4.5 修改tomcat日志catalina.out默认路径

[root@Tomcat yuanmabao]# cd /usr/tomcat/bin/
[root@Tomcat bin]# vim catalina.sh 
[tomcat@Tomcat bin]$ cat catalina.sh | sed -n '198,200p'
if [ -z "$CATALINA_OUT" ] ; then
  CATALINA_OUT=/data/Tomcat_Logs/log/catalina.out
fi

[root@Tomcat bin]# mkdir -p /data/Tomcat_Logs/log
[root@Tomcat bin]# cd /data/
[root@Tomcat data]# chown -R tomcat.tomcat Tomcat_Logs
[root@Tomcat data]# ll -d Tomcat_Logs/
drwxr-xr-x 3 tomcat tomcat 17 11月  8 16:55 Tomcat_Logs/

4.6 启动tomcat服务

[root@Tomcat data]# su - tomcat
[tomcat@Tomcat ~]$ /usr/tomcat/bin/startup.sh 

[tomcat@Tomcat ~]$ ps -ef | grep java
tomcat     7482      1 99 17:42 pts/0    00:00:01 /usr/jdk/bin/java -Djava.util.logging.config.file=/usr/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/usr/tomcat/endorsed -classpath /usr/tomcat/bin/bootstrap.jar:/usr/tomcat/bin/tomcat-juli.jar -Dcatalina.base=/usr/tomcat -Dcatalina.home=/usr/tomcat -Djava.io.tmpdir=/usr/tomcat/temp org.apache.catalina.startup.Bootstrap start
tomcat     7499   7448  0 17:42 pts/0    00:00:00 grep --color=auto java

5 Zabbix-Agent端的agent安装

5.1 安装agent命令

[root@Tomcat ~]# rpm -ivh http://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-agent-4.4.1-1.el7.x86_64.rpm

5.2 修改Zabbix-Agen端的配置文件

[root@Tomcat ~]# cd /etc/zabbix/
[root@Tomcat zabbix]# vim zabbix_agentd.conf 
[root@Tomcat zabbix]# cat -n zabbix_agentd.conf | sed -n "13p;32p;98p;106p;123p;150p;290p;309p"
    13	PidFile=/var/run/zabbix/zabbix_agentd.pid
    32	LogFile=/var/log/zabbix/zabbix_agentd.log
    98	Server=192.168.200.10
   106	ListenPort=10050
   123	StartAgents=3
   150	Hostname=Zabbix
   290	Include=/etc/zabbix/zabbix_agentd.d/*.conf
   309	UnsafeUserParameters=1

5.3 启动Zabbix-Agen端的agent服务

#启动agent命令
[root@Tomcat zabbix]# systemctl start zabbix-agent

#设置开机自启动
[root@Tomcat zabbix]# systemctl enable zabbix-agent

#查看进程
[root@Tomcat zabbix]# netstat -antup | grep zabbix_agent
tcp        0      0 0.0.0.0:10050           0.0.0.0:*               LISTEN      1557/zabbix_agentd  
tcp6       0      0 :::10050                :::*                    LISTEN      1557/zabbix_agentd  

5.4 测试zabbix server监控

#在监控端zabbix_server端进行如下操作
[root@Zabbix ~]# zabbix_get -s 192.168.200.10 -p 10050 -k "system.uptime"
1692
[root@Zabbix ~]# zabbix_get -s 192.168.200.11 -p 10050 -k "system.uptime"
1696


#参数详解
-s 是指定zabbix agent端的IP地址
-p 是指定zabbix agent端的监听端口
-k 是监控项，即item
如果有输出结果，表面zabbix server可以从zabbix agent获取数据，配置成功。

6. zabbix图形化监控简介

6.1 创建一个主机群组

6.2 创建一个主机

6.3 创建自定义监控脚本

[root@Tomcat zabbix]# cd /etc/zabbix/
[root@Tomcat zabbix]# mkdir scripts
[root@Tomcat zabbix]# cd scripts
[root@Tomcat scripts]# vim thread.sh
[root@Tomcat scripts]# cat thread.sh 
#/bin/bash

pid=`ps -ef | grep jav[a] | awk '{print $2}'`
grep -i 'thread' /proc/$pid/status | awk '{print $2}'

[root@Tomcat scripts]# chmod +x thread.sh 
[root@Tomcat scripts]# ll -d thread.sh 
-rwxr-xr-x 1 root root 112 11月 10 23:54 thread.sh

6.4 创建键值

[root@Tomcat scripts]# cd /etc/zabbix/zabbix_agentd.d
[root@Tomcat zabbix_agentd.d]# vim thread.conf
[root@Tomcat zabbix_agentd.d]# cat thread.conf 
UserParameter=thread.num,/usr/bin/sh /etc/zabbix/scripts/thread.sh

#重启zabbix才会生效
[root@Tomcat zabbix_agentd.d]# systemctl restart zabbix-agent

#检查server是否可以调取到键值
[root@Zabbix ~]# zabbix_get -s 192.168.200.11 -p 10050 -k "thread.num"
