Installing Oracle11g under Linux

1、 Environmental preparation 
 operating system ：CentOS7 64 position 
Oracle11g Compressed packages and various dependent packages 
2、 Dependent package detection 
rpm -q binutils compat-libstdc++-33 elfutils-libelf 		elfutils-libelf-devel gcc gcc-c++ glibc glibc-common glibc-devel 	glibc-headers kernel-headers ksh libaio libaio-devel libgcc libgomp 	libstdc++ libstdc++-devel make numactl-devel sysstat unixODBC 	unixODBC-devel
3、 Install missing dependency packages 
 Carry out orders ：yum -y install  Dependent package name  #  In case of networking 
  rpm -ivh  Dependent package name  #  When the Internet is not available 
4、 Create directory user, membership group and permission configuration 
# Create group 
groupadd oinstall
groupadd dba
# Create user 
useradd -g oinstall -G dba oracle
# Set the password 
passwd oracle 
# Create installation directory 
mkdir -p /usr/local/oracle/product/11.2.0/db_1
mkdir -p /usr/local/oracle/oradata
mkdir -p /usr/local/oracle/inventory
mkdir -p /usr/local/oracle/fast_recovery_area
# to grant authorization 
chown -R oracle.oinstall  /usr/local//oracle
chmod -R 755 /usr/local/oracle
5、 Server configuration modification 
# Modify hostname 
vim /etc/hosts
# stay host Add... To the file 
127.0.0.1 oracledb

# to open up 1521 port 
firewall-cmd --zone=public --add-port=1521/tcp --permanent 
firewall-cmd --reload
firewall-cmd --list-ports --zone=public

# close selinux
vim /etc/sysconfig/selinux
# modify selinux The value in 
SELINUX=disabled
# Execute the command to make the modification effective ：
setenforce 0

# Modify kernel parameters 
vim /etc/sysctl.conf
# Add the following 
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 1073741824
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
# Execute the command to make the modification effective 
sysctl -p
           
# Modify user restriction file 
vim /etc/security/limits.conf
# Add the following 
oracle    soft    nproc    2047
oracle    hard    nproc    16384
oracle    soft    nofile    1024
oracle    hard    nofile    65536
oracle    soft    stack    10240
# modify /etc/pam.d/login file 
vim /etc/pam.d/login
# Add the following 
session required  /lib64/security/pam_limits.so
session required   pam_limits.so

# To configure oracle The user's environment variables （ Use oracle user ）
su - oracle
vim  ~/.bash_profile
# add to 
ORACLE_BASE=/usr/local/oracle
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
ORACLE_SID=orcl
PATH=$PATH:$ORACLE_HOME/bin
export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH
# Execute the command to make the modification effective 
.  ~/.bash_profile
6、 Start installation 
# Switch to root user 
su root
cd /tmp/
mkdir oracle
cd oracle
# decompression 
unzip linux.x64_11gR2_database_1of2.zip
unzip linux.x64_11gR2_database_2of2.zip 

# After decompression 
# Edit silent install response file 
cd /tmp/oracle/database/response/
vim db_install.rsp
# Modify the following 
oracle.install.option=INSTALL_DB_SWONLY
ORACLE_HOSTNAME=oracle         
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/usr/local/oracle/inventory

# Start installing software 
chown -R oracle:oinstall  /tmp/oracle/
su - oracle
cd /tmp/oracle/database/
./runInstaller -silent -responseFile /tmp/oracle/database/response/db_install.rsp 	-ignorePrereq

# Switch back to after installation root User execution script 
/usr/local/oracle/inventory/orainstRoot.sh
/usr/local/oracle/product/11.2.0/db_1/root.sh

# Configured to monitor 
su - oracle
netca  /silent  /responseFile /tmp/oracle/database/response/netca.rsp

# see 1521 Whether the port is monitored 
netstat -tnulp | grep 1521

# Listen for startup and shutdown commands 
lsnrctl start 
lsnrctl stop

# Building database 
cd /tmp/oracle/database/response/
cp dbca.rsp dbca.rsp.bak
vim dbca.rsp
# Modify the parameters 
GDBNAME= "orcl"

SYSPASSWORD= "oracle"
SYSTEMPASSWORD= "oracle"
SYSMANPASSWORD= "oracle"
DBSNMPPASSWORD= "oracle"
DATAFILEDESTINATION=/usr/local/oracle/oradata
RECOVERYAREADESTINATION=/usr/local/oracle/fast_recovery_area
CHARACTERSET= "ZHS16GBK"
# Physical memory 
TOTALMEMORY= "1638"
# Carry out orders 
dbca  -silent  -responseFile  /tmp/oracle/database/response/dbca.rsp

# Test for Serviceability 
sqlplus / as sysdba

7、 Create a tablespace user and authorize 
2、 Create tablespace ;
create temporary tablespace MDGHPS_TEMP tempfile '/usr/local/MDGHPS_TEMP.dbf' size 100m reuse autoextend on next 20m maxsize unlimited;
create tablespace MDGHPS datafile '/usr/local/MDGHPS.dbf' size 100M reuse autoextend on next 40M maxsize unlimited default storage(initial 128k next 128k minextents 2 maxextents unlimited);
3、 Create user ;
create user MDGHPS identified by MDGHPS default tablespace MDGHPS temporary tablespace MDGHPS_TEMP;
4、 Authorize users ;
grant connect,resource to demo;  
grant create any sequence to demo;  
grant create any table to demo;  
grant delete any table to demo;  
grant insert any table to demo;  
grant select any table to demo;  
grant unlimited tablespace to demo;  
grant execute any procedure to demo;  
grant update any table to demo;  
grant create any view to demo;  
-- dba jurisdiction 
grant connect, resource, dba to demo;	
5、 Switching users ;
MDGHPS/MDGHPS;
6、 Import the full database script MDGHPS.sql;
@/usr/MDGHPS.sql;
commit;
