CentOS7安装Oracle 11gR2 图文详解

最近要运维一个项目,准备在家办公,公司无远程作业环境,个人本本不喜欢别人碰,第一次在CentOS上安装,本案留以后使用,毕竟不是经常安装。

注:Oracle11gR2 X64安装

一、环境准备

安装包:

1.VMware-workstation-full-11.1.0-2496824.exe
2.CentOS-7-x86_64-DVD-1511.iso
3.linux.x64_11gR2_database_1of2.zip
  linux.x64_11gR2_database_2of2.zip

以上觉得不是重点,不给下载地址,不描述安装过程,安装完CentOS 7,截图如下:

第一次安装防坑,没有进行任何操作之前,先在VMware中创建该虚拟机快照,后期搞郁闷了,可以回归到该快照版本。特么还是不放心,又把该虚拟机完整克隆一份(强迫症)。

二、安装Oracle前准备

1.创建运行oracle数据库的系统用户和用户组

[sonny@localhost ~]$ su root  #切换到root
Password: 
[root@localhost sonny]# groupadd oinstall  #创建用户组oinstall
[root@localhost sonny]# groupadd dba  #创建用户组dba
[root@localhost sonny]# useradd -g oinstall -g dba -m oracle  #创建oracle用户,并加入到oinstall和dba用户组
[root@localhost sonny]# passwd oracle  #设置用户oracle的登陆密码,不设置密码,在CentOS的图形登陆界面没法登陆
Changing password for user oracle.
New password:   # 密码
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:   # 确认密码
passwd: all authentication tokens updated successfully.
[root@localhost sonny]# id oracle # 查看新建的oracle用户
uid=1001(oracle) gid=1002(dba) groups=1002(dba)
[root@localhost sonny]#

为啥要创建oinstall用户组及dba组? 参考:http://www.oracle.com/technetwork/cn/articles/hunter-rac11gr2-iscsi-2-092412-zhs.html#13

理论上单例按照需要3种用户组,实际只建两个oinstall和dba,后面再安装oracle数据库的时候把OSOPER组也设置是dba组。

a.oracle 清单组(一般为oinstall):
 OINSTALL 组的成员被视为 Oracle 软件的“所有者”,拥有对 Oracle 中央清单 (oraInventory) 的写入权限。在一个 Linux 系统上首次安装 Oracle 软件时, OUI 会创建 /etc/oraInst.loc 文件。该文件指定 Oracle 清单组的名称(默认为 oinstall)以及 Oracle 中央清单目录的路径。
b.数据库管理员(OSDBA,一般为 dba):
 OSDBA 组的成员可通过操作系统身份验证使用 SQL 以 SYSDBA 身份连接到一个 Oracle 实例。该组的成员可执行关键的数据库管理任务,如创建数据库、启动和关 闭实例。该组的默认名称为dba。SYSDBA 系统权限甚至在数据库未打开时也允许访问数据库实例。对此权限的控制完全超出了数据库本身的范围。不要混淆 SYSDBA  系统权限与数据库角色 DBA。DBA 角色不包括 SYSDBA 或 SYSOPER 系统权限。
c.数据库操作员组(OSOPER,一般为 oper):
 OSOPER 组的成员可通过操作系统身份验证使用 SQL 以 SYSOPER 身份连接到一个 Oracle 实例。这个可选组的成员拥有一组有限的数据库管理权限,如管理和运行备份。 该组的默认名称为oper。SYSOPER 系统权限甚至在数据库未打开时也允许访问数据库实例。对此权限的控制完全超出了数据库本身的范围。要使用该组,选择 Advanced 安装类型来安装 Oracle 数据库软件。 

2.创建oracle数据库安装目录

[sonny@localhost ~]$ su root
Password: 
[root@localhost sonny]# mkdir -p /data/oracle  #oracle数据库安装目录
[root@localhost sonny]# mkdir -p /data/oraInventory  #oracle数据库配置文件目录
[root@localhost sonny]# mkdir -p /data/database  #oracle数据库软件包解压目录
[root@localhost sonny]# cd /data
[root@localhost data]# ls  #创建完毕检查一下(强迫症)
database  oracle  oraInventory
[root@localhost data]# chown -R oracle:oinstall /data/oracle  #设置目录所有者为oinstall用户组的oracle用户
[root@localhost data]# chown -R oracle:oinstall /data/oraInventory
[root@localhost data]# chown -R oracle:oinstall /data/database
[root@localhost data]#  

3.修改OS系统标识

 oracle默认不支持CentOS系统安装,Oracle Database 11g Release 2 的 OS要求参考: https://docs.oracle.com/cd/E11882_01/install.112/e47689/pre_install.htm#LADBI1106

 我安装是64位数据库,On Linux x86-64:Red Hat Enterprise Linux 7  (RHEL 7)

 修改文件 /etc/RedHat-release 

[sonny@localhost data]$ su root
Password: 
[root@localhost data]# cat /proc/version 
Linux version 3.10.0-327.el7.x86_64 ([email protected]) (gcc version 4.8.3 20140911 (Red Hat 4.8.3-9) (GCC) ) #1 SMP Thu Nov 19 22:10:57 UTC 2015
[root@localhost data]# cat /etc/redhat-release  
CentOS Linux release 7.2.1511 (Core) 
[root@localhost data]# vi /etc/redhat-release
[root@localhost data]# cat /etc/redhat-release 
redhat-7 
[root@localhost data]#  

4.安装oracle数据库所需要的软件包

重复一遍,我安装时Oracle Database 11g Release 2 64位数据库。

Oracle Database Package Requirements for Linux x86-64 如下:(参考:https://docs.oracle.com/cd/E11882_01/install.112/e47689/pre_install.htm#BABCFJFG

操作系统:Oracle Linux 7 and Red Hat Enterprise Linux 7
The following packages (or later versions) must be installed:
binutils-2.23.52.0.1-12.el7.x86_64 
compat-libcap1-1.10-3.el7.x86_64 
gcc-4.8.2-3.el7.x86_64 
gcc-c++-4.8.2-3.el7.x86_64 
glibc-2.17-36.el7.i686 
glibc-2.17-36.el7.x86_64 
glibc-devel-2.17-36.el7.i686 
glibc-devel-2.17-36.el7.x86_64 
ksh

libXtst-1.2.2-1.el7.x86_64 
make-3.82-19.el7.x86_64 
sysstat-10.1.5-1.el7.x86_64 

 老实人,第一次搞,一个一个的安装,命令也很简单,反正文档要求高版本也可以:

[sonny@localhost data]$ su root
Password: 
[root@localhost data]# yum install binutils省略...

5.关闭防火墙 CentOS 7.2默认使用的是firewall作为防火墙

[sonny@localhost /]$ su root
Password: 
[root@localhost /]# systemctl status firewalld.service  #查看防火墙状态,运行中
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled)
   Active: active (running) since Thu 2016-04-07 18:54:29 PDT; 2h 20min ago
 Main PID: 802 (firewalld)
   CGroup: /system.slice/firewalld.service
           └─802 /usr/bin/Python -Es /usr/sbin/firewalld --nofork --nopid

Apr 07 18:54:25 localhost.localdomain systemd[1]: Starting firewalld - dynamic firewall daemon...
Apr 07 18:54:29 localhost.localdomain systemd[1]: Started firewalld - dynamic firewall daemon.
[root@localhost /]# systemctl stop firewalld.service  #关闭防火墙
[root@localhost /]# systemctl status firewalld.service  #再次查看防火墙状态,发现已关闭
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled)
   Active: inactive (dead) since Thu 2016-04-07 21:15:34 PDT; 9s ago
 Main PID: 802 (code=exited, status=0/SUCCESS)

Apr 07 18:54:25 localhost.localdomain systemd[1]: Starting firewalld - dynamic firewall daemon...
Apr 07 18:54:29 localhost.localdomain systemd[1]: Started firewalld - dynamic firewall daemon.
Apr 07 21:15:33 localhost systemd[1]: Stopping firewalld - dynamic firewall daemon...
Apr 07 21:15:34 localhost systemd[1]: Stopped firewalld - dynamic firewall daemon.
[root@localhost /]# systemctl disable firewalld.service  #禁止使用防火墙(重启也是禁止的)
Removed symlink /etc/systemd/system/dbus-org.Fedoraproject.FirewallD1.service.
Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.
[root@localhost /]#

 防火墙先禁用,搞好之后再配置,个人虚拟机,要毛线防火墙~~

6.关闭selinux(需重启生效)

[root@localhost /]# vi /etc/selinux/config
[root@localhost /]# cat /etc/selinux/config

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled   #此处修改为disabled
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted 


[root@localhost /]#

为啥要关闭selinux?因为selinux太高深,非专业人士搞不懂~~

7.修改内核参数

红色部分为添加代码

[sonny@localhost /]$ su root
Password: 
[root@localhost /]# vi /etc/sysctl.conf 
[root@localhost /]# cat /etc/sysct.conf
cat: /etc/sysct.conf: No such file or directory
[root@localhost /]# cat /etc/sysctl.conf 
# System default settings live in /usr/lib/sysctl.d/00-system.conf.
# To override those settings, enter new settings here, or in an /etc/sysctl.d/<name>.conf file
#
# For more information, see sysctl.conf(5) and sysctl.d(5).
net.ipv4.icmp_echo_ignore_broadcasts = 1
net.ipv4.conf.all.rp_filter = 1
fs.file-max = 6815744 #设置最大打开文件数
fs.aio-max-nr = 1048576
kernel.shmall = 2097152 #共享内存的总量,8G内存设置:2097152*4k/1024/1024
kernel.shmmax = 2147483648 #最大共享内存的段大小
kernel.shmmni = 4096 #整个系统共享内存端的最大数
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500 #可使用的IPv4端口范围
net.core.rmem_default = 262144
net.core.rmem_max= 4194304
net.core.wmem_default= 262144
net.core.wmem_max= 1048576
[root@localhost /]#

使配置参数生效

[root@localhost /]# sysctl -p
net.ipv4.icmp_echo_ignore_broadcasts = 1
net.ipv4.conf.all.rp_filter = 1
sysctl: setting key "fs.file-max": Invalid argument
fs.file-max = 6815744 #设置最大打开文件数
fs.aio-max-nr = 1048576
sysctl: setting key "kernel.shmall": Invalid argument
kernel.shmall = 2097152 #共享内存的总量,8G内存设置:2097152*4k/1024/1024
sysctl: setting key "kernel.shmmax": Invalid argument
kernel.shmmax = 2147483648 #最大共享内存的段大小
sysctl: setting key "kernel.shmmni": Invalid argument
kernel.shmmni = 4096 #整个系统共享内存端的最大数
kernel.sem = 250 32000 100 128
sysctl: setting key "net.ipv4.ip_local_port_range": Invalid argument
net.ipv4.ip_local_port_range = 9000 65500 #可使用的IPv4端口范围
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
[root@localhost /]#  

8.对oracle用户设置限制,提高软件运行性能(红色为添加部分)

[sonny@localhost /]$ su root
Password: 
[root@localhost /]# vi /etc/security/limits.conf 
[root@localhost /]# cat /etc/security/limits.conf
# /etc/security/limits.conf
#
#This file sets the resource limits for the users logged in via PAM.
#It does not affect resource limits of the system services.
#
#Also note that configuration files in /etc/security/limits.d directory,
#which are read in alphabetical order, override the settings in this
#file in case the domain is the same or more specific.
#That means for example that setting a limit for wildcard domain here
#can be overriden with a wildcard setting in a config file in the
#subdirectory, but a user specific setting here can be overriden only
#with a user specific setting in the subdirectory.
#
#Each line describes a limit for a user in the form:
#
#<domain>        <type>  <item>  <value>
#
#Where:
#<domain> can be:
#        - a user name
#        - a group name, with @group syntax
#        - the wildcard *, for default entry
#        - the wildcard %, can be also used with %group syntax,
#                 for maxlogin limit
#
#<type> can have the two values:
#        - "soft" for enforcing the soft limits
#        - "hard" for enforcing hard limits
#
#<item> can be one of the following:
#        - core - limits the core file size (KB)
#        - data - max data size (KB)
#        - fsize - maximum filesize (KB)
#        - memlock - max locked-in-memory address space (KB)
#        - nofile - max number of open file descriptors
#        - rss - max resident set size (KB)
#        - stack - max stack size (KB)
#        - cpu - max CPU time (MIN)
#        - nproc - max number of processes
#        - as - address space limit (KB)
#        - maxlogins - max number of logins for this user
#        - maxsyslogins - max number of logins on the system
#        - priority - the priority to run user process with
#        - locks - max number of file locks the user can hold
#        - sigpending - max number of pending signals
#        - msgqueue - max memory used by POSIX message queues (bytes)
#        - nice - max nice priority allowed to raise to values: [-20, 19]
#        - rtprio - max realtime priority
#
#<domain>      <type>  <item>         <value>
#

#*               soft    core            0
#*               hard    rss             10000
#@student        hard    nproc           20
#@faculty        soft    nproc           20
#@faculty        hard    nproc           50
#ftp             hard    nproc           0
#@student        -       maxlogins       4
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

# End of file
[root@localhost /]#  

9.配置用户的环境变量(红色部分为添加代码)

[root@localhost /]# vi /home/oracle/.bash_profile 
[root@localhost /]# cat /home/oracle/.bash_profile 
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH

export ORACLE_BASE=/data/oracle #oracle数据库安装目录
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1 #oracle数据库路径
export ORACLE_SID=orcl #oracle启动数据库实例名
export ORACLE_TERM=xterm #xterm窗口模式安装
export PATH=$ORACLE_HOME/bin:/usr/sbin:$PATH #添加系统环境变量
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib #添加系统环境变量
export LANG=C #防止安装过程出现乱码
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK  #设置Oracle客户端字符集,必须与Oracle安装时设置的字符集保持一致,如:ZHS16GBK,否则出现数据导入导出中文乱码问题
[root@localhost /]#  

使上述配置立即生效:

[oracle@localhost /]$ su root
Password: 
[root@localhost /]# source /home/oracle/.bash_profile 
[root@localhost /]#

10.上述都搞定了,上传安装包我喜欢xftp,将oracle安装包上传到/usr/local/src

CentOS7安装Oracle 11gR2 图文详解

11.解压安装包

[oracle@localhost /]$ cd /usr/local/src  #进入/usr/local/src目录
[oracle@localhost src]$ ls
linux.x64_11gR2_database_1of2.zip  linux.x64_11gR2_database_2of2.zip
[oracle@localhost src]$ unzip linux.x64_11gR2_database_1of2.zip -d /data/database/  #解压
(省略...)
[oracle@localhost src]$ unzip linux.x64_11gR2_database_2of2.zip -d /data/database/  #解压
(省略...)
[oracle@localhost src]$ su root
Password: 
[root@localhost src]# chown -R oracle:oinstall /data/database/database/
[root@localhost src]#  

三、oracle安装 

1.图形界面登陆oracle用户:
