操作步骤
A、环境准备
B、用户组创建
C、修改系统内核参数
D、修改用户配置
E、数据库应用安装
F、数据库初始化
A、环境准备
1、选择Oracle安装包，直接去官网选择自己需要的版本（需要注册oracle账号），如果下载不了的话也可以联系我度盘共享。
地址：https://www.oracle.com/technetwork/cn/database/enterprise-edition/downloads/index.html
2、使用root用户登录，进行系统基础环境准备。
执行以下命令：
yum -y install binutils compat-libcap1 compat-libstdc++-33 compat-libstdc++-33*i686 compat-libstdc++-33*.devel compat-libstdc++-33 compat-libstdc++-33*.devel gcc gcc-c++ glibc glibc*.i686 glibc-devel glibc-devel*.i686 ksh libaio libaio*.i686 libaio-devel libaio-devel*.devel libgcc libgcc*.i686 libstdc++ libstdc++*.i686 libstdc++-devel libstdc++-devel*.devel libXi libXi*.i686 libXtst libXtst*.i686 make sysstat unixODBC unixODBC*.i686 unixODBC-devel unixODBC-devel*.i686
静待系统进行软件更新安装，成功后如下：
执行检查命令：
rpm -q binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXi libXtst make sysstat unixODBC unixODBC-devel
5
B、用户组创建
1、创建 oinstall 和 dba 组
zrgldb:/root/> groupadd oinstall zrgldb:/root/> groupadd dba
2、创建 oracle 用户，设置密码
jrxxfwb-zrgldb:/root/> useradd -g oinstall -G dba oracle jrxxfwb-zrgldb:/root/> passwd oracle Changing password for user oracle. New password: BAD PASSWORD: it is based on a dictionary word BAD PASSWORD: is too simple Retype new password: BAD PASSWORD: The password is shorter than 8 characters Retype new password: passwd: all authentication tokens updated successfully.
3、查看用户 id oracle
zrgldb:/root/> id oracle uid=1004(oracle) gid=1004(oinstall) groups=1004(oinstall),1005(dba)
C、修改系统内核参数
1、修改系统配置： vi /etc/sysctl.conf ，增加如下内容：
fs.aio-max-nr = 1048576 fs.file-max = 6815744
# shmall 是全部允许使用的共享内存大小，shmmax 是单个段允许使用的大小。这两个可以设置为内存的 90%。例如 16G 内存，16*1024*1024*1024*90% = 15461882265，shmall 的大小为 15461882265/4k(getconf PAGESIZE可得到) = 3774873
# 因为本机是32G内存，所以shmmax 是 32*1024*1024*1024*90% = 30,923,764,531，shmall 是 30,923,764,531/4096 = 7,549,747
kernel.shmmax = 30923764531
kernel.shmall = 7549747 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576
结果如下：
2、使配置生效： sysctl -p
D、修改用户配置
1、修改用户限制。
打开文件： vi /etc/security/limits.conf
在文件末尾添加如下6行内容：
oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft stack 10240 oracle hard stack 10240
最终结果如图：
2、修改用户登录库文件引用
打开系统文件： vi /etc/pam.d/login
在文件末尾添加如下2行内容：
session required /lib64/security/pam_limits.so
session required pam_limits.so
最终结果如图：
3、修改用户登录环境变量
打开系统文件： vi /etc/profile
在文件末尾添加如下内容：
if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi fi
最终结果如图：
退出编辑状态，使修改的文件生效：
source /etc/profile
4、创建安装目录，配置安装目录权限。
mkdir -p /usr/app/ chown -R oracle:oinstall /usr/app/ chmod -R 775 /usr/app/
5、配置 Oracle 用户环境变量
切换用户： su – oracle
编辑环境变量： vi .bash_profile
新增配置如下：
export ORACLE_BASE=/usr/app/oracle export ORACLE_SID=orcl export PS1=`uname -n`':$PWD/> '
生效配置文件： source .bash_profile
E、数据库应用安装
1、使用 oracle 用户，创建数据库安装配置文件夹 etc 。
zrgldb://> su - oracle
zrgldb:/home/oracle/> mkdir etc
2、上传安装文件到 oracle 用户目录下，并解压文件。
执行命令：
zrgldb:/home/oracle/> unzip linuxamd64_12102_database_1of2.zip
zrgldb:/home/oracle/> unzip linuxamd64_12102_database_2of2.zip
解压完成会在用户目录下出现一个 database 文件夹，如下：
3、复制 Oracle配置文件到 etc 目录下，并修改配置文件权限
zrgldb:/home/oracle/> cp ./database/response/* ./etc/
zrgldb:/home/oracle/> chmod 700 ./etc/*.rsp
复制后的etc目录文件如下：
4、修改静默安装配置文件 db_install.rsp
vi ./etc/db_install.rsp

Look这里
5、开始安装，执行 db_install.rsp
zrgldb:/home/oracle/> ./database/runInstaller -silent -responseFile /home/oracle/etc/db_install.rsp
Starting Oracle Universal Installer...
Checking Temp space: must be greater than 500 MB. Actual 44203 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,
Continue? (y/n) [n]
报错了。我直接输入 n退出了，当然输入 y 也可能安装成功，避免失败，我还是把问题解决一下。如果没报错直接进行安装操作，跳过以下步骤。
一、是没有swap空间
① 检查一下系统的 swap 文件
zrgldb:/home/oracle/> swapon –s swapon: stat failed –s: No such file or directory
说明系统不存在swap
② 切换 root 用户，创建swap文件
zrgldb:/root/> dd if=/dev/zero of=/swapfile bs=1024 count=512k
524288+0 records in
524288+0 records out
536870912 bytes (537 MB) copied, 1.49301 s, 360 MB/s
③ 格式化并激活 Swap 文件
zrgldb:/root/> mkswap /swapfile Setting up swapspace version 1, size = 524284 KiB no label, UUID=ea40b04c-238c-41b1-8f83-7d36b8b7fd66
zrgldb:/root/> swapon /swapfile
swapon: /swapfile: insecure permissions 0644, 0600 suggested.
④ 再次检查系统的 Swap 文件
zrgldb:/root/> swapon -s Filename Type Size Used Priority /swapfile file 524284 0 -1
⑤ 配置机器重启自动挂载Swap，修改 fstab 配置：vi /etc/fstab
添加一行
/swapfile swap swap defaults 0 0
⑥ 赋予 Swap 文件权限
zrgldb://> chmod 600 /swapfile zrgldb://> chown root:root /swapfile
切换到 oracle 用户 ，再次执行本部操作的数据库安装命令：
zrgldb:/home/oracle/> ./database/runInstaller -silent -responseFile /home/oracle/etc/db_install.rsp Starting Oracle Universal Installer... Checking Temp space: must be greater than 500 MB. Actual 43690 MB Passed Checking swap space: must be greater than 150 MB. Actual 511 MB Passed Preparing to launch Oracle Universal Installer from /tmp/OraInstall2019-08-01_03-16-16PM. Please wait ...

You can find the log of this install session at:
/usr/app/oracle/oraInventory/logs/installActions2019-08-01_03-20-39PM.log
The installation of Oracle Database 12c was successful.
Please check '/usr/app/oracle/oraInventory/logs/silentInstall2019-08-01_03-20-39PM.log' for more details.
As a root user, execute the following script(s):
1. /usr/app/oracle/oraInventory/orainstRoot.sh
2. /usr/app/oracle/product/12/db_1/root.sh
Successfully Setup Software.
等待结果，这样安装就成功完成了。
6、切换 root 用户，修改数据库配置
zrgldb://> /usr/app/oracle/oraInventory/orainstRoot.sh Changing permissions of /usr/app/oracle/oraInventory. Adding read,write permissions for group. Removing read,write,execute permissions for world. Changing groupname of /usr/app/oracle/oraInventory to oinstall. The execution of the script is complete. jrxxfwb-zrgldb://> /usr/app/oracle/product/12/db_1/root.sh Check /usr/app/oracle/product/12/db_1/install/root_jrxxfwb-zrgldb_2019-08-01_15-29-54.log for the output of root script
F、数据库初始化
1、使用 oracle 用户登录，修改用户环境变量
export ORACLE_BASE=/usr/app/oracle export ORACLE_SID=orcl export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib export ORACLE_HOME=/usr/app/oracle/product/12/db_1 export PATH=$PATH:$ORACLE_HOME/bin export LANG="zh_CN.UTF-8" export NLS_LANG="SIMPLIFIED CHINESE_CHINA.AL32UTF8" export NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss'
使环境变量生效，执行命令：source .bash_profile
2、配置监听程序
zrgldb:/home/oracle/> netca /silent /responsefile /home/oracle/etc/netca.rsp
3、启动监听
zrgldb:/home/oracle/> lsnrctl start
LSNRCTL for Linux: Version 12.1.0.2.0 - Production on 01-8月 -2019 15:47:15
Copyright (c) 1991, 2014, Oracle. All rights reserved.
4、静默建库文件修改，打开 dbca.rsp 文件。
vi ./etc/dbca.rsp
#----------------------------------------------------------------------------- # Name : SID # Datatype : String # Description : System identifier (SID) of the database # Valid values : Check Oracle12c Administrator's Guide # Default value : <db_name> specified in GDBNAME # Mandatory : No #----------------------------------------------------------------------------- SID = "orcl" #----------------------------------------------------------------------------- # Name : CHARACTERSET # Datatype : String # Description : Character set of the database # Valid values : Check Oracle12c National Language Support Guide # Default value : "US7ASCII" # Mandatory : NO #----------------------------------------------------------------------------- CHARACTERSET = "AL32UTF8" #----------------------------------------------------------------------------- # Name : LISTENERS # Datatype : String # Description : Specifies list of listeners to register the database with. # By default the database is configured for all the listeners specified in the # $ORACLE_HOME/network/admin/listener.ora # Valid values : The list should be comma separated like "listener1,listener2". # Mandatory : NO #----------------------------------------------------------------------------- LISTENERS = "LISTENERS"
5、执行静默建库
zrgldb:/home/oracle/> dbca -silent -createDatabase -responseFile /home/oracle/etc/dbca.rsp

6、创建数据库应用用户并授权。
zrgldb:/home/oracle/> sqlplus / as sysdba SQL*Plus: Release 12.1.0.2.0 Production on 星期四 8月 1 16:45:33 2019 Copyright (c) 1982, 2014, Oracle.
