CentOS 6安装Oracle 11gR2数据库
1. 安装前准备
[1] 安装软件包
[root@localhost var]# yum -y install binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel
gcc gcc-c++ libaio libaio-devel libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel
安装软件包 pdksh-5.2.14-36.el5.i386.rpm （这个包yum源里没有，所以要手动安装，不装安装oracle时会有警告出现，但不影响最后的使用）
请下载这个包上传到CentOS后使用如下命令安装。（软件包见附件）
[root@localhost public_root]# rpm -ivh pdksh-5.2.14-36.el5.i386.rpm
[2] 更改kernel参数
[root@localhost var]# vi /etc/sysctl.conf# Disable netfilter on bridges.#net.bridge.bridge-nf-call-ip6tables = 0#net.bridge.bridge-nf-call-iptables = 0#net.bridge.bridge-nf-call-arptables = 0# Controls the default maxmimum size of a mesage queuekernel.msgmnb = 65536# Controls the maximum size of a message, in byteskernel.msgmax = 65536# Controls the maximum shared segment size, in byteskernel.shmmax = 4294967295# Controls the maximum number of shared memory segments, in pageskernel.shmall = 268435456# 在文件末尾添加net.ipv4.ip_local_port_range = 9000 65500fs.file-max = 6815744kernel.shmall = 10523004kernel.shmmax = 6465333657kernel.shmmni = 4096kernel.sem = 250 32000 100 128net.core.rmem_default=262144net.core.wmem_default=262144net.core.rmem_max=4194304net.core.wmem_max=1048576fs.aio-max-nr = 1048576
执行以下命令使更改生效
[root@localhost var]# sysctl -p
[3] 创建安装oracle所需用户与用户组
[root@localhost var]# groupadd -g 200 oinstall[root@localhost var]# groupadd -g 201 dba[root@localhost var]# useradd -u 440 -g oinstall -G dba -d /usr/oracle oracle[root@localhost var]# passwd oracle
[root@localhost var]# vi /etc/pam.d/login#%PAM-1.0auth [user_unknown=ignore success=ok ignore=ignore default=bad] pam_securetty.soauth include system-authaccount required pam_nologin.soaccount include system-authpassword include system-auth# pam_selinux.so close should be the first session rulesession required pam_selinux.so closesession required pam_loginuid.sosession optional pam_console.so# pam_selinux.so open should only be followed by sessions to be executed in the user contextsession required pam_selinux.so opensession required pam_namespace.sosession required pam_limits.sosession optional pam_keyinit.so force revokesession include system-auth-session optional pam_ck_connector.so
[root@localhost var]# vi /etc/security/limits.conf# 在文件末尾添加oracle soft nproc 2047oracle hard nproc 16384oracle soft nofile 1024oracle hard nofile 65536
[root@localhost var]# vi /etc/profile# 在文件末尾添加if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fifi
[4] 切换到oracle用户，并进行配置
[root@localhost ~]# su - oracle[oracle@localhost ~]$ chmod 755 /usr/oracle[oracle@localhost ~]$ mkdir /usr/oracle/app[oracle@localhost ~]$ chmod 755 /usr/oracle/app/[oracle@localhost ~]$ mkdir /usr/oracle/oradata[oracle@localhost ~]$ chmod 755 /usr/oracle/oradata/[oracle@localhost ~]$ vi ./.bash_profile# 在文件末尾添加umask 022export ORACLE_BASE=/usr/oracle/app
2. 安装oracle database
[1] 下载oracle安装文件（for linux x86）,并上传到CentOS上
http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html
[2] 解压安装文件
[root@localhost public_root]# unzip linux_11gR2_database_1of2.zip[root@localhost public_root]# unzip linux_11gR2_database_2of2.zip
[3] 以oracle用户登陆，startx命令启动图形界面，打开一个终端窗口，进行到刚刚解压database的文件夹，运行以下命令
[oracle@localhost database]$ ./runInstaller
[4] oracle安装界面启动如下图所示，输入邮件地址及密码(oracle用户），以从oralce接收安全更新等信息
[5] 仅安装数据库软体
[6] 本实例中选择安装单实例数据库
[7] 选择语言
[8] 选择要安装的版本，这里选择 “Enterprise Edition”
[9] 指定Oracle Base 与 Software Location, 我们在oracle用户的profile文件里已设置此环境变量，此处保持默认
[10] 指定Inventory Directory, 本例保持默认
[11] 指定oralce特权用户组，本例保持默认
[12] 接下来，oralce安装程序会对安装环境进行检查，本例未检查到任何问题，显示安装信息如下。直接Finish, 开始安装。
[13] 静待oracle安装
[14] 当出现以下窗口时，另开一个终端，以root用户登陆，并执行下面的命令。执行完毕后，点击OK
[root@localhost ~]# /usr/oracle/oraInventory/orainstRoot.shChanging permissions of /usr/oracle/oraInventory.Adding read,write permissions for group.Removing read,write,execute permissions for world.Changing groupname of /usr/oracle/oraInventory to oinstall.The execution of the script is complete.[root@localhost ~]# /usr/oracle/app/product/11.2.0/dbhome_1/root.shRunning Oracle 11g root.sh script...The following environment variables are set as: ORACLE_OWNER= oracle ORACLE_HOME= /usr/oracle/app/product/11.2.0/dbhome_1
[15] 至此oracle 11g R2数据库安装完毕。
[16] 其它注意事项
- 关闭SeLinux
- 配置好FTP以上传安装程序(也可以使用其它方式)
