静默安装分5步
0. 系统配置（预条件）
1. Prepare a response file.
2. Run Oracle Universal Installer in silent or response file mode.
3. Run the root scripts as prompted by Oracle Universal Installer.
4. If you completed a software-only installation, then run Net Configuration Assistant and Database Configuration Assistant in silent or response file mode, if required.

创建一个配置文件，包含oraInventory目录位置，最好放在ORACLE_BASE下面
#vi /etc/oraInst.loc
# chown digoal:users /etc/oraInst.loc
inventory_loc=/home/digoal/oracle/product/oraInventory
inst_group=users
$./runInstaller -silent -responseFile /home/digoal/db_install.rsp
如果安装遇到错误，比如前提条件未满足，可以通过日志查看，搜索FAIL
例如
INFO: *********************************************
INFO: OS Kernel Parameter: wmem_default: This is a prerequisite condition to test whether the OS kernel parameter "wmem_default" is properly set.
INFO: Severity:IGNORABLE
INFO: OverallStatus:WARNING
INFO: -----------------------------------------------
INFO: Verification Result for Node:digoal_host
INFO: Expected Value:262144
INFO: Actual Value:Current=262144; Configured=unknown
INFO: Error Message:PRVG-1201 : OS kernel parameter "wmem_default" does not have expected configured value on node "digoal_host" [Expected = "262144" ; Current = "262144"; Configured = "unknown"].
INFO: Cause: A check of the configured value for an OS kernel parameter did not find the expected value.
INFO: Action: Modify the kernel parameter configured value to meet the requirement.
INFO: -----------------------------------------------
以上说明对应的OS内核参数需要配置一下。
正常情况下，结束时会输出如下

# This file is used by ORACLE utilities. It is created by root.sh
# and updated by either Database Configuration Assistant while creating
# a database or ASM Configuration Assistant while creating ASM instance.
# A colon, ':', is used as the field terminator. A new line terminates
# the entry. Lines beginning with a pound sign, '#', are comments.
#
# Entries are of the form:
# $ORACLE_SID:$ORACLE_HOME:<N|Y>:
#
# The first and second fields are the system identifier and home
# directory of the database respectively. The third field indicates
# to the dbstart utility that the database should , "Y", or should not,
# "N", be brought up at system boot time.
#
# Multiple entries with the same $ORACLE_SID are not allowed.

不够可以再加。
后面再讲数据库初始化。
