1 hosts主机配置
echo "neiwangip 主机名" >> /etc/hosts
2 配置英文环境变量
echo "export LANG=en_US" >> ~/.bash_profile
export NLS_LANG=SIMPLIFIED CHINESE_CHINA.ZHS16GBK
3 创建用户与目录
/usr/sbin/groupadd -g 60001 oinstall
/usr/sbin/groupadd -g 60002 dba
/usr/sbin/groupadd -g 60003 oper
useradd -u 61001 -g oinstall -G dba,oper oracle
id oracle
passwd oracle
mkdir /oracle
mkdir /oradata
mkdir -p /oracle/app/oracle/product/12.2.0/db_1
mkdir -p /oracle/app/oraInventory
chown -R oracle:oinstall /oracle
chown -R oracle:oinstall /oradata
chmod -R 775 /oracle
chmod -R 775 /oradata

5 修改操作系统相关参数
5.1 修改资源限制
vi /etc/security/limits.conf
root soft nproc 16384
root hard nproc 16384
root soft nofile 16384
root hard nofile 65536
root soft stack 10240
root hard stack 32768
#ORACLE SETTING
oracle soft nproc 16384
oracle hard nproc 16384
oracle soft nofile 16384
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 32768
ulimit -a
5.2 控制为用户分配的资源
echo "session required pam_limits.so" >> /etc/pam.d/login
cat /etc/pam.d/login
5.3 修改内核参数
vi /etc/sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6553600
kernel.shmall = 2147483648
kernel.shmmax = 34359738368
kernel.shmmni = 4096
kernel.sem = 2010 285420 100 142
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
sysctl -p
16G 内存修改内核参数 40-60%
cat /etc/sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6553600
kernel.shmall = 644245094
kernel.shmmax = 10307921510
kernel.shmmni = 4096
kernel.sem = 2010 285420 100 142
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
5.4 如果设置了 hugepages，还需要关闭透明页
vi /etc/rc.d/rc.local
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi
chmod +x /etc/rc.d/rc.local
6 防火墙
systemctl status firewalld.service
systemctl stop firewalld.service
systemctl disable firewalld.service
--SELINUX
vi /etc/selinux/config
SELINUX=disabled
setenforce 0
7 设置 ORACLE 用户的环境变量
su - oracle
vi .bash_profile
PS1="[`whoami`@`hostname`:"'$PWD]$'
export PS1
export TMP=/tmp
export LANG=en_US
export TMPDIR=$TMP
export ORACLE_UNQNAME=itpuxdb

ORACLE_BASE=/oracle/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/12.2.0/db_1; export ORACLE_HOME
ORACLE_TERM=xterm; export ORACLE_TERM
NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS"; export NLS_DATE_FORMAT
NLS_LANG=AMERICAN_AMERICA.ZHS16GBK;export NLS_LANG
PATH=.:$PATH:$HOME/.local/bin:$HOME/bin:$ORACLE_HOME/bin; export PATH
THREADS_FLAG=native; export THREADS_FLAG
umask=022
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v12.
2.0
oracle.install.option=INSTALL_DB_SWONLY
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/oracle/app/oraInventory

oracle.install.db.OSBACKUPDBA_GROUP=dba
oracle.install.db.OSDGDBA_GROUP=dba
oracle.install.db.OSKMDBA_GROUP=dba
oracle.install.db.OSRACDBA_GROUP=dba
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi
7 静默安装 ORACLE 软件与配置监听
