一.安装JDK环境
1>.更换阿里云的软件源
[root@zabbix_gateway250.yinzhengjie.org.cn ~]# vim /etc/apt/sources.list [root@zabbix_gateway250.yinzhengjie.org.cn ~]# [root@zabbix_gateway250.yinzhengjie.org.cn ~]# cat /etc/apt/sources.list deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse [root@zabbix_gateway250.yinzhengjie.org.cn ~]# [root@zabbix_gateway250.yinzhengjie.org.cn ~]# apt-get update
2>.安装JDK
[root@tomcat250.yinzhengjie.org.cn ~]# apt-get -y install openjdk-8-jdk
3>.以二进制方式安装JDK

二.配置tomcat支持JMX功能
1>.基于二进制方式部署tomcat
博主推荐阅读: https://www.cnblogs.com/yinzhengjie/p/12199468.html
2>.自定义tomcat测试首页
[root@tomcat250.yinzhengjie.org.cn ~]# echo "<h1>Jason Yin bolg is [https://www.cnblogs.com/yinzhengjie/].</h1>" > /yinzhengjie/softwares/tomcat/webapps/ROOT/index.html [root@tomcat250.yinzhengjie.org.cn ~]# [root@tomcat250.yinzhengjie.org.cn ~]# /yinzhengjie/softwares/tomcat/bin/catalina.sh start
3>.配置tomcat支持JMX功能(/yinzhengjie/softwares/tomcat/bin/catalina.sh)
#Add by yinzhengjie for enable JMX 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=172.200.5.250" 温馨提示: -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=172.200.5.250": tomcat主机自己的IP地址，不要写zabbix服务器的地址。
4>.重启tomcat并确认tomcat服务
[root@tomcat250.yinzhengjie.org.cn ~]# ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 127.0.0.53%lo:53 0.0.0.0:* LISTEN 0 128 0.0.0.0:22 0.0.0.0:* LISTEN 0 100 *:8080 *:* LISTEN 0 128 [::]:22 [::]:* LISTEN 0 1 [::ffff:127.0.0.1]:8005 *:* [root@tomcat250.yinzhengjie.org.cn ~]# [root@tomcat250.yinzhengjie.org.cn ~]# [root@tomcat250.yinzhengjie.org.cn ~]# /yinzhengjie/softwares/tomcat/bin/catalina.sh stop Using CATALINA_BASE: /yinzhengjie/softwares/tomcat Using CATALINA_HOME: /yinzhengjie/softwares/tomcat Using CATALINA_TMPDIR: /yinzhengjie/softwares/tomcat/temp Using JRE_HOME: /usr Using CLASSPATH: /yinzhengjie/softwares/tomcat/bin/bootstrap.jar:/yinzhengjie/softwares/tomcat/bin/tomcat-juli.jar [root@tomcat250.yinzhengjie.org.cn ~]# [root@tomcat250.yinzhengjie.org.cn ~]# [root@tomcat250.yinzhengjie.org.cn ~]# ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 127.0.0.53%lo:53 0.0.0.0:* LISTEN 0 128 0.0.0.0:22 0.0.0.0:* LISTEN 0 128 [::]:22 [::]:* [root@tomcat250.yinzhengjie.org.cn ~]# [root@tomcat250.yinzhengjie.org.cn ~]#
三.使用JConsole连接tomcat jmx进行测试
1>.window操作系统安装JAVA

2>.如下图所示,运行JConsole并配置tomcat的JMX连接地址及端口，并点击"连接"
3>.点击"不安全的连接"
4>.查看你关心的监控数据
