手把手教使用静默 搭建Oracle 19c 一主一备ADG集群

一、环境搭建

主机	IP
ora19	192.168.134.239
ora19std	192.168.134.240

1.配置yum源

1.配置网络yum源

1.删除redhat7.0系统自带的yum软件包；

rpm -qa|grep yum >oldyum.pkg  备份原信息rpm -qa|grep yum|xargs rpm -e --nodeps  不检查依赖，直接删除rpm包

2.自行下载所需要的软件包。包名会更新，根据当前最新的下载。如有有依赖问题，下载依赖包进行安装。

阿里云网络源地址：https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/

网易163网络源地址：http://mirrors.163.com/ CentOS

网络源地址：http://centos.ustc.edu.cn/centos/

打开网页，ctrl+f 搜索相关yum包：http://mirrors.163.com/centos/7/os/x86_64/Packages/

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-168.el7.centos.noarch.rpm  wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-langpacks-0.4.2-7.el7.noarch.rpm  wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm  wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpmwget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-rhn-plugin-2.0.1-10.el7.noarch.rpm  wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-utils-1.1.31-54.el7_8.noarch.rpm

3.根据依赖项安装；

rpm -ivh yum-*

4.下载repo配置文件。

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/centos/7/atomic/x86_64/repo/CentOS-Base.repo

将文件中所有的$releasever**更换为**7，否则无法使用。
sed -i 's/$releasever/7/g' /etc/yum.repos.d/CentOS-Base.repo

5下载KEY文件：

wget -O /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 http://mirrors.163.com/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7

6.清理yum缓存。将服务器软件包信息缓存至本地，提高搜索安装效率

yum -y clean all && yum -y makecache

2.配置本地yum源

yum源配置：

## 挂载镜像
mkdir -p /mnt/cdrom
mount /dev/sr0 /mnt/cdrom
## 编辑yum源文件
cd /etc/yum.repos.d/
vi yum.repo[base]
name=base
baseurl=file:///mnt/cdrom
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release[root@redhat yum.repos.d] yum clean all

2.配置vnc

nmcli connection modify ens33 ipv4.addresses 192.168.134.240/24 ipv4.gateway 192.168.134.2 ipv4.method manual autoconnect yes

1.安装vncserver

yum install tigervnc-server

vncserver

2.关闭selinux

sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
setenforce 0
getenforce

3.关闭防火墙

1. 使用root权限登录到Red Hat系统的终端。

2. 停止当前运行的防火墙服务。可以使用以下命令：

   systemctl stop firewalld
   

3. 禁止防火墙服务在系统启动时自动启动。可以使用以下命令：

   systemctl disable firewalld
   

4. 确认防火墙服务已停止并禁用。可以使用以下命令验证：

   systemctl status firewalld
   

   如果输出显示 “inactive”，则表示防火墙服务已成功停止并禁用。

5. 重新启动系统，以使更改生效。

3.hosts文件配置

---

配置hostname：

hostnamectl set-hostname ora19
hostnamectl set-hostname ora19std

配置hosts文件：

cat <<EOF>>/etc/hosts
#Public IP
192.168.134.239     ora19
192.168.134.240     ora19std
EOF

二、准备阶段

## 安装Oracle依赖包
yum install -y binutils compat-libcap1 compat-libstdc++-33 compat-libstdc++-33.i686 glibc glibc.i686 glibc-devel glibc-devel.i686 ksh libaio libaio.i686 libaio-devel libaio-devel.i686 libX11 libX11.i686 libXau libXau.i686 libXi libXi.i686 libXtst libXtst.i686 libgcc libgcc.i686 libstdc++ libstdc++.i686 libstdc++-devel libstdc++-devel.i686 libxcb libxcb.i686 make nfs-utils net-tools smartmontools sysstat unixODBC unixODBC-devel gcc gcc-c++ libXext libXext.i686 zlib-devel zlib-devel.i686

2.用户与组：

## 创建oinstall、dba组与oracle用户
groupadd -g 54321 oinstall
groupadd -g 54322 dba
useradd -u 9999 -g oinstall -G dba oracle
## 设置oracle用户密码
echo "oracle:123456" | chpasswd

3.修改内核参数：

## 修改内核参数文件
cat >> /etc/sysctl.conf << EOF
## add for oracle
fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824

oracle soft stack 10240
oracle hard stack 32768
oracle hard memlock 134217728
oracle soft memlock 134217728
EOF

5.配置用户环境变量：

su - oracle
vi ~/.bash_profile## 加入以下配置到文件尾#日志存放位置
export TMP=/tmp
export TMPDIR=$TMP#主机名
export ORACLE_HOSTNAME=ora19
#库名称
export ORACLE_UNQNAME=oracle
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.2.0.1/db_1

mkdir /u01/app
mkdir /u01/app/oracle
mkdir /u01/app/oradata
mkdir /u01/app/archive
mkdir /u01/app/oracle/oraInventory
mkdir -p /u01/app/oracle/product/12.2.0.1/db_1
chown -R oracle:oinstall /u01/app/
chmod -R 775 /u01/app/

7.安装Oracle软件

下载Oracle安装文件：
下载地址

上传文件到服务器，并将压缩包授权给oracle后用oracle用户解压到$ORACLE_HOME文件夹下

su - root
cd /soft
chown -R oracle:oinstall /soft
su - oracle -c "unzip -q /soft/LINUX.X64_193000_db_home.zip -d /u01/app/oracle/product/19.3.0/db/"

编辑db_install.rsp:

cd $ORACLE_HOME/install/response
cp db_install.rsp /soft
vim /soft/db_install.rsporacle.install.option=INSTALL_DB_SWONLY
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/u01/app/oracle/oraInventory

NSN_NAMES={"EXTPROC_CONNECTION_DATA"}
NSN_SERVICE={"PLSExtProc"}
NSN_PROTOCOLS={"TCP;HOSTNAME;1521"}
EOFnetca -silent -responseFile /soft/netca.rsp

二、主库配置

1. 开启归档

查看oracle归档状态:

archive log list

关闭数据库:

shutdown immediate;

启动数据库至mount状态:

startup mount;

修改归档位置:

alter system set log_archive_dest_1='location=/u01/app/archive';

/u01/app/archive用于存放归档文件的目录，如果在系统中不存在需要建立并授权给oracle用户

启用归档模式和强制归档:

alter database archivelog;
alter database force logging;
alter database open;

查看修改后的归档状态:

archive log list;

切换在线日志，验证归档是否正常:

alter system switch logfile;
!ls /u01/app/archive

2. redo日志

查询现有redo日志的数量:

select group#,type,member from v$logfile;

查询现有redo日志的容量:

select group#,bytes/1024/1024 as MB,status from v$log;

创建standby日志组:

容量要和redo相同，数量是redo当前数量+1

alter database add standby logfilegroup 6 ('/u01/app/oradata/ORACLE/standby_redo04.log') size 200m reuse,group 7 ('/u01/app/oradata/ORACLE/standby_redo05.log') size 200m reuse, group 8 ('/u01/app/oradata/ORACLE/standby_redo06.log') size 200m reuse, group 9 ('/u01/app/oradata/ORACLE/standby_redo07.log') size 200m reuse;

确认状态:

select group#,status,used from v$standby_log;

3. 文件传输

口令文件:

cd $ORACLE_HOME/dbs 
cp orapworacle /soft/orapworaclestd

参数文件:

sqlplus / as sysdba 
create pfile  from spfile;
exit

vim initoracle.ora  #数据库唯一名称 
*.db_unique_name='oracle' 
*.log_archive_config='dg_config=(oracle,oraclestd)' 
#fal_client填写本机数据库唯一名称 
*.fal_client='oracle'  *.fal_server='oraclestd' *.log_archive_dest_1='LOCATION=/u01/app/archive valid_for=(all_logfiles,all_roles) db_unique_name=oracle' *.log_archive_dest_2='service=oraclestd lgwr async valid_for=(online_logfiles,primary_role) db_unique_name=oraclestd' *.log_archive_format='%t_%s_%r.arc' *.db_file_name_convert='/u01/app/oradata/ORACLESTD/','/u01/app/oradata/ORACLE/' *.log_file_name_convert='/u01/app/oradata/ORACLESTD/','/u01/app/oradata/ORACLE/' 
STANDBY_FILE_MANAGEMENT=AUTO

启用新的参数文件:

备份之前的spfile

create pfile='/soft/spfile.bak' from spfile;

启用新的

shutdown immediate;
create spfile from pfile;
startup;

传输文件到备库:

scp /soft/orapworaclestd oracle@ora19std:/soft
scp $ORACLE_HOME/dbs/initoracle.ora oracle@ora19std:/soft/initoraclestd.ora

4. tns 配置

cat tnsnames.oraORACLE =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = ora19)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = oracle)))LISTENER_ORACLE =(ADDRESS = (PROTOCOL = TCP)(HOST = ora19)(PORT = 1521))ORACLESTD =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = ora19std)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = oraclestd)))

5. 静态监听

特别注意：ORACLE_HOME的路径的db_home1后面不要有’/’，不然会导致sqlplus sys/oracle@oracle as sysdba报错ORA-12537

cd /u01/app/oracle/product/12.2.0.1/db_1/network/admin
LISTENER =(DESCRIPTION_LIST =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = ora19)(PORT = 1521))(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))))SID_LIST_LISTENER =(SID_LIST =(SID_DESC =(GLOBAL_DBNAME = oracle)(ORACLE_HOME = /u01/app/oracle/product/12.2.0.1/db_1)(SID_NAME = oracle)))

6. 监听重载

lsnrctl reload

7. 网络连接测试

tnsping oracle 
tnsping oraclestd

三、备库配置

1. 文件处理

cd /soft
cp orapworaclestd initoraclestd.ora $ORACLE_HOME/dbs
修改参数文件
*.audit_file_dest='/u01/app/oracle/admin/oraclestd/adump' 
*.control_files='/u01/app/oradata/ORACLESTD/control01.ctl','/u01/app/oradata/ORACLESTD/control02.ctl'  
*.db_unique_name='oraclestd' 
*.log_archive_config='dg_config=(oracle,oraclestd)' 
*.fal_client='oraclestd' 
*.fal_server='oracle' 
*.log_archive_dest_1='LOCATION=/u01/app/archive valid_for=(all_logfiles,all_roles) db_unique_name=oraclestd' 
*.log_archive_dest_2='service=oracle lgwr async valid_for=(online_logfiles,primary_role) db_unique_name=oracle' 
*.log_archive_format='%t_%s_%r.arc' 
*.db_file_name_convert='/u01/app/oradata/ORACLESTD/','/u01/app/oradata/ORACLE/' 
*.log_file_name_convert='/u01/app/oradata/ORACLESTD/','/u01/app/oradata/ORACLE/'

2. 启动备库到nomount

export ORACLE_SID=oraclestd
sqlplus / as sysdba 
create spfile from pfile; 
startup nomount;# 修改参数standby_file_management
alter system set standby_file_management=MANUAL;

3. tns 配置

cat tnsnames.oraORACLE =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = ora19)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = oracle)))LISTENER_ORACLE =(ADDRESS = (PROTOCOL = TCP)(HOST = ora19)(PORT = 1521))ORACLESTD =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = ora19std)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = oraclestd)))

4. 静态监听

特别注意：ORACLE_HOME的路径的db_home1后面不要有’/’，不然会导致sqlplus sys/oracle@oracle as sysdba报错ORA-12537

LISTENER =(DESCRIPTION_LIST =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = ora19std)(PORT = 1521))(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))))SID_LIST_LISTENER =(SID_LIST =(SID_DESC =(GLOBAL_DBNAME = oraclestd)(ORACLE_HOME = /u01/app/oracle/product/12.2.0.1/db_1)(SID_NAME = oraclestd)))

5. 监听重载

lsnrctl reload

6. 网络连接测试

tnsping oracle 
tnsping oraclestdsqlplus sys/oracle@oracle as sysdba
sqlplus sys/oracle@oraclestd as sysdba

四、构建备库

主库执行

登录到rman:
connected状态，主库显示DBID，备库为not mounted状态是正确的

rman target sys/oracle@oracle auxiliary sys/oracle@oraclestd

构建备库:

run {
allocate channel ch001 type disk;
allocate channel ch002 type disk;
allocate channel ch003 type disk;
allocate channel ch004 type disk;
allocate auxiliary channel ch005 type disk;
allocate auxiliary channel ch006 type disk;
duplicate target database for standby from active database nofilenamecheck using compressed backupset;
release channel ch001;
release channel ch002;
release channel ch003;
release channel ch004;
release channel ch005;
release channel ch006;
}

备库执行

查询备库状态是否已经mount：

select open_mode from v$database;

打开备库：

alter database open;

检查文件:

select name from v$datafile;select name from v$tempfile;select group#,type,member from v$logfile order by 2,1;

开启日志应用:

alter database recover managed standby database using current logfile disconnect;

检查数据同步状态:
通过判断transport lag和apply lag两个参数的DATUM_TIME值来判断备库是否在应用主库的日志文件
如果多次查询DATUM_TIME值保持不变，则说明备库已经停止从主库接收数据了

select name,value,TIME_COMPUTED,DATUM_TIME 
from v$dataguard_stats;

检查MRP进程状态:

select process,status from v$managed_standby;

查看数据库打开状态:
READ ONLY WITH APPLY代表ADG启动成功

select open_mode from v$database;

到此单实例一主一备搭建完成，接下来你可以进行一些ADG操作
