今天我们将为大家提供Linux安装Oracle的详细步骤。 希望能对大家有所帮助。
1、环境准备
注意:目前的Linux是CentOS-6.10-x86_64-彩色蜜粉-DVD1.iso
界面:使用图形界面
内存: 4GB
硬盘: 20GB
连接: SecureCRT,需要安装文件上传(rz命令):yum -y install lrzsz
2、程序下载
32位需要下载(需要登录帐户) :
3358 download.Oracle.com/OTN/Linux/Oracle 11g/R2/Linux _ 11gr2_ database _ 1of2. zip
3358 download.Oracle.com/OTN/Linux/Oracle 11g/R2/Linux _ 11gr2_ database _ 2of2. zip
需要下载64位(需要登录帐户) :
3358 download.Oracle.com/OTN/Linux/Oracle 11g/R2/Linux.x64 _ 11gr2_ database _ 1of2. zip
3358 download.Oracle.com/OTN/Linux/Oracle 11g/R2/Linux.x64 _ 11gr2_ database _ 2of2. zip
3、解冻程序
上传
解冻
unzip Linux.x64 _ 11gr2_ database _ 1of2. zip
unzip Linux.x64 _ 11gr2_ database _ 2of2. zip
注意: unzip可能会提示没有此命令,但这需要我们安装
yum -y install zip
yum-y安装unzip
4、移动软件
[ root @ Cao chenlei~] # mkdir-p/usr/local/Oracle
[ root @ Cao chenlei~] # mv数据库//usr/local/Oracle
5、域名映射
显示当前系统主机名:
[root@caochenlei ~]# hostname
曹成沥
显示当前系统的IP地址:
[root@caochenlei ~]# ifconfig
在末尾添加以下内容:
127.0.0.1 localhost localhost.local domain localhost4localhost4. local domain 4
:1 localhost localhost.local domain localhost6localhost6. local domain 6
192.168.112.129 caochenlei
6、关闭selinux
[根@ Cao chenlei~] # VI/etc/selinux/config
设置SELINUX=disabled
暂时关闭selinux :
[root@caochenlei ~]# setenforce 0
7、关闭防火墙
[ root @ Cao chenlei~] # serviceiptablesstop
[ root @ Cao chenlei~] # chkconfigiptablesoff
8、安装依赖软件包
[ root @ Cao chenlei~] # yum install-y彩色蜜粉utils compat-libcap1compat-libstdc-33 gcc gcc-cglibc-develkshlibgclibstddd
9、添加新用户
[ root @ Cao chenlei~] # groupadd oinstall
[根@ Cao chenlei~] # groupadd DBA
[ root @ Cao chenlei~] # useradd-go install-gdbaoracle
[ root @ Cao chenlei~] # passwd Oracle
10、修改内核文件
[ root @ Cao chenlei~] # VI/etc/sysctl.conf
在末尾添加以下内容:
fs.aio-max-nr=1048576
fs.file-max=6815744
p>kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
更新一下文件以生效:
[root@caochenlei ~]# sysctl -p
11、修改用户限制
[root@caochenlei ~]# vi /etc/security/limits.conf
在末尾添加以下内容:
oracle soft nproc 4096
oracle hard nproc 65536
oracle soft nofile 4096
oracle hard nofile 65536
修改完成后重启服务器:
[root@caochenlei ~]# reboot
12、创建安装目录
[root@caochenlei ~]# mkdir -p /data/oracle/product/11.2.0
[root@caochenlei ~]# mkdir -p /data/oracle/oradata
[root@caochenlei ~]# mkdir -p /data/oracle/inventory
[root@caochenlei ~]# chown -R oracle:oinstall /data/oracle
[root@caochenlei ~]# chmod -R 775 /data/oracle
13、设置环境变量
切换到oracle用户下:
[root@caochenlei ~]# su - oracle
[oracle@caochenlei ~]$ vi .bash_profile
在末尾添加以下内容:
ORACLE_BASE=/data/oracle
ORACLE_HOME=$ORACLE_BASE/product/11.2.0
ORACLE_SID=orcl
PATH=$PATH:$ORACLE_HOME/彩色的蜜粉
export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH
更新一下文件以生效:
[oracle@caochenlei ~]$ source .bash_profile
14、安装应用程序
这一步需要在虚拟机里进行,因为会弹出窗体程序
[oracle@caochenlei response]$ cd /usr/local/oracle/database/
[oracle@caochenlei database]$ LANG=en_US ./runInstaller
用户安装截图:
然后提示要执行两个脚本,使用root执行,可以使用SecureCRT重新新建一个连接进行
[root@caochenlei ~]# sh /data/oracle/inventory/orainstRoot.sh
Changing permissions of /data/oracle/inventory.
Adding read,write permissions for group.
Removing read,write,execute permissions for world.
Changing groupname of /data/oracle/inventory to oinstall.
The execution of the script is complete.
[root@caochenlei ~]# sh /data/oracle/product/11.2.0/dbhome_1/root.sh

执行完成,点ok,安装成功
