Oracle数据库环境准备 |
|||
|
第一部分：安装oracle软件包 |
||||
|
1.安装 VMware Tools |
安装vmware-tools工具 步骤1、点击---->虚拟机----->安装Vmware Tools
步骤2、df -h [[email protected] ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 20G 8.3G 11G 45% / /dev/sda1 99M 12M 83M 12% /boot tmpfs 1.5G 0 1.5G 0% /dev/shm /dev/scd0 2.8G 2.8G 0 100% /media/Enterprise Linux dvd 20090908 步骤3、挂在VMwareTools镜像 mount /dev/scd0 /mnt/ df -h [[email protected] ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 20G 8.3G 11G 45% / /dev/sda1 99M 12M 83M 12% /boot tmpfs 1.5G 0 1.5G 0% /dev/shm /dev/scd0 2.8G 2.8G 0 100% /media/Enterprise Linux dvd 20090908 /dev/scd0 2.8G 2.8G 0 100% /mnt 步骤4、cp /mnt/VMwareTools… /etc/opt/ cd /opt/ ls 步骤5、解压VMwareTools包 tar -zxvf VMwareTools… cd vmware-tools-distrib ls 步骤6、./vmware-install.pl 一路回车 最后reboot一下 |
|||
|
2.配置ip地址 计算机名 配置主机 防火墙设置 |
1，配置IP地址 vim /etc/sysconfig/network-scripts/ifcfg-eth0
/etc/init.d/network restart chkconfig network on ifconfig eth0 2，配置计算机名字 vim /etc/sysconfig/network
修改临时主机名 hostname server253.oracle.com 3，配置主机 vim /etc/hosts
ping server253.oracle.com ping server253 4，防火墙设置 system-config-securitylevel
|
|||
| 3.配置yum仓 库 |
设备状态---->勾选上已连接 df -h mount /dev/scd0 /mnt/ vim /etc/yum.repos.d/server.repo [base] name=rhel5.4 baseurl=file:///mnt/Server enabled=1 gpgcheck=0 |
|||
|
4.检查软件的 必要性 |
Checking the Software Requirements
[[email protected] ~]rpm -qa|grep compat-db [[email protected] ~]# yum -y install compat-db [[email protected] ~]# rpm -qa|grep pdksh [[email protected] ~]# yum -y install pdksh [[email protected] ~]# rpm -qa|grep sysstat [[email protected] ~]# yum -y install sysstat |
|||
|
5.检查网络步 骤 |
1. ifconfig eth0
|
|||
|
6.配置名称解 析 |
vim /etc/hosts
ping server253.oracle.com ping server253 |
|||
|
7. 创建安装软 件需要账户 名和组 8. 判断nobody 是否存在 |
Creating Required Operating System Groups and Users 创建三个用户 [[email protected] ~]# useradd dba [[email protected] ~]# useradd oinstall [[email protected] ~]# useradd oper [[email protected] ~]# id oracle uid=500(oracle) gid=500(oracle) groups=500(oracle) 将用户加入到组 usermod -g oinstall -G oinstall,dba,oper,oracle oracle [[email protected] ~]# id oracle uid=500(oracle) gid=502(oinstall) groups=502(oinstall),500(oracle),501(dba),503(oper) 8,Verifying that the User nobody Exists 判断nobody是否存在 原因：外部作业必须存在nobody [[email protected] ~]# id nobody uid=99(nobody) gid=99(nobody) groups=99(nobody) |
|||
|
9. 内核参数 |
Configuring Kernel Parameters vi /etc/sysctl.conf
-shmall :该参数表示系统依次可以使用的共享内存段的总容量（以页为单位）。默认值是2097152，通常不需要修改 -shmmax:该参数定义了单个进程能够使用的共享内存段的最大尺寸（以字节为单位），默认为32MB，对于ORACLE来说，该默认值太低了，通常将其设置为2GB -shmmin:该内核参数用于设置系统范围内共享内存段的最大个数，该参数的默认值是4096，通常不需要更改 -sem:该参数表示设置的信号量 -file-max: 该参数表示文件句柄的最大数量，文件句柄设置表示在linux系统中可以打开的文件数量 [[email protected] ~]# sysctl -p |
|||
|
10. 配置SHELL 限制 |
配置SHELL限制 a,vim /etc/security/limits.conf
b,vi /etc/pam.d/login
c,Depending on the oracle user‘s default shell vi /etc/profile
|
|||
|
11. 创建所需 要的目录 |
创建所需要的目录 Identifying Required Software Directories a,Oracle Base Directory--- 根目录 必须手工创建 mkdir -p /u01/app/oracle b,Oracle Inventory Directory 名字：oracle_base/oraInventory --产品清单列表 /u01/app/oracle/oraInventory You do not need to create it. 安装自动创建 c,Oracle Home Directory 软件所安装的目录 每安装一个产品都会有一相应的oralce home目录，You do not need to create this directory. 建议你们创建 /u01/app/oracle/product/10.2.0/db_1 d,命令 # mkdir -p /u01/app/oracle # chown -R oracle:oinstall /u01/app/oracle # chmod -R 775 /u01/app/oracle 测试 ll /u01/app |
|||
|
12.配置oracle 用户环境 |
Configuring the oracle User‘s Environment su - oracle cd /home/oracle vim .bash_profile
[[email protected] ~]# source .bash_profile |
|||
|
13.准备安装介 质 |
a,如何将安装介质上传到linux b,tool c,使用root上传，使用解压，查看权限 unzip 包名 chown -R oracle:oinstall /u01 chmod -R 775 /u01 |
|||
|
14. su - oracle |
[[email protected] ~]$ su - root [[email protected] ~]# xhost + access control disabled, clients can connect from any host [[email protected] ~]# su - oracle [[email protected] ~]$ xclock
|
|||
|
15. 安装你的数据库软件 16.安装过程要 做的事情 |
[[email protected] ~]$ cd /u01/database/ [[email protected] database]$ ./runInstaller
a,vim /home/oracle/.base_profile
b,不要选默认创建数据库，这里只是安装数据库软件 c.最后以root身份执行2个脚本： orainstRoot.sh==用来更新最终的产品清单信息 root.sh ==根据当前主机的信息生成一些使用脚本，如dbca [[email protected] ~]$ source .bash_profile [[email protected] ~]$ cd /u01/database/ [[email protected] database]$ ./runInstaller
[[email protected] /]# /u01/app/oracle/oraInventory/orainstRoot.sh [[email protected] /]# /u01/app/oracle/product/10.2.0/db_1/root.sh
|
|||
|
第二部分：创建侦听 |
||||
|
[[email protected] ~]$ netca -bash: netca: command not found 查看netca所在的路径 [[email protected] bin]$ ls netca netca [[email protected] bin]$ pwd /u01/app/oracle/product/10.2.0/db_1/bin [[email protected] ~]$ vim .bash_profile
[[email protected] ~]$ source .bash_profile [[email protected] ~]$ netca
[[email protected] ~]$ lsnrctl status [[email protected] ~]$ netstat -tunlp |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.) tcp 0 0 0.0.0.0:1521 0.0.0.0:* LISTEN 14633/tnslsnr |
||||
|
第三部分：创建数据库 |
||||
|
------------创建数据库-----dbca-- 一是采用脚本的方式 二是采用图形界面 [[email protected] ~]$ dbca
使用DBCA创建第一个数据库：orcl 全局数据库名：数据库名+域名 oracle sid： 实例名 默认实例名和数据库名一样，也可以不一样
enterprise manager (EM) EM采用网页形式对数据库进行管理 有2种类型的EM： 一是采用GRID CONTROL-它可以管理多台主机以及多个数据库，必须在主机上安装agent 二是采用Database control 只能管理一个数据库 数据库管理方式 1 grid control 默认不可选，原因：你没有配置grid contol agent 2 dbconsole 管理
一定要选择此模板
|
||||
|
查看创建的数据库信息 [[email protected] orcl]$ ls adump bdump cdump dpdump pfile udump [[email protected] orcl]$ pwd /u01/app/oracle/admin/orcl cd admin/实例名/ 审计 跟踪 警告日志 [[email protected] admin]$ cd orcl/bdump/ [[email protected] bdump]$ ls alert_orcl.log orcl_lgwr_16683.trc orcl_lgwr_16778.trc orcl_lgwr_16845.trc cd /u01/app/oracle/oradata/实例名/ 数据库文件 这里十二个文件要写脚本 [[email protected] orcl]$ ls control01.ctl example01.dbf redo03.log temp01.dbf control02.ctl redo01.log sysaux01.dbf undotbs01.dbf control03.ctl redo02.log system01.dbf users01.dbf [[email protected] orcl]$ pwd /u01/app/oracle/oradata/orcl ps -elf |grep ora [[email protected] dbs]$ ps -elf|grep ora 0 S root 3548 3523 0 78 0 - 494 stext Aug13 ?

第四部分：oracle登录模式 |
||||
| 1.数据库的连 接方式介绍 |
oracle登录模式 连接基本使用
1、EM-企业化管理器（图形管理） 2、isqlplus--（JAVA） 3、sqlplus |
|||
| 2.sys账号登录 |
sqlplus账号/密码 as sysdba [[email protected] ~]$ sqlplus sys/oracle as sysdba SQL*Plus: Release 10.2.0.1.0 - Production on Mon Aug 14 06:27:25 2017 Copyright (c) 1982, 2005, Oracle. All rights reserved. Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production With the Partitioning, OLAP and Data Mining options SQL> |
|||
| 3.sys账户采 用的是系统 身份验证 |
例如： [[email protected] ~]$ sqlplus xiaoming/oracle as sysdba SQL*Plus: Release 10.2.0.1.0 - Production on Mon Aug 14 06:29:53 2017 Copyright (c) 1982, 2005, Oracle. All rights reserved. Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production With the Partitioning, OLAP and Data Mining options SQL> show user USER is "SYS" SQL> 所以系统账号还可以这样登录 [[email protected] ~]$ sqlplus / as sysdba SQL*Plus: Release 10.2.0.1.0 - Production on Mon Aug 14 06:31:08 2017 Copyright (c) 1982, 2005, Oracle. All rights reserved. Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production With the Partitioning, OLAP and Data Mining options SQL> 注：只要你的oracle账号可以登录到你的系统上面来，那么你的SQL就可以登录 |
|||
| 4.查看当前登 录的账号 |
SQL> show user USER is "SYS" |
|||
| 5.退出登录 |
SQL> exit Disconnected from Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production With the Partitioning, OLAP and Data Mining options [[email protected] ~]$ |
|||
| 6.普通账号的 登录 |
oracle数据库在创建的时候，提供三个账号： sys scott hr scott账号默认登录的时候，密码为tiger，但是登录时候发现账号被锁定了 [[email protected] ~]$ sqlplus scott/tiger SQL*Plus: Release 10.2.0.1.0 - Production on Mon Aug 14 06:44:42 2017 Copyright (c) 1982, 2005, Oracle. All rights reserved. ERROR: ORA-28000: the account is locked Enter user-name: |
|||
| 7.解锁普通账 号 |
[[email protected] ~]$ sqlplus / as sysdba SQL> show user USER is "SYS" SQL> alter user scott account unlock ; User altered. [[email protected] ~]$ sqlplus scott/tiger SQL*Plus: Release 10.2.0.1.0 - Production on Mon Aug 14 06:49:14 2017 Copyright (c) 1982, 2005, Oracle. All rights reserved. ERROR: ORA-28001: the password has expired Changing password for scott New password: Retype new password: Password changed Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production With the Partitioning, OLAP and Data Mining options SQL> show user USER is "SCOTT" SQL> |
|||
| 8.修改普通账 号密码 |
SQL> show user USER is "SCOTT" SQL> alter user scott identified by redhat; User altered. 注意：注意：用户自己本身也可以修改自己的密码，一般情况是不被允许的 |
|||
| 9.同时解锁和 修改密码 |
SQL> alter user scott account unlock identified by oracle; alter user scott account unlock identified by oracle * ERROR at line 1: ORA-01031: insufficient privileges SQL> show user; USER is "SYS" SQL> alter user scott account unlock identified by oracle; User altered. SQL> |
|||
| 10.解锁hr账 号 |
sqlplus / as sysdba; alter user hr account unlock identified by redhat; exit sqlplus hr/redhat; show user; |
|||
| 11.用户之间 的切换 |
----conn hr/redhat---- 切换到hr账号上面 ----conn / as sysdba-- 切换到sys账号上面 ---conn sys/oracle as sysdba---切换到sys账号上面 SQL> show user USER is "SYS" SQL> alter user hr account unlock identified by redhat; User altered. SQL> show user; USER is "SYS" SQL> conn scott/oracle Connected. SQL> show user; USER is "SCOTT" SQL> |
|||
| 12.帮助文件 |

---需要安装rlwrap包---- 因为是源码包，所以有点麻烦 .gz结尾的包 所以gunzip rlwrap-0.37.tar.gz rlwrap-0.37.tar tar -xvf rlwrap-0.37.tar 源代码安装其实是最简单的，不用搭建yum仓库 第一种方式：分两步解开 只要一步就可以解开带.gz的压缩包 tar -zxvf rlwrap-0.37.tar.gz vim REDEAME 查看安装说明 搜索 ：/INSTALL /INSTALL 源码包安装方式，需要两步，其实下面就合成了一步 ./configure; make install 需要root权限安装rlwrap-0.37.tar ./configure; make install 如果安装不成功需要检查这两个软件包是否有安装 ls |grep readline readline-5.1-3.el5.i386.rpm readline-devel-5.1-3.el5.i386.rpm rpm -qa|grep readline ls |grep libter libtermcap-2.0.8-46.1.i386.rpm libtermcap-devel-2.0.8-46.1.i386.rpm rpm -qa|grep libter ---------检验------------ su - oracle sqlplus / as sysdba; selecct * from tab; exit 发现报错，使用不了 因为rlwrap是安装在linux系统上面的，所以每次使用的时候都必须告诉oracle系统 rlwrap sqlplus / as sysdba; 现在发现是可以上翻看，下查看的 可以通过取别名来实现 alias sqlplus=‘rlwrap sqlplus‘ 不过这个是临时的 要想要永久的生效需要在oracle家目录下面配置.bash_profile文件 ls -a vim .bash_profile alias sqlplus=‘rlwrap sqlplus‘ 添加这一项即可 保存退出后source .bash_profile |
