環(huán)境準(zhǔn)備：
VMware+CentOS，jdk
一、校驗(yàn)系統(tǒng)磁盤大小
1.命令 df -h
保證可用磁盤大小15GB（包括oracle安裝時(shí)需要空間7.5GB + oracle安裝zip包接近3G+安裝包解壓文件3G）
如果磁盤不滿足，安裝會(huì)失敗，需要擴(kuò)容！
二、安裝準(zhǔn)備
1.創(chuàng)建運(yùn)行oracle數(shù)據(jù)庫(kù)的系統(tǒng)用戶和用戶組
groupadd oinstall groupadd dba useradd -g oinstall -g dba -m oracle
passwd oracle #不用管提示，連續(xù)輸入兩次密碼就可成功
2.創(chuàng)建oracle數(shù)據(jù)庫(kù)安裝目錄，并將目錄賦權(quán)給oracle用戶
mkdir -p /opt/oracle/database #oracle安裝包解壓的文件 mkdir -p /opt/oracle/product/oraInventory # mkdir -p /opt/oracle/product/12.2.0/db_1 #oracle安裝目錄 chown -R oracle:oinstall /opt/oracle #更改oracle目錄的屬主 chmod 755 -R /opt/oracle #更改oracle目錄的權(quán)限
3.安裝oracle數(shù)據(jù)庫(kù)依賴的軟件包
3.1.安裝
yum -y install binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel gcc gcc-c++ libaio-devel libaio libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel pdksh numactl-devel glibc-headers
3.2.查看是否安裝成功
rpm -q \binutils \compat-libstdc++-33 \elfutils-libelf \elfutils-libelf-devel \expat \gcc \gcc-c++ \glibc \glibc-common \glibc-devel \glibc-headers \libaio \libaio-devel \libgcc \libstdc++ \libstdc++-devel \make \pdksh \sysstat \unixODBC \unixODBC-devel | grep "not installed"
4.關(guān)閉selinux，需要重啟生效（可以在最后安裝oracle之前再重啟） vim /etc/selinux/config
5.修改內(nèi)核參數(shù) vim /etc/sysctl.conf
添加如下內(nèi)容：
net.ipv4.icmp_echo_ignore_broadcasts = 1
net.ipv4.conf.all.rp_filter = 1
fs.file-max = 6815744
fs.aio-max-nr = 1048576
kernel.shmall = 2097152
kernel.shmmax = 2147483648
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= 1048576
sysctl -p #使配置生效
6.對(duì)oracle用戶設(shè)置限制，提高系統(tǒng)運(yùn)行性能
vim /etc/security/limits.conf
添加如下內(nèi)容：
oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536
7.配置用戶環(huán)境變量
vim /home/oracle/.bash_profile
添加如下內(nèi)容：
export ORACLE_BASE=/opt/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.2.0/db_1
export ORACLE_SID=orcl
export ORACLE_TERM=xterm
export PATH=$ORACLE_HOME/bin:/usr/sbin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export LANG=C
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
source /home/oracle/.bash_profile #使配置失效
8.解壓oracle安裝文件的壓縮包，在/opt/oracle/目錄下解壓
unzip 文件名（unzip不存在，可用命令進(jìn)行安裝： yum install unzip）加壓較慢，需要等會(huì)
9.配置應(yīng)答文件
vim /opt/oracle/database/response/db_install.rsp
10.配置oraInventory目錄位置
存放oracle軟件安裝的目錄信息，oracle的安裝和升級(jí)都需要用到這個(gè)目錄（最好放在ORACLE_BASE對(duì)應(yīng)的目錄下邊）
vim /etc/oraInst.loc
添加或修改成如下內(nèi)容：
inventory_loc=/opt/oracle/product/oraInventory
inst_group=oinstall
11.重啟CentOS，reboot
12.關(guān)閉防火墻，systemctl stop firewalld
三、靜默安裝Oracle12
1.已oracle用戶登陸linux系統(tǒng)
2.靜默安裝
/opt/oracle/database/runInstaller -silent -force -ignorePrereq -responseFile /opt/oracle/database/response/db_install.rsp
執(zhí)行過(guò)程需要等待幾分鐘。
可監(jiān)控日志:
tail -f /opt/oracle/product/oraInventory/logs/installActions2018-11-22_11-04-03AM.log
3.切換root用戶登陸
4.執(zhí)行兩個(gè)sh文件
4.1. sh /opt/oracle/product/oraInventory/orainstRoot.sh
如果目錄下沒(méi)有改腳本，可以新建一個(gè)，腳本內(nèi)容為：
# cat /oracle/oraInventory/orainstRoot.sh
#!/bin/sh
AWK=/bin/awk
CHMOD=/bin/chmod
CHGRP=/bin/chgrp
CP=/bin/cp
ECHO=/bin/echo
MKDIR=/bin/mkdir
RUID=`/usr/bin/id|$AWK -F ′ print$2 ′ |$AWK−F ′print$2′|$AWK−F '{print $2}'|$AWK -F '{print $1}'`
if [ ${RUID} != "root" ];then
$ECHO "This script must be executed as root"
exit 1
fi
if [ -d "/etc" ]; then
$CHMOD 755 /etc;
else
$MKDIR -p /etc;
fi
if [ -f "/oracle/oraInventory/oraInst.loc" ]; then
$CP /oracle/oraInventory/oraInst.loc /etc/oraInst.loc;
$CHMOD 644 /etc/oraInst.loc
else
INVPTR=/etc/oraInst.loc
INVLOC=/oracle/oraInventory
GRP=oinstall
PTRDIR="`dirname $INVPTR`";
# Create the software inventory location pointer file
if [ ! -d "$PTRDIR" ]; then
$MKDIR -p $PTRDIR;
fi
$ECHO "Creating the Oracle inventory pointer file ($INVPTR)";
$ECHO inventory_loc=$INVLOC > $INVPTR
$ECHO inst_group=$GRP >> $INVPTR
chmod 644 $INVPTR
# Create the inventory directory if it doesn't exist
if [ ! -d "$INVLOC" ];then
$ECHO "Creating the Oracle inventory directory ($INVLOC)";
$MKDIR -p $INVLOC;
fi
fi
$ECHO "Changing permissions of /oracle/oraInventory.
Adding read,write permissions for group.
Removing read,write,execute permissions for world.
";
$CHMOD -R g+rw,o-rwx /oracle/oraInventory;
if [ $? != 0 ]; then
$ECHO "OUI-35086:WARNING: chmod of /oracle/oraInventory
Adding read,write permissions for group.
,Removing read,write,execute permissions for world.
failed!";
fi
$ECHO "Changing groupname of /oracle/oraInventory to oinstall.";
$CHGRP -R oinstall /oracle/oraInventory;
if [ $? != 0 ]; then
$ECHO "OUI-10057:WARNING: chgrp of /oracle/oraInventory to oinstall failed!";
fi
$ECHO "The execution of the script is complete."
4.2. sh /opt/oracle/product/12.2.0/db_1/root.sh
5.切換oracle用戶登陸
6.安裝監(jiān)聽(tīng)
$ORACLE_HOME/bin/netca /silent /responseFile /opt/oracle/database/response/netca.rsp
7.啟動(dòng)監(jiān)聽(tīng)程序
lsnrctl start
8.查看監(jiān)聽(tīng)狀態(tài)
lsnrctl status
9.通過(guò)dbca創(chuàng)建數(shù)據(jù)庫(kù)
/opt/oracle/product/12.2.0/db_1/bin/dbca -silent -createDatabase -templateName General_Purpose.dbc -gdbname orcl -sid orcl -responseFile NO_VALUE -characterSet ZHS16GBK -memoryPercentage 30 -emConfiguration LOCAL
（刪除：dbca -silent -deleteDatabase -sourcedb orcl -sid orcl）
10.啟動(dòng)實(shí)例（創(chuàng)建完，一般會(huì)自動(dòng)啟動(dòng)）
sqlplus / as sysdba SQL> startup SQL> select instance_name,version from v$instance;
查看數(shù)據(jù)庫(kù)文件dbf
SQL> select name from v$datafile;
總結(jié)
