1.      檢查軟硬體要求

a.      實體記憶體

[[email protected] ~]# grep MemTotal/proc/meminfo

MemTotal:        1907580 kB

b.      Swap配置

[[email protected] ~]# grep SwapTotal/proc/meminfo

SwapTotal:       4194296 kB

c.       Tmp可用空間

[[email protected] ~]# df -h /tmp

Filesystem      Size Used Avail Use% Mounted on

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

d.      剩餘磁碟空間

[[email protected] ~]# 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.      剩餘磁記憶體和swap大小

[[email protected] ~]# free

            total       used       free    shared    buffers     cached

Mem:      1907580    1786076     121504          0     20664    1521880

-/+ buffers/cache:     243532   1664048

Swap:     4194296          0    4194296

f.        作業系統檢查(12c只能安裝在64位系統)

2.      最小儲存要求

a.      磁碟需求

b.      Tmp需求

1GB

3.      最小記憶體要求

4.      軟體包安裝

[[email protected] ~]# 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.      安裝Linux pam(待定)

6.      建立作業系統組合使用者

[[email protected] ~]# groupadd oinstall

[[email protected] ~]# groupadd dba

[[email protected] ~]# grep dba /etc/group

 [[email protected] ~]# grep oinstall /etc/group

 [[email protected] ~]# id oracle

id: oracle: No such user

[[email protected] ~]# useradd -g oinstall -G dbaoracle

[[email protected] ~]# passwd oracle

7.      配置核心引數

[[email protected] ~]# 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

# 使核心引數生效

[[email protected] ~]# sysctl –p

8.      配置資源限制

[[email protected] ~]# 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.      建立目錄

[[email protected] ~]# mkdir -p/u01/app/oracle/product/12.1.0/db_1

[[email protected] ~]# chown -R oracle.oinstall/u01

[[email protected] ~]# chmod -R 775 /u01/app/

10.  配置環境變數

[[email protected] ~]$ 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

11. 解壓縮安裝即可
