Note before installation
1, The remaining memory space must be greater than 120MB
2, The swap space must be greater than 150MB
Configure swap space
dd if=/dev/zero of=/home/swap bs=1M count=2048
mkswap /home/swap
chmod 600 /home/swap
swapon /home/swap

1, To configure yum Source
mv CentOS-Base.repo CentOS-Base.repo.bak
wget -O /etc/yum.repos.d/CentOSBase.repo http://mirrors.aliyun.com/repo/Centos-7.repo

2, Installation and compilation environment
yum -y install gcc gcc-c++ gcc-g77 autoconf automake zlib* fiex* libxml* ncurses-devel libmcrypt* libtool-ltdl-devel* make cmake pcre pcre-devel openssl openssl-devel jemalloc-devel tlc libtool bash-completion

3, Modify the hostname and add it to host
hostnamectl set-hostname xiaoming
IP hostname

4, oracle Dependent package installation
yum -y install binutils compat-libstdc+±33 elfutils-libelf-devel elfutils-libelf-devel-static elfutils-libelf-devel ksh libaio libaio-devel numactl-devel sysstat unixODBC unixODBC-devel pcre-devel

5, Add group user
groupadd oinstall
groupadd dba
useradd -g oinstall -G dba oracle

6, Modify the kernel parameters according to the official website
fs.file-max = 6815744
fs.aio-max-nr = 1048576
kernel.shmall = 2097152
kernel.shmmax = 2147483648
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

7, Modify user restrictions
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240

8, Create installation directory and permissions
mkdir -p /opt/oracle/product/11.2.0
mkdir /opt/oracle/oradata
mkdir /opt/oracle/inventory
mkdir /opt/oracle/fast_recovery_area
chown -R oracle:oinstall /opt/oracle
chmod -R 775 /opt/oracle

9, decompression oracle Installation package
unzip linux.x64_11gR2_database_1of2.zip && unzip linux.x64_11gR2_database_2of2.zip

10, Configure environment variables （ Use oracle The user action ）
ORACLE_BASE=/opt/oracle
ORACLE_HOME=$ORACL{E}_{B}ASE/product/11.2.0ORACL{E}_{S}ID=orclPATH=$PATH:$ORACLE_HOME/bin
export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK

11, edit oracle The configuration file
/database/response/db_install.rsp
oracle.install.option=INSTALL_DB_SWONLY
ORACLE_HOSTNAME=xiaoming
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/opt/oracle/inventory
SELECTED_LANGUAGES=en,zh_CN
ORACLE_HOME=/opt/oracle/product/11.2.0
ORACLE_BASE=/opt/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.isCustomInstall=false
oracle.install.db.DBA_GROUP=dba
oracle.install.db.OPER_GROUP=dba
DECLINE_SECURITY_UPDATES=true

12,oracle install （ Use oracle The user action ）
./runInstaller -silent -ignorePrereq -ignoreSysPrereqs -responseFile /opt/software/database/response/db_install.rsp
The appearance indicates success
To execute the configuration scripts:
1. Open a terminal window
2. Log in as “root”
3. Run the scripts
4. Return to this window and hit “Enter” key to continue
Successfully Setup Software.

13, Execute the required script
source /opt/oracle/inventory/orainstRoot.sh
source /opt/oracle/product/11.2.0/root.sh

14,oracle Configured to monitor
netca -silent -responseFile /opt/software/database/response/netca.rsp
The appearance indicates success
Oracle Net Services configuration successful. The exit code is 0

15, Check whether the port is listening normally
Netstat -luntp | grep 1521

16, To configure oracle User instance
[GENERAL]
RESPONSEFILE_VERSION = “11.2.0”
OPERATION_TYPE = “createDatabase”
[CREATEDATABASE]
GDBNAME = “orcl”
SID = “orcl”
TEMPLATENAME = “General_Purpose.dbc”
SYSPASSWORD = “oracle”
SYSTEMPASSWORD = “oracle”
SYSMANPASSWORD = “oracle”
DBSNMPPASSWORD = “oracle”
DATAFILEDESTINATION =/opt/oracle/oradata
RECOVERYAREADESTINATION=/opt/oracle/fast_recovery_area
CHARACTERSET = “ZHS16GBK”
TOTALMEMORY = “1638”

17, Instance installation
dbca -silent -responseFile /opt/software/database/response/dbca.rsp

18, Modify listening profile ( The default is hostname )
vim $ORACLE_HOME/network/admin/listener.ora
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST =xiaoming)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

19, On off
lsnrctl stop
lsnrctl stop
Close instance
sqlplus / as sysdba
SQL> shutdow immediate;
Boot instance
sqlplus / as sysdba
SQL> startup;
Start listening
lsnrctl start
20, To configure local_listener Parameters
$ sqlplus / as sysdba
Configuration parameters
alter system set local_listener="(address = (protocol = tcp)(host = 172.16.10.173)(port = 1521))";
see

21, Start listening

Create a database file
CREATE TABLESPACE MyDataBase LOGGING DATAFILE ‘/opt/oracle/oradata/orcl/MyDataBase.dbf’ SIZE 100M AUTOEXTEND ON NEXT 32M MAXSIZE 500M EXTENT MANAGEMENT LOCAL;

Create a temporary database file
create temporary TABLESPACE MyDataBase_temp tempfile ‘/opt/oracle/oradata/orcl/MyDataBase_temp.dbf’ SIZE 100M AUTOEXTEND ON NEXT 32M MAXSIZE 500M EXTENT MANAGEMENT LOCAL;

Create a mapping relationship between the user and the above two files
CREATE USER xiaoming IDENTIFIED BY Admin123 DEFAULT TABLESPACE MyDataBase TEMPORARY TABLESPACE MyDataBase_temp;

Add user rights
grant connect,resource,dba to xiaoming;
grant create session to xiaoming;

Delete database
conn sys/dwh as sysdba;
drop tablespace MyDataBase including contents and datafiles;
drop tablespace MyDataBase_temp including contents and datafiles;

Delete user
drop user xiaoming cascade;

When you don’t know what to do, just settle down and study！
