CentOS下安裝FileBeat主要有以下步驟：
sudo yum update -y命令更新系統包。wget https://artifacts.elastic.co/GPG-KEY-elasticsearch，然后創建倉庫配置文件目錄sudo mkdir -p /etc/yum.repos.d/elastic-7.x，接著下載并安裝倉庫配置文件sudo wget https://artifacts.elastic.co/packages/7.x/yum/elastic-release-7.x-4.noarch.rpm -P /etc/yum.repos.d/elastic-7.x/，最后導入密鑰sudo rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch。sudo yum install filebeat -y進行安裝。sudo systemctl start filebeat啟動服務，用sudo systemctl enable filebeat設置開機自啟動。sudo systemctl status filebeat查看服務狀態，若顯示“active (running)”，則安裝成功。
