zabbix監(jiān)控遠(yuǎn)程主機(jī)

在Zabbix服務(wù)器上安裝Zabbix代理程序

在遠(yuǎn)程主機(jī)上安裝Zabbix代理程序。安裝方式取決于操作系統(tǒng)，可以從Zabbix官網(wǎng)上下載相應(yīng)的安裝包進(jìn)行安裝。

監(jiān)控agent1

在agent1上安裝agent

yum install zabbix-agent

另外在zabbix server上要關(guān)閉防火墻和selinux，防止zabbix server無(wú)法監(jiān)聽(tīng),這是臨時(shí)關(guān)閉

setenforce 0

永久關(guān)閉，進(jìn)入配置文件修改，重啟主機(jī)即可

 vim /etc/selinux/config
 
SELINUX=disabled

 

在Zabbix服務(wù)器上創(chuàng)建一個(gè)新的主機(jī)，將遠(yuǎn)程主機(jī)添加為被監(jiān)控的主機(jī)

首先來(lái)查看一下遠(yuǎn)程主機(jī)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機(jī)信息

點(diǎn)擊添加，點(diǎn)擊更新

配置Zabbix代理程序以允許與Zabbix服務(wù)器通信。在代理程序的配置文件中，將“Server”和“ServerActive”參數(shù)設(shè)置為Zabbix服務(wù)器的IP地址

配置zabbix-agent端的配置文件,啟動(dòng)服務(wù)并做成開(kāi)機(jī)自動(dòng)啟動(dòng)

vim /etc/zabbix/zabbix_agentd.conf

97 Server=                修改成zabbix監(jiān)控服務(wù)器的IP



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


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

報(bào)錯(cuò)：

沒(méi)有連接上，檢查下

無(wú)法連接服務(wù)器的10050端口

查看服務(wù)器日志：

可能agent主機(jī)端口被防火墻攔截了，關(guān)閉

systemctl stop firewalld && systemctl disable firewalld
