实现zabbix主动模式监控tomcat及所在主机

#1.环境准备，centos8，zabbix6.0为例
	IP           主机名                     服务
10.0.0.150  zabbixserver.tan.com  zabbix-server、zabbix-java-gateway、agent、mariadb
10.0.0.160   tomcat1.tan.com           JDK8、tomcat8、zabbix-agent
	
#2.安装zabbix-server、zabbix-java-gateway、mariadb-server
#安装zabbix-server mariadb
[root@zabbix-server ~]#rpm -Uvh https://repo.zabbix.com/zabbix/6.0/rhel/8/x86_64/zabbix-release-6.0-1.el8.noarch.rpm

[root@zabbix-server ~]#sed -i 's#https://repo.zabbix.com#https://mirrors.aliyun.com/zabbix#' /etc/yum.repos.d/zabbix.repo

[root@zabbix-server ~]#yum clean all

[root@zabbix-server ~]#dnf install zabbix-server-mysql zabbix-web-mysql zabbix-nginx-conf zabbix-sql-scripts zabbix-selinux-policy zabbix-agent

#centos8默认安装的是mariadb10.3版本，此版本zabbix需要mariadb10.5版本
[root@zabbix-server ~]#vim /etc/yum.repos.d/MariaDB.repo
[mariadb]
name = MariaDB
baseurl = https://mirrors.aliyun.com/mariadb/yum/10.5/centos8-amd64
module_hotfixes=1
gpgkey=https://mirrors.aliyun.com/mariadb/yum/RPM-GPG-KEY-MariaDB
gpgcheck=1


[root@zabbix-server ~]#dnf clean all
33 files removed
[root@zabbix-server ~]#dnf install -y mariadb mariadb-server

#3.启动mariadb
[root@zabbix-server ~]#systemctl enable --now mariadb

#4.准备数据库并授权
[root@zabbix-server ~]#mysql

#5.导入数据
[root@zabbix-server ~]#zcat /usr/share/doc/zabbix-sql-scripts/mysql/server.sql.gz | mysql -uzabbix -p zabbix
Enter password:zabbix


#6.配置zabbix-server
[root@zabbix-server ~]#grep '^[^#]' /etc/zabbix/zabbix_server.conf
ListenPort=10051
LogFile=/var/log/zabbix/zabbix_server.log
LogFileSize=0
PidFile=/run/zabbix/zabbix_server.pid

DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
JavaGateway=localhost
JavaGatewayPort=10052
StartJavaPollers=10
SNMPTrapperFile=/var/log/snmptrap/snmptrap.log
Timeout=4
LogSlowQueries=3000
AllowRoot=1
User=root
StatsAllowedIP=127.0.0.1


#7.配置前端php
[root@zabbix-server ~]#vi /etc/nginx/conf.d/zabbix.conf
server {
        listen          80;
        server_name     10.0.0.150;

#8.启动服务
[root@zabbix-server ~]#systemctl enable mariadb zabbix-server zabbix-agent nginx php-fpm --now

#9.验证服务
[root@zabbix-server ~]#systemctl is-active  zabbix-server zabbix-agent nginx
active
active
active

#10.浏览器输入http://10.0.0.150/index.php,默认登录账户密码是Admin/zabbix

#11.修改agent为主动模式
[root@zabbix-server ~]#grep "^[a-Z]" /etc/zabbix/zabbix_agentd.conf
PidFile=/run/zabbix/zabbix_agentd.pid

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


#12.安装zabbix-java-gateway
#查看zabbix_server版本
[root@zabbix-server ~]#zabbix_server -V
zabbix_server (Zabbix) 6.0.7

#安装zabbix-java-gateway
[root@zabbix-server ~]#wget https://mirrors.aliyun.com/zabbix/zabbix/6.0/rhel/8/x86_64/zabbix-java-gateway-6.0.7-1.el8.x86_64.rpm?spm=a2c6h.25603864.0.0.66a32dd56ItWnb

[root@zabbix-server ~]#yum install -y zabbix-java-gateway-6.0.7-1.el8.x86_64.rpm

#配置java-gateway
[root@zabbix-server ~]#grep "^[^#]" /etc/zabbix/zabbix_java_gateway.conf

[root@zabbix-server ~]#systemctl restart zabbix-java-gateway
[root@zabbix-server ~]#systemctl enable zabbix-java-gateway

#13.在10.0.0.160上安装tomcat并配置

#15.tomcat开启JMX监控
#解释
CATALINA_OPTS="$CATALINA_OPTS
-Dcom.sun.management.jmxremote  #启用远程监控JMX
-Dcom.sun.management.jmxremote.port=12345   #默认启动的JMX端口号，要和zabbix添加主机时候的端口一致即可
-Dcom.sun.management.jmxremote.authenticate=false  #不使用用户名密码
-Dcom.sun.management.jmxremote.ssl=false  #不使用ssl认证
-Djava.rmi.server.hostname=192.168.0.22" #tomcat主机的ip

#添加以下配置
[root@tomcat ~]#vim /usr/local/tomcat/bin/catalina.sh
CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=12345 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=10.0.0.160" 

#重启tomcat服务
[root@tomcat ~]#systemctl restart tomcat

#16.添加主机，添加jmx接口

验证JMX接口变绿

等一会就有监控数据了
