篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了CentOS7 静默安装Oracle 11gR2(11.2.0.1)相关的知识，希望对你有一定的参考价值。
最近有个项目需要迁移，项目中数据库用的是oracle，期间折腾了好久，特此记录。
一，下载Oracle
1，首先下载Oracle 11gR2，地址如下：
http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html?spm=a2c4e.11153940.blogcont566703.10.36ae6c23iChOrf
2，在页面上方勾选同意许可：
3，在下方选择对应的oracle版本，这里选择11gR2的linux x86_64版本：
一共有两个文件，注意下载前需要登录oracle账号，没有的话，注册一个就好。
下载完这两个包即可
linux.x64_11gR2_database_1of2.zip
linux.x64_11gR2_database_2of2.zip二，安装前检查
1，查看操作系统版本：
[[email protected] ~]# cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)2，查看内核版本：
[[email protected] ~]# uname -r
3.10.0-693.2.2.el7.x86_643，查看系统内存大小(oracle 11g官方建议物理内存在2G以上)：
[[email protected] ~]# cat /proc/meminfo | grep MemTotal
MemTotal: 8010460 kB4，检查防火墙是否开启：
[[email protected] ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: active (running) since Mon 2018-07-02 17:50:42 CST; 1s ago
Docs: man:firewalld(1)
Main PID: 20136 (firewalld)
CGroup: /system.slice/firewalld.service
└─20136 /usr/bin/python -Es /usr/sbin/firewalld --nofork --nopid关闭防火墙：
[[email protected] ~]# systemctl stop firewalld关闭自启动：
[[email protected] ~]# systemctl is-enabled firewalld
enabled
[[email protected] ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[[email protected] ~]# systemctl is-enabled firewalld
disabled5，关闭selinux：
[[email protected] ~]# sed -i ‘s#SELINUX=enforcing#SELINUX=disabled#g‘ /etc/sysconfig/selinux
[[email protected] ~]# setenforce 06，安装相关依赖包：
yum -y install binutils compat-libstdc++-33 compat-libcap1 gcc gcc-c++ glibc glibc-devel ksh libgcc libstdc++ libstdc++-devel libaio libaio-devel make elfutils-libelf-devel sysstat7，设置/dev/shm空间：
[[email protected] ~]# vi /etc/fstab
在fstab文件中追加如下内容：
shmfs /dev/shm tmpfs size=7g 0 0
[[email protected] ~]# mount -a
[[email protected] ~]# df -Th
Filesystem Type Size Used Avail Use% Mounted on
/dev/vda1 ext4 59G 3.8G 53G 7% /
devtmpfs devtmpfs 3.9G 0 3.9G 0% /dev
shmfs tmpfs 7.0G 0 7.0G 0% /dev/shm三，安装Oracle 11g
1，创建相关用户：
[[email protected] ~]# /usr/sbin/groupadd oinstall
[[email protected] ~]# /usr/sbin/groupadd dba
[[email protected] ~]# /usr/sbin/groupadd asmadmin
[[email protected] ~]# /usr/sbin/groupadd asmdba
[[email protected] ~]# /usr/sbin/useradd -g oinstall -G dba,asmdba oracle -d /home/oracle
[[email protected] ~]# id oracle
uid=1000(oracle) gid=1000(oinstall) groups=1000(oinstall),1001(dba),1003(asmdba)
[[email protected] ~]# passwd oracle2，调整内核参数（编辑/etc/sysctl.conf，追加如下内容）：
kernel.shmall = 2097152
kernel.shmmax = 4294967295
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 6553600
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144
#配置生效
[[email protected] ~]# sysctl -p3，增加shell限制（编辑/etc/security/limits.conf，追加如下内容）：
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 10240修改/etc/pam.d/login文件
session required /lib/security/pam_limits.so
session required pam_limits.so修改/etc/profile文件，追加如下内容：
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
4，创建必要的目录，并修改权限：
[[email protected] ~]# mkdir -p /home/app/oracle/
[[email protected] ~]# chown -R oracle:oinstall /home/app/
[[email protected] ~]# chmod -R 755 /home/app/
[[email protected] ~]# chown -R oracle:oinstall /home/oracle
[[email protected] ~]# chmod -R 775 /home/oracle5，配置/etc/hosts文件：
10.56.90.212 oracle6，配置oracle用户的环境变量：
[[email protected] ~]# su - oracle
[[email protected] ~]$ vi .bash_profile
#添加如下内容
export ORACLE_HOSTNAME=oracle
export ORACLE_UNQNAME=ora11g
export ORACLE_BASE=/home/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/
export ORACLE_SID=ORCL
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
export TMP=/tmp
export TMPDIR=$TMP
umask 022
7，解压oracle安装文件：
[[email protected] ~]$ unzip linux.x64_11gR2_database_1of2.zip
[[email protected] ~]$ unzip linux.x64_11gR2_database_2of2.zip进入到database目录，并生成响应文件：
[[email protected] ~]$ mkdir scripts
[[email protected] ~]$ cp -R database/response/ scripts/
修改response目录中的db_install.rsp文件的参数：
oracle.install.option=INSTALL_DB_SWONLY
ORACLE_HOSTNAME=oracle
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/home/app/oracle/oraInventory
SELECTED_LANGUAGES=en,zh_CN
ORACLE_HOME=/home/app/oracle/product/11.2.0
ORACLE_BASE=/home/app/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.isCustomInstall=true
oracle.install.db.DBA_GROUP=dba
oracle.install.db.OPER_GROUP=oinstall
oracle.install.db.config.starterdb.type=GENERAL_PURPOSE
oracle.install.db.config.starterdb.globalDBName=ORCL
oracle.install.db.config.starterdb.SID=ORCL
oracle.install.db.config.starterdb.characterSet=ZHS16GBK
oracle.install.db.config.starterdb.memoryOption=true
oracle.install.db.config.starterdb.installExampleSchemas=false
oracle.install.db.config.starterdb.enableSecuritySettings=true
oracle.install.db.config.starterdb.password.ALL=oracle
oracle.install.db.config.starterdb.control=DB_CONTROL
oracle.install.db.config.starterdb.dbcontrol.enableEmailNotification=false
oracle.install.db.config.starterdb.automatedBackup.enable=false8，开始静默安装数据库软件：
[[email protected] database]$ ./runInstaller -silent -responseFile /home/oracle/scripts/response/db_install.rsp -ignorePrereq
Starting Oracle Universal Installer...
Checking Temp space: must be greater than 120 MB. Actual 51039 MB Passed
Checking swap space: 0 MB available, 150 MB required. Failed <<<<
Some requirement checks failed. You must fulfill these requirements before
continuing with the installation,
这里有一个报错，提示swap不够，由于是阿里云的机器，默认没有swap空间，因此要手动创建：
[[email protected] ~]# dd if=/dev/zero of=/home/swapfile bs=1M count=2049
[[email protected] ~]# mkswap /home/swapfile
[[email protected] ~]# swapon /home/swapfile再次执行静默安装，发现又有一个报错：
Preparing to launch Oracle Universal Installer from /tmp/OraInstall2018-07-02_08-45-55PM. Please wait ...[[email protected] database]$ Exception in thread "main" java.lang.UnsatisfiedLinkError: /tmp/OraInstall2018-07-02_08-45-55PM/jdk/jre/lib/amd64/xawt/libmawt.so: libXext.so.6: cannot open shared object file: No such file or directory

解决办法是安装libXext：
[[email protected] ~]# yum install libXext -y看到如下信息时，表示数据库安装完成：
#!/bin/sh
#Root scripts to run
/home/app/oracle/oraInventory/orainstRoot.sh
/home/app/oracle/product/11.2.0/root.sh
To execute the configuration scripts:
1. Open a terminal window
2. Log in as "root"
3. Run the scripts
4. Return to this window and hit "Enter" key to continue
Successfully Setup Software.
之后，根据提示，需要执行两个相关修改权限的脚本(要切换为root用户)：
[[email protected] ~]# sh /home/app/oracle/oraInventory/orainstRoot.sh
[[email protected] ~]$ more /etc/oraInst.loc
inventory_loc=/home/app/oracle/oraInventory
inst_group=oinstall
[[email protected] ~]# sh /home/app/oracle/product/11.2.0/root.sh
9，配置静默监听：
通过response文件运行netca, 生成sqlnet.ora和listener.ora文件, 位于$ORACLE_HOME/network/admin目录下
[[email protected] ~]$ netca -silent -responsefile /home/oracle/scripts/response/netca.rsp这里可能会有一个报错：
****DISPLAY environment variable not set!
Oracle Net Configuration Assistant is a GUI tool
which requires that DISPLAY specify a location
where GUI tools can display.
Set and export DISPLAY, then re-run.
需要设置一个DISPLAY环境变量：
[[email protected] ~]$ export DISPLAY=10.66.90.222:0.0 #ip设为本机即可配置好后查看端口，发现1521已监听：
[[email protected] ~]$ netstat -tnlp
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
Active Internet connections (only servers)

tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN - 10，最后一步，静默建库。
修改response目录下的dbca.rsp文件：
SID = "ORCL"开始静默建库：
[[email protected] ~]$ dbca -silent -responseFile /home/oracle/scripts/response/dbca.rsp

至此，oracle11g安装完成。
