前置配置 

 

安装所需系统环境

yum -y install deltarpm python-deltarpm bc compat-libcap1* compat-libcap* binutils  compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc-2.5 glibc-common glibc-devel glibc-headers ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel binutils* compat-libstdc*  elfutils-libelf* gcc* glibc* ksh* libaio* libgcc* libstdc* make* sysstat* libXp* glibc-kernheaders net-tools-*

如果没有图形化则安装，有则跳过这一步

yum -y groupinstall  gnome-desktop  

ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target

reboot

#重启后就有图形化

关闭防火墙和seLinux

systemctl stop firewalld

setenforce 0

修改Linux内核

vim /etc/sysctl.conf插入kernel.shmmax = 277495689510912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
fs.file-max = 6815744
kernel.shmall = 67747971072
net.ipv4.tcp_max_tw_buckets = 6000
net.ipv4.ip_local_port_range = 9000 65500
net.ipv4.tcp_tw_recycle = 0

net.ipv4.tcp_timestamps = 0
fs.aio-max-nr = 1048576
net.ipv4.conf.all.rp_filter = 2
net.ipv4.conf.default.rp_filter = 2

sysctl -p

限制占用
 

vim /etc/security/limits.conf插入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

修改信息

vim /etc/pam.d/login插入session required /lib/security/pam_limits.so
session required pam_limits.so

修改环境变量

vim /etc/profile插入if [ $USER = "oracle" ]; thenif [ $SHELL = "/bin/ksh" ]; thenulimit -p 16384ulimit -n 65536elseulimit -u 16384 -n 65536fi
fi

source /etc/profile

创建用户和组以及目录

groupadd oinstall
groupadd dba
groupadd oper
useradd -g oinstall -G dba,oper oracle
mkdir -p  /u01/app/oracle
mkdir -p  /u01/oraInventory
chown -R  oracle.oinstall  /u01
chown -R  oracle:oinstall  /u01/app/oracle
chmod -R  775  /u01/app/oracle
mkdir -p /u01/app/oracle/product/19c/db_1
chown -R oracle:oinstall /u01/app/oracle/product/

passwd oracle

设置oracle变量

su - oracle

vim .bash_profile插入export EDITOR=vi
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_SID=orcl
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/19c/db_1
export INVENTORY_LOCATION=/u01/oraInventory
export TNS_ADMIN=$ORACLE_HOME/network/admin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export NLS_LANG="AMERICAN_AMERICA.AL32UTF8"
export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"
export PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin:$PATH:$HOME/bin
umask 022

source .bash_profile

补一个文件

cp /root/.Xauthority /home/oracle/.Xauthority

---

开始安装

cd /u01/app/oracle/product/19c/db_1

在/u01/app/oracle/product/19c/db_1放入LINUX.X64_193000_db_home.zip包

unzip LINUX.X64_193000_db_home.zip

export DISPLAY=192.168.6.254:0.0

你真机连接你虚拟机网卡的ip 

./runInstaller

如果报错了就        export DISPLAY=localhost:10.0  再 ./runInstaller

 

 

 

 

 

复制这两句话到Linux中以root执行
