Linux下安装Oracle 11


此为参照CU论坛上的高人写的文章并结合自身环境增加了点细节性的东西

操作系统 CentOS 4.2 2.6.11.8内核

安装准备

下载Oracle11安装包
内存最少1G
硬盘空间最6G
交换分区最少1024M，如果不够就用dd命令扩容一个如:

dd if=/dev/zero of=/.swap bs=1k count=1024000     创建文件
chmod 600 /.swap                               设置权限
mkswap /.swap                                  设定文件
swapon /.swap                                  生效文件

安装如下软件

binutils-2.17.50.0.6-2.el5
compat-libstdc++-33-3.2.3-61
elfutils-libelf-0.125-3.el5
elfutils-libelf-devel-0.125
glibc-2.5-12
glibc-common-2.5-12
glibc-devel-2.5-12
gcc-4.1.1-52
gcc-c++-4.1.1-52
libaio-0.3.106
libaio-devel-0.3.106
libgcc-4.1.1-52
libstdc++-4.1.1
libstdc++-devel-4.1.1-52.e15
make-3.81-1.1
sysstat-7.0.0
unixODBC-2.2.11
unixODBC-devel-2.2.11

做个链接（老版本要，Oracle11不要)
ln -s /usr/lib/libstdc++.so.6.0.3 /usr/lib/libstdc++.so.5

在sysctl.conf文件中加入下列:

kernel.shmall = 2097152
kernel.shmmax = 2147483648 -- (以字节为单位，物理内存数量*1024*1024*2， 为内存的2倍)
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default=8388608
net.core.rmem_max=8388608
net.core.wmem_default=262144
net.core.wmem_max=262144
保存退出
sysctl -p使其生效

设置Shell Limits(系统资源限制),提高软件的运行效率

在/etc/security/limits.conf文件中加入下列红色行：

oracle soft nofile 65536
oracle hard nofile 65536
oracle soft nproc 16384
oracle hard nproc 16384

在/etc/pam.d/login文件中加入下列行，如果里面没有的话：

session required /lib/security/pam_limits.so
session required pam_limits.so

在/etc/profile后加入以下语句:

vi /etc/profile
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi


创建dba/oper/oinstall组


/usr/sbin/groupadd dba
/usr/sbin/groupadd oper
/usr/sbin/groupadd oinstall

--创建oracle用户并设置用户所属组


/usr/sbin/usermod -g oinstall -G dba oracle
/usr/sbin/useradd -g oinstall -G dba oracle
passwd oracle
# id oracle
uid=501(oracle) gid=501(oinstall) groups=501(oinstall),502(dba)


--创建相关安装目录


mkdir -p /opt/oracle/product
mkdir -p /opt/oracle/product/OraHome
mkdir -p /opt/oraInventory                      #(the default inventory folder)
mkdir -p /opt/oracle/oradata                   #(change the right file owner)
mkdir -p /var/opt/oracle


--设置目录所有者和权限

chown -R oracle.oinstall /opt/oracle
chown -R oracle.oinstall /opt/oracle/oradata
chown -R oracle.oinstall /opt/oracle/product/OraHome
chown -R oracle.dba /opt/oraInventory
chown oracle.dba /var/opt/oracle
chmod -R 775 /opt/oracle
chmod -R 755 /var/opt/oracle


设置安装环境变量
# su - oracle --su到oracle用户下，
更改用户的一些配置
$vi /home/oracle/.bash_profile
添加以下参数，主要是配置oracle软件运环境参数
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
       . ~/.bashrc
fi

export ORACLE_BASE=/opt/oracle
export ORACLE_HOME=$ORACLE_BASE/product/OraHome
export ORACLE_SID=orcl
export ORACLE_OWNER=oracle
export ORACLE_TERM=vt100
export PATH=$PATH:$ORACLE_HOME/bin:$HOME/bin
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/Apache/Apache/bin:$PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib:/usr/local/lib
export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
CLASSPATH=$CLASSPATH:$ORACLE_HOME/network/jlib
export CLASSPATH
PATH=$PATH:/usr/sbin; export PATH
PATH=$PATH:/usr/bin; export PATH


注意：

11g:ORA_NLS33=$ORACLE_HOME/nls/admin/data
10g：ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data
9i：ORA_NLS33=/oracle/app/ora92/ocommon/nls/admin/data

保存退出
--执行以下命令让配置马上生效或以oracle用户登录使设置生效
$ source $HOME/.bash_profile

安装Oracle

首先要进入X界面
然后unzip解压压缩包
再进入目录下执行
./runInstaller

_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

( 配置这一步 出错了... )
安装过程和Windows下安装软件一样根据提示下一步下一步安装
在前几步会提示要检测你的系统硬件和软件是否达标，如果有不合规格的会提示报错要求改正
根据提示信息，将所有设置都设置好，所缺软件都装好，就可以了


[oracle@localhost database]$ ./runInstaller

Some requirement checks failed. You must fulfill these requirements before

continuing with the installation,at which time they will be rechecked.

Preparing to launch Oracle Universal Installer from /tmp/OraInstall2009-02-15_06-12-44AM. Please wait ...
DISPLAY not set. Please set the DISPLAY and try again.
Depending on the Unix Shell, you can use one of the following commands as examples to set the DISPLAY environment variable:
- For csh:                      % setenv DISPLAY 192.168.1.128:0.0
- For sh, ksh and bash:         $ DISPLAY=192.168.1.128:0.0; export DISPLAY
Use the following command to see what shell is being used:
        echo $SHELL
Use the following command to view the current DISPLAY environment variable setting:
        echo $DISPLAY
- Make sure that client users are authorized to connect to the X Server.
To enable client users to access the X Server, open an xterm, dtterm or xconsole as the user that started the session and type the following command:
% xhost +
To test that the DISPLAY environment variable is set correctly, run a X11 based program that comes with the native operating system such as 'xclock':
        % <full path to xclock.. see below>
If you are not able to run xclock successfully, please refer to your PC-X Server or OS vendor for further assistance.
Typical path for xclock: /usr/X11R6/bin/xclock
[oracle@localhost database]$

不过有时候装好了它也会定在那个地方不走了
在确定好所有的设置正确和软件都装好了
可以用./runInstaller -ignoreSysPrereqs跳过检测
注意，安装过程中，尽量不要去更改SID，把默认的SID和一些其它信息记录下来，可以省去后面的很多麻烦

安装完毕后，以root身份进入系统 运行
ORACLE_HOME下面的root.sh
完成最后的安装


Oracle的启动设置

确定/etc/oratab文件设置每个实例的重启标志为“Y”：
vim /etc/oratab 
orcl:/opt/oracle/product/OraHome:Y

打开ORACLE_HOME/network/admin/sqlnet.ora添加：

SQLNET.AUTHENTICATION_SERVICE=(NTS)

关闭selinux

启动EM控制台

su -oracle
ORACLE_HOME/bin/emctl start dbconsole (就可以访问https://localhost:1158/em的企业控制台)
ORACLE_HOME/bin/lsnrctl start
ORACLE_HOME/bin/dbstart

Oracle 常用操作命令


1、su – oracle 不是必需，适合于没有DBA密码时使用，可以不用密码来进入sqlplus界面。

2、sqlplus /nolog 或sqlplus system/manager 或./sqlplus system/manager@ora9i;

3、SQL>connect / as sysdba ;（as sysoper）或connect internal/oracle AS SYSDBA ;(scott/tiger) conn sys/change_on_install as sysdba;

4、SQL>startup; 启动数据库实例

5、 查看当前的所有数据库: select * from v$database;

select name from v$database;

desc v$databases; 查看数据库结构字段

7、怎样查看哪些用户拥有SYSDBA、SYSOPER权限:

SQL>select * from V_$PWFILE_USERS;

Show user;查看当前数据库连接用户

8、进入test数据库：database test;

9、查看所有的数据库实例：select * from v$instance；

如：ora9i

10、查看当前库的所有数据表：

SQL> select TABLE_NAME from all_tables;

select * from all_tables;

SQL> select table_name from all_tables where table_name like ‘u’;

TABLE_NAME———————————————default_auditing_options

11、查看表结构：desc all_tables;

12、显示CQI.T_BBS_XUSER的所有字段结构：

desc CQI.T_BBS_XUSER;

13、获得CQI.T_BBS_XUSER表中的记录：

select * from CQI.T_BBS_XUSER;

14、增加数据库用户：(test11/test)

create user test11 identified by test default tablespace users Temporary TABLESPACE Temp;

15、用户授权:
grant connect,resource,dba to test11;

grant sysdba to test11;

commit;
16、更改数据库用户的密码：(将sys与system的密码改为test.)

alter user sys indentified by test;

alter user system indentified by test;
