CentOS下安装FileBeat主要有以下步骤：
sudo yum update -y命令更新系统包。wget https://artifacts.elastic.co/GPG-KEY-elasticsearch，然后创建仓库配置文件目录sudo mkdir -p /etc/yum.repos.d/elastic-7.x，接着下载并安装仓库配置文件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/，最后导入密钥sudo rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch。sudo yum install filebeat -y进行安装。sudo systemctl start filebeat启动服务，用sudo systemctl enable filebeat设置开机自启动。sudo systemctl status filebeat查看服务状态，若显示“active (running)”，则安装成功。
