Oracle12c for CentOs6.5安装

1.      检查软硬件要求

a.      物理内存

[root@ora12c ~]# grep MemTotal/proc/meminfo

MemTotal:        1907580 kB

b.      Swap配置

[root@ora12c ~]# grep SwapTotal/proc/meminfo

SwapTotal:       4194296 kB

c.       Tmp可用空间

[root@ora12c ~]# df -h /tmp

Filesystem      Size Used Avail Use% Mounted on

/dev/sda3        36G  11G   24G  31% /

d.      剩余磁盘空间

[root@ora12c ~]# df -h

Filesystem      Size Used Avail Use% Mounted on

/dev/sda3        36G  11G   24G  31% /

tmpfs           932M   72K 932M   1% /dev/shm

/dev/sda1        97M  34M   59M  37% /boot

/dev/sr0        4.2G 4.2G     0 100% /mnt/cdrom

e.      剩余磁内存和swap大小

[root@ora12c ~]# free

            total       used       free    shared    buffers     cached

Mem:      1907580    1786076     121504          0     20664    1521880

-/+ buffers/cache:     243532   1664048

Swap:     4194296          0    4194296

f.        操作系统检查(12c只能安装在64位系统)

[root@ora12c ~]# uname -a

Linux ora12c 2.6.32-431.el6.x86_64 #1 SMPFri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

2.      最小存储要求

a.      磁盘需求

Enterprise Edition

6.4 GB

b.      Tmp需求

1GB

3.      最小内存要求

Ram

swap

Between 1GB and 2GB

1.5 times sizes of RAM

Between 2GB and 16GB

Equal to the size of RAM

More than 16 GB

16 GB

4.      软件包安装

[root@ora12c ~]# yum -y install binutils compat-libcap1compat-libstdc++-33 compat-libstdc++-33.i686 gcc gcc-c++ glibc glibc.i686glibc-devel glibc-devel.i686 ksh libgcc libgcc.i686 libstdc++ libstdc++.i686libstdc++-devel libstdc++-devel.i686 libaio libaio.i686 libaio-devellibaio-devel.i686 ibXext ibXext.i686 libX11 libX11.i686 libxcb libxcb.i686libXi libXi.i686 make sysstat

5.      安装Linux pam(待定)

6.      创建操作系统组合用户

[root@ora12c ~]# groupadd oinstall

[root@ora12c ~]# groupadd dba

[root@ora12c ~]# grep dba /etc/group

 [root@ora12c ~]# grep oinstall /etc/group

 [root@ora12c ~]# id oracle

id: oracle: No such user

[root@ora12c ~]# useradd -g oinstall -G dbaoracle

[root@ora12c ~]# passwd oracle

7.      配置内核参数

[root@ora12c ~]# vim /etc/sysctl.conf

kernel.shmall = 4294967296

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

"/etc/sysctl.conf" 51L, 1458Cwritten

# 使内核参数生效

[root@ora12c ~]# sysctl –p

8.      配置资源限制

[root@ora12c ~]# vi/etc/security/limits.conf       

oracle soft  nproc   2047

oracle hard  nproc   16384

oracle soft  nofile  1024

oracle hard  nofile  65536

oracle soft  stack   10240

oracle hard  stack   32768

9.      创建目录

[root@ora12c ~]# mkdir -p/u01/app/oracle/product/12.1.0/db_1

[root@ora12c ~]# chown -R oracle.oinstall/u01

[root@ora12c ~]# chmod -R 775 /u01/app/

10.  配置环境变量

[oracle@ora12c ~]$ cat .bash_profile

# .bash_profile

 

# Get the aliases and functions

if [ -f ~/.bashrc ]; then

       . ~/.bashrc

fi

 

# User specific environment and startupprograms

 

PATH=$PATH:$HOME/bin

 

export PATH

 

########## for Oracle ##########

 

ORACLE_BASE=/u01/app/oracle

 

export ORACLE_BASE

 

ORACLE_HOME=/u01/app/oracle/product/12.1.0/db_1

 

export ORACLE_HOME

 

ORACLE_SID=ora12c

 

export ORACLE_SID

 

PATH=$PATH:.:$ORACLE_HOME/bin

 

export PATH
