篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Zabbix对Tomcat的监控相关的知识，希望对你有一定的参考价值。
Zabbix通过java gateway 及 JMX 对Tomcat 进行监控，并实现自定义模板的导入及应用，模拟实际生产中的Tomacat性能等参数的图形监测显示。
1. Tomcat 服务器的准备
通过脚本完成Tomcat服务器的准备。
#### 上传相应的软件包和脚本，完成Tomcat的服务器准备

2. 部署java gateway服务器
Java gateway是一个独立于zabbix server和zabbix agent的组件，java gateway可以是单独一台服务器，也可以和zabbix server或者zabbix agent共用一台服务器，注意区分端口不冲突即可。本次使用一台单独的服务器，IP地址为192.168.250.118/24 。
#### 部署java gateway服务器
## 安装yum源及安装zabbix-java-gateway
[root@CentOS84-IP118 ]#rpm -Uvh https://repo.zabbix.com/zabbix/6.0/rhel/8/x86_64/zabbix-release-6.0-1.el8.noarch.rpm
[root@CentOS84-IP118 ]#dnf -y install zabbix-java-gateway
## 修改并配置zabbix_java_gateway.conf
[root@CentOS84-IP118 ]#vim /etc/zabbix/zabbix_java_gateway.conf
[root@CentOS84-IP118 ]#grep "^[a-Z]" /etc/zabbix/zabbix_java_gateway.conf
LISTEN_IP="0.0.0.0"
LISTEN_PORT=10052
PID_FILE="/var/run/zabbix/zabbix_java_gateway.pid"
START_POLLERS=8
TIMEOUT=30
[root@CentOS84-IP118 ]#
## 启动并设定开机自启
[root@CentOS84-IP118 ]#systemctl restart zabbix-java-gateway
[root@CentOS84-IP118 ]#systemctl enable zabbix-java-gateway
## 验证安装
[root@CentOS84-IP118 ]#lsof -i:10052
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
java 37771 zabbix 13u IPv6 72370 0t0 TCP *:10052 (LISTEN)
[root@CentOS84-IP118 ]#ss -tln | grep 10052
LISTEN 0 50 *:10052 *:*
3. 配置Zabbix Server调用Java Gateway
#### 配置zabbix server调用java gateway
[root@CentOS84-IP18 ]#vim /etc/zabbix/zabbix_server.conf
[root@CentOS84-IP18 ]#grep "^[a-Z]" /etc/zabbix/zabbix_server.conf
LogFile=/var/log/zabbix/zabbix_server.log
LogFileSize=0

SocketDir=/run/zabbix
DBHost=192.168.250.38
DBName=zabbix
DBUser=zabbix
DBPassword=shone123456
