centos7 安装oracle11g

2022-12-27 07:39:05

创建数据库的系统用户和用户组

$ su root　　#切换到root

# groupadd oinstall　　#创建用户组oinstall

# groupadd dba　　#创建用户组dba

# useradd -g oinstall -g dba -m oracle　　#创建oracle用户，并加入到oinstall和dba用户组

# 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.

# id oracle # 查看新建的oracle用户

uid=1001(oracle) gid=1002(dba) groups=1002(dba)

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 *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 *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。

创建oracle数据库安装目录

[localhost ~]$ su root

Password:

[root@localhost ~]# mkdir -p /data/oracle　　#oracle数据库安装目录

[root@localhost ~]# mkdir -p /data/oraInventory　　#oracle数据库配置文件目录

[root@localhost ~]# mkdir -p /data/database　　#oracle数据库软件包解压目录

[root@localhost ~]# 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]#

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

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。

对oracle用户设置限制，提高软件运行性能（红色为添加部分）

[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: [-, ]

#        - rtprio - max realtime priority

#

#<domain>      <type>  <item>         <value>

#

#*               soft    core

Error in invoking target 'agent nmhs' of makefile

解决方案
在makefile中添加链接libnnz11库的参数
修改$ORACLE_HOME/sysman/lib/ins_emagent.mk，将
$(MK_EMAGENT_NMECTL)修改为：$(MK_EMAGENT_NMECTL) -lnnz11
建议修改前备份原始文件

[oracle@ ~]$ cd $ORACLE_HOME/sysman/lib

[oracle@lib]$ cp ins_emagent.mk ins_emagent.mk.bak

[oracle@lib]$ vi ins_emagent.mk

进入vi编辑器后命令模式输入/NMECTL 进行查找，快速定位要修改的行
