Oracle 12c：Oracle12c怎么安装

Oracle12c：Oracle12c怎么安装，下面是安装步骤：

1.软件版本

数据库软件：Oracle release 12.1

操作系统：Oracle Linux 5.6 64bit

2.安装步骤

修改系统参数

[root@oracle12c dev]# vi /etc/sysctl.conf

kernel.shmall = 4294967296

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 2075004928

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

系统参数生成

[root@oracle12c dev]# /sbin/sysctl -p

net.ipv4.ip_forward = 0

net.ipv4.conf.default.rp_filter = 2

net.ipv4.conf.default.accept_source_route = 0

kernel.sysrq = 0

kernel.core_uses_pid = 1

net.ipv4.tcp_syncookies = 1

kernel.msgmnb = 65536

kernel.msgmax = 65536

kernel.shmmax = 68719476736

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

硬件相关的限制设置

[root@oracle12c ~]# vi /etc/security/limits.conf

添加：

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

建立用户组和用户

[root@oracle12c dev]# groupadd -g 1000 oinstall

[root@oracle12c dev]# groupadd -g 1200 dba

[root@oracle12c dev]# useradd -u 1100 -g oinstall -G dba oracle

[root@oracle12c dev]# passwd oracle

Changing password for user oracle.

New UNIX password:

BAD PASSWORD: it is based on a dictionary word

Retype new UNIX password:

passwd: all authentication tokens updated successfully.

建立目录

[root@oracle12c dev]# mkdir -p /u01/app/

[root@oracle12c dev]# chown -R oracle:oinstall /u01/app/

[root@oracle12c dev]# chmod -R 775 /u01/app/

设置oracle用户环境变量

[root@oracle12c dev]# su - oracle

[oracle@oracle12c ~]$ vi .bash_profile

# Oracle Settings

TMP=/tmp; export TMP

TMPDIR=$TMP; export TMPDIR

ORACLE_BASE=/u01/app; export ORACLE_BASE

DB_HOME=$ORACLE_BASE/product/12.1/db_1; export DB_HOME

ORACLE_HOME=$DB_HOME; export ORACLE_HOME

ORACLE_SID=jessica; export ORACLE_SID

ORACLE_TERM=xterm; export ORACLE_TERM

BASE_PATH=/usr/sbin:$PATH; export BASE_PATH

PATH=$ORACLE_HOME/bin:$BASE_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

安装Oracle软件

解压缩完安装介质后，有database目录

[root@oracle12c ~]# mkdir /u01/oraInventory

[root@oracle12c ~]# chown -R oracle:oinstall /u01/oraInventory

[root@oracle12c u01]# chown -R oracle:oinstall database

[root@oracle12c u01]# ll

total 8

drwxrwxr-x 2 oracle oinstall 4096 Jun 29 23:20 app

drwxr-xr-x 7 oracle oinstall 4096 Jun 10 20:14 database

[oracle@oracle12c ~]$ export DISPLAY=192.168.1.55:0

[oracle@oracle12c ~]$ cd /u01/database

[oracle@oracle12c database]$ ls

install response rpm runInstaller sshsetup stage welcome.html

[oracle@oracle12c database]$ ./runInstaller

之后就会跳出窗口进行Oracle12c的安装，在安装过程中可以看到允许创建PDB(pluggable database)，这个是12c中的新特性。
