3.3 启动grafana

[root@dbc-server-554 grafana]# systemctl start grafana-server.service
[root@dbc-server-554 grafana]# systemctl enable grafana-server.service
Created symlink from /etc/systemd/system/multi-user.target.wants/grafana-server.service to /usr/lib/systemd/system/grafana-server.service.
[root@dbc-server-554 grafana]# systemctl status grafana-server.service
● grafana-server.service - Grafana instance
   Loaded: loaded (/usr/lib/systemd/system/grafana-server.service; enabled; vendor preset: disabled)

...
[root@dbc-server-554 grafana]# ss -nltp|grep grafana

可以看到grafana的对外端口号为3000

3.4 登录控制台

访问http://192.168.5.54:3000

如果无法登录，如下

解决方法：1.重启下grafana服务，2.换个浏览器，例如，使用chrome登录

登录账号及密码均是admin，按照提示修改密码，然后我们就进入了控制台

3.5 链接zabbix

Configuration -> data source ->Add data source

1.安装zabbix插件

默认没有安装zabbix插件，所以我们需要安装zabbix的数据源插件

安装方式：https://grafana.com/grafana/plugins/alexanderzobnin-zabbix-app/?tab=installation

1.Install the Application
Use the grafana-cli tool to install Zabbix from the commandline:

grafana-cli plugins install alexanderzobnin-zabbix-app
The plugin will be installed into your grafana plugins directory; the default is /var/lib/grafana/plugins. More information on the cli tool.

Alternatively, you can manually download the .zip file and unpack it into your grafana plugins directory.

[root@dbc-server-554 grafana]# grafana-cli plugins install alexanderzobnin-zabbix-app
✔ Downloaded and extracted alexanderzobnin-zabbix-app v4.2.10 zip successfully to /var/lib/grafana/plugins/alexanderzobnin-zabbix-app

Please restart Grafana after installing plugins. Refer to Grafana documentation for instructions if necessary.
[root@dbc-server-554 grafana]# systemctl restart grafana-server.service
