3.关闭防火墙
-
使用root权限登录到Red Hat系统的终端。
-
停止当前运行的防火墙服务。可以使用以下命令：
systemctl stop firewalld -
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 -
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。
-
重新启动系统，以使更改生效。
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。

4.下载repo配置文件。
wget http://mirrors.aliyun.com/repo/Centos-7.repo
将文件中所有的$releasever**更换为**7，否则无法使用。
mv Centos-7.repo /etc/yum.repos.d/
vi /etc/yum.repos.d/Centos-7.repo
%s/$releasever/7/g
5下载KEY文件：
[redhat@root ~]$ cd /etc/yum.repos.d/
mv redhat.repo redhat.repo.bak
关闭订阅插件提示
[redhat@root ~]$ vi /etc/yum.conf
plugins=0
[redhat@root ~]$ vim /etc/yum/pluginconf.d/subscription-manager.conf
[main]
enabled=0 #将它禁用掉
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
安装相关软件
## 安装常用软件
yum install -y vim tree net-tools unzip
## 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
配置hosts
ora1
hostnamectl set-hostname ora1
orastd1
hostnamectl set-hostname orastd1
orastd2
hostnamectl set-hostname orastd2
主库备库都要添加进去
echo "192.168.134.249 ora1" >> /etc/hosts
echo "192.168.134.250 orastd1" >> /etc/hosts
echo "192.168.134.251 orastd2" >> /etc/hosts
主库安装数据库
配置目录
mkdir /opt/oracle
先把下载的包传到soft目录下
mkdir /soft
cd /soft
rpm -ivh oracle-database-preinstall-19c-1.0-1.el7.x86 64.rpm
yum -y install compat-libcap1 ksh
yum -y install compat-libstdc++-33
yum -y install libaio-devel
yum -y install libstdc++-devel
修改密码
passwd oracle
手工目录的授权
chown -R oracle:oinstall /opt/oracle
chmod -R 775 /opt/oracle
安装oracle-database-ee：
rpm -ivh oracle-database-ee-19c-1.0-1.x86_64.rpm
准备配置文件
cd /etc/sysconfig
cp oracledb_ORCLCDB-19c.conf oracledb_orcl-19c.conf
vi /etc/sysconfig/oracledb_orcl-19c.conf
不要修改
cd /etc/init.d
cp oracledb_ORCLCDB-19c oracledb_orcl-19c
vi /etc/init.d/oracledb_orcl-19c
下面是在vi里面执行
:%s/ORCLCDB/orcl/g
:%s/ORCLPDB1/orclpdb/g
（为了全局替换）
然后在修改下面的内容：
创建数据库
/etc/init.d/oracledb_orcl-19c configure
检查环境:
su - oracle
ps -ef | grep smon
echo $ORACLE_HOME
lsnrctl status
测试停止、启动
/etc/init.d/oracledb itpuxdb-19c
Usage: /etc/init.d/oracledb_itpuxdb-19c {start|stoprestart|configure)
/etc/init.d/oracledb_orcl-19c stop
/etc/init.d/oracledb_orcl-19c start
环境变量配置
su - oracle
echo "export LANG=en_US" >>~/.bash_profile
echo "export ORACLE_BASE=/opt/oracle">>~/.bash_profile
echo "export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1">> ~/.bash_profile

echo "export PATH=$PATH:/opt/oracle/product/19c/dbhome_1/bin" >> ~/.bash_profile
source ~/.bash_profile
env | grep ORACLE
这样主库就搭建成功啦
2.一级备库的搭建
(前面一点都差不多，但是没有了**准备配置文件：创建数据库)
配置hosts
主库备库都要添加进去
echo "192.168.134.249 ora1" >> /etc/hosts
echo "192.168.134.250 orastd1" >> /etc/hosts
echo "192.168.134.251 orastd2" >> /etc/hosts
关闭防火墙
systemctl stop firewalld.service
systemctl disable firewalld.service
配置目录
mkdir /opt/oracle
这个是配置目录，如果有的话就不用创建啦
准备预先安装的包
先把下载的包传到soft目录下
mkdir /soft
rpm -ivh oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
注意：（这里会出现问题）
根据提示安装所需要的包：(如)
yum -y install compat-libcap1 ksh
yum -y install compat-libstdc++-33
yum -y install libaio-devel
yum -y install libstdc++-devel
修改密码：

lsnrctl status(这个会出错误没关系,下面会配好)
环境变量配置
su - oracle
echo "export LANG=en_US">>~/.bash_profile
echo "export ORACLE_BASE=/opt/oracle">>~/.bash_profile
echo "export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1">> ~/.bash_profile

env |grep ORACLE
备库的数据库环境装好了。
三、主备库的实施配置
准备备库1监听配置
vi /opt/oracle/product/19c/dbhome_1/network/admin/listener.ora
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS =(PROTOCOL =TCP)(HOST =orastd1)(PORT = 1521))
(ADDRESS =(PROTOCOL=IPC)(KEY=EXTPROC1521))
)
)
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=orcldg)
(SID_NAME=orcldg)
(ORACLE_HOME=/opt/oracle/product/19c/dbhome_1)
)
)
:wq
然后检查监听是否配置成功
lsnrctl start
lsnrctl status
准备备库2监听配置
vi /opt/oracle/product/19c/dbhome_1/network/admin/listener.ora
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS =(PROTOCOL =TCP)(HOST =orastd2)(PORT = 1521))
(ADDRESS =(PROTOCOL=IPC)(KEY=EXTPROC1521))
)
)
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=orcldgs)
(SID_NAME=orcldgs)
(ORACLE_HOME=/opt/oracle/product/19c/dbhome_1)
)
)
:wq
然后检查监听是否配置成功
lsnrctl start
lsnrctl status
主库配置
1.打开强制日志
su - oracle
sqlplus "/as sysdba"
alter database force logging;
2.设置为归档模式
alter system set db_recovery_file_dest_size=5g;
alter system set db_recovery_file_dest='/opt/oracle';
shutdown immediate
startup mount;
alter database archivelog;
alter database open;
alter system switch logfile;
可以出查看一下是否有归档文件
cd /opt/oracle/ITPUXDB/archivelog/
3.创建日志文件 如果主库有三个了（那就要创建四个）
select * from v$log;
select * from v$logfile;
alter database add standby logfile group 4 '/opt/oracle/oradata/ORCLDGS/stredo04.log' size 200m;
alter database add standby logfile group 5 '/opt/oracle/oradata/ORCLDGS/stredo05.log' size 200m;
alter database add standby logfile group 6 '/opt/oracle/oradata/ORCLDGS/stredo06.log' size 200m;
alter database add standby logfile group 7 '/opt/oracle/oradata/ORCLDGS/stredo07.log' size 200m;
主备库监听tnsnames.ora:
vi /opt/oracle/product/19c/dbhome_1/network/admin/tnsnames.ora
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = ora1)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
ORCLDG =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = orastd1)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcldg)
)
)
ORCLDGS =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = orastd2)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcldgs)
)
)
（主库只要加ITPUXDG，备库全加上）
测试
tnsping ORCL
tnsping ORCLDG
tnsping ORCLDGS
准备数据库密码文件
主库：
orapwd file='opt/oracle/product/19c/dbhome_1/dbs/orapworcl' password=hsl-123456
orapwd file='./orapworcl' password=orcl-123
备库：
cd /opt/oracle/product/19c/dbhome_1/dbs
scp orapworcl 192.168.134.250:/opt/oracle/product/19c/dbhome_1/dbs/orapworcl
mv orapworcl orapworcldg
scp orapworcl 192.168.134.251:/opt/oracle/product/19c/dbhome_1/dbs/orapworcl
mv orapworcl orapworcldgs
登录
主库：
sqlplus "sys/123456@orcl as sysdba"
准备参数文件了。
主库：
create pfile='/opt/oracle/pfile.ora' from spfile;
（等会有改参数，这个是备份一份，然后传到备库里面在改参数）
然后在把pfile传给备库
scp /opt/oracle/pfile.ora 192.168.134.250:/opt/oracle/
scp /opt/oracle/pfile.ora 192.168.134.251:/opt/oracle/

备库参数：
cd /opt/oracle
vi pfile.ora
#先把"*."前面的都删了,把itpuxdb改成itpuxdg,在添加下面的。

备库备库创建需要的目录：
mkdir -p /opt/oracle/admin/orcldg/adump
mkdir -p /opt/oracle/oradata/ORCLDG
二级备库参数：
cd /opt/oracle
vi pfile.ora
db_unique_name='orcldgs'

启动到nomunt(一级备库);
sqlplus "sys/123456@orcldg as sysdba"
startup pfile='/opt/oracle/pfile.ora' nomount;
create spfile from pfile='/opt/oracle/pfile.ora';
shutdown immediate;
startup nomount;
启动到nomunt(二级备库);
sqlplus "sys/123456@orcldgs as sysdba"
startup pfile='/opt/oracle/pfile.ora' nomount;
create spfile from pfile='/opt/oracle/pfile.ora';
shutdown immediate;
startup nomount;
打开时出现了
ORA-00845: MEMORY_TARGET not supported on this system
那就是 memory_target大于了/dev/shm,重新调整数据库参数MEMORY_TARGET的大小，要下于/dev/shm的大小
查看/dev/shm的大小
df -h | grep shm
使用创建dataguard数据库(主库备库都可以)
rman target sys/123456@orcl auxiliary sys/123456@orcldg
duplicate target database for standby from active database;
如果在传输过程中，出现网络中断，或者备库异常down机等突发情况导致的duplicate中断，那么后面可以尝试下面恢复手段：
1、备库重启至nomount状态
2、再次执行duplicate命令，此时如果已经传输过去的数据文件不会再次传输，会跳过接着继续传输进行后面步骤，非常简单。但是如果再次尝试还是有网络限制，可能就需要手动处理的方式。

直接关闭数据库
b、下一步
此时将备库重启至nomount状态(使用原先的pfile即可)
sqlplus "sys/123456@orcldgs as sysdba"
startup pfile='/opt/oracle/pfile.ora' nomount;
create spfile from pfile='/opt/oracle/pfile.ora';
shutdown immediate;
startup nomount;
c、再次执行duplicate命令
rman target sys/123456@orcl auxiliary sys/123456@orcldg
duplicate target database for standby from active database dorecover;
可以看到成功连上了system01.dbf
四、检查测试：
查看dataguard状态：
select NAME,OPEN_MODE,PROTECTION_MODE,DATABASE_ROLE,SWITCHOVER_STATUS from v$database;
启动dataguard数据同步：
sqlplus "/as sysdba"
alter database recover managed standby database disconnect from session; 开启同步
关闭dataguard数据同步：
alter database recover managed standby database cancel;
以上步骤知识了解，不要执行，从下开始再执行。
启动adg模式的备库：
上述备库的数据库是nomount状态，再执行完rman后
alter database open;
alter database recover managed standby database disconnect from session;
主库测试：
alter system switch logfile;
主备库检查dataguard状态：
select NAME,OPEN_MODE,PROTECTION_MODE,DATABASE_ROLE,SWITCHOVER_STATUS from v$database;
dataguard数据同步测试

开始搭建二级备库
主库设置
alter system set log_archive_config = 'dg_config=( orcl,orcldg,orcldgs)' scope=both sid='*';
alter system set db_file_name_convert='ORCLDG','ORCL' scope=spfile;
alter system set log_file_name_convert='ORCLDG','ORCL' scope=spfile;
alter system set fal_server='ORCLDG','ORCLDGS' scope=both;
alter system set fal_client='ORCL' scope=both;
4.1 设置一级备库参数（一级备库）
alter system set log_archive_config = 'dg_config=( orcl,orcldg,orcldgs)' scope=both sid='*';
alter system set log_archive_dest_5='service=orcldgs lgwr async compression=enable valid_for=(all_logfiles,standby_role) db_unique_name=orcldgs' scope=both;
alter system set log_archive_dest_state_5='enable' scope=both;
alter system set fal_server='orcl','orcldgs' scope=both;
alter system set fal_client='orcldg' scope=both;
alter system set db_file_name_convert='ORCLDG','ORCLDGS' scope=spfile;
alter system set log_file_name_convert='ORCLDG','ORCLDGS' scope=spfile;
alter system set standby_file_management=AUTO scope=both;
select APPLIED,SEQUENCE# from v$archived_log;
二级备库
