Redhat7安装oracle需要安装的依赖，创建的文件夹，修改的依赖

一、需要安装的依赖

yum install -y binutils
yum install -y compat-libcap1
yum install -y compat-libstdc++-33
yum install -y compat-libstdc++-33.i686
yum install -y gcc

yum install -y python
yum install -y python-configshell
yum install -y python-rtslib
yum install -y python-six
yum install -y targetcli
yum install -y smartmontools

注：如果compat-libstdc++这个软件包显示没有，就用yum -y install http://mirror.centos.org/centos/7/os/x86_64/Packages/compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm

二、创建需要的用户

groupadd -g 11001 oinstall
groupadd -g 11002 dba
groupadd -g 11003 oper
groupadd -g 11004 backupdba
groupadd -g 11005 dgdba
groupadd -g 11006 kmdba
groupadd -g 11007 asmdba
groupadd -g 11008 asmoper
groupadd -g 11009 asmadmin
groupadd -g 11010 racdba
useradd -u 11011 -g oinstall -G dba,asmdba,backupdba,dgdba,kmdba,racdba,oper oracle
useradd -u 11012 -g oinstall -G asmadmin,asmdba,asmoper,dba grid

三、创建需要的目录

mkdir -p /u01/app/19.0.0/grid
mkdir -p /u01/app/grid
mkdir -p /u01/app/oracle
mkdir -p /u01/app/oracle/product/19.0.0/db_1
chown -R grid:oinstall /u01/app/grid
chown -R grid:oinstall /u01/app/19.0.0/grid
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/

四、需要修改的参数

vim /etc/security/limits.d/20-nproc.conf
# Change this
#注释这行* soft nproc 1024
# To this 增加下面一行
* - nproc 16384

vim /etc/security/limits.conf
#ORACLE SETTING
grid soft nproc 16384
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
grid soft stack 10240
grid hard stack 32768
oracle soft nproc 16384
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 32768
oracle hard memlock 4194304
oracle soft memlock 4194304
##memlock 这个值还是应该比内存配置略小，也就是要配置的足够大。单位：k
##4194304 表示 4G

vim /etc/pam.d/login
#ORACLE SETTING
session required pam_limits.so

vim /etc/sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 18446744073692774399
kernel.shmmax = 18446744073692774399
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
