1、参考文章
1）http://blog.csdn.net/u010257584/article/details/50902472
2）http://blog.csdn.net/yabingshi_tech/article/details/46801539
2、安装环境
1）系统要求
内存最好有2G以上。
硬盘要求：
安装目录可用空间需要大于6.5G以上。
/tmp目录空间最少1G
2）软件要求：
检查需要安装的RPM包是否都已安装：
rpm -q binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXext libXtst libX11 libXau libxcb libXi make sysstat
根据上面结果安装所需的RPM包：
yum install xxx1 xxx2 xx3
确认是否安装上：
rpm -q binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXext libXtst libX11 libXau libxcb libXi make sysstat
3、创建用户
groupadd oinstall
groupadd oper
groupadd dba
useradd -g oinstall -G dba,oper oracle
//修改密码
passwd oracle
4、修改系统参数
vi /etc/sysctl.conf
添加：
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
运行sysctl -p应用以上参数
/sbin/sysctl -p
5、修改用户Limits
vi /etc/security/limits.conf
新增如下内容：
oracle soft nofile 65536
oracle hard nofile 65536
oracle soft nproc 16384
oracle hard nproc 16384
oracle stack nproc 10240
oracle stack nproc 10240
6、创建相关目录
mkdir -p /u01/app/oracle/product/12c/db_1
mkdir -p /u01/app/oracle/oradata
mkdir -p /u01/app/oracle/flash_recovery_area
mkdir -p /u01/app/oracle/archlog
chown -R oracle:oinstall /u01
7、配置环境变量
su - oracle
vi .bash_profile
添加如下内容：
# Oracle Settings
COLUMNS=132; export COLUMNS
LINES=47; export LINES
EDITOR=vi; export EDITOR
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/12c/db_1; export ORACLE_HOME
ORACLE_SID=orcl; export ORACLE_SID
SHLIB_PATH=$LD_LIBRARY_PATH;export SHLIB_PATH
NLS_LANG=American_America.zhs16gbk;export NLS_LANG
ORA_NLS10=$ORACLE_HOME/nls/data;export ORA_NLS10
TNS_ADMIN=$ORACLE_HOME/network/admin;export TNS_ADMIN
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$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
alias glance=/opt/perf/bin/glance:x
alias gohome='cd /u01/app/oracle/product/10.2.0'
alias cdb='cd /u01/app/oracle/admin/orcl/bdump'
alias cdu='cd /u01/app/oracle/admin/orcl/udump'
修改完用：source .bash_profile生效。
8、修改/etc/hosts
vi /etc/hosts
添加:
xxx.xxx.xxx.xxx your_host_name
9、上传文件
将安装包上传到/home/oracle目录下并解压，我安装的版本是：oracle-12.1.0.2-linux-x86_64.zip。
解压命令：
unzip -d orainstall oracle-12.1.0.2-linux-x86_64.zip
10、 安装oracle - 新建静默安装的应答文件
su - oracle
vi 12102db_install.rsp

11、静默安装软件
chmod 777 /home/oracle/orainstall/runInstaller
chmod 777 /home/oracle/orainstall/install/.oui
chmod 777 /home/oracle/orainstall/install/unzip
su - oracle
cd /home/oracle/orainstall
./runInstaller -silent -ignorePrereq -responseFile /home/oracle/12102db_install.rsp
如果提示不能访问临时目录，执行如下命令后，再重新执行runInstaller。
chmod 777 /tmp/CVU_12.1.0.2.0_oracle/*
执行完成安装命令后会立即返回，可以使用tail -f 安装日志，查看安装进度，安装完成的话会让执行两个命令：
使用root执行：
sh /u01/app/oraInventory/orainstRoot.sh
sh /u01/app/oracle/product/12c/db_1/root.sh
如果想重新安装：
rm -rf /u01/app/oraInventory
cd $ORACLE_HOME
rm *
12、建库
建响应文件：
vi /home/oracle/dbca.rsp
内容：
[GENERAL]
RESPONSEFILE_VERSION = "12.1.2.0"
OPERATION_TYPE = "createDatabase"
[CREATEDATABASE]
GDBNAME = "orcl"

TEMPLATENAME = "New_Database.dbt"
SYSPASSWORD = "orcl"
SYSTEMPASSWORD = "orcl"
SYSMANPASSWORD = "orcl"
DBSNMPPASSWORD = "orcl"
DATAFILEDESTINATION ="/u01/app/oracle/oradata"
STORAGETYPE=FS
CHARACTERSET = "ZHS16GBK"
DATABASETYPE = "MULTIPURPOSE"
AUTOMATICMEMORYMANAGEMENT = "FALSE"
执行：
dbca -silent -responseFile /home/oracle/dbca.rsp
export ORACLE_SID=orcl
sqlplus / as sysdba
进入sqlplus后执行，结果应显示OPEN。
select status from v$instance;
13、配监听

执行：
netca -silent -responseFile /home/oracle/12102_netca.rsp
14、设置开机启动
执行：
/u01/app/oracle/product/12c/db_1/bin/dbstart
假如执行/u01/app/oracle/product/12c/db_1/bin/dbstart报错：
ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener
Usage: /u01/app/oracle/oracle/product/10.2.0/db_1/bin/dbstart ORACLE_HOME
修改dbstart文件，将
ORACLE_HOME_LISTNER=$1
修改为
ORACLE_HOME_LISTNER=$ORACLE_HOME
修改/etc/oratab：
添加：
orcl:/u01/app/oracle/product/12c/db_1:Y
修改/etc/rc.d/rc.local
添加一行：
su oracle -lc /u01/app/oracle/product/12c/db_1/bin/dbstart
/u01/app/oracle/product/12c/dbhome_1为oracle的安装目录，要根据实际情况进行修改。
vim /etc/oratab
将
orcl:/u01/app/oracle/product/12c/db_1:Y
中的“N”改为“Y”
15、重启
使用plsql连接确认是否能连接成功，sys账号密码orcl
