LISTEN_IP="0.0.0.0"
LISTEN_PORT=10052
PID_FILE="/tmp/zabbix_java.pid"
START_POLLERS=5
2.修改zabbix_server文件

# sed -e '/^#/d;/^$/d' /usr/local/etc/zabbix_server.conf
LogFile=/tmp/zabbix_server.log
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
# vim/usr/local/etc/zabbix_server.conf

DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
JavaGateway=127.0.0.1
JavaGatewayPort=10052
StartJavaPollers=5
3.执行startup.sh

# sh startup.sh &
# netstat -tnlup | grep 10052
tcp 0 0 :::10052 :::* LISTEN 29326/java
4.tomcat端，安装catalina-jmx-remote.jar

# wgethttp://archive.apache.org/dist/tomcat/tomcat-7/v7.0.8/bin/extras/catalina-jmx-remote.jar
# mv catalina-jmx-remote.jar /usr/share/java/tomcat6 #yum路径
mv catalina-jmx-remote.jar /usr/local/tomcat/lib/ #源码路径
5.修改catalina.sh文件

-Dcom.sun.management.jmxremote.port=12345
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false"
#tomcat端的IP和指定JMX端口，在/bin/sh下面添加此段
7.重启服务

# /etc/init.d/tomcat6 restart
# /etc/init.d/zabbix-agent restart
8.服务端测试（jar包在附件）
1
# java -jar /root/cmdline-jmxclient-0.10.3.jar - 192.168.16.251:12345 java.lang:type=Memory NonHeapMemoryUsage
错误一：
1
