一键安装脚本实现快速部署GrayLog Server 4.2.10单机版

一键安装脚本实现快速部署GrayLog Server 4.2.10单机版

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

(图片可点击放大查看)

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

脚本内容如下

Tips

若需要修改admin登录密码请使用如下命令

echo -n "Enter Password: " && head -1 </dev/stdin | tr -d '\n' | sha256sum | cut -d" " -f1
并修改/etc/graylog/server/server.conf 中root_password_sha2值
重启Graylog服务生效
