一鍵安裝腳本實現快速部署GrayLog Server 4.2.10單機版

由于局點（分支機構）較多，為了快速部署GrayLog單機版

所以簡單整理了一下GrayLog的安裝步驟腳本，來實現一鍵安裝GrayLog Server 4.2.10單機版

只需上傳GraylogServer4.2.10_install.tar.gz和GrayLogServer_install.sh安裝腳本并執行一鍵安裝腳本即可完成GrayLog Server 4.2.10單機版的安裝

說明：

1、GraylogServer4.2.10_install.tar.gz中為GrayLogServer安裝時所需的JDK+pwgen+MongoDB+elasticsearch+graylog-server的RPM包使用createrepo方式打包制作成本地yum源來實現離線yum安裝

2、建議的資源配置如下 操作系統：CentOS7.9 CPU 8核 內存建議8GB內存以上 磁盤大小:建議單獨一塊數據盤，并掛載到/data目錄 3、其中ES和MongoDB未做加密認證，因為只監聽在本地127.0.0.1不對外暴露，若需要安全加固，請自行配置

安裝過程截圖如下

目前只在CentOS7.9環境下進行部署測試，其他版本未測試

Tips

若需要修改admin登錄密碼請使用如下命令

echo-n"EnterPassword:"&&head-1'
'|sha256sum|cut-d""-f1
并修改/etc/graylog/server/server.conf中root_password_sha2值
重啟Graylog服務生效
