zabbix监控远程主机

在Zabbix服务器上安装Zabbix代理程序

在远程主机上安装Zabbix代理程序。安装方式取决于操作系统，可以从Zabbix官网上下载相应的安装包进行安装。

监控agent1

在agent1上安装agent

yum install zabbix-agent

另外在zabbix server上要关闭防火墙和selinux，防止zabbix server无法监听,这是临时关闭

setenforce 0

永久关闭，进入配置文件修改，重启主机即可

 vim /etc/selinux/config
 
SELINUX=disabled

 

在Zabbix服务器上创建一个新的主机，将远程主机添加为被监控的主机

首先来查看一下远程主机agent1的ip

[root@agent1 ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:63:ac:b4 brd ff:ff:ff:ff:ff:ff
    inet 192.168.126.142/24 brd 192.168.126.255 scope global noprefixroute dynamic ens33
       valid_lft 1123sec preferred_lft 1123sec
    inet6 fe80::3615:945b:279f:489e/64 scope link noprefixroute
       valid_lft forever preferred_lft forever

添加模板才能查看主机信息

点击添加，点击更新

配置Zabbix代理程序以允许与Zabbix服务器通信。在代理程序的配置文件中，将“Server”和“ServerActive”参数设置为Zabbix服务器的IP地址

配置zabbix-agent端的配置文件,启动服务并做成开机自动启动

vim /etc/zabbix/zabbix_agentd.conf

97 Server=                修改成zabbix监控服务器的IP



[root@agent1 ~]# systemctl restart zabbix-agent
[root@agent1 ~]# systemctl enable zabbix-agent 


[root@agent1 ~]# lsof -i:10050 

报错：

没有连接上，检查下

无法连接服务器的10050端口

查看服务器日志：

可能agent主机端口被防火墙拦截了，关闭

systemctl stop firewalld && systemctl disable firewalld

成功连接
