CentOS7安装Oracle 11gR2 图文详解

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）

 另外，CentOS7.0.1511 基于 RHEL7.2  参考：http://www.linuxidc.com/Linux/2015-12/126283.htm

 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 (builder@kbuilder.dev.centos.org) (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

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

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：

2.启动oralce安装，到/data/database/database/目录下，执行runInstaller

3.去掉勾，懒得填，个人使用环境不需要自动接收Oracle的安全更新。

4.下一步，只安装数据库软件，个人用不要那些玩意~~

5.选择单例安装，前面的所有配置均为单例安装。

6.添加语言

7.默认安装版本企业版-Enterprise Edition --图没了。

8.确定数据软件的安装路径，自动读取前面Oracle环境变量中配置的值。

9.理论上要创建Database Operation（OSOPER）Group:oper ,个人用，懒得建，就使用dba用户组

10.安装检查，按照提示信息一个一个解决。

swap空间不足解决 ：（要求2.67G 实际2G）

[root@localhost oracle]# free -m　　#查看当前虚拟内存
              total        used        free      shared  buff/cache   available
Mem:           1824        1369          93          10         361         250
Swap:          2048          20        2028
[root@localhost oracle]# dd if=/dev/zero of=/home/swap bs=1024 count=1024000　　#将当前swap空间由2048M 增加到 3048M 新增一个2014的swap文件
1024000+0 records in
1024000+0 records out
1048576000 bytes (1.0 GB) copied, 29.4051 s, 35.7 MB/s
[root@localhost oracle]# mkswap /home/swap
Setting up swapspace version 1, size = 1023996 KiB
no label, UUID=5e3d39d7-285e-4c74-b321-1e2b3ffabf83
[root@localhost oracle]# free -m
              total        used        free      shared  buff/cache   available
Mem:           1824        1275          95          10         454         342
Swap:          2048         141        1907
[root@localhost oracle]# swapon /home/swap　　#增加并启用虚拟内容
swapon: /home/swap: insecure permissions 0644, 0600 suggested.
[root@localhost oracle]# free -m　　#再次查看
              total        used        free      shared  buff/cache   available
Mem:           1824        1275          94          10         454         342
Swap:          3048         141        2907 

11.一个一个检查package，在准备阶段中漏掉的，此处再安装，有些系统报错是因为现有的包的版本比检测要高，最后忽略即可。（点击Check_Again 多检查几次）

12.准备完毕，fuck “Finish”开始安装。

13.安装过程是一个漫长的过程，中间有几次卡住，没有出现任何画面，屏幕中间有条小线，尝试多次，发现光标在该线上，右键点击Closed，不知道关闭了啥，又能继续安装了。先装吧，到时看安装日志再说。

 14.提示安装成功。安装日志懒得看，再说。

四、配置监听listener

1.执行netca 报错

[Oracle@localhost ~]$ netca

Oracle Net Services Configuration:
#
# An unexpected error has been detected by HotSpot Virtual Machine:
#
#  SIGSEGV (0xb) at pc=0x00007f69a69fcb9d, pid=8033, tid=140092892297024
#

[oracle@localhost ~]$  

错误原因：安装操作系统是默认主机名localhost造成错误

解决办法：

racle]# cat /etc/sysconfig/network
# Created by anaconda

[root@localhost oracle]# vi /etc/sysconfig/network　　#增加HOSTNAME
[root@localhost oracle]# cat /etc/sysconfig/network
# Created by anaconda
HOSTNAME=odb-sonny
[root@localhost oracle]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
[root@localhost oracle]# vi /etc/hosts　　#增加HOSTNAME
[root@localhost oracle]# cat /etc/hosts     
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 odb-sonny
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
[root@localhost oracle]# hostname odb-sonny　　#执行
[root@localhost oracle]#  

最后注销当前oracle用户，重新登陆即可！！这次发现打开配置界面正常，安装windows下面配置即可。

五、创建Oracle数据实例Orcl

执行dbca命令，启动oracle实例安装界面，剩下的与Windows上安装一样，不废话了：

注意：必须先创建监听，并且监听是启动中，否则报错。

六、检查安装日志检查

发现有几个错误（原因未知，后续再看）：

错误1：

INFO: /lib64/libstdc++.so.5: undefined reference to `memcpy@GLIBC_2.14'
collect2: error: ld returned 1 exit status
