一、服务器配置

1.扩展基础盘

磁盘分区

/sbin/fdisk /dev/vda<<EOF &> /dev/null
p
n
4
 
 
p
w
EOF

硬盘刷新

partx -s /dev/vda
echo "Disk Partition /dev/vda4 Create OK!"
pvcreate /dev/vda4
rootlvname=`df -h|grep "\-root"|awk  '{print  $1}'`
vgname=`vgs|grep klas|awk  '{print  $1}'`
vgextend ${vgname} /dev/vda4
lvextend -L 94.5G ${rootlvname}
xfs_growfs ${rootlvname}
df -h

创建并挂载dmdata数据盘

bash 复制代码

mkdir /dmdata
pvcreate /dev/vdb
pvs

和其他盘用一个VG

bash 复制代码

vgextend klas_host* /dev/vdb
lvextend -L +199.99G /dev/mapper/klas_host*-root
xfs_growfs /dev/mapper/klas_host*-root

2.修改内核参数

添加以下内容

bash 复制代码

cat >> /etc/sysctl.conf <<EOF
fs.file-max = 6815744
fs.aio-max-nr = 1048576
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
vm.dirty_ratio = 80
vm.dirty_expire_centisecs = 500
vm.dirty_writeback_centisecs = 100
kernel.core_pattern = /dmdata/core.%p
vm.swappiness=10
vm.dirty_background_ratio = 0
vm.min_free_kbytes = 2097152
EOF

配置使生效

bash 复制代码

sysctl -p

3.配置时间同步

安装chrony

bash 复制代码

yum install chrony -y

增加配置

bash 复制代码

vi /etc/chrony.conf
#pool pool.ntp.org iburst  # 注释掉这行
#pool 172.30.11.3 iburst   
pool 10.224.198.137 iburst # 新增这行，这个ip是局里的ntp地址

启动chrony并加入开机启动

bash 复制代码

systemctl enable chronyd.service
systemctl restart chronyd.service
systemctl status chronyd.service

关闭防火墙

bash 复制代码

systemctl disable firewalld
systemctl stop firewalld

或者设置firewalld（因NTP使用123/UDP端口协议和chrony协议端口相同，所以允许NTP服务即可。）

firewall-cmd --add-service=ntp --permanent

firewall-cmd --reload

查看chronyd状态

bash 复制代码

chronyc sources;systemctl status chronyd;

5.关闭swap

临时关闭 swap 分区，重启后失效

bash 复制代码

swapoff -a

永久关闭 swap 分区

bash 复制代码

sed -ri 's/.*swap.*/#&/' /etc/fstab

重启操作系统

bash 复制代码

reboot

再次确认

bash 复制代码

free -m

二、达梦环境、软件初始化

1.环境配置

创建dinstall组跟dmdba用户

bash 复制代码

groupadd dinstall -g 1049
useradd dmdba -u 1049 -g dinstall
echo "zjdj_zjj_123" | passwd dmdba --stdin > /dev/null 2>&1
echo "dmdba       ALL=(ALL)       NOPASSWD: ALL" >> /etc/sudoers

修改用户资源限制

bash 复制代码

cat >> /etc/security/limits.conf <<EOF
# 末尾添加
dmdba  soft      nice       0
dmdba  hard      nice       0
dmdba  soft      as         unlimited
dmdba  hard      as         unlimited
dmdba  soft      fsize      unlimited
dmdba  hard      fsize      unlimited
dmdba  soft      nproc      65536
dmdba  hard      nproc      65536
dmdba  soft      nofile     65536
dmdba  hard      nofile     65536
dmdba  soft      core       unlimited
dmdba  hard      core       unlimited
dmdba  soft      data       unlimited
dmdba  hard      data       unlimited
EOF

配置dmdba环境变量

bash 复制代码

tee /home/dmdba/.bash_profil /home/dmdba/.bashrc <<EOF
export DM_HOME="/dm8"
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/dm8/bin
export PATH=$PATH:$DM_HOME/bin:$DM_HOME/tool
EOF

2.达梦软件安装

创建达梦软件安装目录

bash 复制代码

mkdir /dm8
chown dmdba.dinstall /dm8 /dmdata

上传达梦安装包和密钥到root目录下

两个节点分别安装

bash 复制代码

mkdir -p /mnt/dmiso
mount -o loop /root/dm8_20230927_FTarm_kylin10_sp1_64.iso /mnt/dmiso

切换用户

bash 复制代码

su - dmdba
cd /mnt/dmiso

执行安装

bash 复制代码

./DMInstall.bin -i

选择安装程序的语言 1为中文，2为英文，默认回车选择安装语言为中文。

提示是否安装 key 文件，默认Y 同意。

请输入Key文件的路径地址 [dm.key]:

/dmdata/dm06_1_政务应用.key

/dmdata/dm06_2_政务应用.key

选择时区，默认21 即东 8 区。

选择安装类型，默认典型安装（包含所有内容）。

选择软件安装目录，默认安装在/home/dmdba/dmdbms，这里需要选择/dm8

/dm8

确认安装。

安装完成提示使用root用户执行脚本

bash 复制代码

exit
sh /dm8/script/root/root_installer.sh

2.主备集群配置

切换dm用户

bash 复制代码

su - dmdba

初始化实例

bash 复制代码

cd /dm8/bin
./dminit path=/dmdata page_size=32 extent_size=32 charset=1 log_size=2048 db_name=dmdb instance_name=dmdb SYSDBA_PWD="Hn@dameng123" SYSAUDITOR_PWD="Hn@dameng123" SYSSSO_PWD="Hn@dameng123" SYSDBO_PWD="Hn@dameng123"

两个节点都要做，测试达梦机器能否手动开启

bash 复制代码

dmserver /dmdata/dmdb/dm.ini

3.脱机备份数据库

在主机dmdb01上执行以下命令，确认主库 dmap 服务已启动

bash 复制代码

ps -ef |grep dmap

若未启动，则先启动DMAP服务，dmdba用户到安装目录的bin下执行以下命令：

bash 复制代码

./DmAPService start

3.1.主库

dmdba用户启动dmrman工具

bash 复制代码

dmrman use_ap=2

执行 backup 全库

bash 复制代码

backup database '/dmdata/dmdb/dm.ini' backupset '/dmdata/dmdb/bak/full_bak';

使用主库的备份还原备库，将备份的文件/home/dmdba/bakfull拷贝到备库服务器上。

bash 复制代码

scp -r /dmdata/dmdb/bak/full_bak 10.76.18.200:/dmdata/dmdb/bak/

3.2.备库

使用dmrman工具还原备库，dmdba用户执行

bash 复制代码

dmrman

进入dmrman工具交互界面，执行restore

bash 复制代码

restore database '/dmdata/dmdb/dm.ini' from backupset '/dmdata/dmdb/bak/full_bak';

完成后执行recover

bash 复制代码

recover database '/dmdata/dmdb/dm.ini' from backupset '/dmdata/dmdb/bak/full_bak';

最后执行recover update db_magic

bash 复制代码

recover database '/dmdata/dmdb/dm.ini' update db_magic;

4.达梦配置文件修改

4.1.主备库修改dm.ini

主库dmdb01上修改以下参数值：

bash 复制代码

sed -i 's/\(INSTANCE_NAME\) *= [^ ]*/\1 = DM01/g' /dmdata/dmdb/dm.ini;
sed -i 's/\(MAL_INI\) *= [^ ]*/\1 = 1/g' /dmdata/dmdb/dm.ini;
sed -i 's/\(ARCH_INI\) *= [^ ]*/\1 = 1/g' /dmdata/dmdb/dm.ini;

sed -i 's/\(ENABLE_OFFLINE_TS\) *= [^ ]*/\1 = 2/g' /dmdata/dmdb/dm.ini;
sed -i 's/\(ENABLE_ENCRYPT\) *= [^ ]*/\1 = 0/g' /dmdata/dmdb/dm.ini;
cat /dmdata/dmdb/dm.ini |grep 'INSTANCE_NAME\|MAL_INI\|ARCH_INI\|ENABLE_OFFLINE_TS\|ENABLE_ENCRYPT\|ALTER_MODE_STATUS'

bash 复制代码

vi /dmdata/dmdb/dm.ini
INSTANCE_NAME                   = DM01
ENABLE_ENCRYPT                  = 0
ALTER_MODE_STATUS               = 1
ENABLE_OFFLINE_TS               = 2
MAL_INI                         = 1
ARCH_INI                        = 1

备库dmdb02上修改以下参数值：

bash 复制代码

sed -i 's/\(INSTANCE_NAME\) *= [^ ]*/\1 = DM02/g' /dmdata/dmdb/dm.ini;
sed -i 's/\(MAL_INI\) *= [^ ]*/\1 = 1/g' /dmdata/dmdb/dm.ini;
sed -i 's/\(ARCH_INI\) *= [^ ]*/\1 = 1/g' /dmdata/dmdb/dm.ini;
sed -i 's/\(ALTER_MODE_STATUS\) *= [^ ]*/\1 = 1/g' /dmdata/dmdb/dm.ini;
sed -i 's/\(ENABLE_OFFLINE_TS\) *= [^ ]*/\1 = 2/g' /dmdata/dmdb/dm.ini;
sed -i 's/\(ENABLE_ENCRYPT\) *= [^ ]*/\1 = 0/g' /dmdata/dmdb/dm.ini;
cat /dmdata/dmdb/dm.ini |grep 'INSTANCE_NAME\|MAL_INI\|ARCH_INI\|ENABLE_OFFLINE_TS\|ENABLE_ENCRYPT\|ALTER_MODE_STATUS'

bash 复制代码

INSTANCE_NAME                   = DM02
ENABLE_ENCRYPT                  = 0
ALTER_MODE_STATUS               = 1
ENABLE_OFFLINE_TS               = 2
MAL_INI                         = 1
ARCH_INI                        = 1

4.2.主备库修改归档配置文件dmarch.ini

vi /dmdata/dmdb/dmarch.ini

主库dmdb01上添加以下内容：

bash 复制代码

[ARCHIVE_REALTIME1]
ARCH_TYPE     = REALTIME
ARCH_DEST     = DM02

[ARCHIVE_LOCAL1]
ARCH_TYPE     = LOCAL
ARCH_DEST     = /dmdata/arch
ARCH_FILE_SIZE    = 2048
ARCH_SPACE_LIMIT  = 102400

备库dmdb02上添加以下内容

bash 复制代码

[ARCHIVE_REALTIME1]
ARCH_TYPE     = REALTIME
ARCH_DEST     = DM01

[ARCHIVE_LOCAL1]
ARCH_TYPE     = LOCAL
ARCH_DEST     = /dmdata/arch
ARCH_FILE_SIZE    = 2048
ARCH_SPACE_LIMIT  = 102400

4.3.主备库配置MAL系统配置文件dmmal.ini

主备库2个节点文件内容要相同。

vi /dmdata/dmdb/dmmal.ini

bash 复制代码

MAL_CHECK_INTERVAL   = 5
MAL_CONN_FAIL_INTERVAL  = 15

[MAL_INST1]
 MAL_INST_NAME    = DM01
 MAL_HOST         = 10.76.18.199
 MAL_PORT         = 7336
 MAL_INST_HOST    = 10.76.18.199
 MAL_INST_PORT    = 5236
 MAL_DW_PORT      = 7436
 MAL_INST_DW_PORT = 7536

[MAL_INST2]
 MAL_INST_NAME    = DM02
 MAL_HOST         = 10.76.18.200
 MAL_PORT         = 7336
 MAL_INST_HOST    = 10.76.18.200
 MAL_INST_PORT    = 5236
 MAL_DW_PORT      = 7436

4.4.配置主备库守护进程配置文件dmwatcher.ini

vi /dmdata/dmdb/dmwatcher.ini

主备库2节点文件内容要相同。

bash 复制代码

[GRP_DW]
DW_TYPE    = GLOBAL
DW_MODE    = MANUAL
DW_ERROR_TIME     = 30
INST_RECOVER_TIME  = 60
INST_ERROR_TIME   = 20
INST_OGUID         = 453402
INST_INI           = /dmdata/dmdb/dm.ini
INST_AUTO_RESTART  = 1
INST_STARTUP_CMD   = /dm8/bin/dmserver

4.5.配置主备库dmmonitor.ini

配置监视器(可以在主备任意节点配置，也可以主备节点都配置，局里主备库非自动切换模式，该进程手动启动)

新建非确认监视器配置文件 dmmonitor.ini，执行以下命令：

bash 复制代码

cat > /dmdata/dmdb/dmmonitor.ini <<EOF
# 添加以下内容：
MON_DW_CONFIRM    = 0
MON_LOG_PATH    = /dm8/log
MON_LOG_INTERVAL  = 60
MON_LOG_FILE_SIZE   = 200
MON_LOG_SPACE_LIMIT  = 1024

[GRP_DW]
MON_INST_OGUID    = 453402
MON_DW_IP     = 10.76.18.199:7436
MON_DW_IP     = 10.76.18.200:7436
EOF

4.6.配置SQL日志

vi /dmdata/dmdb/sqllog.ini

bash 复制代码

BUF_TOTAL_SIZE          = 10240         #SQLs Log Buffer Total Size(K)(1024~1024000)
BUF_SIZE                = 1024          #SQLs Log Buffer Size(K)(50~409600)
BUF_KEEP_CNT            = 6             #SQLs Log buffer keeped count(1~100)
 
[SLOG_ALL]
    FILE_PATH    = ../log
    PART_STOR    = 1
    SWITCH_MODE  = 2
    SWITCH_LIMIT   = 512
    ASYNC_FLUSH   = 1
    FILE_NUM = 5
    ITEMS    = 0
    SQL_TRACE_MASK  = 2:3:25:28
    MIN_EXEC_TIME = 1500
    USER_MODE   = 0
    USERS =
    EXECTIME_PREC_FLAG = 0

    [SLOG_ERROR]
    SQL_TRACE_MASK = 23
    FILE_PATH      = ../log

    [SLOG_DDL]
    SQL_TRACE_MASK = 3

    [SLOG_LONG_SQL]
    SQL_TRACE_MASK = 25
    MIN_EXEC_TIME = 60000

5.手动启动数据库实例、dmwatcher和dmmonitor

5.1.手动启动数据库实例并进行初始化配置

以mount方式启动数据库实例，使用dmdba用户，执行以下命令（主备库都执行）：

bash 复制代码

dmserver /dmdata/dmdb/dm.ini mount

在新的终端使用 disql 工具连接数据库：

bash 复制代码

disql sysdba/'"Hn@dameng123"'

主备库都修改 oguid，执行以下命令：

bash 复制代码

sp_set_oguid(453402);

开启归档模式

bash 复制代码

alter database archivelog;

主库dmdb01上修改数据库模式为 primary，执行以下命令：

bash 复制代码

alter database primary;

备库dmdb02上修改数据库模式为 standby，执行以下命令：

bash 复制代码

alter database standby;

查看oguid

bash 复制代码

SELECT OGUID FROM V$INSTANCE;

6.手动启动dmwatcher

6.1.启动守护进程

dmdba 用户下，到数据库安装目录的bin下执行以下命令（主备库都执行）：

bash 复制代码

dmwatcher /dmdata/dmdb/dmwatcher.ini

守护进程启动后，会将 mount 状态的实例启动到 open状态。

6.2.手动启动dmmonitor

bash 复制代码

vim /dmdata/dmdb/dmmonitor.ini

bash 复制代码

[monitor]         2023-12-08 16:31:58: DMMONITOR[4.0] V8

可能遇到的问题：如果实例没有自动启动到open状态，需要手动强制启动主备实例到open状态

关闭dmwatcher

主备节点分别disql执行：

sp_set_para_value(1,'ALTER_MODE_STATUS',1);

alter database open force;

7.主备节点手动切换

dmmonitor查看全局信息

bash 复制代码

dmmonitor /dmdata/dmdb/dmmonitor.ini

bash 复制代码

8.注册服务

以上启动为前台方式启动，仅用户搭建过程中验证配置。配置没问题后需要将实例，守护进程配置为系统服务。使用 root 用户，到数据库安装目录的/dm8/script/root下。

注册守护进程服务（主备库都执行）。

bash 复制代码

/dm8/script/root/dm_service_installer.sh -t dmwatcher -p dw -watcher_ini /dmdata/dmdb/dmwatcher.ini

注册数据库实例服务（主备库都执行）：

bash 复制代码

/dm8/script/root/dm_service_installer.sh -t dmserver -p dw -dm_ini /dmdata/dmdb/dm.ini

以服务方式启动

执行以下命令，启动数据库实例：

systemctl start DmServicedw

执行以下命令，启动守护进程：

systemctl start DmWatcherServicedw

节点2使用dmmonitor监控

[dmdba@0002 ~]$ dmmonitor /dmdata/dmdb/dmmonitor.ini

使用 disql 客户端登录主库，创建测试表，插入数据，执行以下命令：

disql SYSDBA/'"Hn@dameng123"'@10.223.189.18:5236

SQL 提示符下执行以下命令：

create table test(id int);

insert into test values (1);

commit;

使用disql客户端登录备库，查询测试表验证，执行以下命令：

disql SYSDBA/'"Hn@dameng123"'@10.223.189.19:5236

SQL 提示符下执行以下命令：

select * from test;

查看数据是否正常同步。

```

主节点上创建备份账号

```shell

账号具备BACKUP DATABASE和RESTORE DATABASE权限和部分查询权限，

"SYS"."V$DM_INI"，

"SYS"."V$BACKUPSET"

"SYS"."V$BACKUPSET_SUBS"

"SYS"."V$BACKUPSET_TABLE"

"SYS"."V$BACKUPSET_SEARCH_DIRS"

"SYS"."V$BACKUPSET_BKP"

"SYS"."V$BACKUPSET_DBF"

"SYS"."V$BACKUPSET_DBINFO"

"SYS"."V$BACKUPSET_ARCH"

"SYS"."V$CIPHERS"

"SYS"."V$RLOG"

"SYS"."V$DM_MAL_INI"

"SYS"."V$DM_ARCH_INI"

"SYS"."V$DATAFILE"

"SYS"."V$RLOGFILE"

添加这些表的查询权限

create user forbackup identified by "uD_NS4l0BhYO7q";

grant create session to forbackup;

grant backup database to forbackup;

grant restore database to forbackup;

grant select on "SYS"."V$DM_INI" to forbackup;
