一键安装脚本实现快速部署GrayLog Server 4.2.10单机版

一、需求背景

由于局点（分支机构）较多，为了快速部署GrayLog单机版

所以简单整理了一下GrayLog的安装步骤脚本，来实现一键安装GrayLog Server 4.2.10单机版

只需上传GraylogServer4.2.10_install.tar.gz和GrayLogServer_install.sh安装脚本并执行一键安装脚本即可完成GrayLog Server 4.2.10单机版的安装

说明： - 1、GraylogServer4.2.10_install.tar.gz中为GrayLogServer安装时所需的JDK+pwgen+MongoDB+elasticsearch+graylog-server的RPM包 使用createrepo方式打包制作成本地yum源来实现离线yum安装  - 2、建议的资源配置如下 操作系统：CentOS7.9 CPU 8核 内存建议8GB内存以上 磁盘大小:建议单独一块数据盘，并挂载到/data目录 - 3、其中ES和MongoDB未做加密认证，因为只监听在本地127.0.0.1不对外暴露，若需要安全加固，请自行配置 GrayLogServer_install.sh脚本 ## 二、一键安装脚本内容如下
