-------------------------环境初始化-------------------------
---图形化界面安装
（1）第一次启动虚拟机，执行下 xhost +
xhost +
access control disabled, clients can connect from any host
（2）查看 root 用户的 DISPLAY 变量值
echo $DISPLAY
:0.0
（3）切换 dmdba 用户
su - dmdba
export DISPLAY=:0.0

--创建数据库实例
运行 dbca.sh 创建数据库
cd /dm8/tool
./dbca.sh

--查看防火墙状态
systemctl status firewalld.service
--关防火墙
systemctl stop firewalld.service

--注册实例服务（图形化安装不用注册）
[root@~]# /data/dmdbms/script/root/dm_service_installer.sh -t dmserver -p DMSVR01 -dm_ini /data/dmdbms/data/JJDB/dm.ini -m mount

--停数据库服务

--停数据库服务
cd /dm8/bin

--创建备份目录
mkdir /dm8/backup
