ORACLE 11.2.0.4 安装在 rhel6 上

1. 修改host文件，添加本机的host记录
[root@RACDG ~]# vi /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.56.16    RACDG2. 修改/etc/sysctl.conf文件，添加如下几行
[root@RACDG ~]# vi /etc/sysctl.conf 
fs.suid_dumpable = 1
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 984754176
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
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=1048586


3. 运行下面命令使其生效
[root@RACDG ~]# /sbin/sysctl -p

4. 编辑/etc/security/limit.conf,添加下面几行
[root@RACDG ~]# vi /etc/security/limits.conf 
oracle              soft    nproc   16384
oracle              hard    nproc   16384
oracle              soft    nofile  4096
oracle              hard    nofile  65536
oracle              soft    stack   10240


5. 添加用户和组，以及添加oracle用户密码：
[root@RACDG ~]# groupadd -g 501 oinstall
[root@RACDG ~]# groupadd -g 502 dba
[root@RACDG ~]# groupadd -g 503 oper
[root@RACDG ~]# groupadd -g 504 asmadmin
[root@RACDG ~]# groupadd -g 506 asmdba
[root@RACDG ~]# groupadd -g 505 asmoper
[root@RACDG ~]# useradd -u 502 -g oinstall -G dba,asmdba,oper oracle
[root@RACDG ~]# passwd oracle


6. 修改/etc/security/limits.d/90-nproc.conf,做如下修改：
[root@RACDG ~]# vi /etc/security/limits.d/90-nproc.conf 
# Change this
*          soft    nproc    1024

# To this
* - nproc 16384


7. 创建目录：
[root@RACDG ~]# mkdir -p /u01/app/oracle/product/11.2.0/db_1
[root@RACDG ~]# chown -R oracle:oinstall /u01
[root@RACDG ~]# chmod -R 775 /u01


8.修改环境变量，添加如下几行：
[root@RACDG ~]# su - oracle
[oracle@RACDG ~]$ vi .bash_profile 

ORACLE_HOSTNAME=RACDG; export ORACLE_HOSTNAME
ORACLE_UNQNAME=orcl; export ORACLE_UNQNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME
ORACLE_SID=orcl; export ORACLE_SID

PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH


9. 配置yum源：
[root@RACDG ~]# mkdir /mnt/rhel6
[root@RACDG ~]# mount /dev/cdrom /mnt/rhel6/
mount: block device /dev/sr0 is write-protected, mounting read-only
10. 修改配置文件如下：
[root@RACDG ~]# vi /etc/yum.repos.d/rhel-source.repo 
[rhel-source]
name=Rhel-Source
baseurl=file:///mnt/rhel6
enabled=1
gpgcheck=0


11. 安装依赖包：
[root@RACDG ~]# yum install -y binutils compat-libcap1 compat-libstdc++ gcc gcc-c++ glibc glibc-devel ksh libgcc libstdc++ libstdc++-devel libaio libaio-devel sysstat make elfutils-libelf-devel compat-libstdc++-33-3.2.3
Complete!

12. 创建临时路径，将安装包上传到该路径下面，并解压该安装包
[root@RACDG ~]# mkdir /tmp/orasoft
[root@RACDG ~]# cd /tmp/orasoft/
[root@RACDG orasoft]# unzip p13390677_112040_Linux-x86-64_1of7.zip 
[root@RACDG orasoft]# unzip p13390677_112040_Linux-x86-64_2of7.zip  


13. 解压完成之后，可以看到生成了database文件夹
[root@RACDG orasoft]# ls
database  pdksh-5.2.14-37.el5_8.1.i386.rpm

14. 利用Xmanager中的Xmanager-Passive进行图形化安装
[root@RACDG orasoft]# export DISPLAY=192.168.56.1:0.0
[root@RACDG orasoft]# xhost +
[root@RACDG orasoft]# su - oracle
[oracle@RACDG ~]$ cd /tmp/orasoft/database/
[oracle@RACDG database]$ ./runInstaller


15. 进行网络配置
[oracle@RACDG database]$ netca

16. 进行数据库安装
[oracle@RACDG database]$ dbca
