centos7安装开源日志系统graylog5.1.2

安装包链接：链接：https://pan.baidu.com/s/1Zl5s7x1zMWpuKfaePy0gPg?pwd=1eup 
提取码：1eup

这里采用的shell脚本安装，脚本如下：

先使用命令产生2个参数代入到脚本中：

使用pwgen生成password_secret密码

pwgen -N 1 -s 96

使用如下命令生成root_password_sha2密码字符串（这个为登录密码）

echo -n "Enter Password: " && head -1 

将生成的password_secret密码和root_password_sha2密码字符串 添加到脚本中
