centos7下使用x11远程带窗口安装Oracle

centos7静默安装oracle11gR2

文章目录

一、检查硬件要求

1、内存要求：

要求：内存最小1G，推荐2G或者更高。

#查看命令,下列是我的内存
[root@centos7-minimal opt]# grep MemTotal /proc/meminfo
MemTotal:         995924 kB

PS：还有其他硬件要求可以直接去官网(传送门)查看，这里不再叙述。

2、安装包：

• linux.x64_11gR2_database_1of2.zip

• linux.x64_11gR2_database_2of2.zip

  PS:官方下载地址：传送门；

  服务器无法访问互联网所需离线软件包

  https://pan.baidu.com/s/1JsCmtzGlv_QvLBVNxXkDmw

二、环境准备

1、安装必要的工具

#wget：下载工具；zip：打包工具；unzip：解压工具
[root@centos7-minimal ~]# yum -y install wget zip unzip xterm xorg-x11-xauth

• PS：如果已经有了就不需重复安装

2、关闭防火墙

#查看防火墙状态
[root@centos7-minimal ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled)
   Active: active (running) since 一 2019-03-04 14:31:15 CST; 4min 32s ago
     Docs: man:firewalld(1)
 Main PID: 693 (firewalld)
   CGroup: /system.slice/firewalld.service
           └─693 /usr/bin/python -Es /usr/sbin/firewalld --nofork --nopid

3月 04 14:31:15 localhost.localdomain systemd[1]: Started firewalld - dynamic firewall daemon.

#关闭防火墙
[root@centos7-minimal ~]# systemctl stop firewalld

#禁用防火墙
[root@centos7-minimal ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.

3月 04 14:36:35 centos7-minimal.micserver systemd[1]: Stopped firewalld - dynamic firewall daemon.

• PS：不关闭防火墙，远程连接会提示连接超时，也可以通过开放对应端口如下

firewall-cmd --permanent --zone=public --add-port=1521/tcp
firewall-cmd --reload
firewall-cmd --zone=public --list-ports

3、关闭Selinux

[root@centos7-minimal ~]# sed -i "s/SELINUX=enforcing/SELINUX=disabled/" /etc/selinux/config
[root@centos7-minimal ~]# setenforce 0
#查看Selinux状态
[root@centos7-minimal ~]# /usr/sbin/sestatus -v

4、安装Oracle依赖包

#通过安装Oracle YUM 源来安装所依赖的包
[root@centos7-minimal ~]# cd /etc/yum.repos.d 
[root@centos7-minimal yum.repos.d]# wget http://public-yum.oracle.com/public-yum-ol7.repo

#导入RPM-GPG-KEY-oracle
[root@centos7-minimal yum.repos.d]# wget http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol7 -O /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle

#安装oracle-rdbms-server-11gR2-preinstall快速配置Oracle安装环境
[root@centos7-minimal yum.repos.d]# yum install oracle-rdbms-server-11gR2-preinstall -y

#安装完后查看后台日志内容
[root@centos7-minimal yum.repos.d]# more /var/log/oracle-rdbms-server-11gR2-preinstall/results/orakernel.log

#离线安装方式
[root@centos7-minimal oracle-rdbms-server-11gR2-preinstall]# yum localinstall *.rpm

• PS：#oracle-rdbms-server-11gR2-preinstall包所干的事情

（1）自动安装oracle所需的RPM包
（2）自动创建oracle用户和group组
（3）自动配置/etc/sysctl.conf内核参数
（4）自动配置/etc/security/limits.conf参数

三、安装前配置

1、修改oracle用户密码

#修改oracl用户密码
[root@centos7-minimal oracle-rdbms-server-11gR2-preinstall]# passwd oracle
更改用户 oracle 的密码 。
新的 密码：
无效的密码： 密码少于 8 个字符
重新输入新的 密码：
passwd：所有的身份验证令牌已经成功更新。

2、用Oracle登录用户

#重新打开一个bash切换为Oracle用户登录系统
[oracle@centos7-minimal ~]$

3、上传安装包到服务器

#上传安装包到服务器
[oracle@centos7-minimal ~]$ ll
总用量 2295592
-rw-r--r-- 1 oracle oinstall 1239269270 9月  29 15:48 linux.x64_11gR2_database_1of2.zip
-rw-r--r-- 1 oracle oinstall 1111416131 9月  29 15:49 linux.x64_11gR2_database_2of2.zip

4、解压oracle安装包

#解压安装包
[oracle@centos7-minimal ~]$ unzip linux.x64_11gR2_database_1of2.zip
[oracle@centos7-minimal ~]$ unzip linux.x64_11gR2_database_2of2.zip
[oracle@centos7-minimal ~]$ ll
总用量 2295592
drwxr-xr-x 8 oracle oinstall        128 8月  21 2009 database
-rw-r--r-- 1 oracle oinstall 1239269270 9月  29 15:48 linux.x64_11gR2_database_1of2.zip
-rw-r--r-- 1 oracle oinstall 1111416131 9月  29 15:49 linux.x64_11gR2_database_2of2.zip
[oracle@centos7-minimal ~]$

5、配置oracle用户环境变量

#配置环境变量
[oracle@centos7-minimal ~]$ vim .bash_profile
#立即生效配置文件
[oracle@centos7-minimal ~]$ source .bash_profile
#增加
export ORACLE_BASE=/home/oracle/app/oracle
export ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_1
export ORACLE_SID=orcl
export PATH=$ORACLE_HOME/bin:$PATH
export LANG=en_US.utf8

四、开始安装

1、运行安装程序

#运行安装程序
[oracle@centos7-minimal ~]$ cd database/
[oracle@centos7-minimal database]$ ./runInstaller

默认路径即可

• 点击==next==

10、生成响应文件

• 有检测失败的==忽略==即可

• 勾选 ==ignore all==

• 可选保存==响应文件==

11、开始安装显示安装进度

12、如果安装过程中，在link binaries阶段出现2个错误

#第一个是关于ins_ctx.mk，log显示：
/lib64/libstdc++.so.5: undefined reference to `memcpy@GLIBC_2.14'

#原因据说是由于本机的glibc版本高于2.14（实际为2.17）。解决方法：
yum install glibc-static

#该软件包包含一个静态链接库：/usr/lib64/libc.a

#修改/home/oracle/app/oracle/product/11.2.0/dbhome_1/ctx/lib/ins_ctx.mk，
[root@centos7-minimal oracle-rdbms-server-11gR2-preinstall]# vim /home/oracle/app/oracle/product/11.2.0/dbhome_1/ctx/lib/ins_ctx.mk
#将

ctxhx: $(CTXHXOBJ)
       $(LINK_CTXHX) $(CTXHXOBJ) $(INSO_LINK)

#修改为：

ctxhx: $(CTXHXOBJ)
       -static $(LINK_CTXHX) $(CTXHXOBJ) $(INSO_LINK) /usr/lib64/stdc.a

#点击Retry即可。

#第二个错误是”Error in invoking target 'agent nmhs' of makefile'/app/oracle/product/11.2.0/db_1/sysman/lib/ins_emagent.mk.' 

#解决方法，在makefile中添加链接libnnz11库的参数：

#修改/home/oracle/app/oracle/product/11.2.0/dbhome_1/sysman/lib/ins_emagent.mk，
[root@centos7-minimal oracle-rdbms-server-11gR2-preinstall]# vim /home/oracle/app/oracle/product/11.2.0/dbhome_1/sysman/lib/ins_emagent.mk
#将

$(MK_EMAGENT_NMECTL)

#修改为：

$(MK_EMAGENT_NMECTL) -lnnz11

#点击Retry即可。

• 按上述修改完相关文件==retry==即可

• 继续安装

13、如果没有配置==hosts==会出现如下错误

#只需修改hosts文件retry即可
[root@centos7-minimal oracle-rdbms-server-11gR2-preinstall]# vim /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.131.7 centos7-minimal

• 继续安装

14、接下来会自动创建数据库

• 安装成功点击==ok==即可

• 接下来会出现要你使用root账户执行两个文件，新打开一个窗口登录root账户执行即可

15、最后点击finish即可

16、查看监听状态

#查看监听状态，监听安装完默认是启动的

五、安装及连接遇到的问题解决

ORA-12170:TNS:连接超时

查看linux系统的防火墙是否关闭，或者数据库端口是否开放
firewall-cmd --permanent --zone=public --add-port=1521/tcp
firewall-cmd --reload
firewall-cmd --zone=public --list-ports

ORA-12514 TNS 监听程序当前无法识别连接描述符中请求服务

PS：一步都不要少，其实对于修改的这两个文件内容，我猜在配置应答文件的时候配错了，应该直接将我们修改的这些在配置应答文件就配置到对应的地方，不过没有实验，我也是按照别人的博文一步一步来，怕出错不知道怎么修改，到此本地window可以连接数据库了。

• TNS-01190: The user is not authorized to execute the requested listener command

在执行lsnrctl stop 命令时，提示没有权限操作监听服务，原因时当前用户不是启动监听的用户，切换到启动监听服务的用户下执行lsnrctl stop 命令就可以了，因为启动监听服务的用户拥有所有权，其他用户不能操作

• 执行lsnrctl stop或者lsnrctl stop，提示lsnrctl: 未找到命令

切换到oracle用户的时候执行的是 su oracle，正确的是su - oracle

• ORA-01031: insufficient privileges

执行shellplus / as sysdba命令时提示该错误，可以先先切换到别的用户环境下，再切换回来试试。

• 本地window连接没有问题，但是其他人无法连接

检查以下是否能ping通，网络用桥接模式，不然别人ping不通，我用的是NAT模式，导致只能本地连接，别人连接不了我虚拟机的数据库。这种模式下如何ping通我没有查。

• ora-01950:对表空间XXX无权限

在创建表的时候，插入数据提示无权限

#username 换成没有权限的用户
grant  resource to username

六、设置数据库自启动

1、使用Oracle用户修改两个文件

vim $ORACLE_HOME/bin/dbstart
ORACLE_HOME_LISTNER=$1
#修改为：
ORACLE_HOME_LISTNER=$ORACLE_HOME
vim $ORACLE_HOME/bin/dbshut
ORACLE_HOME_LISTNER=$1
#修改为：
ORACLE_HOME_LISTNER=$ORACLE_HOME

2、修改/etc/oratab文件

[oracle@centos7-minimal ~]# vi /etc/oratab
找到：    orcl:/home/oracle/app/oracle/product/11.2.0/dbhome_1:N   
修改为：  orcl:/home/oracle/app/oracle/product/11.2.0/dbhome_1:Y

3、新建Oracle服务自启动脚本

[oracle@centos7-minimal ~]# vi /etc/init.d/oracle

• 将以下脚本复制到文件中，保存退出

#!/bin/sh

# chkconfig: 2345 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=/home/oracle/app/oracle #根据个人情况修改路径
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
export ORACLE_SID=orcl #改成自己的ORACLE_SID:testsid
export PATH=$PATH:$ORACLE_HOME/bin
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|restart|reload}"
exit 1
esac
exit 0

4、更改oracle脚本的执行权限

    [root@localhost oracle]# chmod a+x /etc/init.d/oracle

5、检查脚本能否执行

    [root@localhost oracle]# /etc/init.d/oracle start            #启动oracle脚本
    [root@localhost oracle]# /etc/init.d/oracle stop             #关闭oracle脚本
    [root@localhost oracle]# /etc/init.d/oracle restart          #重启oracle脚本

6、添加执行权限并建立链接

建立链接将启动脚本添加到系统服务并设置自启动

    [root@localhost oracle]# chkconfig --add oracle
    #ps 找不到命令的系统请安装chkconfig
    yum install chkconfig

ps:当这个命令被执行的时候，会去脚本文件oracle中寻找# chkconfig: 2345 61 61这行注释，并解析这行注释，根据解析结果分别在

/etc/rc.d/rc2.d
/etc/rc.d/rc3.d
/etc/rc.d/rc4.d
/etc/rc.d/rc5.d

中创建符号连接文件S61oracle，此文件在系统启动时根据运行级别执行，此文件是指向/etc/init.d/oracle文件。启动时系统向此文件发送一个start参数，执行oracle文件中的start分支。另外还会在

/etc/rc.d/rc0.d
/etc/rc.d/rc1.d
/etc/rc.d/rc6.d

中创建符号连接文件K61oracle，此文件在系统关闭时执行，此文件也指向/etc/init.d/oracle文件，关闭时系统向此文件发送一个stop参数，执行oracle文件中的stop分支。

chkconfig: 2345 61 61

表明脚本应该在运行级 2, 3, 4, 5 启动，启动优先权为61，停止优先权为 61。

修改服务运行等级(虽然脚本里写过，但还是重新设置一下)，可以自行设置oracle脚本的运行级别

root@localhost oracle]# chkconfig --level 2345 oracle on

说明：设置oracle脚本在运行级别为2、3、4、5时，都是on（开启）状态，off为关闭

7、查看oracle自动启动设置

[root@localhost oracle]# chkconfig --list oracle
oracle          0:关    1:关    2:开    3:开    4:开    5:开    6:关
#等级0表示：表示关机
#等级1表示：单用户模式
#等级2表示：无网络连接的多用户命令行模式
#等级3表示：有网络连接的多用户命令行模式
#等级4表示：不可用
#等级5表示：带图形界面的多用户模式
#等级6表示：重新启动

8、手动创建符号链接文件

• （执行效果和执行chkconfig --add oracle是一样，作为知识笔记记录，可以不执行）

[root@localhost oracle]# ln –s /etc/rc.d/init.d/oracle /etc/rc0.d/K61oracle
[root@localhost oracle]# ln –s /etc/rc.d/init.d/oracle /etc/rc1.d/K61oracle
[root@localhost oracle]# ln –s /etc/rc.d/init.d/oracle /etc/rc2.d/S61oracle
[root@localhost oracle]# ln –s /etc/rc.d/init.d/oracle /etc/rc3.d/S61oracle
[root@localhost oracle]# ln –s /etc/rc.d/init.d/oracle /etc/rc4.d/S61oracle
[root@localhost oracle]# ln –s /etc/rc.d/init.d/oracle /etc/rc5.d/S61oracle
[root@localhost oracle]# ln –s /etc/rc.d/init.d/oracle /etc/rc6.d/K61oracle

9、oracle的启动或关闭管理

#启动
[root@localhost oracle]# service oracle start
#停止
[root@localhost oracle]# service oracle stop
#重启
[root@localhost oracle]# service oracle restart

七、数据库字符集修改

PS:没有操作过，从参考文档摘过来的

注意事项：修改字符集前先将数据库进行备份

此处演示将ZHS16GBK字符集修改为AL32UTF8

1、修改server端字符集

登录shellpus查看字符集设置

[oracle@localhost ~]$ shellplus /nolog
shell*Plus: Release 11.2.0.1.0 Production on Wed Jan 24 13:55:51 2018
Copyright (c) 1982, 2009, Oracle.  All rights reserved.
shell> conn /as sysdba
Connected to an idle instance.                  #数据库未启动，先启动数据库。最好将数据库设未开机启动
shell> startup
shell> conn /as sysdba
Connected.                                      #连接成功
shell> select userenv('language') from dual;      #server端字符集查询


USERENV('LANGUAGE')
----------------------------------------------------
AMERICAN_AMERICA.ZHS16GBK

依次执行如下命令

shell>SHUTDOWN IMMEDIATE;
shell>STARTUP MOUNT;
shell>ALTER SYSTEM ENABLE RESTRICTED SESSION;
shell>ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
shell>ALTER SYSTEM SET AQ_TM_PROCESSES=0;
shell>ALTER DATABASE OPEN;
shell>ALTER DATABASE CHARACTER SET INTERNAL_USE AL32UTF8;
shell>SHUTDOWN IMMEDIATE;
shell>STARTUP;

shell> select userenv('language') from dual;
USERENV('LANGUAGE')
----------------------------------------------------
AMERICAN_AMERICA.AL32UTF8
shell> 

2、修改client端字符集

查看系统环境变量设置的字符集(client端字符集)

[oracle@localhost ~]$ cat /home/oracle/.bash_profile
...
PATH=$PATH:$HOME/.local/bin:$HOME/bin
export PATH

export ORACLE_BASE=/usr/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
export ORACLE_SID=orcl
export ORACLE_TERM=xterm
export PATH=$ORACLE_HOME/bin:/usr/sbin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export LANG=C
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK                #客户端字符集

进入编辑界面，将ZHS16GBK改为AL32UTF8，保存退出
[oracle@localhost ~]$ vim /home/oracle/.bash_profile
使配置生效
[oracle@localhost ~]$ source /home/oracle/.bash_profile
