# 简述 #

tomcat需要jdk（java）依赖，zabbix有独立的zabbix-java-gateway监控java  
程序；监控tomcat流程如下：

*  zabbix-web用于web界面显示，没有特殊含义；
 *  zabbix-server启用javapollers进程去链接zabbix-java-gateway去请求数据（修改配置文件可实现），Zabbix-Javagateway就相当于一个代理，它负责收集客户端tomcat数据；
 *  zabbix-java-gateway开启JMX功能，用于远程连接tomcat，收集tomcat信息；
 *  tomcat配置文件添加JMX参数

实验环境

## tomcat添加JMX参数 ##

修改catalina.sh文件  
添加以下内容

> 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=127.0.0.1"

注意格式问题，不要去复制上面的，看别人的博客都是直接放在了代码片里面，自己跟着做坑死了，按照下面的来

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=127.0.0.1"

重启tomat  
保证12345端口可以正常开启

[root@localhost ~]# sh tomcat.sh restart
    [root@localhost ~]# netstat -anpt | grep 12345
    tcp6       0      0 :::12345                :::*                    LISTEN      3049/java           
    [root@localhost ~]# netstat -anpt | grep 8080
    tcp6       0      0 :::8080                 :::*                    LISTEN      3049/java           
    tcp6       0      0 ::1:45152               ::1:8080                TIME_WAIT   -

## 配置zabbix服务端 ##

安装`zabbix-java-gateway`

#安装
    yum -y install zabbix-java-gateway
    #启动
    systemctl start zabbix-java-gateway
    #开机启动
    systemctl enable zabbix-java-gateway

> zabbix-server默认工作在10051端口，zabbix-agent默认工作在10050端口,zabbix-java-ggateway默认工作在10052

修改`zabbix-java-gateway`配置文件

[root@localhost ~]# grep -Ev '^#|^$' /etc/zabbix/zabbix_java_gateway.conf 
    LISTEN_PORT=10052
    PID_FILE="/var/run/zabbix/zabbix_java.pid"
    START_POLLERS=5 #设置启动多个线程，这里和server段相同
    TIMEOUT=3
    #添加以下参数开启JMX功能
    uncomment to enable remote monitoring of the standard JMX objects on the Zabbix Java Gateway itself
    JAVA_OPTIONS="$JAVA_OPTIONS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=12345 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false"

修改`zabbix-server`配置文件

[root@localhost ~]# grep -Ev '^#|^$' /etc/zabbix/zabbix_server.conf 
    LogFile=/var/log/zabbix/zabbix_server.log
    LogFileSize=0
    PidFile=/var/run/zabbix/zabbix_server.pid
    SocketDir=/var/run/zabbix
    DBName=zabbix
    DBUser=zabbix
    DBPassword=123.com
    JavaGateway=192.168.10.7
    JavaGatewayPort=10052
    StartJavaPollers=5  #和zabbix-java-gateway的线程一致
    SNMPTrapperFile=/var/log/snmptrap/snmptrap.log
    Timeout=4
    AlertScriptsPath=/usr/lib/zabbix/alertscripts
    ExternalScripts=/usr/lib/zabbix/externalscripts
    LogSlowQueries=3000

重启zabbix服务

systemctl restart zabbix-server
    systemctl restart zabbix-java-gateway

tomcat添加`catalina-jmx-remote.jar`  
JMX远程生命周期侦听器，没有必要性，可以添加也可以不添加  
要找到对应tomcat版本的catalina-jmx-remote.jar，访问 [tomcat各个版本][tomcat]

下载完成以后要放到`tomcat8/lib`

wget http://archive.apache.org/dist/tomcat/tomcat-8/v8.5.55/bin/extras/catalina-jmx-remote.jar
    mv catalina-jmx-remote.jar /usr/local/tomcat8/lib/

重启tomcat

sh tomcat.sh restart

关闭防火墙或者开发端口

[root@localhost ~]# systemctl stop firewalld.service 
    [root@localhost ~]# setenforce 0

## 测试 ##

下载cmdline-jmxclient-0.10.3.jar

zabbix-web界面添加主机  
我这里zabbix-java-gateway和zabbix-server在一台主机，可以分开，分开的话就填写对应的ip即可

添加模板

稍等一会儿，JMX就会绿起来
