二、中标麒麟操作系统环境配置

2.1 上传达梦数据库安装介质

sftp> cd /software

sftp> pwd

/software

sftp> put -r "D:\BaiduNetdiskDownload\dm8_setup_rh7_64_ent_8.1.1.88_20200629.iso"

sftp> put -r "D:\BaiduNetdiskDownload\dm8_setup_rh7_64_ent_8.1.1.88_20200629_ISO_SHA256.txt"

2.2 校验达梦数据库安装介质有效性

[root@localhost software]# sha256sum dm8_setup_rh7_64_ent_8.1.1.88_20200629.iso

9c3b14a82a809aea86334b49d8439b36ab558d4ee7e7a27dbda609a27352a64b  dm8_setup_rh7_64_ent_8.1.1.88_20200629.iso

[root@localhost software]# cat dm8_setup_rh7_64_ent_8.1.1.88_20200629_ISO_SHA256.txt

9c3b14a82a809aea86334b49d8439b36ab558d4ee7e7a27dbda609a27352a64b

2.3 安装版本管理工具

[root@bogon ~]# lsb_release -a

[root@bogon ~]# cat /etc/redhat-release

2.4 安装系统包

[root@bogon ~]# yum install compat-glibc*

[root@bogon ~]# rpm -qa|grep glibc

2.5 配置达梦数据库用户

[root@bogon ~]# groupadd dinstall

[root@bogon ~]# useradd -g dinstall dmdba

[root@bogon ~]# echo "dmdba123"|passwd --stdin dmdba

[root@bogon ~]# id dmdba

uid=1001(dmdba) gid=1002(dinstall) 组=1002(dinstall)

[root@bogon ~]# mkdir /opt/dm8

[root@bogon ~]# chown dmdba:dinstall /opt/dm8

[root@bogon ~]# ls -ld /opt/dm8

drwxr-xr-x 2 dmdba dinstall 6 11月 23 11:42 /opt/dm8

2.6 配置中标麒麟操作系统参数

[root@bogon ~]# cat >> /etc/security/limits.conf << EOF

> dmdba soft nofile 65536

> dmdba hard nofile 65536

> EOF

[root@bogon ~]# cat >> /etc/profile << EOF

> ulimit -n 65536

> EOF

ulimit -a

三、安装达梦数据库

3.1 安装数据库软件(图形界面安装，不建库)

[root@bogon software]# chown dmdba:dinstall dm8_setup_rh7_64_ent_8.1.1.88_20200629.iso

[root@bogon software]# ls -l

总用量 660228

-rw-r--r-- 1 dmdba dinstall 676069376 10月 31 17:54 dm8_setup_rh7_64_ent_8.1.1.88_20200629.iso

-rw-r--r-- 1 root  root            64 10月 31 17:54 dm8_setup_rh7_64_ent_8.1.1.88_20200629_ISO_SHA256.txt

[root@bogon software]# mount -o loop dm8_setup_rh7_64_ent_8.1.1.88_20200629.iso /mnt/

mount: /dev/loop0 写保护，将以只读方式挂载

[root@bogon mnt]# xhost +

[root@bogon mnt]# su – dmdba

[dmdba@bogon mnt]$export DISPLAY=127.0.0.1:0.0

[dmdba@bogon mnt]$cd /mnt

[dmdba@bogon mnt]$./DMInstall.bin

3.2 安装数据库软件(静默安装，不建库)

[dmdba@bogon mnt]$ ./DMInstall.bin -i

[dmdba@bogon mnt]$ /opt/dm8/script/root/root_installer.sh

3.3 创建数据库(图形界面安装)

su – dmdba

vi .bash_profile

export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/opt/dm8/bin"

export DM_HOME="/opt/dm8"

export PATH=$DM_HOME/bin:$DM_HOME/tool:$PATH

source .bash_profile

[root@bogon mnt]# xhost +

[root@bogon mnt]# su – dmdba

[dmdba@bogon mnt]$export DISPLAY=127.0.0.1:0.0

[dmdba@bogon mnt]dbca.sh

[root@bogon software]#mv /opt/dm8/bin/DMServiceDMSERVER.service /usr/lib/systemd/system/DmServiceDMSERVER.service

[root@bogon software]#systemctl enable DmServiceDMSERVER.service

[root@bogon software]#systemctl start DmServiceDMSERVER.service

[root@bogon software]#systemctl status DmServiceDMSERVER.service

[root@bogon software]#systemctl is-enabled DmServiceDMSERVER.service

[root@bogon software]#systemctl list-unit-files DmServiceDMSERVER.service

[dmdba@bogon mnt]$disql sysdba/damengdba123;

[dmdba@bogon mnt]$disql sysdba/damengdba123@127.0.0.1:5236

3.4 创建数据库(静默安装)

----创建数据库---

su – dmdba

vi .bash_profile

export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/opt/dm8/bin"

export DM_HOME="/opt/dm8"

export PATH=$DM_HOME/bin:$DM_HOME/tool:$PATH

source .bash_profile

[dmdba@bogon bin]$ ./dminit path='/opt/dm8/data/' page_size=16 extent_size=32 case_sensitive=Y db_name=PROED instance_name=ENMO port_num=5252 sysdba_pwd=EnmoEdu123 sysauditor_pwd=EnmoEdu123

---注册数据库服务---

[root@bogon ~]# cd /opt/dm8/script/root/

[root@bogon root]# ./dm_service_installer.sh -t dmserver -p PROED -dm_ini /opt/dm8/data/PROED/dm.ini

[root@bogon root]# systemctl start DmServicePROED

[root@bogon root]# systemctl status DmServicePROED

四、数据库后续配置任务

4.1 创建样例用户

SQL> `/opt/dm8/samples/instance_script/bookshop/CREATESCHEMA.sql

SQL> `/opt/dm8/samples/instance_script/bookshop/CREATETABLE.sql

SQL> `/opt/dm8/samples/instance_script/bookshop/INSERTSQL.sql

4.2 添加重做日志

SQL> alter database add logfile '/opt/dm8/data/PROED/PROED03.log' size 256;

SQL> alter database add logfile '/opt/dm8/data/PROED/PROED04.log' size 256;

4.3 兼容mysql

SQL> alter system set 'COMPATIBLE_MODE'=4 spfile;

SQL> select * from v$parameter where name like 'COMPA%';

4.4 创建表空间

create tablespace "PROD_TBS" datafile '/opt/dm8/data/PROED/PROD_TBS01.DBF' size 64 autoextend on next 1 maxsize 1024, '/opt/dm8/data/PROED/PROD_TBS02.DBF' size 64 autoextend on next 1 maxsize 1024 ;

4.5 创建用户

create user app identified by "App123456" default tablespace prod_tbs;

grant resource to app;

4.6 创建表

以sysdba用户登录

create table app.emp as select * from resources.employee where 1=2;

create table app.dept as select * from resources.department where 1=2;

GRANT SELECT, INSERT, DELETE, UPDATE, REFERENCES ON APP.EMP TO HR;

GRANT ALL PRIVILEGES ON APP.EMP TO HR;

4.7 赋予修改特定列数据权限

以sysdba用户登录

create user hr identified by "dameng123";

grant resource to hr;

grant select(employeeid,nationalno,loginid),update(employeeid,nationalno,loginid),insert(employeeid,nationalno,loginid) on app.emp to hr;

4.8 导入数据

建立insert.sql文件，赋予dmdba:dinstall权限。

SQL> host more /opt/dm8/samples/insert.sql

insert into app.dept values (1,'xiaoshou');

SQL> start /opt/dm8/samples/insert.sql

SQL> insert into app.dept values (1,'xiaoshou');

影响行数 1

已用时间: 0.486(毫秒). 执行号:814.

SQL> commit;

操作已执行

已用时间: 0.316(毫秒). 执行号:815.

4.9 修改数据

以hr用户登录

update app.emp set PERSONID=1；

commit;

4.10 配置ODBC

tar xzvf unixODBC-2.3.2.tar.gz

cd unixODBC-2.3.2/

./configure --enable-gui=no

make

make install

odbc_config --odbcini

[root@DM etc]# cat odbc.ini

[dm8]

driver=dm8 odbc

server=192.168.0.111

uid=sysdba

pwd=damengdba123

tcp_port=5236

[root@DM etc]# cat odbcinst.ini

[dm8 odbc]

driver=/opt/dm8/drivers/odbc/libdodbc.so

[root@DM software]# odbc_config --version

[root@DM software]# odbc_config --odbcini

[root@DM software]# odbcinst –j

--测试ODBC是否连通

[dmdba@bogon bin]$isql dm8

4.11 备份与恢复

---做一个完整备份，使能够恢复到任意一个时刻。

su – dmdba

mkdir /opt/dm8/bakcup

---将备份存放到/opt/dm8/backup 目录

alter database mount;

alter database archivelog;

---备注：需要注意归档目录属性。

su – dmdba

mkdir /opt/dm8/arch

alter database add archivelog 'DEST=/opt/dm8/arch, TYPE=LOCAL, FILE_SIZE=200,SPACE_LIMIT=1024';

alter database open;

select * from v$dm_arch_ini;

backup database backupset '/opt/dm8/backup/db_full_bak_01';

---将main.dbf 文件删除，利用以上的备份恢复。

SQL> backup database backupset '/opt/dm8/backup/db_full_bak_01';

SQL> host ls -l /opt/dm8/backup/db_full_bak_01

[dmdba@enmoedu1 backup]$ cd /opt/dm8/data/DAMENG/

[dmdba@enmoedu1 DAMENG]$ rm MAIN.DBF

[dmdba@enmoedu1 DAMENG]$ DmServiceDMSERVER stop

[dmdba@enmoedu1 DAMENG]$ ls |grep MAIN.DBF

[dmdba@enmoedu1 DAMENG]$ dmrman

dmrman V8

RMAN>restore database '/opt/dm8/data/DAMENG/dm.ini' tablespace MAIN from backupset '/opt/dm8/backup/db_full_bak_01';

RMAN>restore database '/opt/dm8/data/DAMENG/dm.ini' tablespace MAIN from backupset '/opt/dm8/backup/db_full_bak_01';

RMAN>recover database '/opt/dm8/data/DAMENG/dm.ini' tablespace MAIN;

[dmdba@enmoedu1 DAMENG]$ ls |grep MAIN.DBF

MAIN.DBF

[dmdba@enmoedu1 DAMENG]$ DmServiceDMSERVER start

Starting DmServiceDMSERVER: [ OK ]

[dmdba@enmoedu1 DAMENG]$ disql sysdba/dameng123@localhost:5252

SQL> select file_name,tablespace_name,status from dba_data_files;

SQL> select status$ from v$instance;

---备份定时任务

---创建两个job,一个full_job 每周六，日晚上23：00 做全备，另一个inc_job 每周三，五做增量备份。

---先创建代理环境：

---备注：配置增量备份时要选择“基备份目录”。
