一、安装前环境准备
1.创建用户
groupadd dinstall
useradd -g dinstall -m -d /home/dmdba -s /bin/bash dmdba
id dmdba
uid=1000(dmdba) gid=1000(dinstall) 组=1000(dinstall)
2.操作系统资源限制检查
ulimit -SHn 65535
vim /etc/security/limits.conf
* soft nofile 65535
* hard nofile 65535
* soft nproc 65535
* hard nproc 65535
vim /etc/sysctl.conf
fs.file-max=655360
net.ipv4.ip_forward = 1
net.ipv6.conf.all.disable_ipv6 =1
sysctl -p
关闭防火墙
systemctl stop firewalld && systemctl disable firewalld
3.上传安装包解压挂载
unzip dm8_20240116_x86_rh7_64.zip
yum install -y unzip
unzip dm8_20240116_x86_rh7_64.zip
mount dm8_20240116_x86_rh7_64.iso /mnt/
4.切换到dmdba配置环境变量
su - dmdba
vim .bash_profile
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/data/dmdbms/bin"
export DM_HOME="/data/dmdbms"
source .bash_profile
二、安装达梦数据库
1.创建安装目录
mkdir -p /data/dmdbms
2.安装
cd /mnt/
./DMInstall.bin -i
安装目录填写/data/dmdbms
切换到dmdba，初始化数据库
su - dmdba
cd /data/dmdbms/bin
./dminit PATH=/data/dmdbms/data page_size=32 case_sensitive=0 CHARSET=1 EXTENT_SIZE=32 LENGTH_IN_CHAR=1
配置开机启动
/data/dmdbms/script/root/dm_service_installer.sh -t dmserver -p DMSERVER -dm_ini /data/dmdbms/data/DAMENG/dm.ini
systemctl status DmServiceDMSERVER
systemctl enable DmServiceDMSERVER
systemctl start DmServiceDMSERVER
netstat -ntpl|grep 5236
