Oracle 11g 单实例安装文档

这里介绍在Red Hat Enterprise Linux Server release 5.7 (Tikanga)下安装ORACLE 11.2.0.1.0的过程，本文仅仅是为了写这样安装指导文档而整理在此。仅供参考！

1：下载对应平台的ORACLE 11g安装介质

安装ORACLE，首先要获取安装介质，大部分情况手头都有相关版本的安装介质。如果你手头没有安装介质，那么可以从下面链接获取对应平台的ORACLE安装介质。

http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html

强烈建议在安装ORACLE之前，先看一遍Linux Installation Guides 文档，毕竟这是最权威、最全面的资料。这样可以避免你在安装过程中遇到各类奇奇怪怪的问题，下载链接如下所示：

http://docs.oracle.com/cd/E11882_01/nav/portal_11.htm

2：检查硬件配置是否满足要求

2.1：内存大小要求

官方文档中，要求物理内存至少需要1G，推荐2G或以上配置，如果是服务器的话，配置肯定比这个高。查看系统内存配置，可以使用下面命令：

检查物理内存

[root@DB-Server ~]# grep MemTotal /proc/meminfo

MemTotal:      3968144 kB

[root@DB-Server ~]# free -m

             total       used       free     shared    buffers     cached

Mem:          3875        710       3164          0         85        317

-/+ buffers/cache:        307       3567

Swap:         5887          0       5887

[root@DB-Server ~]#

Note: On Linux, the HugePages feature allocates non-swappable memory for large page tables using memory-mapped files. If you enable HugePages, then you should deduct the memory allocated to HugePages from the available RAM before calculating swap space

Linux Swap大小要求（这是一个指导值，最好根据Linux版本供应商的文档设置。如果不太清楚这些，尽量按照下面要求设置）

检查交换空间（Swap）大小（free命令亦可）

[root@DB-Server ~]# grep SwapTotal /proc/meminfo

SwapTotal: 6029304 kB

Automatic Memory Management

从Oracle Database 11g开始，自动内存管理（Automatic Memory Management）要求更多的共享内存（/dev/shm）和文件描述符（file descriptors），共享内存的大小应该只是比MEMROY_MAX_TARGET 和MEMROY_TARGET大。

查看共享内存大小

[root@DB-Server ~]# df -h /dev/shm

Filesystem            Size  Used Avail Use% Mounted on

tmpfs                 1.9G  927M 1012M  48% /dev/shm

[root@DB-Server ~]#

Starting with Oracle Database 11g, the Automatic Memory Management feature requires more shared memory (/dev/shm)and file descriptors. The size of the shared memory must be at least the greater of the MEMORY_MAX_TARGET and MEMORY_TARGET parameters for each Oracle instance on the computer. If the MEMORY_MAX_TARGET parameter or the MEMORY_TARGET parameter is set to a nonzero value, and an incorrect size is assigned to the shared memory, it results in an ORA-00845 error at startup. On Linux systems, if the operating system /dev/shm mount size is too small for the Oracle system global area (SGA) and program global area (PGA), it results in an ORA-00845 error.

The number of file descriptors for each Oracle instance must be at least 512*PROCESSES. The limit of descriptors for each process must be at least 512. If file descriptors are not sized correctly, you see an ORA-27123 error from various Oracle processes and potentially Linux Error EMFILE (Too many open files)in non-Oracle processes.

注意：MEMORY_MAX_TARGET and MEMORY_TARGET cannot be used when LOCK_SGA is enabled or with HugePages on Linux.

2.2：系统架构要求

检查系统架构是否符合软件安装要求。如果是x86的架构，肯定不能运行64位的ORACLE软件。检查系统架构使用下面命令：

[root@DB-Server ~]# uname -m

x86_64

2.3：磁盘空间要求

At least 1 GB of disk space in the /tmp directory

检查/tmp目录大小

#df -h /tmp

检查磁盘空间：

#df –h

3：Checking the Software Requirements

[root@DB-Server Server]#

4 Configuring Kernel Parameters and Resource Limits

在修改内核参数前，我们先检查、查看这些内核参数的配置值

[root@DB-Server ~]# /sbin/sysctl -a | grep sem

kernel.sem = 250        32000   32      128

[root@DB-Server ~]# /sbin/sysctl -a | grep shm

vm.hugetlb_shm_group = 0

kernel.shmmni = 4096

kernel.shmall = 4294967296

kernel.shmmax = 68719476736

[root@DB-Server ~]# /sbin/sysctl -a | grep file-max

fs.file-max = 358778

[root@DB-Server ~]# /sbin/sysctl -a | grep ip_local_port_range

net.ipv4.ip_local_port_range = 32768    61000

[root@DB-Server ~]# /sbin/sysctl -a | grep rmem_default

net.core.rmem_default = 129024

[root@DB-Server ~]# /sbin/sysctl -a | grep rmem_max

net.core.rmem_max = 131071

[root@DB-Server ~]# /sbin/sysctl -a | grep wmem_default

net.core.wmem_default = 129024

[root@DB-Server ~]# /sbin/sysctl -a | grep wmem_max

net.core.wmem_max = 131071

[root@DB-Server ~]#

官方文档关于内核参数的推荐值如下截图所示，如果系统里面的配置大于这个值，那么就使用默认的值，不需要修改该参数值。

注意：If the current value of any parameter is higher than the value listed in this table, then do not change the value of that parameter.

在 /etc/sysctl.conf中添加如下参数的设置值，如果这一步设置有误，也没有关系，后面安装过程会检测系统参数，提示参数设置有误，不能通过。需要你重新配置。

fs.file-max = 6815744

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048576

fs.aio-max-nr = 1048576

net.ipv4.ip_local_port_range = 9000    65500

kernel.sem = 250        32000   100      128

设置完成后执行/sbin/sysctl -p 使之理解生效，从而不用重启系统。Oracle 11g新增了fixup脚本，在安装过程中，安装程序将会检查推荐的操作系统内核参数设置以及必须的软件包，对于不符合要求的部分将会自动生成runfixup.sh，只需要手动以root用户执行该脚本即可，不需要手动调整配置了。所以这一块即使一些内核参数配置不正确，也可以在后面环境快速处理、验证。

5：创建系统账号和用户组

一般要检查是否存在oracle以及dba、oinstall用户组，如果是新环境，可以直接跳过，如果以前安装过Oracle数据库，那么就必须检查一下。

[root@DB-Server ~]# more /etc/oraInst.loc

/etc/oraInst.loc: No such file or directory

[root@DB-Server ~]# grep oinstall /etc/group

[root@DB-Server ~]# grep dba /etc/group

[root@DB-Server ~]#

创建用户组dba、oinstall

# /usr/sbin/groupadd oinstall

# /usr/sbin/groupadd dba

创建用户oracle

[root@DB-Server ~]# id oracle

id: oracle: No such user

[root@DB-Server ~]# /usr/sbin/useradd -g oinstall -G dba oracle

[root@DB-Server ~]# id oracle

uid=500(oracle) gid=500(oinstall) groups=500(oinstall),501(dba) context=root:system_r:unconfined_t:SystemLow-SystemHigh

[root@DB-Server ~]#

设置账号密码：

[root@DB-Server ~]# passwd oracle

Changing password for user oracle.

New UNIX password:

BAD PASSWORD: it is too simplistic/systematic

Retype new UNIX password:

passwd: all authentication tokens updated successfully.

[root@DB-Server ~]#

6：修改用户资源限制

[root@DB-Server ~]# ulimit -Sn

[root@DB-Server ~]# ulimit -Hn

[root@DB-Server ~]# ulimit -Su

[root@DB-Server ~]# ulimit -Hu

[root@DB-Server ~]# ulimit -Ss

[root@DB-Server ~]# ulimit -Hs

unlimited

[root@DB-Server ~]#

在配置文件/etc/security/limits.conf 里面设置

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

修改用户验证选项

在/etc/pam.d/login配置文件里面加上下面配置，如果已经存在的，就忽略这些。

session required pam_selinux.so

session required /lib/security/pam_limits.so

7：修改用户配置文件

root用户下：修改/etc/profile文件加入如下参数

if [ $USER = "oracle" ]; then

        if [ $SHELL = "/bin/ksh" ]; then

              ulimit -p 16384

              ulimit -n 65536

        else

              ulimit -u 16384 -n 65536

fi

fi

或是在oracle用户下，修改.bash_profile

if [ $USER = "oracle" ]; then

  if [ $SHELL = "/bin/ksh" ]; then

       ulimit -p 16384

       ulimit -n 65536

  else

       ulimit -u 16384 -n 65536

fi

fi

8：安装目录配置

[root@DB-Server ~]# mkdir -p /u01/app/oracle

[root@DB-Server ~]# chown -R oracle:oinstall /u01/app/oracle

[root@DB-Server ~]# chmod -R 775 /u01/app/oracle

[root@DB-Server ~]# mkdir -p /u01/app/oraInventory

[root@DB-Server ~]# chown -R oracle:oinstall /u01/app/oraInventory/

[root@DB-Server ~]# chmod -R 775 /u01/app/oraInventory/

[root@DB-Server ~]#

9：修改用户bash shell

以oracle账号登录，修改.bash_profile参数文件

[oracle@DB-Server ~]$ vi .bash_profile

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.1.0/dbhome_1

export ORACLE_SID=gsp

export PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin

10：配置VNC

[root@DB-Server ~]# rpm -qa | grep vnc

vnc-server-4.1.2-14.el5_6.6

[root@DB-Server ~]# vi /etc/sysconfig/vncservers

VNCSERVERS="1:root"

VNCSERVERARGS[1]="-geometry 800x600 -nolisten tcp -nohttpd -localhost"

VNCSERVERS="2:oracle"

VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -nohttpd -localhost"

[root@DB-Server ~]# su - oracle

[oracle@DB-Server ~]$ vncserver :2

You will require a password to access your desktops.

Password:

Verify:

xauth:  creating new authority file /home/oracle/.Xauthority

xauth: (stdin):1:  bad display name "DB-Server.localdomain:2" in "add" command

New 'DB-Server.localdomain:2 (oracle)' desktop is DB-Server.localdomain:2

Creating default startup script /home/oracle/.vnc/xstartup

Starting applications specified in /home/oracle/.vnc/xstartup

Log file is /home/oracle/.vnc/DB-Server.localdomain:2.log

在root用户下，设置iptables，添加

-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 5901 -j ACCEPT

-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 5902 -j ACCEPT

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 1521 -j ACCEPT

ORACLE 11g图形化安装步骤

将安装介质解压到/tmp/database下，然后按照下面步骤安装

$ ./runInstaller

如果没有Oracle Support账号或不想设置，取消勾选选项。

勾选Server Class

我们勾选“Advanced install”

此处设置字符集，SGA Target等。

Qwe123456

[root@DB-Server Server]# /u01/oraInventory/orainstRoot.sh

Changing permissions of /u01/oraInventory.

Adding read,write permissions for group.
