首先有两个脚本作为oracle的基础环境配置：
(1)[root@localhost opt]# cat rpm.txt
binutils
compat-libcap1
compat-libstdc++*
compat-libstdc++*
gcc
gcc-c++
glibc
glibc-devel
ksh
libgcc
libstdc++
libstdc++-devel
libaio
libaio-devel
make
sysstat
unixODBC*
这些主要是oracle的依赖包，并且都存在于yum源中，可采用如下命令进行安装：
#yum -y install $(cat rpm.txt)
(2)基础环境配置的脚本：
[root@localhost opt]# cat test.sh
ORACLE_SID=zydb
ORACLE_BASE=/db/oracle
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
groupadd oinstall
groupadd dba
groupadd oper
##user
useradd -g oinstall -G dba,oper oracle
passwd oracle
passwd --stdin oracle <<EOF
oracle
oracle
EOF

需要执行下这个脚本sh test.sh
这俩个在附件中采用oracle.zip存储，https://files.cnblogs.com/baoyiluo/oracle.zip
然后就是实际安装oracle数据库了。
1解压俩个相关的oracle包，这个比较大2G。

2.cd database;
3../runInstaller
如果遇到目录不正确的错误，在对应目录中间添加oracle。
有一步需要对一些信息进行忽略，勾选图形框的右上角ignore all，才能进行下一步安装。
