环境说明
- 已关闭防火墙、selinux；
- 已通过YUM安装Zabbix，安装方法请见zabbix官网；
- 所用IP地址、角色及安装内容如下表：
| IP地址 | 角色 | 安装内容 |
|---|---|---|
| 192.168.91.134 | server | zabbix-server-mysql、zabbix-web-mysql、mariadb-server、mariadb |
| 192.168.91.133 | agent | zabbix-java-gateway、java-openjdk、apache-tomcat |
- zabbix yum源：https://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm
- apache-tomcat下载地址：http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.14/bin/apache-tomcat-9.0.14.tar.gz
原理图
- 当Zabbix-Server需要知道java应用程序的某项性能的时候，会启动自身的一个Zabbix-JavaPollers进程去连接Zabbix-JavaGateway请求数据，
- ZabbixJavagateway收到请求后使用“JMXmanagementAPI”去查询特定的应用程序，而前提是应用程序这端在开启时需要“-Dcom.sun.management.jmxremote”参数来开启JMX远程查询就行。
- Java程序会启动自身的一个简单的小程序端口12345向Zabbix-JavaGateway提供请求数据。
配置
Agent（192.168.91.134）端配置
- 安装zabbix-java-gateway（此包在zabbix YUM源中），下载apache-tomcat，解压并使用
[root@localhost ~]# yum -y install zabbix-java-gateway ##源码编译加--enable-java
[root@localhost ~]# yum -y install java-openjdk
java-1.8.0-openjdk.x86_64
[root@localhost ~]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.14/bin/apache-tomcat-9.0.14.tar.gz
[root@localhost ~]# tar -xf apache-tomcat-9.0.14.tar.gz
[root@localhost ~]# mv apache-tomcat-9.0.14 /usr/local/tomcat
- 设置环境变量
[root@localhost ~]# vim /etc/profile.d/tomcat.sh
[root@localhost ~]# source /etc/profile.d/tomcat.sh
[root@localhost ~]# echo $PATH
/usr/local/tomcat/bin/:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
- 启动tomcat
[root@localhost ~]# catalina.sh start
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
- 开启tomcat的远程jvm配置文件
[root@localhost tomcat]# vim /usr/local/tomcat/bin/catalina.sh
CATALINA_OPTS="$CATALINA_OPTS
## 启用远程监控JMX
-Dcom.sun.management.jmxremote
## jmx启用远程端口，Zabbix添加时必须一致
-Dcom.sun.management.jmxremote.port=12345
## 不开启用户认证
-Dcom.sun.management.jmxremote.authenticate=false
## 不启用ssl加密传输
-Dcom.sun.management.jmxremote.ssl=false
## 运行tomcat主机的IP地址
-Djava.rmi.server.hostname=192.168.91.134"
- 重新启动tomcat
[root@localhost tomcat]# catalina.sh stop
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
[root@localhost tomcat]# catalina.sh start
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
- 启动zabbix-java-gateway服务
[root@localhost tomcat]# systemctl restart zabbix-java-gateway
[root@localhost tomcat]# ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 50 :::10052 :::*
Server（192.168.91.133）端配置
- 修改zabbix_server.conf配置文件
[root@localhost ~]# vim /etc/zabbix/zabbix_server.conf
## java gateway地址
JavaGateway=192.168.91.134
## java gateway默认端口10052
JavaGatewayPort=10052
## 启动进程轮询java gateway
StartJavaPollers=5
- 重启zabbix-server服务
[root@localhost ~]# systemctl restart zabbix-server
Zabbix Web端配置
