Installing Oracle 11g RAC in Oracle Linux 5.8

Chapter 1: configure the experiment environment

The experiment environment is implemented using virtual box virtual Machine Software. The steps for installing the operating system are ignored...

1.1 server operating system:

1.2. Oracle software version:

Oracle database	11.2.0.3
Oracle grid	11.2.0.3

1.3 virtual machine hardware configuration

Each virtual machine is allocated with 3 GB memory, 2 CPUs, two NICs, and 60 GB hard disks.

Chapter 2: Configure virtual hosts and prepare the environment

2.1-2.7 The two virtual machines must be configured the same (except for the host name and IP address, as configured in chapter 1 ).

The udev binding script comes from the oracle 11g rac tutorial of maclean liu.

2.1 disable selinux and iptables

Modify the/etc/selinux/config file and SELINUX = disables to disable SELINUX.

/Etc/init. d/iptables stop disable the Firewall Service.

Chkconfig-level 35 ipatables off disable service startup. '

2.2 modify the Host Name and hosts file

2.3 create related user groups

The CREATE Command is as follows:

Groupadd-g 5000 asmadmin

Groupadd-g 5001 asmdba

Groupadd-g 5002 asmoper

Groupadd-g 6000 oinstall

Groupadd-g 6001 dba

Groupadd-g 6002 running

Useradd-g oinstall-G asmadmin, asmdba, asmoper grid

Useradd-g oinstall-G dba, asmdba oracle

2.4 configure the yum source and install the software packages required by oracle

Vi edit the oinstall. repo file and enter the following content:

[Oracle-install]

Name = oracle-install

Baseurl = file: // media/disk/Server

Gpgcheck = 0

Enabled = 1

Run yum install oracle-validated and enter Y to install the tool.

2.5 modify user limit parameter files

Cat/etc/security/limits. conf: Check the parameters of the User restriction file. After yum install oracle-vildated is used, the oracle user parameters are automatically configured.

You only need to add the number of grid users to the file.

# Grid-Validated setting for nofile soft limit is 131072

Grid soft nofile 131072

# Grid-Validated setting for nofile hard limit is 131072

Grid hard nofile 131072

# Grid-Validated setting for nproc soft limit is 131072

Grid soft nproc 131072

# Grid-Validated setting for nproc hard limit is 131072

Grid hard nproc 131072

# Grid-Validated setting for core soft limit is unlimited

Grid soft core unlimited

# Grid-Validated setting for core hard limit is unlimited

Grid hard core unlimited

# Grid-Validated setting for memlock soft limit is 50000000

Grid soft memlock 50000000

# Grid-Validated setting for memlock hard limit is 50000000

Grid hard memlock 50000000

2.6 create the installation directory for the database and grid

Mkdir/u01

Mkdir/g01

Chown-R oracle: oinstall/u01

Chown-R grid: oinstall/g01

Passwd oracle

Passwd grid

2.7 disable the ntp service

[Root @ rac1] #/etc/init. d/ntpd status

Ntpd is stopped

[Root @ rac1] # chkconfig ntpd off

[Root @ rac1] # mv/etc/ntp. conf/etc/ntp. conf. original
