准备工作(安装环境)

1. 使用VMware14 搭建centos7的虚拟机

ip:192.168.126.129

2. 下载Oracle11g安装文件

链接: https://pan.baidu.com/s/1DaMJ8Nei5a9tUfDfvHd8Jw 提取码: nhv6
在这里插入图片描述

3.使用xhell5工具连接虚拟机，把两个文件上传到/home目录下

使用命令

[root@localhost ~]# cd /home  进去home目录中
[root@localhost home]#  rz     拉起windows资源管理器选择你Oracle11g的目录

4.使用root用户登录linux，yum安装unzip软件，用来解压上传的oracle安装文件

[root@localhost home]# yum install unzip –y

5…解压oracle安装程序

[root@localhost home]# unzip linux.x64_11gR2_database_1of2.zip
 
[root@localhost home]# unzip linux.x64_11gR2_database_2of2.zip

解压完成后，在/home目录下生成一个database文件夹，里面就是oracle安装文件

6. yum安装vim软件，用于编辑配置文件

[root@localhost home]#yum install vim -y

7.在/etc/hosts文件中添加主机名

a. 查看主机名

[root@localhost home]# hostname
localhost.localdomain
[root@localhost home]#

b. 添加到hosts文件中

[root@localhost home]# vim /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.126.129 localhost.localdomain

8.关掉selinux

为什么要关闭呢？
那是因为在RedHat linux操作系统中默认开启了防火墙，SELinux也处于启动状态，一般状态为enforing。致使很多服务端口默认是关闭的。

[root@localhost home]# vim /etc/selinux/config
默认是SELINUX=enforcing设置为SELINUX=disabled
[root@localhost home]# setenforce 0   让配置文件生效

9.关闭防火墙,以免安装过程中发生不必要的错误

[root@localhost ~]# systemctl stop firewalld     防火墙暂时关闭
 
[root@localhost ~]# systemctl disable firewalld  防火墙永久关闭

10.安装oracle11g的依赖包

[root@localhost ~]# yum install gcc make binutils gcc-c++ compat-libstdc++-33elfutils-libelf-devel elfutils-libelf-devel-static ksh libaiolibaio-develnumactl-devel sysstat unixODBC unixODBC-devel pcre-devel –y

11.添加用户和组

[root@localhost ~]# groupadd oinstall		创建组名
 
[root@localhost ~]# groupadd dba           创建数据组
 
[root@localhost ~]# useradd -g oinstall -G dba oracle   创建oracle并放到oinstall组
 #####注意删除用户  需要userdel -r 用户名  ，否则 userdel 用户还需要 rm -rf /home/用户名
[root@localhost ~]# passwd oracle      设置oracle密码
 
[root@localhost ~]# id oracle			显示oracle的ID，以及所属群组的ID。

uid=1001(oracle) gid=1001(oinstall) groups=1001(oinstall),1002(dba)

12.修改内核参数配置文件

[root@localhost ~]# vim /etc/sysctl.conf


# For more information, see sysctl.conf(5) and sysctl.d(5).   下面添加
 
fs.aio-max-nr = 1048576
 
fs.file-max = 6815744
#所有共享内存段相加大小限制
kernel.shmall = 2097152    
#最大单个共享内存段大小(建议为内存一半), >9.2的版本已大幅降低共享内存的使用
kernel.shmmax = 536870912   
#一共能生成多少共享内存段，每个PG数据库集群至少2个共享内存段
kernel.shmmni = 4096         
#信号量
kernel.sem = 250 32000 100 128   
# 本地自动分配的TCP, UDP端口号范围
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

13.查看配置是否生效

[root@localhost home]# sysctl -p

fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
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

14.修改用户的限制文件

[root@localhost home]# vim /etc/security/limits.conf

#@student - maxlogins 4  在这个下面加
 #系统中最大可同时存在的进程数
oracle soft nproc 2047     
 
oracle hard nproc 16384
 
oracle soft nofile 1024
 
oracle hard nofile 65536
 
oracle soft stack 10240

15.修改用户验证选项（root用户）

[root@localhost home]# vim /etc/pam.d/login

#pam_selinux.so close should be the first session rule

session    required     /lib64/security/pam_limits.so
session    required     pam_limits.so

如图：在这里插入图片描述

16.创建oracle安装目录和设置文件权限

普及：https://www.runoob.com/linux/linux-comm-mkdir.html 有关linux命令

-p 确保目录名称存在，不存在的就建一个。

[root@localhost ~]# mkdir -p /data/oracle/product/11.2.0
 
[root@localhost ~]# mkdir /data/oracle/oradata
 
[root@localhost ~]# mkdir /data/oracle/inventory
 
[root@localhost ~]# mkdir /data/oracle/fast_recovery_area
 
[root@localhost ~]# chown -R oracle:oinstall /data/oracle
 
[root@localhost ~]# chmod -R 777 /data/oracle

17.切换为oracle用户,设置oracle用户环境变量

.bash_profile在/home/oracle/目录下

[root@localhost ~]# su - oracle
 
[oracle@localhost ~]$ vim .bash_profile

注意：不要把.bash_profile文件下原有的path和export PATH注释掉
PATH= P A T H : PATH: PATH:HOME/.local/bin:$HOME/bin
export PATH

#User specific environment and startup programs   这个下面添加
PATH=$PATH:$HOME/.local/bin:$HOME/bin
export PATH
在原有的下面添加
ORACLE_BASE=/data/oracle export ORACLE_BASE
 
ORACLE_HOME=$ORACLE_BASE/product/11.2.0 export ORACLE_HOME
 
NLS_LANG=AMERICAN_AMERICA.ZHS16GBK export NLS_LANG
 
ORACLE_SID=infodb export ORACLE_SID
 
PATH=$PATH:$ORACLE_HOME/bin:$ORACLE_HOME/jdk/bin:/sbin
 
export PATH
 
BIN=$ORACLE_HOME/bin export BIN
 
LD_LIBRARY_PATH=$ORACLE_HOME/lib export LD_LIBRARY_PATH
 
export LANG=en_US.UTF-8

注意，ORACLE_SID=infodb与创建的数据库实例名称一致，否则数据库启动后无法访问。

17.1 配置完后使用命令使配置生效

 [oracle@localhost ~]$ source .bash_profile
#使用echo $ORACLE_BASE或者echo $ORACLE_HOME#查看配置的信息是否生效，如果正确的话是和你的配置是一致的

17.2 退出在登录，使得环境变量的配置生效

[oracle@loaclhost ~]$ exit
[root@loaclhost ~]$ su - oracle
[oracle@loaclhost ~]$ env |grep ORA
 
ORACLE_SID=infodb
 
ORACLE_BASE=/data/oracle
 
ORACLE_HOME=/data/oracle/product/11.2.0

18. 安装前的最后准备–编辑静默安装响应文件

注：严格按照命令来
a. 将响应文件复制到oracle用户目录 即/home/oracle

[oracle@localhost ~]$ cp -R /home/database/response/ .
[oracle@localhost ~]$ ll
total 0
drwxr-xr-x. 2 oracle oinstall 61 Sep 24 09:00 response

b. 编辑相应文件

 [oracle@localhost ~]$ cd response/
 [oracle@localhost response]$ vim db_install.rsp

注：在这个文件db_install.rsp找对应的将等于号后面填了

oracle.install.option=INSTALL_DB_SWONLY
 
ORACLE_HOSTNAME=localhost
 
UNIX_GROUP_NAME=oinstall
 
INVENTORY_LOCATION=/data/oracle/inventory
 
SELECTED_LANGUAGES=en,zh_CN
 
ORACLE_HOME=/data/oracle/product/11.2.0
 
ORACLE_BASE=/data/oracle
 
oracle.install.db.InstallEdition=EE
 
oracle.install.db.DBA_GROUP=dba
 
oracle.install.db.OPER_GROUP=dba
 
DECLINE_SECURITY_UPDATES=true

19.根据响应文件静默安装Oracle11g

[oracle@localhost database]$ cd /home/database/
 
[oracle@localhost database]$ ./runInstaller -silent -responseFile /home/oracle/response/db_install.rsp -ignorePrereq

 ！！没反应的话耐心等会!!!!!

在这里插入图片描述

可以切换终端执行,切记!! 不要退出当前用户，从新打开一个窗口
执行tail -f /data/oracle/inventory/logs/installActions2015-06-08_04-00-25PM.log命令查看安装程序日志
如果当前用户的窗口出现以successfully Setup Software提示时，代表安装成功

19.1 安装成功后,按照要求执行脚本

[root@localhost ~]# sh /data/oracle/inventory/db_1/orainstRoot.sh
	注：如果没有db_1文件夹的话/data/oracle/inventory/orainstRoot.sh
 
[root@localhost ~]# sh /data/oracle/product/11.2.0/root.sh
Check /data/oracle/product/11.2.0/install/root_node130_2015-06-08_00-06-40.log for the output of root script

注意切换用户
在这里插入图片描述

20.静默方式配置监听(图形化、命令)

20.1 命令

切换oracle用户登录,命令安装

[oracle@localhost ~]$ su - oracle
[oracle@localhost ~]$  netca /silent /responseFile /home/oracle/response/netca.rsp

可能会报错

oracle is not in the sudoers file. This incident will bereported

oracle 用户不在sudoers组中， 切换成root用户 ， 执行命令：chmod u+w /etc/sudoers ， vim /etc/sudoers 这个目录，找到 root ALL=(ALL) ALL 这行，在这行下面添加 oracle ALL=(ALL) ALL ， chmod u-w /etc/sudoers 最后撤销权限
在这里插入图片描述

20.2 图形化

我的安装目录 cd /data/oracle/product/11.2.0
在这里插入图片描述
在这里插入图片描述

  • 成功运行后，在/data/oracle/product/11.2.0/db_1/network/admin/或/data/oracle/product/11.2.0/network/admin/中生成listener.ora和sqlnet.ora

20.3 通过netstat命令可以查看1521端口正在监听。

Yum安装netstat软件，软件包是在net-tools中。

[root@localhost ~]$ yum install net-tools
 
[root@localhost ~]$ netstat -tnulp | grep 1521
tcp6       0      0 :::1521                 :::*                    LISTEN      19955/tnslsnr

21.以静默方式建立新库，同时也建立一个对应的实例。

用oracle用户登录,再次进去响应文件夹

[oracle@localhost ~]$ vim /home/oracle/response/dbca.rsp

注：在这个文件dbca.rsp找对应的将等于号后面填了，并且默认为是注释掉的，把用到的不要注释
设置参数：

GDBNAME= “infodb”
 
SID =” infodb”
 
SYSPASSWORD= “ system@2017”
 
SYSTEMPASSWORD= “system@2017”
 
SYSMANPASSWORD= “ system@2017”
 
DBSNMPPASSWORD= “ system@2017”
 
DATAFILEDESTINATION=/data/oracle/oradata
 
RECOVERYAREADESTINATION=/data/oracle/fast_recovery_area
 
CHARACTERSET= “ZHS16GBK”
 
TOTALMEMORY= “819”

进行静默配置：

[oracle@localhost ~]$ dbca -silent -responseFile /home/oracle/response/dbca.rsp

在这里插入图片描述
查看监听状态(监听命令 启动监听：lsnrctl start、停止监听：lsnrctl stop、查看监听状态：lsnrctl status)
在这里插入图片描述
登录查看实例状态：

[oracle@localhost ~]$ sqlplus / as sysdba     #sysdba超级用户

SQL*Plus: Release 11.2.0.1.0 Production on Thu Sep 24 12:55:23 2020

Copyright (c) 1982, 2009, Oracle.  All rights reserved.

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> quit
Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production

[oracle@localhost ~]$

22.创建表空间(模式)、用户及授权

1、创建表空间
INITIAL_G 是表空间的名称，DATAFILE是创建数据库文件的路径，然后初始大小是200m，然后自动增加是500M，参数可以根据自己的需求来调整

SQL> CREATE TABLESPACE INITIAL_G                                                                                                                                          DATAFILE 'u01apporacleoradataINITIAL_G.dbf'                    
SIZE 200M AUTOEXTEND ON NEXT 500M 
MAXSIZE UNLIMITED LOGGING EXTENT MANAGEMENT 
LOCAL SEGMENT SPACE MANAGEMENT AUTO

在这里插入图片描述

2、创建用户 oracle是根据用户区分库的也就是表空间 INITIAL_G 表空间 infodb是数据库用户 by后的是密码

SQL> CREATE USER infodb IDENTIFIED BY infodb DEFAULT TABLESPACE INITIAL_G

User created.

注：如果过出现以下的话就是你没有加分号，oracle语法是非常严格的,加个分号自动退出

SQL>  CREATE USER infodb IDENTIFIED BY infodb DEFAULT TABLESPACE INITIAL_G
  2

3、授权（直接给了 dba权限）

SQL>  grant dba to infodb

Grant succeeded.

查询数据库用户名

select username, account_status, lock_date from dba_users

ACCOUNT_STATUS ：账户状态 open 启用
在这里插入图片描述

oracle的默认的用户名和密码
1.用户名:sys密码:change_on_install
2.用户名:system密码:manager
3.用户名:scott密码:tiger     普通用户

[oracle@localhost ~]$ sqlplus /nolog 无用户名登录

conn 用户名/密码 切换用户
可能会报错SP2-0306: Invalid option.
换成connect 命令

SQL> connect
Enter user-name: scott
Enter password: tiger

会提示过期，直接修改密码
在这里插入图片描述

如果多次进行密码输入错误，我记得是3次以上就把你这个用户账号锁住了

4、 解锁用户

alter user 用户名 account unlock

5、测试远程连接
在这里插入图片描述

23、设置开机启动

1、修改/data/oracle/product/11.2.0/bin/dbstart

[oracle@localhost~]$ vim /data/oracle/product/11.2.0/bin/dbstart

#将ORACLE_HOME_LISTNER=$1 修改为ORACLE_HOME_LISTNER=$ORACLE_HOME

在这里插入图片描述
2、修改/data/oracle/product/11.2.0/bin/dbshut

[oracle@localhost~]$ vim /data/oracle/product/11.2.0/bin/dbshut

将ORACLE_HOME_LISTNER=$1 修改为ORACLE_HOME_LISTNER=$ORACLE_HOME

在这里插入图片描述
3、修改/etc/oratab 文件

infodb:/data/oracle/product/11.2.0:N      `将 N 改为 Y `

4、创建启动文件

切换root用户 vim /etc/init.d/oracle 添加以下内容

#!/bin/sh  
# chkconfig: 345 61 61  
# description: Oracle 11g R2 AutoRun Servimces  
# /etc/init.d/oracle  
#  
# Run-level Startup script for the Oracle Instance, Listener, and  
# Web Interface  
export ORACLE_BASE=/data/oracle  
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0
export ORACLE_SID=infodb
export ORACLE_UNQNAME=$ORACLE_SID    
export PATH=$ORACLE_HOME/bin:/user/sbin:$PATH  
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH  
ORA_OWNR="oracle"  
# if the executables do not exist -- display error  
if [ ! -f $ORACLE_HOME/bin/dbstart -o ! -d $ORACLE_HOME ]  
then  
echo "Oracle startup: cannot start"  
exit 1  
fi  
# depending on parameter -- startup, shutdown, restart  
# of the instance and listener or usage display  
case "$1" in  
start)  
# Oracle listener and instance startup  
su $ORA_OWNR -lc $ORACLE_HOME/bin/dbstart  
echo "Oracle Start Succesful!OK."  
  
stop)  
# Oracle listener and instance shutdown  
su $ORA_OWNR -lc $ORACLE_HOME/bin/dbshut  
echo "Oracle Stop Succesful!OK."  
  
reload|restart)  
$0 stop  
$0 start  
  
*)  
echo $"Usage: `basename $0` {start|stop|reload|reload}"  
exit 1  
esac  
exit 0

5、设置启动文件权限

[root@localhost~]$ chmod +x oracle
[root@localhost~]$ chkconfig --add oracle 
[root@localhost~]$ chkconfig oracle on

6、 重启测试

[root@localhost~]$ reboot

7、查看状态、没有启动
在这里插入图片描述
执行启动监听命令
在这里插入图片描述修改hostname 和 hosts 为同样的

[root@localhost admin]# vim /etc/hostname

localhost

修改hosts

[root@localhost admin]# vim /etc/hosts

127.0.0.1   localhost
192.168.198.130 localhost

24、解决报错

1、执行了一边命令配置监听有执行了一遍图形化的

（这个原因可能是我在执行步骤20时，执行了一遍图形化和命令监听导致的)看到这个·Listener "LISTENER" already exists.，但是我监听的名字是infodb,然后我查看/home/oracle/response/netca.rsp文件，将文件中LISTENER_NAMES改为我的监听 infodb,重新执行监听netca /silent /responseFile /home/oracle/response/netca.rsp,启动 lsnrctl statrt

[oracle@oracle ~]$ netca /silent /responseFile /home/oracle/response/netca.rsp

Parsing command line arguments:
    Parameter "silent" = true
    Parameter "responsefile" = /home/oracle/response/netca.rsp
Done parsing command line arguments.
Oracle Net Services Configuration:
Profile configuration complete.
Listener "LISTENER" already exists.
Oracle Net Services configuration successful. The exit code is 0

TNS-01106: Listener using listener name LISTENER has already been started
[oracle@oracle ~]$ netstat -tnulp | grep 1521

2、异常关机（我是通过主动实现，因为我进去listener文件只有监听没有SID_LIST）

在这里插入图片描述

报错及解决思路：(该问题是由于缺少监听器的SID_LIST描述项引起的，采用netca进行配置的时候经常不会生成SID_LIST，导致连接出现问题)

Ora-12514：TNS：The listener is currently unable to recognize the service requested in the link descriptor

1、监听加载服务有主动和被动两种方式

主动是通过在listener.ora文件中添加代码来实现的。代码如下：

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = infodb) #根据自己的配置来
      (ORACLE_HOME = /data/oracle/product/11.2.0) #根据自己的配置来
      (GLOBAL_DBNAME = infodb) #根据自己的配置来
    )
    (SID_DESC =
        (GLOBAL_DBNAME = INITIALG)#根据自己的配置来
        (ORACLE_HOME = /data/oracle/product/11.2.0)#根据自己的配置来
        (SID_NAME = INITIALG)#根据自己的配置来
    )
  )

被动是由实例的pmon进程在listener中注册服务。
（解决办法：
1、把Oracle相关的服务关闭了；
在这里插入图片描述

lsnrctl stop

2、接着先启动监听服务（OracleOraDb11g_home1TNSListener）

lsnrctl start

3、后启动（OracleServiceORCL）可能会出现ORA-01034 - Oracle not available”和“ORA-27101 - shared memory realm does not exist”

SQL>sqlplus /nolog
SQL>connect / as sysdba
SQL>shutdown immediate
SQL> shutdown abort
SQL>sqlplus /nolog
SQL>connect / as sysdba
SQL>startup

下次就直接启动监听和oracleService就ok

卸载oracle11g
