Configure firewall

Netdata runs on port 19999, so you need to allow port 19999 through the UFW firewall. By default, UFW is not installed in Debian 9. You can install it by running the following command:

sudo apt-get install ufw -y 

Once UFW is installed, enable it using the following command:

sudo ufw enable 

Next, allow the use of UFW firewall port 19999 as follows:

sudo ufw allow 19999/tcp 

Next, reload the firewall to apply all changes:

sudo ufw reload 

Once the UFW firewall is configured, you can continue to access the Netdata web interface.

Access Netdata Web Interface

打开您的网络浏览器并输入URL http：// your-server-ip：19999 ，您将被重定向到Netdata仪表板，如下图所示：

您也可以通过输入URL http：// your-server-ip：19999 / netdata.conf在浏览器中查看Netdata的当前配置。 您应该看到以下页面：

在上图中，您应该看到所有可配置选项都被注释掉了。 您可以通过编辑/etc/netdata/netdata.conf文件来根据需要对其进行配置。

更新和卸载Netdata

如果您想从系统中删除Netdata，则可以运行以下命令：

cd netdata  
sudo /netdata-uninstaller.sh --force 

如果要通过运行以下命令将Netdata更新为最新版本：

cd netdata  
git pull  
sudo ./netdata-installer.sh

恭喜！ 您已经在Debian 9上成功安装Netdata。
