*],/usr/local/sbin/ngx_status.sh $1

重启服务：

[root@centos ~]# systemctl restart zabbix-agent

在a机器（服务端）测试：

[root@zabbix ~]# zabbix_get -s 192.168.234.125 -k 'nginx.status[accepts]'

在本机创建.xml文件并添加以下内容：（文件名称自定义）

<?xml version="1.0" encoding="utf-8"?>

在zabbix前端页面点击配置→模板→导入：

zabbix监控Nginx/Tomcat/MySQL的方法

#导入刚才创建的xml文件即可

导入成功后在主机列表页面选择被监控的机器（b机器）链接该模板即可开始监控nginx

zabbix监控tomcat

a机器：zabbix服务端（192.168.234.128） b机器：zabbix客户端（192.168.234.125）

在a机器安装zabbix-java-gateway：

[root@zabbix ~]# wget https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-java-gateway-4.0.14-1.el7.x86_64.rpm

[root@zabbix ~]# yum -y localinstall zabbix-java-gateway-4.0.14-1.el7.x86_64.rpm

编辑gateway配置文件：

[root@zabbix ~]# vi /etc/zabbix/zabbix_java_gateway.conf

去掉listen_ip、listen_port(监听端口)、start_pollers(进程数)的注释符号#：

zabbix监控Nginx/Tomcat/MySQL的方法

#listen_ip定义被监控机器的地址，不指定默认监听全部机器

编辑server配置文件：

[root@zabbix ~]# vi /etc/zabbix/zabbix_server.conf

定义以下3个配置参数：

zabbix监控Nginx/Tomcat/MySQL的方法

启动zabbix-java-gateway服务：

[root@zabbix ~]# systemctl start zabbix-java-gateway

重启zabbix-server服务：

[root@zabbix ~]# systemctl restart zabbix-server

查看监听端口：

[root@zabbix ~]# netstat -lntp |grep java
tcp6  0  0 :::10052    :::*     listen  8706/java

开启jmx

在b机器编辑tomcat配置文件：

[root@centos ~]# vi /usr/local/tomcat/bin/catalina.sh

添加以下内容：

export catalina_opts="$catalina_opts -dcom.sun.management.jmxremote
-djava.rmi.server.hostname=192.168.234.125
-dcom.sun.management.jmxremote.port=9999
-dcom.sun.management.jmxremote.ssl=false
-dcom.sun.management.jmxremote.authenticate=false"

#hostname定义b机器地址，端口9999（默认12345）

重启tomcat：

[root@centos ~]# /usr/local/tomcat/bin/shutdown.sh 

[root@centos ~]# /usr/local/tomcat/bin/startup.sh

查看监听端口9999：

[root@centos ~]# netstat -lntp |grep 9999
tcp6  0  0 :::9999     :::*     listen  25861/java

进入zabbix前端页面添加主机：

zabbix监控Nginx/Tomcat/MySQL的方法

#与普通情况添加监控主机不同，监控b机器的tomcat需要配置jmx接口

模板链接jmx相关的两个模板：

zabbix监控Nginx/Tomcat/MySQL的方法

当jmx图标变绿即表示配置成功：

zabbix监控Nginx/Tomcat/MySQL的方法

zabbix监控mysql

a机器：zabbix服务端（192.168.234.128） b机器：zabbix客户端（192.168.234.125）

zabbix_agent定义mysql监控的配置文件：/etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf

在b机器登录mysql创建用户：

mysql> grant usage,process,replication client on *.* to zamysql@'localhost' identified by 'zamysql';

创建配置文件指定的目录：

[root@centos ~]# mkdir /var/lib/zabbix

创建my.cnf文件：

[root@centos ~]# vi /var/lib/zabbix/.my.cnf

#需要注意该文件是隐藏文件

添加以下内容：

[mysql]
host=localhost
user=zamysql
password='zamysql'
socket=/tmp/mysql.sock

[mysqladmin]
host=localhost
user=zamysql
password='zamysql'
socket=/tmp/mysql.sock

在a机器测试：

[root@zabbix ~]# zabbix_get -s 192.168.234.125 -p 10050 -k mysql.ping
1
[root@zabbix ~]# zabbix_get -s 192.168.234.125 -p 10050 -k mysql.version
mysql ver 14.14 distrib 5.6.43, for linux-glibc2.12 (x86_64) using editline wrapper
[root@zabbix ~]# zabbix_get -s 192.168.234.125 -p 10050 -k mysql.size
10240
