一、准备
1.1 安装环境
系统要求
内存 > 2G
安装目录空间 > 6.5G
/tmp目录空间 > 1G
操作系统
cat /etc/redhat-release
用rpm命令确认软件是否已安装
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
提示未安装的软件用yum安装
yum install -y compat-libcap1 compat-libstdc++-33 libaio-devel libXext libXtst libX11 libXau libxcb libXi sysstat
确认安装
1.2 创建用户
groupadd oinstall
groupadd oper
groupadd dba
useradd -g oinstall -G dba,oper oracle
# 修改密码
passwd oracle
1.3 修改系统参数
vi /etc/sysctl.conf
追加：
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096

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
1.6 配置环境变量
su - oracle
vi .bash_profile
追加：

alias cdb='cd /u01/app/oracle/admin/orcl/bdump'
alias cdu='cd /u01/app/oracle/admin/orcl/udump'
使配置生效
source .bash_profile
1.7 修改/etc/hosts
vi /etc/hosts
添加:
xxx.xxx.xxx.xxx your_host_name
1.8 上传文件
unzip -d orainstall oracle-12.1.0.2-linux-x86_64.zip
二、安装oracle
2.1 新建静默安装的应答文件
su - oracle
vi 12102db_install.rsp
内容，注意hostname，和相关路径要与实际相符

2.2 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 $ORACLE_HOME
rm *
三、建库
3.1 建响应文件
vi /home/oracle/dbca.rsp
内容：
[GENERAL]
RESPONSEFILE_VERSION = "12.1.2.0"
OPERATION_TYPE = "createDatabase"
[CREATEDATABASE]
GDBNAME = "orcl"
SID = "orcl"
TEMPLATENAME = "New_Database.dbt"
SYSPASSWORD = "orcl"
SYSTEMPASSWORD = "orcl"
SYSMANPASSWORD = "orcl"
DBSNMPPASSWORD = "orcl"
DATAFILEDESTINATION ="/u01/app/oracle/oradata"
STORAGETYPE=FS
CHARACTERSET = "ZHS16GBK"
DATABASETYPE = "MULTIPURPOSE"
AUTOMATICMEMORYMANAGEMENT = "FALSE"
3.2 静默建库
dbca -silent -responseFile /home/oracle/dbca.rsp
export ORACLE_SID=orcl
sqlplus / as sysdba
进入sqlplus后执行，结果应显示OPEN
select status from v$instance;
四、配监听
4.1 应答文件

# Name : SHOW_GUI
# Datatype : Boolean
# Description: This variable controls appearance/suppression of the NetCA GUI,
# Pre-req : N/A
# Default : TRUE
# Note:
# This must be set to false in order to run NetCA in silent mode.
# This is a substitute of "/silent" flag in the NetCA command line.
# The command line flag has precedence over the one in this response file.
# This feature is present since 10.1.0.3.
#-------------------------------------------------------------------------------
#SHOW_GUI=false
#-------------------------------------------------------------------------------
# Name : LOG_FILE
# Datatype : String
# Description: If present, NetCA will log output to this file in addition to the
# standard out.
# Pre-req : N/A
# Default : NONE
# Note:
# This is a substitute of "/log" in the NetCA command line.
# The command line argument has precedence over the one in this response file.
# This feature is present since 10.1.0.3.
#-------------------------------------------------------------------------------

4.2 静默配监听
netca -silent -responseFile /home/oracle/12102_netca.rsp
五、开机启动
5.1 设置开机启动
/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
ddd
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
1
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”
5.2 重启
重启后，plsql连接数据库，sys/orcl
