if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi


PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH
ORACLE_SID=D4C;export ORACLE_SID 
ORACLE_UNQNAME=D4C;export ORACLE_UNQNAME

ORACLE_BASE=/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/D4C; export ORACLE_HOME
ORACLE_TERM=xterm; export ORACLE_TERM
NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"; export NLS_DATE_FORMAT
NLS_LANG=American_America.AL32UTF8; export NLS_LANG
TNS_ADMIN=$ORACLE_HOME/network/admin; export TNS_ADMIN
ORA_NLS11=$ORACLE_HOME/nls/data; export ORA_NLS11
PATH=.:${PATH}:$HOME/bin:$ORACLE_HOME/bin:$ORA_CRS_HOME/bin
PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$ORACLE_HOME/oracm/lib
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib
export LD_LIBRARY_PATH
THREADS_FLAG=native; export THREADS_FLAG
export TEMP=/tmp
export TMPDIR=/tmp
umask 022

3. 系统配置

[oracle@dc8hdb ~]$ cat /etc/sysctl.conf|grep -v ^#|grep -v ^$
fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104
kernel.panic_on_oops = 1
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.conf.all.rp_filter = 2
net.ipv4.conf.default.rp_filter = 2
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500

4.Oracle 用户配置

groupadd oinstall
groupadd dba
groupadd oper
useradd -g oinstall -G dba,oper oracle #oracle用户的登录密码，后续登录要用，记着。
echo "Lenovo@2020" | passwd --stdin oracle
#设置密码永不过期
chage -M -1 oracle
chage -l oracle

5.关闭SELINUX

[oracle@dc8hdb ~]$ cat /etc/selinux/config|grep -v ^#|grep -v ^$
SELINUX=disabled
SELINUXTYPE=targeted 

6.修改系统对用户使用资源的限制

[root@dc8hdb ~]# cat /etc/security/limits.conf |grep -v ^#|grep -v ^$
oracle   soft   nofile    1024
oracle   hard   nofile    65536
oracle   soft   nproc    16384
oracle   hard   nproc    16384
oracle   soft   stack    10240
oracle   hard   stack    32768
oracle   hard   memlock    134217728
oracle   soft   memlock    134217728

7.开始安装

[oracle@dc8hdb LINUX.X64_193000_db_home]$ pwd
