Oracle 11g installation on Linux

Oracle 11g installation on Linux

1. Create the required users and groups

Vim mk_user.sh

GROUPADD-G 501 Oinstall
GROUPADD-G 502 DBA
GROUPADD-G 503 Oper
Useradd-u 501-g oinstall-g Dba,oper Oracle

SH mk_user.sh

2. Create the desired directory
   Vim mk_dir.sh

Mkdir-p/u01/app/orainventory
Chmod-r 775/u01/app/orainventory
Mkdir-p/u01/app/oracle
Mkdir/u01/app/oracle/cfgtoollogs
Chown-r oracle:oinstall/u01
Chmod-r 775/u01/app/oracle
Mkdir-p/u01/app/oracle/product/11.2.0/dbhome_1
Chown-r Oracle:oinstall/u01/app/oracle/product/11.2.0/dbhome_1
Chmod-r 775/u01/app/oracle/product/11.2.0/dbhome_1

SH mk_dir.sh
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

3. Install the required installation package
   A. Attach the disc to the/MNT
   Mount/dev/cdrom/mnt
   B. Back up the original repo file and create a new repo file
   Mkdir/etc/yum.repo.d/bak
   Mv/etc/yum.repo.d/*.repo/etc/yum.repo.d/bak
   Vim/etc/yum.repo.d/cdrom.repo

[CDROM]
Name=cdrom
Baseurl=file:///mnt
Enabled=1
Gpgcheck=0
Multilib_policy=all

Save exit

Clean up the Yum cache and rebuild the new cache:
Yum Clean All
Yum Makecache

C. Install the required packages
Yum install binutils COMPAT-LIBCAPL compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc-2.5-24 Glibc-common glibc-devel glibc-headers ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel make-3.81 sysstat-7.0.2

Redhat need to be installed separately
Compat-libstdc++-33 and Pdksh
Pdksh is an old bag, the new Oracle uses the KSH package, but Oracle's check mechanism does not remove this check, so when the interface to install Oracle, there will be alarm information, we can ignore it, and then see if Ksh is installed, If you install Ksh without installation, you can use Ksh.

4. Modify the Hosts file
   Vim/etc/hosts
   Adding IP and host names to the Hosts file

5. Modify/etc/sysctl.conf

Vim/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 = 1048576

Sysctl–p make current changes effective

6. Configure resource limits for Oracle users

Vim/etc/security/limits.conf

Oracle Soft Nproc 2047
Oracle Hard Nproc 16384
Oracle Soft Nofile 1024
Oracle Hard Nofile 65536

7. Modify Profile File

Vim/etc/profile
Add the following content

if [$USER = "Oracle"] | | [$USER = "Grid"]; Then
if [$SHELL = "/bin/ksh"]; Then
Ulimit-p 16384
Ulimit-n 65536
Else
Ulimit-u 16384-n 65536
Fi
Umask 022
Fi

8. Modify user environment variables (operate under Oracle user)
   Vim. Bash_profile

#!/bin/bash
tmp=/tmp; Export TMP
Tmpdir= $TMP; Export TMPDIR
Oracle_base=/u01/app/oracle; Export Oracle_base
Oracle_home= $ORACLE _base/product/11.2.0/dbhome_1; Export Oracle_home
Oracle_sid=prod; Export Oracle_sid
Oracle_unqname=prod; Export Oracle_unqname
Oracle_term=xterm; Export Oracle_term
Path=/usr/sbin: $PATH; Export PATH
Path= $ORACLE _home/bin: $PATH; Export PATH
Ld_library_path= $ORACLE _home/lib:/lib:/usr/lib; Export Ld_library_path
Classpath= $ORACLE _home/jre: $ORACLE _home/jlib: $ORACLE _home/rdbms/jlib;
Export CLASSPATH

After you save the exit, execute the following command to make the above settings effective immediately:
Source/home/oracle/.bash_profile

9. Unpacking the installation package
   Unzip Linux.x64_11gR2_database_1of2.zip
   Unzip Linux.x64_11gR2_database_2of2.zip

10. Installation
    If the operating system is in Chinese, the installation will be garbled can be executed before the installation
    Export Lang=en_us. UTF-8
    Then execute the./runinstaller

    Redhat 7.4 will be reported during installation
    Error in invoking target ' agent NMHS ' of makefile '/u01/app/oracle/product/11.2.0/db_1/sysman/lib/ins_emagent.mk '.

Solve:
VI $ORACLE _HOME/SYSMAN/LIB/INS_EMAGENT.MK

Find the following line
$ (MK_EMAGENT_NMECTL)

Change this line to:
$ (MK_EMAGENT_NMECTL)-lnnz11

The first one is the letter L, and the last two is the number 1.
