CentOS 7 安装oracle 11G
一、安装Oracle前准备
首先要设置主机名,并在/etc/hosts下解析。
镜像没挂全,导致缺少包pdksh-5.2.14、compat-libstdc++-33-3.2.3
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]#
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
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
4.安装oracle数据库所需要的软件包
The following packages (or later versions) must be installed:
binutils-2.23.52.0.1-12.el7.x86_64

sysstat-10.1.5-1.el7.x86_64
[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

[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.
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
可以用此命令
sed -i "s/SELINUX=enforcing/SELINUX=disabled/" /etc/selinux/config // 关闭Selinux
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
二、上传软件包,解压、(调图形)安装软件、创建数据库、创建监听。至此结束。
安装软件时遇到
%86时出现报错 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@ysserver ~]$ cd $ORACLE_HOME/sysman/lib
[oracle@ysserver lib]$ cp ins_emagent.mk ins_emagent.mk.bak
[oracle@ysserver 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
在后面追加参数-lnnz11
$(SYSMANBIN)emdctl:
$(MK_EMAGENT_NMECTL) -lnnz11
保存退出后Retry
