1 准备工作
安装好Linux操作系统这里选择的是Linux 7:
[root@slave1 software]# cat /etc/redhat-release CentOS Linux release 7.6.1810 (Core)
关闭防火墙 和 Selinux:
[root@slave1 software]# systemctl stop firewalld [root@slave1 software]# systemctl disable firewalld [root@slave1 software]# vi /etc/selinux/config [root@slave1 software]# cat /etc/selinux/config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of three values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. Only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted
创建DM用户:
[root@slave1 software]# groupadd dinstall [root@slave1 software]# useradd -g dinstall -m -d /home/dmdba -s /bin/bash dmdba [root@slave1 software]# passwd dmdba Changing password for user dmdba. New password: BAD PASSWORD: The password is shorter than 8 characters Retype new password: passwd: all authentication tokens updated successfully. [root@slave1 software]#
创建目录:存储dm数据库文件的空间需要提前规划并挂载好,我这里放在/dm目录下:
[root@slave1 software]# mkdir -p /dm/dmdbms [root@slave1 software]# mkdir -p /dm/dmarch [root@slave1 software]# mkdir -p /dm/dmbak [root@slave1 software]# chown -R dmdba:dinstall /dm/ [root@slave1 software]# chmod -R 775 /dm/
配置系统限制,在/etc/security/limits.conf 文件中添加如下内容:
[root@slave1 software]# vim /etc/security/limits.conf dmdba soft nofile 65536 dmdba hard nofile 65536
配置环境变量:在dmdba用户的~/.bash_profile 里添加如下内容:
export DM_HOME="/dm/dmdbms" export LD_LIBRARY_PATH="/dm/dmdbms/bin:$LD_LIBRARY_PATH" export PATH="/dm/dmdbms/bin:$PATH"
注意,在DM 软件安装时会自动添加DM_HOME 和 LD_LIBRARY_PATH 变量,这里只需要添加PATH即可。
2 安装DM 数据库
复制安装文件: 将DM的ISO上传到Linux系统,并挂载:
[root@slave1 software]# mount dm7开发版(rh7-64)20190917.iso /mnt/ mount: /dev/loop0 is write-protected, mounting read-only [root@slave1 software]# cd /mnt/ [root@slave1 mnt]# ls DMInstall.bin DM_Install_en.pdf DM_Install_zh.pdf release_en.txt release_zh.txt
将安装文件复制到/dm 目录下并修改安装文件权限:
[root@slave1 mnt]# pwd /mnt [root@slave1 mnt]# cp ./DMInstall.bin /dm/ [root@slave1 mnt]# cd /dm [root@slave1 dm]# ll total 573076 drwxrwxr-x 2 dmdba dinstall 6 Dec 9 23:08 dmarch drwxrwxr-x 2 dmdba dinstall 6 Dec 9 23:08 dmbak drwxrwxr-x 2 dmdba dinstall 6 Dec 9 23:08 dmdbms -r-xr-xr-x 1 root root 586828259 Dec 9 23:14 DMInstall.bin [root@slave1 dm]# chown dmdba:dinstall DMInstall.bin [root@slave1 dm]# ll total 573076 drwxrwxr-x 2 dmdba dinstall 6 Dec 9 23:08 dmarch drwxrwxr-x 2 dmdba dinstall 6 Dec 9 23:08 dmbak drwxrwxr-x 2 dmdba dinstall 6 Dec 9 23:08 dmdbms -r-xr-xr-x 1 dmdba dinstall 586828259 Dec 9 23:14 DMInstall.bin
用dmdba用户执行./DMInstall.bin -i 程序,开始安装:
[root@slave1 dm]$ pwd /dm [root@slave1 dm]$ ./DMInstall.bin -i Please select the installer's language (E/e:English C/c:Chinese) [E/e]:c
解压安装程序.........
core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 3756 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 3756 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited
可打开文件数过少,建议至少设置为65536或更多。
欢迎使用达梦数据库安装程序
是否输入Key文件路径"color: #ff0000">3 创建数据库实例
[root@slave1 bin]$ pwd /dm/dmdbms/bin [root@slave1 bin]$ ./dminit PATH=/dm/dmdbms/data DB_NAME=dmdba INSTANCE_NAME=DMDBA CTL_PATH=/dm/dmdbms/data/dmdba/dm.ctl CASE_SENSITIVE=N CHARSET=1 initdb V7.6.0.197-Build(2019.09.12-112648)ENT db version: 0x7000a file dm.key not found, use default license! License will expire on 2020-09-12 log file path: /dm/dmdbms/data/dmdba/dmdba01.log log file path: /dm/dmdbms/data/dmdba/dmdba02.log write to dir [/dm/dmdbms/data/dmdba]. create dm database success. 2019-12-09 23:25:17
4 注册数据库服务
注册的shell 脚本dm_service_installer.sh在DM_HOME/script/root目录下,执行注册时需要使用root用户执行。
[root@slave1 bin]# cd /dm/dmdbms/script/root [root@slave1 root]# ./dm_service_installer.sh -t dmserver -i /dm/dmdbms/data/dmdba/dm.ini -p dmdba Created symlink from /etc/systemd/system/multi-user.target.wants/DmServicedmdba.service to /usr/lib/systemd/system/DmServicedmdba.service.
创建服务(DmServicedmdba)完成
5 启动数据库
[root@slave1 root]# systemctl enable DmServicedmdba.service [root@slave1 root]# systemctl start DmServicedmdba
6 客户端连接
出现如下画面,说明安装成功,可以正常使用了。
