1、环境及准备工作

1.1 环境及配置调整

操作系统版本、内核版本、系统CPU、RAM、硬盘配置如下

[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)
[root@localhost ~]# uname -r
3.10.0-1062.el7.x86_64
[root@localhost ~]# cat /proc/cpuinfo| grep "processor"| wc -l
8
[root@localhost ~]# cat /proc/meminfo| grep MemTotal
MemTotal:       131826144 kB
[root@localhost ~]# cat /proc/meminfo| grep SwapTotal
SwapTotal:       1835004 kB
[root@localhost ~]# fdisk -l|grep Disk
Disk /dev/vda: 21.5 GB, 21474836480 bytes, 41943040 sectors
Disk label type: dos
Disk identifier: 0x000e4fd0
Disk /dev/vdb: 2199.0 GB, 2199023255552 bytes, 4294967296 sectors
Disk /dev/mapper/centos-root: 18.5 GB, 18513657856 bytes, 36159488 sectors
Disk /dev/mapper/centos-swap: 1879 MB, 1879048192 bytes, 3670016 sectors

如下表所示

项目	值
操作系统	CentOS Linux release 7.7.1908 (Core)
内核版本	3.10.0-1062.el7.x86_64
CPU	8C
RAM	128GB
SWAP	1GB
磁盘	/dev/vda 20G + /dev/vdb 2TB

数据盘未做格式化分区（这里仅格式化并挂载到单独目录，不做分区）
根据内存大小需要对此操作系统重新分配合适的swap空间（这里增加到16G），关于swap分区大小可参考红帽官方说明

[root@localhost ~]# mkfs.xfs /dev/vdb
[root@localhost ~]# mkdir /data && mount /dev/vdb /data
[root@localhost ~]# df -h | grep "data"
/dev/vdb                 2.0T   33M  2.0T   1% /data
[root@localhost ~]# blkid |grep vdb|awk '{print $2}'|cut -d '=' -f 2
"11eda493-b248-4ce0-91fb-e28e1b8164a9"
[root@localhost ~]# echo "UUID=11eda493-b248-4ce0-91fb-e28e1b8164a9 /data                   xfs     defaults        0 0" >> /etc/fstab  # 开机自动挂载数据盘
[root@localhost ~]# sed -ri '/^[^#]*swap/s@^@#@' /etc/fstab  # 关掉原来的swap开机自动挂载
[root@localhost ~]# dd if=/dev/zero of=/data/swapfile bs=1G count=16
[root@localhost ~]# mkswap /data/swapfile
[root@localhost ~]# chmod 600 /data/swapfile
[root@localhost ~]# swapon /data/swapfile
[root@localhost ~]# echo "/data/swapfile           swap                    swap    defaults        0 0" >> /etc/fstab  # 开机自动挂载swap分区

1.2 常用参数

修改主机名、关闭selinux、时间同步等

[root@localhost ~]# hostnamectl set-hostname oracledb-01
[root@localhost ~]# echo "127.0.0.1   oracledb-01" >> /etc/hosts
[root@oracledb-01 ~]# sestatus
SELinux status:                 disabled

1.3 其他准备

• 安装依赖

  [root@oracledb-01 ~]# yum -y install binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-dev libXi libXtst make sysstat unixODBC unixODBC-devel
  

• 下载oracle安装包

  从官网下载linux 64位安装包，下载后两个文件如下

  [root@oracledb-01 ~]# ls linux.x64_11gR2_database_2of2
  linux.x64_11gR2_database_1of2.zip  linux.x64_11gR2_database_2of2.zip
  

• 创建用户：安装Oracle数据库，需要以下本地操作系统组和用户

  • Oracle inventory组(通常为 oinstall)
  • OSDBA组 (通常为 dba)
  • OSOPER组 (通常为 oper)
  • Oracle软件所有者(通常为 oracle)

  [root@oracledb-01 ~]# groupadd oinstall
  [root@oracledb-01 ~]# groupadd dba
  [root@oracledb-01 ~]# groupadd oper
  [root@oracledb-01 ~]# useradd -g oinstall -G dba oracle
  

• 修改oracle用户的密码

  [root@oracledb-01 ~]# echo "oracle" | passwd --stdin oracle
  Changing password for user oracle.
  passwd: all authentication tokens updated successfully.
  

• 配置资源限制和内核参数

  在/etc/sysctl.conf添加如下参数，如果系统中某个参数高于下面的参数的值，保留较大的值，下面的数值只是官方要求的最小值，可以根据系统调整数值，以优化系统性能

  fs.aio-max-nr = 1048576	# 同时可以拥有的的异步IO请求数目
  fs.file-max = 6815744		# 指定可以分配的文件句柄的最大数目
  kernel.shmall = 2097152	# 共享内存总量
  kernel.shmmax = 536870912	# 共享内存段的最大尺寸
  kernel.shmmni = 4096	# 系统范围内共享内存段的最大数量
  kernel.sem = 250 32000 100 128
  net.ipv4.ip_local_port_range = 9000 65500
  net.core.rmem_default = 262144	# 接收缓冲区大小
  net.core.rmem_max = 4194304	# 接收缓冲区最大值
  net.core.wmem_default = 262144	# 默认的发送缓冲区大小
  net.core.wmem_max = 1048576	# 发送缓冲区最大值
  

  使内核参数生效

  [root@oracledb-01 ~]# sysctl -p
  

  编辑/etc/security/limits.conf（用户限制配置文件），添加如下参数

  oracle              soft    nproc   2047
  oracle              hard    nproc   16384
  oracle              soft    nofile  1024
  oracle              hard    nofile  65536
  

  编辑/etc/pam.d/login文件，将配置文件加入到登录验证模块

  #Add for Install Oracle Database 11g
  session required  /lib64/security/pam_limits.so
  session required  pam_limits.so
  

  编辑/etc/profile文件（环境变量文件）

  [root@oracledb-01 ~]# vim /etc/profile
  if [ $USER = "oracle" ]; then
     if [ $SHELL = "/bin/ksh" ]; then
         ulimit -p 16384
         ulimit -n 65536
      else
         ulimit -u 16384 -n 65536
     fi
  fi
  [root@oracledb-01 ~]# source /etc/profile
  

  禁用使用Transparent HugePages(启用Transparent HugePages，可能会导致造成内存在运行时的延迟分配，Oracle官方建议使用标准的HugePages)

  • 查看是否启用 如果显示 [always]说明启用了

  • 禁用Transparent HugePages,在/etc/grub.conf添加如下内容

  [root@oracledb-01 ~]# cat /sys/kernel/mm/transparent_hugepage/enabled
  [always] madvise never
  [root@oracledb-01 ~]# echo never > /sys/kernel/mm/transparent_hugepage/enabled
  

  重新启动系统以使上述更改成为永久更改

2、oracle安装

2.1 基本配置

• 创建oracle安装目录

  [root@oracledb-01 ~]# mkdir -p /data/app/
  [root@oracledb-01 ~]# chown -R oracle:oinstall /data/app/
  [root@oracledb-01 ~]# chmod -R 775 /data/app/
  

• 配置oracle用户环境变量
  在文件/home/oracle/.bash_profile里添加下面内容

  umask 022
  export ORACLE_HOSTNAME=oracledb-01  # 修改成主机名
  export ORACLE_BASE=/data/app/oracle
  export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/
  export ORACLE_SID=ORCL
  export ORACLE_UNQNAME=orcl
  export PATH=.:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$ORACLE_HOME/jdk/bin:$PATH
  export LC_ALL="en_US"
  export LANG="en_US"
  export NLS_LANG="AMERICAN_AMERICA.ZHS16GBK"
  export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"
  

  由于新增了环境变量，再次重启系统

2.2 解压安装包

[root@oracledb-01 ~]# cd linux.x64_11gR2_database_2of2/
[root@oracledb-01 linux.x64_11gR2_database_2of2]# ls
linux.x64_11gR2_database_1of2.zip  linux.x64_11gR2_database_2of2.zip
[root@oracledb-01 linux.x64_11gR2_database_2of2]# unzip -q linux.x64_11gR2_database_1of2.zip -d /data
[root@oracledb-01 linux.x64_11gR2_database_2of2]# unzip -q linux.x64_11gR2_database_2of2.zip -d /data
[root@oracledb-01 linux.x64_11gR2_database_2of2]# mkdir -p /data/etc
[root@oracledb-01 linux.x64_11gR2_database_2of2]# cp /data/database/response/* /data/etc/

2.3 正式安装

修改文件/data/etc/db_install.rsp中以下变量的值

oracle.install.option=INSTALL_DB_SWONLY
DECLINE_SECURITY_UPDATES=true
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/data/app/oracle/inventory
SELECTED_LANGUAGES=en,zh_CN
ORACLE_HOSTNAME=oracledb-01  # 修改成主机名
ORACLE_HOME=/data/app/oracle/product/11.2.0
ORACLE_BASE=/data/app/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.isCustomInstall=true
oracle.install.db.DBA_GROUP=dba
oracle.install.db.OPER_GROUP=dba

执行安装脚本

[root@oracledb-01 ~]# su - oracle
[oracle@oracledb-01 ~]$ cd /data/database/
[oracle@oracledb-01 database]$ ./runInstaller -silent -responseFile /data/etc/db_install.rsp -ignorePrereq

安装时可以根据安装提示查看日志

[root@oracledb-01 ~]# tail -f /data/app/oracle/inventory/logs/installActions2020-10-31_09-40-21PM.log

安装完成后会有如下提示

You can find the log of this install session at:
 /data/app/oracle/inventory/logs/installActions2020-10-31_09-40-21PM.log
The following configuration scripts need to be executed as the "root" user. 

 #!/bin/sh
 #Root scripts to run

/data/app/oracle/inventory/orainstRoot.sh
/data/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.

按照上述提示进行操作，使用root用户运行脚本

[oracle@oracledb-01 ~]$ su - root

查看监听端口

[oracle@oracledb-01 database]$ netstat -tnpl | grep 1521
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)

2.4 静默创建数据库

2.4.1 编辑应答文件

编辑应答文件/data/etc/dbca.rsp

[GENERAL]
RESPONSEFILE_VERSION = "11.2.0"
OPERATION_TYPE = "createDatabase"
[CREATEDATABASE]
GDBNAME = "orcl"
SID = "orcl"
SYSPASSWORD = "oracle"
SYSTEMPASSWORD = "oracle"
SYSMANPASSWORD = "oracle"
DBSNMPPASSWORD = "oracle"
DATAFILEDESTINATION = /data/app/oracle/oradata
RECOVERYAREADESTINATION=/data/app/oracle/fast_recovery_area
CHARACTERSET = "AL32UTF8"  # 字符集，根据需求设置，建议前期确定好需要什么字符集，后期不建议更改
TOTALMEMORY = "102400"  # 分配给Oracle的内存总量，根据服务器内存总量进行分配

2.4.2 执行静默建库

su - oracle
dbca -silent -responseFile /data/etc/dbca.rsp

执行时控制台输出如下

添加执行权限和开机启动

[root@oracledb-01 ~]# chmod +x /etc/init.d/oracle
[root@oracledb-01 ~]# chkconfig oracle on
[root@oracledb-01 ~]# chkconfig --list|grep oracle

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

      If you want to list systemd services use 'systemctl list-unit-files'.
      To see services enabled on particular target use
      'systemctl list-dependencies [target]'.

oracle          0:off   1:off   2:on    3:on    4:on    5:on    6:off

修改启动相关文件的权限

[root@oracledb-01 ~]# cd /data/app/oracle/product/11.2.0/bin/
[root@oracledb-01 bin]# chmod 6751 oracle
[root@oracledb-01 bin]# cd /var/tmp
[root@oracledb-01 tmp]# chown -R oracle:oinstall .oracle

关机重启测试

reboot

关机重启后登陆进入数据库后，再执行startup启动数据库。
