这篇文章主要介绍了Linux 7上如何安装Oracle 12c，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
一、下载软件
1、Oralce linux 7
2、Oracle 12c
二、安装Oracle linux 并进行设置
1、安装Oracle Linux
2、设置主机名
/etc/hosts
/etc/hostname
3、设置SELINUX
/etc/selinux/config
SELINUX=permissive
>setenforce Permissive
4、关闭防护墙
>stemctl stop firewalld
>systemctl disable firewalld
5、yum库配置
mount /dev/cdrom /mnt
mount /dev/ddvd /mnt[可以一试]
/etc/yum.repos.d
>cp public-yum-ol7.repo public-yum-ol7.repobak
[ol7_u0_base]
name=Oracle Linux $releasever GA installation media copy ($basearch)
baseurl=file:///mnt
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1
yum clean
yum list
yum update -y
yum install oracle-database-server-12cR2-preinstall -y
yum groupinstall 'X Window System' -y
5、手工设置
如果没有yum install oracle-database-server-12cR2-preinstall -y 需要如下设置
(1) "/etc/sysctl.conf" file, or in a file called "/etc/sysctl.d/98-oracle.conf".
fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104
kernel.panic_on_oops = 1
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.conf.all.rp_filter = 2
net.ipv4.conf.default.rp_filter = 2
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500
/sbin/sysctl -p
(2) Add the following lines to a file called "/etc/security/limits.d/oracle-database-server-12cR2-preinstall.conf" file
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft nproc 16384
oracle hard nproc 16384
oracle soft stack 10240
oracle hard stack 32768
oracle hard memlock 134217728
oracle soft memlock 134217728
(3) rpm包
# OL6 and OL7 (RHEL6 and RHEL7)

yum install glibc-devel.i686 -y
yum install ksh -y
yum install libaio -y
yum install libaio.i686 -y
yum install libaio-devel -y
yum install libaio-devel.i686 -y
yum install libX11 -y
yum install libX11.i686 -y
yum install libXau -y
yum install libXau.i686 -y
yum install libXi -y
yum install libXi.i686 -y

yum install libxcb -y
yum install libxcb.i686 -y
yum install make -y
yum install nfs-utils -y
yum install net-tools -y
yum install smartmontools -y
yum install sysstat -y
yum install unixODBC -y
yum install unixODBC-devel -y
# Required for 12.1, not listed for 12.2
yum install gcc -y
yum install gcc-c++ -y
yum install libXext -y
yum install libXext.i686 -y
yum install zlib-devel -y
yum install zlib-devel.i686 -y
# OL6 only (RHEL6 only)
yum install e2fsprogs -y
yum install e2fsprogs-libs -y
yum install libs -y
yum install libxcb.i686 -y
yum install libxcb -y
(4)建立用户和组
groupadd -g 54321 oinstall
groupadd -g 54322 dba
groupadd -g 54323 oper
#groupadd -g 54324 backupdba
#groupadd -g 54325 dgdba
#groupadd -g 54326 kmdba
#groupadd -g 54327 asmdba
#groupadd -g 54328 asmoper
#groupadd -g 54329 asmadmin
#groupadd -g 54330 racdba
useradd -g oinstall -G dba,oper oracle
usermod -g oinstall -G dba,oper oracle
passwd oracle
6、建立目录
mkdir -p /u01/app/oracle/product/12.2.0.1/db_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01
7、配置oracle环境变量
.bash_profile
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=ole
export ORACLE_UNQNAME=orcl
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.2.0.1/db_1
export ORACLE_SID=orcl
export PATH=/usr/sbin:/usr/local/bin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
DISPLAY=<machine-name>:0.0; export DISPLAY
