一、准备工作
1、下载CentOS7 自行安装（64位）网络自行配置；
2、下载Oracle安装包（转）：
oracle 11.02.0.4 安装介质
linux：https://pan.baidu.com/s/1kGsVfAoMJ_bmAJdhQgs6FA 提取码：ptn4
windows：https://pan.baidu.com/s/10wtQrYpyrhZ2dUyAEgdbFQ 提取码：frbe
参考：https://blog.csdn.net/demonson/article/details/79753766
3、HostName修改：hostnamectl set-hostname oracle
4、配置hostname（本机IP映射）
vi /etc/hosts
192.168.30.11 oracle
# 测试hostname
ping -c 3 oracle
二、优化配置
1、切换国内yum源：
cd /etc
mv yum.repos.d yum.repos.d.bak
mkdir yum.repos.d
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all
yum makecache
2、安装依赖包：
yum -y install 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
3、检查依赖是否安装完整：
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、优化OS内核参数
vim /etc/sysctl.conf #编辑，在最后添加以下代码
fs.aio-max-nr = 1048576
fs.file-max = 6815744
# shmall、shmmax参数要根据实际内存数进行调整，不然安装会有问题，静态安装很容易忽略
# 图形化安装在检测是将会提示
# 官网建议：
kernel.shmall = 2468829
# 官网建议:以字节为单位的物理内存(RAM)大小的一半
kernel.shmmax = 12640407552
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 = 1048586
#修改完后执行使参数生效。
sysctl -p
5、增加用户和组
groupadd oinstall
groupadd dba
groupadd asmadmin
groupadd asmdba
useradd -g oinstall -G dba,asmdba oracle -d /home/oracle
# 添加完成后
id oracle # 查看oracle用户
passwd oracle # 初始化oracle用户的密码
6、修改limits.conf限制
vi /etc/security/limits.conf #在末尾添加以下代码
#在末尾添加
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 10240
vi /etc/pam.d/login
session required /lib64/security/pam_limits.so
session required pam_limits.so
vi /etc/profile
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
--------------------------------------------------------
使之生效：
source /etc/profile
二、安装过程
1、创建目录
mkdir -p /db/app/oracle/product/11.2.0
mkdir /db/app/oracle/oradata
mkdir /db/app/oracle/oraInventory
mkdir /db/app/oracle/fast_recovery_area
chown -R oracle:oinstall /db/app/oracle
chmod -R 775 /db/app/oracle
2、创建 vi /etc/oraInst.loc:
inventory_loc=/db/app/oracle/oraInventory
inst_group=oinstall
3、授权：
chown oracle:oinstall /etc/oraInst.loc
chmod 664 /etc/oraInst.loc
4、配置oracle用户环境变量(注：切换用户)
su - oracle ## oracle用户登陆
vi .bash_profile
export ORACLE_HOSTNAME=oracle
export ORACLE_BASE=/db/app/oracle
export ORACLE_SID=ORCL
export LC_ALL="en_US"
export LANG="en_US"
export NLS_LANG="AMERICAN_AMERICA.ZHS16GBK"
export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"
## 以上配置完成后，建议重启系统 或分别执行以下命令：
source /home/oracle/.bash_profile
env
5、解压oracle压缩文件到 /db
Oracle11g 11.2.0.4 各个压缩包备注说明
安装单点的，就1和2一起解压，解压完叫database目录；
安装集群的，就先搞3，装完grid包后，再搞1和2；
1和2是数据库软件；
3是rac软件；
4是client客户端；
5是gateways；
6是example示例；
7是删除介质；
本次选择单点安装，解压
# 上传linux.x64_11gR2_database_*of2.zip文件至/db/目录;
unzip p13390677_112040_Linux-x86-64_1of7.zip
unzip p13390677_112040_Linux-x86-64_2of7.zip
# 解压完成后:
# 登录Root,复制授权
su - root
mkdir /home/oracle/etc/
cp database/response/* /home/oracle/etc/
chmod 777 /home/oracle/etc/*.rsp
# 登录oracle用户：
su – oracle
vi /home/oracle/etc/db_install.rsp
## 信息如下：
oracle.install.option=INSTALL_DB_SWONLY
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/db/app/oracle/oraInventory
SELECTED_LANGUAGES=en,zh_CN
ORACLE_HOSTNAME=oracle
ORACLE_HOME=/db/app/oracle/product/11.2.0/db_1
ORACLE_BASE=/db/app/oracle
oracle.install.db.InstallEdition=EE

oracle.install.db.config.starterdb.SID=orcl
oracle.install.db.config.starterdb.memoryLimit=512
oracle.install.db.config.starterdb.password.ALL=oracle
DECLINE_SECURITY_UPDATES=true
6、开始安装：
su - oracle
cd /home/oracle/database/
./runInstaller -silent -force -responseFile /home/oracle/etc/db_install.rsp -ignorePrereq
## 安装期间可以使用tail命令监看oracle的安装日志
tail -f /db/app/oracle/oraInventory/logs/installActions2021-01-16_10-01-29PM.log
[oracle@oracle database]$ ./runInstaller -silent -force -responseFile /home/oracle/etc/db_install.rsp -ignorePrereq

增加或修改oracle的环境变量:
su - oracle
vi ~/.bash_profile

至此完成数据库实例的创建。
- 如需删除实例：
[oracle@oracle ~]$ dbca -silent -deleteDatabase -sourcedb orcl
设置Oracle开机启动
一、root编辑 /etc/oratab
orcl:/db/app/oracle/product/11.2.0/db_1:N
修改为 orcl:/db/app/oracle/product/11.2.0/db_1:Y
注：参数为Y时可通过dbstart启动数据库
二、root编辑 vim /etc/rc.d/rc.local
添加以下内容：
su oracle -lc "/db/app/oracle/product/11.2.0/db_1/bin/lsnrctl start"
su oracle -lc "/db/app/oracle/product/11.2.0/db_1/bin/dbstart"
三、 oracle用户编辑dbstart
进入$ORACLE_HOME/bin
将ORACLE_HOME_LISTNER=$1 修改为 ORACLE_HOME_LISTNER=$ORACLE_HOME
分别打开两个文件找到：ORACLE_HOME_LISTNER=$1,修改为
ORACLE_HOME_LISTNER=$ORACLE_HOME，命令如下：
[oracle@oracle11g ~]$ vi $ORACLE_HOME/bin/dbstart
[oracle@oracle11g ~]$ vi $ORACLE_HOME/bin/dbshut
临时启动实例
[oracle@oracle bin]$ pwd
/db/app/oracle/product/11.2.0/db_1/bin
# 通过dbstart 启动此实例，监听器
## ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener
## Usage: ./dbstart ORACLE_HOME
[oracle@oracle bin]$ ./dbstart $ORACLE_HOME;
# oracle的进程关闭，监听器也停止;
[oracle@oracle bin]$ ./dbshut $ORACLE_HOME;
# 启动监听
[oracle@oracle bin]$ ./lsnrctl start;
# 查看监听
[oracle@oracle bin]$ ./lsnrctl status;
登录Oracle
[oracle@oracle bin]$ pwd

[oracle@oracle bin]$ ./sqlplus /nolog

解决sqlplus回退问题
Linux中安装完Oracle后，默认的 sqlplus 上下键是不能用的，安装了 rlwrap 之后就能通过上下键翻回历史命令了
- 安装readline 及 依赖

If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).

[root@oracle ~]# tar -zxvf rlwrap-0.43.tar.gz
[root@oracle ~]# cd rlwrap-0.43
[root@oracle rlwrap-0.43]# ./configure && make && make install
- 配置shell

df -h | grep shm
