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。
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]' 6
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"?> <zabbix_export> <version>4.0</version> <date>2019-02-11t07:29:29z</date> <groups> <group> <name>templates</name> </group> </groups> <templates> <template>

在zabbix前端页面点击配置→模板→导入:
#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
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#:
#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:
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:
#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:
当jmx图标变绿即表示配置成功:
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
#已成功获取数据
在zabbix前端页面添加主机:
监控模板选择db mysql:
zbx标准变为绿色表示成功:
在监测→最新数据页面即可查看mysql监控数据:
