1、服务器环境
- 云主机：青云云主机
- 云主机操作系统
- Zabbix Server：3.2
- 监控方式：被动监控
2、操作步骤
以用户ubuntu登录到云主机，执行以下操作。
2-1、添加zabbix-agent资源库
执行一下命令，添加zabbix-agent资源库：
wget http://repo.zabbix.com/zabbix/3.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_3.2-1+xenial_all.deb sudo dpkg -i zabbix-release_3.2-1+xenial_all.deb sudo apt-get update 2-2、安装zabbix-agent
执行以下命令，安装zabbix-agent：
sudo apt-get install -y zabbix-agent 2-3、配置zabbix-agent
执行以下命令，配置zabbix-agent，这里采用是被动监控模式：
sudo vi /etc/zabbix/zabbix_agentd.conf 配置zabbix server 的IP以及该云主机的host name，主要配置两项：
- Server=xx.xx.xx.xx
- Hostname=xx

执行以下命令，启动/重启zabbix-agent：
sudo service zabbix-agent restart sudo service zabbix-agent status 执行一下命令，设置开机启动zabbix-agent：
sudo update-rc.d zabbix-agent enable 2-6、在云主机的防火墙开通TCP下行端口10050
青云控制台，在云主机的防火墙开通TCP下行端口10050。
2-7、在zabbix-server的web 控制台添加该云主机
选择被动监控方式、Linux监控模板、输入上述配置的Hostname、云主机的IP地址、zabbix-agent的端口10050。
完成上述步骤后，就可以在zabbix-server web console看到该云主机的监控数据了。
