添加一个节点

# wget https://repo.zabbix.com/zabbix/4.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_4.2-1+bionic_all.deb
# dpkg -i zabbix-release_4.2-1+bionic_all.deb
# apt update
root@node2:~# apt -y install  zabbix-agent
root@node2:~# vim /etc/zabbix/zabbix_agentd.conf 
Server=173.22.90.17
ServerActive=173.22.90.17
Hostname=173.22.90.19
本机地址，不能写出否则数据采集不到
root@node2:~# systemctl start zabbix-agent
root@node2:~# systemctl enable zabbix-agent

添加主机

zabbix的日志

root@node2:~# tail -f /var/log/zabbix/zabbix_agentd.log

DebugLevel=3 这个是记录日志的级别的
root@zabbix:~# /usr/sbin/zabbix_agentd -c /etc/zabbix/zabbix_agentd.conf
root@node2:~# vim /etc/zabbix/zabbix_agentd.conf
Server=127.0.0.1
这种是通过主动模式采集的

添加zabbix-proxy

wget https://repo.zabbix.com/zabbix/4.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_4.2-1+bionic_all.deb
dpkg -i zabbix-release_4.2-1+bionic_all.deb
apt update
apt-get install zabbix-proxy-mysql

创建主动模式的数据库

create database zabbix_proxy_active character set utf8 collate utf8_bin;
MariaDB [(none)]> grant all privileges on zabbix_proxy_active.* to zabbix_proxy_active@"173.22.90.%" identified by '123456';
root@node2:~# mysql -uzabbix_proxy_active -h173.22.90.17 -p123456
