環境說明

• 已關閉防火牆、selinux；
• 已通過YUM安裝Zabbix，安裝方法請見zabbix官網；
• 所用IP地址、角色及安裝內容如下表：

• zabbix yum源：https://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm
• apache-tomcat下載地址：http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.14/bin/apache-tomcat-9.0.14.tar.gz

原理圖

• 當Zabbix-Server需要知道java應用程式的某項效能的時候，會啟動自身的一個Zabbix-JavaPollers程序去連線Zabbix-JavaGateway請求資料，
• ZabbixJavagateway收到請求後使用“JMXmanagementAPI”去查詢特定的應用程式，而前提是應用程式這端在開啟時需要“-Dcom.sun.management.jmxremote”引數來開啟JMX遠端查詢就行。
• Java程式會啟動自身的一個簡單的小程式埠12345向Zabbix-JavaGateway提供請求資料。

配置

Agent（192.168.91.134）端配置

• 安裝zabbix-java-gateway（此包在zabbix YUM源中），下載apache-tomcat，解壓並使用

[[email protected]
 
 ~]# yum -y install zabbix-java-gateway    ##原始碼編譯加--enable-java
[[email protected] ~]# yum -y install java-openjdk
java-1.8.0-openjdk.x86_64
[[email protected] ~]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.14/bin/apache-tomcat-9.0.14.tar.gz
[[email protected] ~]# tar -xf apache-tomcat-9.0.14.tar.gz 
[[email protected] ~]# mv apache-tomcat-9.0.14 /usr/local/tomcat

• 設定環境變數

[[email protected] ~]# vim /etc/profile.d/tomcat.sh
[[email protected] ~]# source /etc/profile.d/tomcat.sh
[[email protected] ~]# echo $PATH
/usr/local/tomcat/bin/:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin

• 啟動tomcat

[[email protected] ~]# 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.

• 開啟tomcat的遠端jvm配置檔案

[[email protected] tomcat]# vim /usr/local/tomcat/bin/catalina.sh
CATALINA_OPTS="$CATALINA_OPTS
## 啟用遠端監控JMX
-Dcom.sun.management.jmxremote
## jmx啟用遠端埠，Zabbix新增時必須一致
-Dcom.sun.management.jmxremote.port=12345
## 不開啟使用者認證
-Dcom.sun.management.jmxremote.authenticate=false
## 不啟用ssl加密傳輸
-Dcom.sun.management.jmxremote.ssl=false
## 執行tomcat主機的IP地址
-Djava.rmi.server.hostname=192.168.91.134"

• 重新啟動tomcat

[[email protected] 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
[[email protected] 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.

• 啟動zabbix-java-gateway服務

[[email protected] tomcat]# systemctl restart zabbix-java-gateway
[[email protected] 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配置檔案

[[email protected] ~]# vim /etc/zabbix/zabbix_server.conf
## java gateway地址
JavaGateway=192.168.91.134
## java gateway預設埠10052
JavaGatewayPort=10052
## 啟動程序輪詢java gateway
StartJavaPollers=5

• 重啟zabbix-server服務

[[email protected] ~]# systemctl restart zabbix-server
