 zabbix-agent安装

sed -i 's/=enforcing/=disabled/g' /etc/selinux/config
systemctl stop firewalld
systemctl disable firewalld
useradd -u 1001 -M -s /sbin/nologin zabbix
rpm -ivh http://mirrors.aliyun.com/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-agent-4.0.2-1.el7.x86_64.rpm
sed -i 's/127.0.0.1/10.0.0.70/g' /etc/zabbix/zabbix_agentd.conf
sed -i 's/# ListenPort=10050/ListenPort=10050/g' /etc/zabbix/zabbix_agentd.conf
systemctl start zabbix-agent.service
systemctl enable zabbix-agent.service

自定义监控业务

如果监控一些自定的监控比如请求数量，未超时的数量，并发数量，使用netstat命令报错的话需要授权用户有s 粘滞位权限（chmod au+s /usr/bin/netstat）

tail -3 /etc/zabbix/zabbix_agentd.conf

Grafana安装及配置

wget https://dl.grafana.com/oss/release/grafana-6.7.1-1.x86_64.rpm
yum install -y grafana-6.7.1-1.x86_64.rpm
systemctl enable grafana-server.service
systemctl start grafana-server.service

获取插件

grafana-cli plugins list-remote

安装zabbix插件

grafana-cli plugins install alexanderzobnin-zabbix-app
systemctl restart grafana-server.service
