Title: 阿里云CentOS7 Silent Mode安装Oracle11GR2
Date: 2016-6-9Author: kagula
Environment:
[1]阿里云CentOS7-64bits 1G RAM 20G Storage[2]VMWare Workstation 11.x CentOS7-64bits 1G RAM 40G Storage
Introduction
VMWare workstation CentOS7下Silent mode方式安装Oracle11GR2 64bits.附带阿里云CentOS7额外要注意的问题。
Content
Step1:安装准备[1-1]从CentOS和Oracle官网下载
CentOS-7-x86_64-Minimal-1511.iso（阿里云不需要）
linux.x64_11gR2_database_1of2.zip
linux.x64_11gR2_database_2of2.zip
[1-2]
如果是阿里云，只有1G RAM，所以需要2G的Swap。
参考《在阿里云CentOS 7创建swap分区的方法》
http://www.111cn.net/sys/CentOS/105946.htm
我们建立2G的Swap partition.
“free -m”命令查看swap.
[1-3]
VMWare中安装CentOS7后“ls /sbin|grep ifconfig”，没有ifconfig命令
“yum install net-tools.x86_64”安装ifconfig.
[1-4]
安装Oracle所需的依赖包
yum -y install gcc gcc-c++ make binutils compat-libstdc++-33 glibc glibc-devel libaio libaio-devel libgcc libstdc++ libstdc++-devel unixODBC unixODBC-devel sysstat ksh
[1-5]创建用户和组
groupadd -g 200 oinstall #添加oinstall组，组的id为200
groupadd -g 201 dba #添加dba组，组的id为201
useradd -u 440 -g oinstall -G dba oracle #添加用户oracle,并specified它的id为440.
passwd oracle #输入oracle用户的密码
id oracle #查看用户id和所属组
对oracle的操作得使用oracle账号。
[1-6]关闭SELINUX(阿里云缺省关闭)
vim /etc/selinux/config #编辑配置文件,关闭SELINUX
setenforce 0 #立即关闭SELINUX
[1-7]
使用“su - u oracle”切换到oracle账号下
把下面两个文件上传到CentOS7-64bits服务器的/home/oracle目录下
linux.x64_11gR2_database_1of2.zip
linux.x64_11gR2_database_2of2.zip
解压缩到oracle目录下
unzip linux.x64_11gR2_database_1of2.zip -d /home/oracle
unzip linux.x64_11gR2_database_2of2.zip -d /home/oracle
在/home/oracle目录下会出现database目录。
[1-8]
“vim /home/oracle/database/response/db_install.rsp”命令配置安装参数
修改后的db_install.rsp文件内容如下:

步骤二：安装Oracle
[2-1]oracle账号登陆
在/home/oracle/database路径下执行
“./runInstaller -silent -responseFile /home/oracle/database/response/db_install.rsp”开始安装
[2-2]出现[FATAL] [INS-32012] Unable to create directory.错误提示
“chown oracle /opt”命令，修改/opt的所有者为oracle.
[2-3]再运行“./runInstaller -silent -responseFile /home/oracle/database/response/db_install.rsp”开始安装
出现[FATAL] [INS-13013] Target environment do not meet some mandatory requirements.错误
使用下面的命令重试
“ ./runInstaller -silent -ignorePrereq -ignoreSysPrereqs -responseFile /home/oracle/database/response/db_install.rsp”
等待几分钟后出现“Successfully Setup Software.”提示。
安装好后会出现“/opt/oracle/admin/orcl11g/pfile”文件夹，其中“orcl11g”是你oracle的SID，需要在环境变量中设置
否则启动listener会失败。
[2-4]按照提示以root身份登录CentOS7系统
执行下面两条命令
/opt/oraInventory/orainstRoot.sh
/opt/oracle/product/11.2.0/db_1/root.sh
[2-5]以oracle身份登录CentOS7系统，设置环境变量
vi ~/.bash_profile
追加下面的配置信息
export PATH
export ORACLE_BASE=/opt/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export PATH=$PATH:$ORACLE_HOME/bin
export ORACLE_SID=orcl11g
export TNS_ADMIN=$ORACLE_HOME/network/admin
source ~/.bash_profile
为了使sqlplus能够访问远程oracle数据库，不但要配置“TNS_ADMIN”环境变量，还需要
要环境变量指向的地址（我这里是/opt/oracle/product/11.2.0/db_1/network/admin/）中放入tnsnames.ora文件
下面是我tnsnames.ora的内容，其中orcl是数据库名字。
alioracle =因为配置好了TNS，以后你也可以参考下面的命令导入数据
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)
imp kagula/123456@alioracle file=/home/oracle/kagula20160612.dmp full=y
kagula是用户名，123456是用户密码,alioracle是上面指定的连接名。
用oracle账号调用下面的命令
“dbca -silent -responseFile /home/oracle/database/response/dbca.rsp”
出现安装进度，需要等待几分钟。
步骤三：验证Oracle安装是否成功
[3-1]
“su - u oracle”转到oracle账户下。
sqlplus "/as sysdba" 进入SQL提示符状态
select * from tabs;
如果成功运行，表示oracle已经启来，否则需要运行“startup”命令启动oracle.
[3-2]
“/opt/oracle/product/11.2.0/db_1/network/admin”路径下新建listener.ora文件
内容如下
# copyright (c) 1997 by the Oracle Corporation
#
# NAME
# listener.ora
# FUNCTION
# Network Listener startup parameter file example
# NOTES
# This file contains all the parameters for listener.ora,
# and could be used to configure the listener by uncommenting
# and changing values. Multiple listeners can be configured
# in one listener.ora, so listener.ora parameters take the form
# of SID_LIST_<lsnr>, where <lsnr> is the name of the listener
# this parameter refers to. All parameters and values are
# case-insensitive.
# <lsnr>
# This parameter specifies both the name of the listener, and
# it listening address(es). Other parameters for this listener
# us this name in place of <lsnr>. When not specified,
# the name for <lsnr> defaults to "LISTENER", with the default
# address value as shown below.

# to match the old password and to set the new one.
# LSNRCTL> set password
#Will prompt for the new password, for authentication with
# the listener. The password must be set before running the next
# command.
# LSNRCTL> save_config
# Will save the changed password to listener.ora. These last two
# steps are not necessary if SAVE_CONFIG_ON_STOP_<lsnr> is ON.

# PASSWORDS_LISTENER = 20A22647832FB454 # "foobar"
# SAVE_CONFIG_ON_STOP_<lsnr>

# while preserving formatting and comments.
# Default: OFF
# Values: ON/OFF
#
# SAVE_CONFIG_ON_STOP_LISTENER = ON
# USE_PLUG_AND_PLAY_<lsnr>
# Tells the listener to contact an Onames server and register itself
# and its services with Onames.
# Values: ON/OFF
# Default: OFF
#
# USE_PLUG_AND_PLAY_LISTENER = ON
# LOG_FILE_<lsnr>
# Sets the name of the listener's log file. The .log extension
# is added automatically.
# Default=<lsnr>
#
# LOG_FILE_LISTENER = lsnr
# LOG_DIRECTORY_<lsnr>
# Sets the directory for the listener's log file.
# Default: <oracle_home>/network/log
#
# LOG_DIRECTORY_LISTENER = /private/app/oracle/product/8.0.3/network/log
# TRACE_LEVEL_<lsnr>
# Specifies desired tracing level.
# Default: OFF
# Values: OFF/USER/ADMIN/SUPPORT/0-16
#
# TRACE_LEVEL_LISTENER = SUPPORT
# TRACE_FILE_<lsnr>
# Sets the name of the listener's trace file. The .trc extension
# is added automatically.
# Default: <lsnr>
#
# TRACE_FILE_LISTENER = lsnr
# TRACE_DIRECTORY_<lsnr>
# Sets the directory for the listener's trace file.
# Default: <oracle_home>/network/trace
#
# TRACE_DIRECTORY_LISTENER=/private/app/oracle/product/8.0.3/network/trace
# CONNECT_TIMEOUT_<lsnr>
# Sets the number of seconds that the listener waits to get a
# valid database query after it has been started.
# Default: 10
#
# CONNECT_TIMEOUT_LISTENER=10
其中HOST中的地址要改成你CentOS7机器的IP地址,否则“lsnrctl start”命令启动侦听器，会报TNS-01189错误。
[3-3]在windows系统上测试CentOS7服务器上的Oracle是否可以链接
在Windows操作系统上下载win64_11gR2_client.zip解压缩后
admin模式下用" setup -ignoreSysPrereqs"命令安装。
参考《Oracle的tnsnames.ora配置(PLSQL Developer)》
http://jingyan.baidu.com/article/b0b63dbfcd34834a4930704a.html
链接服务器，如果遇到超时错误
服务器执行“systemctl stop firewalld”临时关闭防火墙试试看。
这里奇怪的是执行“firewall-cmd --permanent --query-port=1521/tcp”命令看到端口已经开放，
后来发现得用“ firewall-cmd --list-all”命令才能真正看到端口是否开放。
