一,zabbix被動模式和主動模式的區別?
zabbix-agent默認的模式是被動模式,
zabbix agent被動地接受zabbix server發來的指令,
獲取數據后再返回給zabbix server
zabbix server會周期性地向agent索取數據
主動模式:
zabbix agent 主動采集數據並返回給zabbix server,
不需要zabbix server 的另行干預
兩者的性能比較:
被動模式的缺點:
會增加zabbix server的工作量,在有大量的服務器需要監控時,
zabbix server不能及時獲取到最新的數據
主動模式能一定程度上減輕zabbix server的壓力
說明:zabbix5.0在linux服務器上安裝,參見:

二,受控端上(運行zabbix-agent)的配置:
說明:
受控端(zabbix-agent)服務器ip: 121.122.123.87
控制端(zabbix-server)服務器ip: 121.122.123.47
1,受控端上查看os版本
[root@web2 ~]# cat /etc/redhat-release CentOS release 6.5 (Final)
2,把主控機器的ip添加到被監控機器的防火牆,
至少要允許主控機器訪問10050端口
[root@web2 ~]# vi /etc/sysconfig/iptables
添加一行:例如:
-I INPUT -p tcp -s 121.122.123.47 --dport 10050 -j ACCEPT
然后重新加載iptables
[root@web2 ~]# service iptables reload
iptables: Trying to reload firewall rules: [ OK ]
3,下載zabbix-agent
我們從清華的鏡像站上下載,
地址:
https://mirrors.tuna.tsinghua.edu.cn/zabbix/
注意和server端保持版本一致
說明:因為不需要lnmp環境,我們選擇下載rpm包后安裝
創建安裝包的保存目錄
[root@web2 ~]# mkdir -p /usr/local/source/zabbix [root@web2 ~]# cd /usr/local/source/zabbix
下載:
[root@web2 zabbix]# wget https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/5.0/rhel/6/x86_64/zabbix-agent-5.0.0-1.el6.x86_64.rpm
4,安裝zabbix-agent
[root@web2 zabbix]# rpm -ivh zabbix-agent-5.0.0-1.el6.x86_64.rpm warning: zabbix-agent-5.0.0-1.el6.x86_64.rpm: Header V4 RSA/SHA512 Signature, key ID a14fe591: NOKEY Preparing... ########################################### [100%] 1:zabbix-agent ########################################### [100%]
5,配置:
編輯配置文件
[root@web2 zabbix]# vi /etc/zabbix/zabbix_agentd.conf
配置的內容:
Server=121.122.123.47 ListenPort=10050 StartAgents=0 ServerActive=121.122.123.47 Hostname=web2
說明:
Server: 被動模式訪問的zabbix-server的ip
ServerActive: 主動模式訪問的zabbix-server的ip
StartAgents :zabbix_agentd用來處理被動檢查的實例數量,
如果設置為0,則禁用被動模式檢查而且agent不再監聽任何tcp端口
附原說明:
### Option: StartAgents # Number of pre-forked instances of zabbix_agentd that process passive checks. # If set to 0, disables passive checks and the agent will not listen on any TCP port.
6,配置完成后,啟動服務:
[root@web2 ~]# service zabbix-agent start
Starting Zabbix agent: [ OK ]
7,查看zabbix-agent的版本:
[root@web2 zabbix]# /usr/sbin/zabbix_agentd --version zabbix_agentd (daemon) (Zabbix) 5.0.0 Revision 9665d62db0 11 May 2020, compilation time: May 11 2020 07:27:56 Copyright (C) 2020 Zabbix SIA License GPLv2+: GNU GPL version 2 or later <http://gnu.org/licenses/gpl.html>.

三,zabbix-server端的配置:
1,添加到防火牆:
說明:服務端所在的機器的os版本是centos8,使用firewalld,
不再是使用iptables
下面命令的作用:把受控端ip和要訪問的主控端的端口加入到防火牆
[root@blog ~]# firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="121.122.123.87" port protocol="tcp" port="10051" accept' success [root@blog ~]# firewall-cmd --reload success
2,添加主機:
左側菜單->配置->主機->創建主機
見截圖:
主機頁面:
主機名:web2
客戶端:121.122.123.87
端口: 10050
模板頁面:
選擇:
template os linux by zabbix agent active
說明:注意要選擇帶active的模板
完成后點 添加 按鈕
五,查看服務端的zabbix-server版本
[root@blog zabbix-5.0.0]# /usr/local/soft/zabbx-5.0.0/sbin/zabbix_server --version zabbix_server (Zabbix) 5.0.0 Revision 9665d62db0 11 May 2020, compilation time: May 17 2020 09:37:03 Copyright (C) 2020 Zabbix SIA License GPLv2+: GNU GPL version 2 or later <http://gnu.org/licenses/gpl.html>.
