我们将向您展示如何在 Fedora 37 上安装 Graylog。您是否正在努力管理和分析 Fedora 37 系统上各种来源的日志？如果是这样，Graylog可能是您一直在寻找的解决方案。Graylog 是一个开源日志管理系统，可以收集、索引和分析来自不同来源的大量日志数据。它提供了一个用于搜索、分析和可视化日志数据的集中式平台，使其成为任何系统管理员的必备工具。
在 Fedora 37 上安装 Graylog
第 1 步。在继续之前，请更新您的 Fedora 操作系统以确保所有现有软件包都是最新的。使用此命令更新服务器软件包：
<span class="pln">sudo dnf upgrade sudo dnf update</span>
第 2 步。安装爪哇。
Elasticsearch 依赖于 Java，在 Fedora 上安装 Elasticsearch 之前，您需要在机器上安装它。运行以下命令以安装 OpenJDK 包：
<span class="pln">sudo dnf install java</span><span class="pun">-</span><span class="lit">11</span><span class="pun">-</span><span class="pln">openjdk</span>
使用以下命令验证 Java 版本：
<span class="pln">java </span><span class="pun">-</span><span class="pln">version</span>
第 3 步。安装 Elasticsearch。
默认情况下，Elasticsearch 在 Fedora 37 基础存储库中不可用。现在我们将 Elasticsearch RPM 存储库添加到您的 Fedora 系统中：
<span class="pln">sudo rpm </span><span class="pun">--</span><span class="kwd">import</span><span class="pln"> https</span><span class="pun">:</span><span class="com">//artifacts.elastic.co/GPG-KEY-elasticsearch</span><span class="pln"> echo </span><span class="str">"[elasticsearch-7.10.2] name=Elasticsearch repository for 7.10.2 packages baseurl=https://artifacts.elastic.co/packages/oss-7.x/yum gpgcheck=1 gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch enabled=1 autorefresh=1 type=rpm-md"</span> <span class="pun">|</span><span class="pln"> sudo tee </span><span class="pun">/</span><span class="pln">etc</span><span class="pun">/</span><span class="pln">yum</span><span class="pun">.</span><span class="pln">repos</span><span class="pun">.</span><span class="pln">d</span><span class="pun">/</span><span class="pln">elasticsearch</span><span class="pun">.</span><span class="pln">repo</span>
接下来，导入 Elasticsearch GPG 密钥：
<span class="pln">rpm </span><span class="pun">--</span><span class="kwd">import</span><span class="pln"> https</span><span class="pun">:</span><span class="com">//artifacts.elastic.co/GPG-KEY-elasticsearch</span>
完成后，在 Fedora 系统上安装 Elasticsearch 软件包：
<span class="pln">sudo dnf update sudo yum install elasticsearch</span><span class="pun">-</span><span class="pln">oss</span>
安装完成后，现在启用 Elasticsearch（在系统启动时自动启动）、启动并使用以下命令验证状态：
<span class="pln">sudo systemctl start elasticsearch sudo systemctl enable elasticsearch sudo systemctl status elasticsearch</span>
第 4 步。安装 MongoDB。
现在我们运行以下命令在 Fedora 系统上添加 MongoDB 仓库：
<span class="pln">nano </span><span class="pun">/</span><span class="pln">etc</span><span class="pun">/</span><span class="pln">yum</span><span class="pun">.</span><span class="pln">repos</span><span class="pun">.</span><span class="pln">d</span><span class="pun">/</span><span class="pln">mongodb</span><span class="pun">-</span><span class="pln">org</span><span class="pun">.</span><span class="pln">repo</span>
添加以下文件：
<span class="pun">[</span><span class="pln">mongodb</span><span class="pun">-</span><span class="pln">org</span><span class="pun">-</span><span class="lit">6.0</span><span class="pun">]</span><span class="pln"> name</span><span class="pun">=</span><span class="typ">MongoDB</span> <span class="typ">Repository</span><span class="pln"> baseurl</span><span class="pun">=</span><span class="pln">https</span><span class="pun">:</span><span class="com">//repo.mongodb.org/yum/redhat/$releasever/mongodb-org/6.0/x86_64/</span><span class="pln"> gpgcheck</span><span class="pun">=</span><span class="lit">1</span><span class="pln"> enabled</span><span class="pun">=</span><span class="lit">1</span><span class="pln"> gpgkey</span><span class="pun">=</span><span class="pln">https</span><span class="pun">:</span><span class="com">//www.mongodb.org/static/pgp/server-6.0.asc</span>
之后，使用以下命令更新软件包并安装MongoDB的最新稳定版本：
<span class="pln">sudo dnf update sudo yum install mongodb</span><span class="pun">-</span><span class="pln">org</span>
安装完成后，我们需要启动MongoDB服务器才能开始运行。我们使用以下命令执行此操作：
<span class="pln">sudo systemctl start mongod sudo systemctl enable mongod</span>
第5步。在 Fedora 37 上安装 RustDesk。
默认情况下，RustDesk 在 Fedora 37 默认存储库中不可用。现在打开系统上的终端并运行以下命令将 Graylog 存储库添加到您的系统中：
<span class="pln">sudo rpm </span><span class="pun">-</span><span class="typ">Uvh</span><span class="pln"> https</span><span class="pun">:</span><span class="com">//packages.graylog2.org/repo/packages/graylog-5.0-repository_latest.rpm</span>
添加存储库后，运行以下命令以在系统上安装 Graylog：
<span class="pln">sudo dnf install graylog</span><span class="pun">-</span><span class="pln">server</span>
安装完成后，使用以下命令启动 Graylog 服务：
<span class="pln">sudo systemctl start graylog</span><span class="pun">-</span><span class="pln">server sudo systemctl enable graylog</span><span class="pun">-</span><span class="pln">server</span>
第 6 步。灰日志的配置。
在 Fedora 37 上安装 Graylog 后，我们需要配置它以开始处理日志。使用以下命令打开位于 的 Graylog 配置文件：/etc/graylog/server/server.conf
<span class="pln">nano </span><span class="pun">/</span><span class="pln">etc</span><span class="pun">/</span><span class="pln">graylog</span><span class="pun">/</span><span class="pln">server</span><span class="pun">/</span><span class="pln">server</span><span class="pun">.</span><span class="pln">conf</span>
在配置文件中找到以下行并设置系统的 IP 地址：
<span class="pln">rest_listen_uri </span><span class="pun">=</span><span class="pln"> http</span><span class="pun">:</span><span class="com">//127.0.0.1:9000/api/</span>
将其更改为：
<span class="pln">rest_listen_uri </span><span class="pun">=</span><span class="pln"> http</span><span class="pun">:</span><span class="com">//<your-IP-address>:9000/api/</span>
在配置文件中找到以下行并取消注释：
<span class="com">#web_listen_uri = http://127.0.0.1:9000/</span>
将其更改为：
<span class="pln">web_listen_uri </span><span class="pun">=</span><span class="pln"> http</span><span class="pun">:</span><span class="com">//<your-IP-address>:9000/api/</span>
此外，添加 password_secret 和 root_password sha2，因为这些是强制性的，没有它们，Graylog 将无法启动。要创建 ，请运行以下命令：root_password_sha2
<span class="pln">echo </span><span class="pun">-</span><span class="pln">n </span><span class="str">"Enter Password: "</span> <span class="pun">&&</span><span class="pln"> head </span><span class="pun">-</span><span class="lit">1</span> <span class="pun"><</span><span class="str">/dev/</span><span class="pln">stdin </span><span class="pun">|</span><span class="pln"> tr </span><span class="pun">-</span><span class="pln">d </span><span class="str">'\n'</span> <span class="pun">|</span><span class="pln"> sha256sum </span><span class="pun">|</span><span class="pln"> cut </span><span class="pun">-</span><span class="pln">d</span><span class="str">" "</span> <span class="pun">-</span><span class="pln">f1</span>
接下来，生成一个：password_secret
<span class="pln">< /dev/urandom tr -dc A-Z-a-z-0-9 | head -c${1:-96};echo;</span>
最后，使用以下命令重新启动 Graylog 服务：
<span class="pln">sudo systemctl restart graylog</span><span class="pun">-</span><span class="pln">server</span>
步骤 7.配置防火墙。
我们需要将防火墙配置为允许 Graylog 服务器的流量通过端口 9000：
<span class="pln">sudo firewall</span><span class="pun">-</span><span class="pln">cmd </span><span class="pun">--</span><span class="kwd">add</span><span class="pun">-</span><span class="pln">port</span><span class="pun">=</span><span class="lit">9000</span><span class="pun">/</span><span class="pln">tcp </span><span class="pun">--</span><span class="pln">permanent sudo firewall</span><span class="pun">-</span><span class="pln">cmd </span><span class="pun">--</span><span class="pln">reload</span>
第8步。访问格雷日志网页界面。
成功安装后，打开您的网络浏览器并使用 URL 访问 WordPress CMS .您将被重定向到以下页面：http://your-IP-address:9000
