logstash安装教程

以下是在 Ubuntu 系统上安装 Logstash 的步骤：

1. 安装 Java：Logstash 是基于 Java 开发的，因此需要先安装 Java。在终端输入以下命令：

   sudo apt install openjdk-8-jdk

2. 导入 Logstash GPG 密钥：

   wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -

3. 添加 Logstash 软件包源：

   echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list

4. 更新软件包列表：

   sudo apt update

5. 安装 Logstash：

   sudo apt install logstash

6. 启动 Logstash：

   sudo systemctl start logstash

7. 验证 Logstash 是否在运行：

   sudo systemctl status logstash

如果 Logstash 启动成功，你应该能够看到类似于以下的输出：
