安裝 Zabbix Agent2
$ sudo rpm -Uvh https://repo.zabbix.com/zabbix/7.0/rhel/7/x86_64/zabbix-agent2-7.0.0-release1.el7.x86_64.rpm
這時候可能會出現錯誤
-bash-4.2$ sudo rpm -Uvh https://repo.zabbix.com/zabbix/7.0/rhel/7/x86_64/zabbix-agent2-7.0.0-release1.el7.x86_64.rpm

error: Failed dependencies:
libpcre2-8.so.0()(64bit) is needed by zabbix-agent2-7.0.0-release1.el7.x86_64
缺少了套件 libpcre - 安裝 pcre2
$ sudo yum install pcre2
無法下載 rpm 套件

這個是因為缺少能下載的 wget 功能，所以再裝一下 wget
$ sudo yum install wget
安裝 pcre2 後安裝 Zabbix Agent2 - 這樣就能正確的安裝
$ sudo rpm -Uvh https://repo.zabbix.com/zabbix/7.0/rhel/7/x86_64/zabbix-agent2-7.0.0-release1.el7.x86_64.rpm

修改設定檔
$ sudo vi /etc/zabbix/zabbix_agent2.conf
然後修改下面項目，當然要把 10.1.2.3 換成你的 zabbix server
Server=10.1.2.3
ServerActive=10.1.2.3
ListenPort=10050
ListenIP=10.5.6.7
Hostname=Zabbix Client
然後啟動服務
$ sudo systemctl restart zabbix-agent2
$ sudo systemctl enable zabbix-agent2
$ sudo systemctl status zabbix-agent2
檢查 tcp 與 tcp6 的 10050 port 是否已正確 Listen
$ netstat -an | more
執行都OK，就可以到 zabbix server 上把這台 CentOS 7 的主機加入監測。
