1 準備工作
安裝好Linux操作系統，這裏選擇的是Linux 7：
關閉防火牆 和 Selinux：
systemctl status firewalld
systemctl stop firewalld
systemctl disable firewalld
sed -i 's/=enforcing/=disabled/g' /etc/selinux/config
setenforce 0
getenforce
修改/etc/hosts 文件：
[root@dm1 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.31.166 dm1
[root@dm1 ~]#
hostnamectl set-hostname
創建DM用戶：
groupadd dinstall
useradd -g dinstall -m -d /home/dmdba -s /bin/bash dmdba
passwd dmdba
創建目錄：存儲dm數據庫文件的空間需要提前規劃並掛載好，我這裏放在/dm目錄下：
mkdir -p /dm/dmdbms
mkdir -p /dm/dmarch
mkdir -p /dm/dmbak
chown -R dmdba:dinstall /dm/
chmod -R 775 /dm/
配置系統限制，在/etc/security/limits.conf 文件中添加如下內容：
cat >> /etc/security/limits.conf << EOF
dmdba soft nofile 4096
dmdba hard nofile 65536
EOF
ulimit -a
配置環境變量：在dmdba用戶的~/.bash_profile 裏添加如下內容：
cat >>/home/dmdba/.bash_profile<<EOF
export DM_HOME="/dm/dmdbms"
export LD_LIBRARY_PATH="/dm/dmdbms/bin:\$LD_LIBRARY_PATH"
export PATH="/dm/dmdbms/bin:\$PATH"
export LD_LIBRARY_PATH="\$LD_LIBRARY_PATH:/dm/dmdbms/bin"
export DM_HOME="/dm/dmdbms"
EOF
2 安裝DM 數據庫
複製安裝文件: 將DM的ISO上傳到Linux系統，並掛載：
mount -t auto /dev/cdrom /mnt
[root@dm1 dm]# mount -o loop dm8_setup_rh7_64_ent_8.1.1.45_20191121.iso /mnt
mount: /dev/loop0 is write-protected, mounting read-only
將安裝文件複製到/dm 目錄下並修改安裝文件權限：
[root@dm1 mnt]# cp DMInstall.bin /dm/.
[root@dm1 dm]# chown -R dmdba:dinstall /dm
