Prometheus 是一个功能丰富的监控系统，具有广泛的优势，例如实时数据收集、警报功能和用户友好的基于 Web 的仪表板。
在 Manjaro 上安装 Prometheus
步骤 1。在深入研究 Prometheus 安装之前，确保您的 Manjaro 系统是最新的至关重要。打开终端并执行以下命令：
<span class="pln">sudo pacman </span><span class="pun">-</span><span class="typ">Syu</span><span class="pln"> sudo pacman </span><span class="pun">-</span><span class="pln">S git </span><span class="kwd">base</span><span class="pun">-</span><span class="pln">devel</span>
第2步。在 Manjaro 上安装 Prometheus。
要安装 Prometheus，我们将下载 Prometheus 二进制文件，为 Prometheus 创建专用用户和组，设置配置，并将 Prometheus 作为服务运行。systemd
- 方法 1：手动下载和安装二进制文件。
现在访问 Prometheus 下载页面并获取最新版本的 URL。在撰写本文时，最新版本为 2.47.2，但您应该使用可用的最新版本。
<span class="pln">wget https</span><span class="pun">:</span><span class="com">//github.com/prometheus/prometheus/releases/download/v2.47.2/prometheus-2.47.2.linux-amd64.tar.gz</span>
运行以下命令，将 prometheus 二进制文件移动到 /usr/local/bin：
<span class="pln">sudo mv prometheus</span><span class="pun">-</span><span class="lit">2.47</span><span class="pun">.</span><span class="lit">2.linux</span><span class="pun">-</span><span class="pln">amd64</span><span class="pun">/</span><span class="pln">prometheus </span><span class="pun">/</span><span class="pln">usr</span><span class="pun">/</span><span class="kwd">local</span><span class="pun">/</span><span class="pln">bin</span><span class="pun">/</span>
通过运行以下命令为 Prometheus 创建新用户：
<span class="pln">sudo useradd </span><span class="pun">--</span><span class="kwd">no</span><span class="pun">-</span><span class="pln">create</span><span class="pun">-</span><span class="pln">home </span><span class="pun">--</span><span class="pln">shell </span><span class="pun">/</span><span class="pln">bin</span><span class="pun">/</span><span class="kwd">false</span><span class="pln"> prometheus</span>
通过运行以下命令为 Prometheus 数据创建一个新目录：
<span class="pln">sudo mkdir </span><span class="pun">/</span><span class="kwd">var</span><span class="pun">/</span><span class="pln">lib</span><span class="pun">/</span><span class="pln">prometheus</span>
通过运行以下命令，将 /var/lib/prometheus 目录的所有权更改为 prometheus 用户：
<span class="pln">sudo chown prometheus</span><span class="pun">:</span><span class="pln">prometheus </span><span class="pun">/</span><span class="kwd">var</span><span class="pun">/</span><span class="pln">lib</span><span class="pun">/</span><span class="pln">prometheus</span>
通过运行以下命令为 Prometheus 配置文件创建一个新目录：
<span class="pln">sudo mkdir </span><span class="pun">/</span><span class="pln">etc</span><span class="pun">/</span><span class="pln">prometheus</span>
移动普罗米修斯。YML公司配置文件复制到 /etc/prometheus 目录下，执行以下命令：
<span class="pln">sudo mv prometheus</span><span class="pun">-</span><span class="lit">2.47</span><span class="pun">.</span><span class="lit">2.linux</span><span class="pun">-</span><span class="pln">amd64</span><span class="pun">/</span><span class="pln">prometheus</span><span class="pun">.</span><span class="pln">yml </span><span class="pun">/</span><span class="pln">etc</span><span class="pun">/</span><span class="pln">prometheus</span><span class="pun">/</span>
通过运行以下命令，将 /etc/prometheus 目录的所有权更改为 prometheus 用户：
<span class="pln">sudo chown prometheus</span><span class="pun">:</span><span class="pln">prometheus </span><span class="pun">/</span><span class="pln">etc</span><span class="pun">/</span><span class="pln">prometheus</span>
通过运行以下命令为 Prometheus 创建新的 systemd 服务文件：
<span class="pln">sudo nano </span><span class="pun">/</span><span class="pln">etc</span><span class="pun">/</span><span class="pln">systemd</span><span class="pun">/</span><span class="pln">system</span><span class="pun">/</span><span class="pln">prometheus</span><span class="pun">.</span><span class="pln">service</span>
将以下内容粘贴到文件中：
<span class="pun">[</span><span class="typ">Unit</span><span class="pun">]</span>
<span class="typ">Description</span><span class="pun">=</span><span class="typ">Prometheus</span>

保存并关闭文件，然后通过运行以下命令来关闭 Prometheus 服务：
<span class="pln">sudo systemctl daemon</span><span class="pun">-</span><span class="pln">reload sudo systemctl start prometheus</span>
- 方法 2：使用包管理器。
通过运行以下命令安装 Prometheus：
<span class="pln">sudo pacman </span><span class="pun">-</span><span class="pln">S prometheus</span>
通过运行以下命令验证 Prometheus 是否已安装：
<span class="pln">prometheus </span><span class="pun">--</span><span class="pln">version</span>
安装 Prometheus 后，启动 Prometheus 服务并使其在系统重启时启动：
<span class="pln">sudo systemctl start prometheus sudo systemctl start prometheus</span>
第 3 步。防火墙配置。
如果启用了防火墙，请确保允许端口 9090（Prometheus 的默认端口）上的传入流量：
<span class="pln">sudo ufw allow </span><span class="lit">9090</span><span class="pun">/</span><span class="pln">tcp</span>
第 4 步。访问 Prometheus Web UI。
现在，您可以从本地网络上的 Web 浏览器访问 Prometheus Web UI，方法是输入服务器的 IP 地址，然后输入端口 9090：
<span class="pln">http</span><span class="pun">:</span><span class="com">//your_server_ip:9090</span>
