如何在Ubuntu 18.04 LTS上安装Grafana Monitoring Tool

Grafana是一个免费的开源企业级监控和数据可视化工具，支持Graphite，InfluxDB，Prometheus，Elasticsearch和更多数据库。您可以为自己的应用程序或基础架构性能监控创建自己的仪表板。

在本教程中，我们将解释如何在Ubuntu 18.04 LTS（Bionic Beaver）上安装Grafana。

先决条件

运行Ubuntu 16.04的服务器。
具有sudo权限的N非root用户。

安装Grafana

默认情况下，Grafana在Ubuntu 18.04默认存储库中不可用。因此，您需要将Grafana存储库添加到您的系统中。您可以使用以下命令添加它：

sudo nano /etc/apt/sources.list

在文件末尾添加以下行：

deb https://packagecloud.io/grafana/stable/debian/ stretch main

保存并关闭该文件，然后使用以下命令添加GPG密钥：

sudo curl https://packagecloud.io/gpg.key | sudo apt-key add -

接下来，使用以下命令更新Grafana存储库并安装Grafana：

sudo apt-get update -y
sudo apt-get install grafana -y

安装成功完成后，您应该看到以下输出：

Preparing to unpack .../grafana_5.1.3_amd64.deb ...

### NOT starting on installation, please execute the following statements to configure grafana to start automatically using systemd
 sudo /bin/systemctl daemon-reload
 sudo /bin/systemctl enable grafana-server
### You can start grafana-server by executing
 sudo /bin/systemctl start grafana-server
Processing triggers for ureadahead (0.100.0-20) ...
Processing triggers for systemd (237-3ubuntu10) ...

接下来，启动Grafana服务器并使用以下命令使其在启动时启动：

sudo systemctl daemon-reload
sudo systemctl enable grafana-server
sudo systemctl start grafana-server

接下来，使用以下命令检查Grafana服务器的状态：

sudo systemctl status grafana-server

输出：
