Linux版本：CentOS7
Oracle版本：11G
安装过程：
```bash
## 1.挂载光盘
cd /mnt
mkdir cdrom
mount -t auto /dev/cdrom /mnt/cdrom
## 2.复制文件到/software目录中
mkdir /software
cp -r /mnt/cdrom /software
## 3.启动网卡
ifconfig ##查看网卡
cd /etc/sysconfig/network-scripts/
vim 网卡名称
将ONBOOT=no，修改为yes
## 4.创建oracle用户并且安装依赖
groupadd oinstall
groupadd dba
useradd -g oinstall -G dba -m oracle
passwd oracle ##（修改Oracle用户名密码。在Linux安装Oracle，必须要在Oracle用户下安装）
## 安装依赖
yum install binutils
yum install compat-libcap
yum install gcc
yum install gcc-c++
yum install glibc
yum install glibc-devel
yum install ksh
yum install libaio
yum install libgcc
yum install libstdc++
yum install libXi
yum install libXtst
yum install make
yum install sysstat
yum install unixODBC
yum install unixODBC-devel
yum -y install binutils compat compat-libstdc gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXi libXtst make sysstat unixODBC unixODBC-devel
yum install compat-libstdc++
yum install libaio
yum install glibc-static
yum -y install libstdc++.so.6
yum -y install libgmp.so.3
yum install cpp
yum install ppl
yum install cloog-ppl
yum install mpfr
chmod -Rf 777 /software
## 5.创建oracle数据库的安装目录
mkdir u01
mkdir app
mkdir /u01/app/oracle
mkdir /u01/app/oracle/fast_recovery_area
mkdir /u01/app/oracle/inventory
mkdir /u01/app/oracle/oradata
mkdir /u01/app/oracle/product
mkdir /u01/app/oracle/product/11.2.0
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/app/oracle
## 使用Oracle用户
## 6.编辑.bash_profile,最后追加
vi /home/oracle
