Linux（Centos7）安装oracle12c

第一步：到oracle官网上下载oracle12c的镜像文件

第二步：添加用户和组

用普通用户登录后，打开命令行工具（terminal）

转到root用户

[vmtest@localhost ~]$ su root

Password:

添加组

[root@localhost vmtest]# groupadd dba

添加用户

[root@localhost vmtest]# useradd oracle

将oracle用户分配给dba组

[root@localhost vmtest]# usermod -g dba oracle

为oracle用户设置密码

[root@localhost vmtest]# passwd oracle

Changing password for user oracle.

New password:

BAD PASSWORD: The password is shorter than 8 characters

Retype new password:

passwd: all authentication tokens updated successfully.

检查刚才创建的用户和密码

[root@localhost vmtest]# tail /etc/group

gdm:x:42:

vmtest:x:1000:1000:vmtest:/home/vmtest:/bin/bash

oracle:x:1001:1001::/home/oracle:/bin/bash

第三步：创建安装目录

新建文件夹（软件目录）

[root@localhost vmtest]# mkdir -p /u01/app/oracle

将文件夹分配给用户oracle

[root@localhost vmtest]# chown oracle:dba /u01/app/oracle

设置文件夹权限

[root@localhost vmtest]# chmod 777 /u01/app/oracle

新建附属文件夹

[root@localhost vmtest]# mkdir /u01/app/oraInventory

[root@localhost vmtest]# chown oracle:dba /u01/app/oraInventory

[root@localhost vmtest]# chmod 775 /u01/app/oraInventory

验证刚才的操作

[root@localhost vmtest]# ls -l /u01/app

total 0

drwxrwxrwx. 2 oracle dba 6 Aug 2 07:52 oracle

drwxrwxr-x. 2 oracle dba 6 Aug 2 07:55 oraInventory

第四步：修改linux内核文件

打开/etc/sysctl.conf，

[root@localhost vmtest]# vi /etc/sysctl.conf

按键盘上i，进入插入模式，将红色那一段文字添加到文件末尾，按esc，然后输入:wq保存

# sysctl settings are defined through files in

 

# /usr/lib/sysctl.d/, /run/sysctl.d/, and /etc/sysctl.d/.

#

# Vendors settings live in /usr/lib/sysctl.d/.

# To override a whole file, create a new file with the same in

# /etc/sysctl.d/ and put new settings there. To override

# only specific settings, add a file with a lexically later

# name in /etc/sysctl.d/ and put new settings there.

#

# For more information, see sysctl.conf(5) and sysctl.d(5).

 

kernel.shmmax = 68719476736

kernel.shmall = 6029312

kernel.shmmni = 4096

kernel.sem =250 32000 100 128

net.core.rmem_default = 262144

修改limits文件

[root@localhost vmtest]# vi /etc/security/limits.conf

# /etc/security/limits.conf

#

#This file sets the resource limits for the users logged in viaPAM.

#It does not affect resource limits of the system services.

#

#Also note that configuration files in /etc/security/limits.ddirectory,

#which are read in alphabetical order, override the settings inthis

#file in case the domain is the same or more specific.

#That means for example that setting a limit for wildcard domainhere

#can be overriden with a wildcard setting in a config file inthe

#subdirectory, but a user specific setting here can be overridenonly

#with a user specific setting in the subdirectory.

#

#Each line describes a limit for a user in the form:

#

#          

#

#Where:

# can be:

#        - a user name

#        - a group name,with @group syntax

#        - the wildcard *,for default entry

#        - the wildcard %,can be also used with %group syntax,

#                 formaxlogin limit

#

# can have the two values:

#        -"soft" for enforcing the soft limits

#        -"hard" for enforcing hard limits

#

# can be one of the following:

#        - core - limitsthe core file size (KB)

#        - data - max data size (KB)

#        - fsize - maximumfilesize (KB)

#        - memlock - maxlocked-in-memory address space (KB)

#        - nofile - maxnumber of open file descriptors

#        - rss - maxresident set size (KB)

#        - stack - maxstack size (KB)

#        - cpu - max CPUtime (MIN)

#        - nproc - maxnumber of processes

#        - as - addressspace limit (KB)

#        - maxlogins - maxnumber of logins for this user

#        - maxsyslogins -max number of logins on the system

#        - priority - thepriority to run user process with

#        - locks - maxnumber of file locks the user can hold

#        - sigpending -max number of pending signals

#        - msgqueue - maxmemory used by POSIX message queues (bytes)

#        - nice - max nicepriority allowed to raise to values: [-20, 19]

#        - rtprio - maxrealtime priority

内核文件修改结束，重启电脑并以oracle用户登录

第五步：配置oracle用户下的概要文件

在oracle用户下，修改文件.bashrc，红色为需要添加的内容

[oracle@localhost ~]$ vi /home/oracle/.bashrc

# .bashrc

 

# Source global definitions

if [ -f /etc/bashrc ]; then

        . /etc/bashrc

fi

 

# Uncomment the following line if you don't like systemctl'sauto-paging feature:

# export SYSTEMD_PAGER=

 

# User specific aliases and functions

 

umask 002

 

ORACLE_BASE=/u01/app/oracle      //oracle安装目录，与第三步创建的安装目录相同

 

export ORACLE_BASE

 

ORACLE_HOME=$ORACLE_BASE/product/12.2.0/dbhome_1   //oracle软件包目录

 

export ORACLE_HOME

 

ORACLE_SID=orcl

 

export ORACLE_SID

 

PATH=/usr/bin:/bin:usr/local/bin:/usr/bin/X11:/usr/bin/X11R6

 

PATH=$PATH:$ORACLE_HOME/bin

 

export PATH

export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK

 

".bashrc" 37L, 515C written

 

.bash_profile环境变量设置

#vi .bash_profile

exportORACL_BASE=/u01/app/oracle         /*oracle安装目录*/
export ORACLE_HOME=/u01/app/oracle/product/12.2.0/dbhome_1   /运行目录/

exportORACLE_SID=orcl                             /数据库实例名/

export PATH=$PATH:$ORACLE_HOME/bin      /sqlplus运行目录/

 

第六步：上传并解压oracle软件包

我用的是secureCRT远程工具，用secureCRT连接到linux服务器后，定位到想上传的文件夹

# cd /home/oracle/Downloads

# rz

输入rz，打开文件框，

找到要上传的文件，点击“add”，然后点击“OK”，开始上传

注：如果服务器安装的是centos，默认会带有rzsz工具，如果没有这个工具，在服务器上下载lrzsz软件包，安装上就行。

上传之后，解压文件

用命令行检查加压后的文件是否属于用户oracle

[oracle@localhost ~]$ cd /home/oracle/Downloads

[oracle@localhost Downloads]$ ls -l

total 4176512

drwxr-xr-x. 7 oracle dba       117 Jan 27  2017 database

-rw-r--r--. 1 oracle dba 3453696911 Jul 27 08:40linuxx64_12201_database.zip

第七步：安装oracle

定位到刚才解压的文件夹

# cd /home/oracle/Downloads/database

# ./runInstaller

等一会，安装程序启动

不注册，到下一步

选第二项：只安装数据库软件，（到后面进行手动配置）

这里两个路径是第五步中设置的ORACLE_BASE和ORACLE_HOME变量

这个路径是第三步建的第二个文件夹

到这一步，会有依赖项提示，解决依赖包问题会是比较麻烦的，我们选的centos7系统本身带的依赖包是比较全的，现在我们只解决划红线这一项，其他都忽略即可。

首先查一下与所需依赖包相关的其他包的版本号

# rpm –qa | grep libaio

Libaio-0.3.109-13.el7.x86_64

现在根据这个版本号，找libaio-devel-0.3.109-13.el7.x86_64这个rpm包（网上搜）

定位到上传的文件夹

$ cd /home/oracle/Downloads

显示所有文件

$ ls

切换到root账号下，安装文件

$ su root

Password:

$ rpm –ivh libaio-devel-0.3.109-13.el7.x86_64

重新检查依赖项，发现刚才那个警告没有了。

其他三项全部忽略，如果在安装过程中还报其他依赖项的错误，反过头来按照这个步骤安装相应依赖包。

等吧…

安装完成。

切换到root用户

运行 ./root.sh

# cd $ORACLE_HOME

# ./root.sh

Performing root user operation.

 

The following environment variables are set as:

    ORACLE_OWNER= oracle

    ORACLE_HOME=  /u01/app/oracle/product/12.2.0/dbhome_1

 

Enter the full pathname of the local bin directory:[/usr/local/bin]:

   Copying dbhome to/usr/local/bin ...

   Copying oraenv to/usr/local/bin ...

   Copying coraenv to/usr/local/bin ...

 

 

Creating /etc/oratab file...

Entries will be added to the /etc/oratab file as needed by

Database Configuration Assistant when a database is created

Finished running generic part of root script.

Now product-specific root actions will be performed.

Do you want to setup Oracle Trace File Analyzer (TFA) now ?yes|[no] :

yes

Installing Oracle Trace File Analyzer (TFA).

Log File:/u01/app/oracle/product/12.2.0/dbhome_1/install/root_localhost.localdomain_2017-08-08_08-15-23-754009678.log

 

Finished installing Oracle Trace File Analyzer (TFA)

安装完成。

 

第八步：创建数据库

在命令行输入

# dbca

如果输入dbca没反应，那应该是第五步里的ORACLE_BASE和ORACLE_HOME环境变量设置错误。

等吧。。。

安装完成

第九步：配置监听（用于远程连接数据库）

在命令行输入netca

服务名与第五步里SID一致

修改配置文件

打开listener.ora

$ cd $ORACLE_HOME/network/admin

$ vi listener.ora

在文件末尾添加

SID_LIST_LISTENER=
  (SID_LIST=
      (SID_DESC=
                     #BEQUEATH CONFIG
         (GLOBAL_DBNAME=orcl)
         (SID_NAME=orcl)
        (ORACLE_HOME=/u01/app/oracle/product/12.2.0/dbhome_1)
                     #PRESPAWN CONFIG
        (PRESPAWN_MAX=20)
        (PRESPAWN_LIST=
         (PRESPAWN_DESC=(PROTOCOL=tcp)(POOL_SIZE=2)(TIMEOUT=1))
        )
       )
      )

保存，重启

 

第十步：启动数据库和监听

在命令行输入

$ sqlplus / as sysdba

启动数据库

SQL> startup

退出sql

Sql>exit

启动监听

$ lsnrctl start

OK，服务器和监听全部启动。

第十一步：其他设置

如果没有安装防火墙组件，先安装，指令如下

#yum install systemd
#yum install firewalld

关闭防火墙

# systemctl stop firewalld.service

关闭开机制动启动

# systemctl disable firewalld.service

如果客户端不是oracle12c，比如是oracle11g，需要修改文件（如果没有则新建）：

$ORACLE_HOME/network/admin/sqlnet.ora，在该文件最后添加一行文字（不需重启oracle）：

SQLNET.ALLOWED_LOGON_VERSION=8

 

在登录时，如果出现ORA-01017：用户名密码错误的信息，可能是由于oracle12c对用户名大小写敏感造成的，可以通过系统用户登录sqlplus

#sqlplus / as sysdba

并通过下列语句修改

sql> alter system set sec_case_sensitive_logon = false;

修改后如果还报用户名错误，那么在服务器端重新设置用户的密码，就可以了

Sql>alter user test1user identified by ****;

 

第十二步：测试远程连接

通过sqlplus创建表空间

SQL>  create tablespaceNOTIFYDB datafile '$ORACLE_BASE/oradata/orcl/test1.dbf' size 100M reuse autoextendon next 40M maxsize 1000M;

 

Tablespace created.

创建用户

SQL> create user test1user identified by test1pw defaulttablespace NOTIFYDB

  2  ;

 

User created.

为用户授权

SQL> grant dba to test1user;

 

Grant succeeded.

 

SQL> grant connect,resource to test1user;

 

Grant succeeded.

 

SQL> grant select any table to test1user;

 

Grant succeeded.

 

SQL> grant delete any table to test1user;

 

Grant succeeded.

 

SQL> grant update any table to test1user;

 

Grant succeeded.

 

SQL> grant insert any table to test1user;

 

Grant succeeded.

 

通过plsql连接该表空间

成功。

最后一步：设置oracle数据库和监听程序开机自动启动。

切换到root用户

编辑文件/etc/oratab

[root@localhost dbhome_1]# vi /etc/oratab

#

 

 

 

# This file is used by ORACLE utilities.  It is created by root.sh

# and updated by either Database Configuration Assistant whilecreating

# a database or ASM Configuration Assistant while creating ASMinstance.

 

# A colon, ':', is used as the field terminator.  A new line terminates

# the entry.  Linesbeginning with a pound sign, '#', are comments.

#

# Entries are of the form:

#  $ORACLE_SID:$ORACLE_HOME::

#

# 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.

#

#

 

orcl:/u01/app/oracle/product/12.2.0/dbhome_1:Y

添加上面最后一行文字，保存。

编辑文件rc.local并添加最后两行文字

[root@localhost dbhome_1]# vi /etc/rc.d/rc.local

su oracle -lc "/opt/oracle/102/bin/lsnrctl start"

#!/bin/bash

# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES

#

# It is highly advisable to create own systemd services or udevrules

# to run scripts during boot instead of using this file.

#

# In contrast to previous versions due to parallel executionduring boot

# this script will NOT be run after all other services.

#

# Please note that you must run 'chmod +x /etc/rc.d/rc.local' toensure

# that this script will be executed during boot.

 

touch /var/lock/subsys/local

 

su oracle -lc"/u01/app/oracle/product/12.2.0/dbhome_1/bin/lsnrctl start"

 

su oracle -lc/u01/app/oracle/product/12.2.0/dbhome_1/bin/dbstart

其中第一行因为lsnrctl之后有空格，需要引号，第二行加不加引号都可以。修改完保存退出即可。

但是还有一个很重要的问题，如果是在以前的centos版本中，这样就可以了。但是centos7 的/etc/rc.local不会开机执行，是因为

#!/bin/bash

# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES

#

# It is highly advisable to create own systemd services or udev rules

# to run scripts during boot instead of using this file.

#

# In constrast to previous versions due to parallel execution during boot

# this script will NOT be run after all other services.

#

# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure

# that this script will be executed during boot.

翻译：

#这个文件是为了兼容性的问题而添加的。
#强烈建议创建自己的systemd服务或udev规则来在开机时运行脚本而不是使用这个文件。
#与以前的版本引导时的并行执行相比较，这个脚本将不会在其他所有的服务后执行。
#请记住，你必须执行“chmod +x /etc/rc.d/rc.local”来确保确保这个脚本在引导时执行。

好，现在执行指令

# chmod +x /etc/rc.d/rc.local

设置完成

重启

用指令lsnrctl status 看监听程序是否打开

登录sqlplus / as sysdba

如果显示

表示数据库已经启动，

如果现实：

Connect to an idle database

说明数据库没有启动
