2. zabbix agent配置文件

[root@CentOS8 yum.repos.d]# cat /etc/zabbix/zabbix_agentd.conf | egrep -v "^$|^#"
# 被动检查相关配置
PidFile=/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Server=10.211.55.13ListenPort=10050StartAgents=3
Hostname=10.211.55.10
Include=/etc/zabbix/zabbix_agentd.d/*.conf

3. 重启zabbix agent

[root@CentOS8 yum.repos.d]# systemctl  restart zabbix-agent.service
[root@CentOS8 yum.repos.d]# systemctl  status zabbix-agent.service
● zabbix-agent.service - Zabbix AgentLoaded: loaded (/usr/lib/systemd/system/zabbix-agent.service; disabled; vendor preset: disabled)Active: active (running) since Tue 2024-07-09 20:37:01 CST; 5s agoProcess: 55029 ExecStart=/usr/sbin/zabbix_agentd -c $CONFFILE (code=exited, status=0/SUCCESS)Main PID: 55031 (zabbix_agentd)Tasks: 6 (limit: 4922)Memory: 3.6MCGroup: /system.slice/zabbix-agent.service├─55031 /usr/sbin/zabbix_agentd -c /etc/zabbix/zabbix_agentd.conf├─55032 /usr/sbin/zabbix_agentd: collector [idle 1 sec]├─55033 /usr/sbin/zabbix_agentd: listener #1 [waiting for connection]├─55034 /usr/sbin/zabbix_agentd: listener #2 [waiting for connection]├─55035 /usr/sbin/zabbix_agentd: listener #3 [waiting for connection]└─55036 /usr/sbin/zabbix_agentd: active checks #1 [idle 1 sec]Jul 09 20:37:01 CentOS8.5-epbf systemd[1]: Starting Zabbix Agent...

4. 验证zabbix agent

验证zabbix-agent进程是否存在，端口是否监听以及日志是否有异常

[root@CentOS8 yum.repos.d]# ps -ef| grep zabbix
zabbix     55031       1  0 20:37 ?        00:00:00 /usr/sbin/zabbix_agentd -c /etc/zabbix/zabbix_agentd.conf

5. zabbix web添加被监控主机

6. 验证主机监控数据
