基础环境说明

• 1、CentOS7.9（关闭SELINUX）
• 2、GrayLog5.1.10一键安装脚本和相关组件压缩包

MongoDB6.0+OpenSearch2.8+GrayLog5.1.10的EL7版本rpm安装包

• 3、环境说明 建议内存大于8G，CPU8核及以上

建议专门一个/data分区,(LVM可扩展更佳),用于存放用GrayLog采集的日志

一键脚本安装过程如下

1、SFTP上传如下文件

• GrayLog5.1.10_MongoDB6.0_opensearch2.8_RPM.tar.gz
• GrayLogServer5.1.10_install.sh

(图片点击放大查看)

然后执行shell脚本即可一键完成安装

2、安装完成后即可登录GrayLog Web界面

账号密码为admin/Graylog@2023
