logstash安装

1、下载并安装公共签名密钥

rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch

 2、创建镜像源文件：/etc/yum.repos.d/logstash.repo

[logstash-6.x]
name=Elastic repository for 6.x packages
baseurl=https://artifacts.elastic.co/packages/6.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

3、下载安装logstash：

sudo yum install logstash

4、创建logstash的启动文件（有的话不需要这一步）：/etc/systemd/system/logstash.service

[Unit]
Description=logstash

[Service]
Type=simple
User=logstash
Group=logstash
# Load env vars from /etc/default/ and /etc/sysconfig/ if they exist.
# Prefixing the path with '-' makes it try to load, but if the file doesn't
# exist, it continues onward.
EnvironmentFile=-/etc/default/logstash
EnvironmentFile=-/etc/sysconfig/logstash
ExecStart=/usr/share/logstash/bin/logstash "--path.settings" "/etc/logstash" -f /etc/logstash/conf.d
Restart=always
WorkingDirectory=/

[Install]

5、启动logstash（没有装java的话得装java）：

systemctl start logstash
