安装准备工作

Logstash所需的唯一主要前提条件是Java。
另外我们将使用“wget”直接下载Logstash Debian软件包：

# apt update 
# apt install openjdk-8-jdk-headless wget

下载logstash

$wget  --no-check-certificate https://artifacts.elastic.co/downloads/logstash/logstash-5.2.0.deb

启动logstash

启动LogStash并设置开机自启动：

# systemctl start logstash
# systemctl enable logstash

查看logstash的状态

#  systemctl status logstash
● logstash.service - logstash
   Loaded: loaded (/etc/systemd/system/logstash.service; enabled; vendor preset: enabled)
   Active: active (running) since Sun 2015-02-12 08:38:00 AEDT; 47s ago
 Main PID: 420 (java)
    Tasks: 14 (limit: 4915)

安装插件

Logstash将其可执行二进制文件保存在/usr/share/Logstash/bin/中。
设置可执行路径以包含Logstash的可执行路径：

# export PATH=$PATH:/usr/share/logstash/bin/

使用logstash-plugin安装插件：

# logstash-plugin install PLUGIN-NAME
