注意：Zabbix監控tomcat需要通過JMX方式監控，JMX監控方式依賴JAVA環境，在此安裝JDK1.8，以下是JDK下載頁面，下載完成上傳到服務器

Tomcat端更改配置文件
被監控端tomcat也需要更改配置文件
[root@Zabbix_Client_56 /]# vim /usr/local/tomcat/bin/catalina.sh
#在catalina文件中添加以下內容，端口爲12345，hostanme爲tomcat被監控的IP地址
CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.port=12345 -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=192.168.56.8"
下載相應監控JMX的jar包
注意：Tomcat可以通過jmx進行監控，默認是沒有開啓。在 tomcat 下載頁面 Extras 類別中下載 JMX Remote jar 二進制包。放在 tomcat的lib目錄下面。Jar包名稱爲catalina-jmx-remote.jar，該jar包需要相應版本需要對應tomcat版本
http://archive.apache.org/dist/tomcat/ #該鏈接是下載catalina-jmx-remote.jar的鏈接，進去找到相應版本進行下載
[root@Zabbix_Client_56 /]# /usr/local/tomcat/bin/version.sh #查看tomcat版本

Zabbix頁面添加對tomcat的監控需要通過jmx方式
先暫時添加zabbix默認自帶的JMX模版，回頭根據需求自己寫監控Tomcat監控鍵值，創建模版
添加過之後可以看到通過JMX的變爲了綠色
zabbix自帶的監控的監控項好多都是tomcat裏面沒有的，所以會出現好多找不到鍵值等報錯，建議自己寫對tomcat監控的鍵值，自定模版
