docker部署grafana并展示zabbix监控
为的是更绚丽的界面，grafana仅仅是展示用，不会修改zabbix数据
grafana需要连接 zabbix server和mysql数据库
条件有限，就用tomcat这个机器做grafana,下面仅仅是测试用
一、安装docker
[root@tomcat1 ~]# curl -sSL https://gitee.com/uscwifi/scripts/raw/master/docker_ubuntu_install.sh | bash
#修改docker的service文件，打开FORWARD
[root@tomcat1 ~]# vim /lib/systemd/system/docker.service
[root@tomcat1 ~]# systemctl daemon-reload
[root@tomcat1 ~]# systemctl daemon-reload
[root@tomcat1 ~]# systemctl restart docker
[root@tomcat1 ~]# iptables -vnL FORWARD
Chain FORWARD (policy DROP 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
0 0 ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0
二、部署grafana
[root@tomcat1 ~]# docker run -d --name=grafana -p 3000:3000 grafana/grafana
三、安装zabbix插件
参考：https://grafana.com/grafana/plugins/alexanderzobnin-zabbix-app
[root@tomcat1 ~]# docker exec -it grafana grafana-cli plugins install alexanderzobnin-zabbix-app
installing alexanderzobnin-zabbix-app @ 3.10.4
from: https://grafana.com/api/plugins/alexanderzobnin-zabbix-app/versions/3.10.4/download
into: /var/lib/grafana/plugins
✔ Installed alexanderzobnin-zabbix-app successfully
Restart grafana after installing plugins . <service grafana-server restart>
[root@tomcat1 ~]# docker restart grafana
四、启用zabbix插件
http://192.168.38.162:3000/login
默认用户名密码：admin/admin
左边小齿轮-> plugins ->zabbix图标 -> enable
五、添加mysql数据源
左边小齿轮-> data sources ->add data sources ->mysql图标
数据库没授权
mysql> grant all on zabbix.* to 'zabbix'@'192.168.38.%' identified by '123456';
六、添加zabbix数据源
左边小齿轮->Data Sources -> Add data source -> Others ->zabbix
url填：http://192.168.38.162:81/api_jsonrpc.php 根据自己的情况填
七、添加dashboard
可以自己添加dashboard，我这里直接导入别人的模版了，7877模版不错
