主题： | 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 [root@server253 ~]# 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 [root@server253 ~]# 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
[root@server253 ~]rpm -qa|grep compat-db [root@server253 ~]# yum -y install compat-db
[root@server253 ~]# rpm -qa|grep pdksh [root@server253 ~]# yum -y install pdksh
[root@server253 ~]# rpm -qa|grep sysstat [root@server253 ~]# 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 [root@server253 ~]# useradd dba [root@server253 ~]# useradd oinstall [root@server253 ~]# useradd oper
[root@server253 ~]# 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 [root@server253 ~]# 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
[root@server253 ~]# 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
[root@server253 ~]# 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
[root@server253 ~]# 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 | [oracle@server253 ~]$ su - root [root@server253 ~]# xhost + access control disabled, clients can connect from any host
[root@server253 ~]# su - oracle [oracle@server253 ~]$ xclock
| |||
15. 安装你的数据库软件
16.安装过程要 做的事情
| [oracle@server253 ~]$ cd /u01/database/ [oracle@server253 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
[oracle@server253 ~]$ source .bash_profile [oracle@server253 ~]$ cd /u01/database/ [oracle@server253 database]$ ./runInstaller
[root@localhost /]# /u01/app/oracle/oraInventory/orainstRoot.sh [root@localhost /]# /u01/app/oracle/product/10.2.0/db_1/root.sh
| |||
第二部分：创建侦听 | ||||
[oracle@server253 ~]$ netca -bash: netca: command not found
查看netca所在的路径 [oracle@server253 bin]$ ls netca netca [oracle@server253 bin]$ pwd /u01/app/oracle/product/10.2.0/db_1/bin
[oracle@server253 ~]$ vim .bash_profile
[oracle@server253 ~]$ source .bash_profile
[oracle@server253 ~]$ netca
[oracle@server253 ~]$ lsnrctl status [oracle@server253 ~]$ 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 [oracle@server253 ~]$ 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 [oracle@server253 orcl]$ ls adump bdump cdump dpdump pfile udump [oracle@server253 orcl]$ pwd /u01/app/oracle/admin/orcl
cd admin/实例名/ 审计 跟踪 警告日志 [oracle@server253 admin]$ cd orcl/bdump/ [oracle@server253 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 [oracle@server253 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 [oracle@server253 orcl]$ pwd /u01/app/oracle/oradata/orcl ps -elf |grep ora [oracle@server253 dbs]$ ps -elf|grep ora 0 S root 3548 3523 0 78 0 - 494 stext Aug13 ?

| 13.启用历史 记录功能 | ---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 | |||
