Installation notes for CentOS x6.4 Oracle 12c

1. Preface

Oracle released the latest 12c database on the 27 th of last week.

This document records the installation process of Oracle 12c.

Note: It is widely recognized that the first minor version (such as 10g R1 and 11g R1) of the Oracle major version is a public beta version and does not meet commercial conditions for the production system. It seems that Oracle saves a lot of test costs.

Note that Oracle is only available in 64-bit versions and does not support 32-bit versions. It seems that Oracle has intentionally abandoned the development of the 32-bit version.

The installation environment in this article is CentOS 6.4 x86_64. As follows:

[Root @ CentOS-222-Oracle12 ~] # Uname-

Note: For some rpms, 32-bit and 64-bit versions must be installed simultaneously.

Here, the yum local source is used for installation. The process is as follows:

Create local source

Mkdir bak

Mv *. repo./bak

Vi/etc/yum. repos. d/local. repo

Modify the file content as follows:

[Local]

Name = local

Baseurl = file: // media/CentOS_6.4_Final

Enabled = 1

Gpgcheck = 0

Modify yum configuration. By default, both 32-bit and 64-bit rpm are installed.

Echo 'multilib _ policy = all'>/etc/yum. conf

Install the rpm package required for Oracle 12c

Yum install binutils compat-libcap1 compat-libstdc ++-33 gcc-c ++ glibc-devel ksh libgcc libstdc ++-devel libaio-devel libXext unzip libxlib11 xau libxcb libXi make sysstat

2. Configure OS 2.2.1. create relevant users and user groups

/Usr/sbin/groupadd oinstall

/Usr/sbin/groupadd dba

/Usr/sbin/useradd-g oinstall-G dba oracle

2.2.2. Modify the password of an oracle user

This step is not required

Passwd oracle

2.2.3. Back up and modify system parameters

Cp/etc/sysctl. conf/etc/sysctl. conf. bak

Vi/etc/sysctl. conf

Fs. aio-max-nr = 1048576

Fs. file-max = 6815744

Kernel. shmall = 2097152

Kernel. shmmax = 536870912

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 = 1048586

View the id of an oracle user group

More/etc/passwd

Oracle: x: 501: 501:/home/oracle:/bin/bash

Modify large memory limit

Echo 501>/proc/sys/vm/hugetlb_shm_group

Vi/etc/sysctl. conf

Vm. hugetlb_shm_group = 501

Modify Limits

Vi/etc/security/limits. conf

Add the following content:

Oracle soft nofile 65536

Oracle hard nofile 65536

Oracle soft nproc 16384

Hard nproc 16384

Nproc 10240

Nproc 10240

2.2.4. Create related directories

Mkdir-p/u01/app/

Chown-R oracle: oinstall/u01/app/

Chmod-R 775/u01/app/

2.2.5. Configure the network

Configure hosts

Hostname

CentOS-222-Oracle12

Vi/etc/hosts

127.0.0.1 CentOS-222-Oracle12

Oracle further discards the IP concept and replaces it with a domain name.

2.2.6. Configure Environment Variables

Su-oracle

Echo $ SHELL

/Bin/bash

Cd ~

Vi. bash_proFile

TMP =/tmp

TMPDIR =/tmp

Export TMP TMPDIR

3. Install Oracle

Then you can install Oracle.

Mounting oracle to install iso

Here, iso is self-made and can be decompressed directly using the official zip package.

If you need to customize iso, contact feiq 10.10.129.154.

Mount-t iso9660-o loop/mnt/hgfs/D/linuxamd64_12c_database.iso/home/oracle/mnt_iso/oracle_12c

Start Oracle Installation

Xhost +

Cd ~

Sh/home/oracle/mnt_iso/oracle_12c/linuxamd64_12c_database/database/runInstaller

It will be related to the graphic interface later. It is not much different from the old version and will not be introduced.

Note that the default option does not allow you to configure parameters such as pga sga. Select Advanced Option.

4. Subsequent work after installation 4. 1. Configure Environment Variables

Cd ~

Vi. bash_proFile

########## For Oracle ##########

ORACLE_BASE =/u01/app/oracle

Export ORACLE_BASE

ORACLE_HOME = $ ORACLE_BASE/product/12.1.0/dbhome_1

Export ORACLE_HOME

ORACLE_SID = orcl

Export ORACLE_SID

PATH = $ PATH:.: $ ORACLE_HOME/bin

Export PATH

5. Others

Some configuration options are simplified during the installation of Oracle 12c, but there is no essential change in the old version. The OUI is used as the installation interface. For those with installation experience, the installation difficulty is almost 0.
