一、修改主机名和IP地址：
[root@localhost Desktop]# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
192.168.1.203 rusky-oel.com rusky-oel
[root@localhost Desktop]# cat /etc/hostname
rusky-oel.com
[root@localhost VH-share]# vi /etc/sysconfig/network-scripts/ifcfg-eno16777736
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
NAME=eth0
UUID=7ca2767c-872e-4e2b-aac4-40e075b64f31
ONBOOT=yes
HWADDR=00:0C:29:AE:DB:8A
IPADDR0=192.168.1.205
PREFIX0=24
GATEWAY0=192.168.1.1
DNS1=222.172.200.68
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
二、修改SElinux，Firewall,SSH
•If the OS is to be used for an Oracle installation, it is easier if Secure Linux (SELinux) is disabled or switched to
permissive. To do this edit the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.
SELINUX=permissive 或者:SELINUX=disabled
If SELinux is configured after installation, the server will need a reboot for the change to take effect.
Firewall
•If the OS is to be used for an Oracle installation, it is easier if the firewall is disabled. This can be done by issuing
the following commands from a terminal window as the "root" user.
# systemctl stop firewalld
# systemctl disable firewalld
SSH
•Make sure the SSH daemon is started using the following commands.
# systemctl start sshd.service
# systemctl enable sshd.service
三、修改内核参数
Set Kernel Parameters
Add or amend the following lines in the "/etc/sysctl.conf" file.
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
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
Run the following command to change the current kernel parameters.
/sbin/sysctl -p
Add the following lines to the "/etc/security/limits.conf" file.
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 4096
oracle hard nofile 65536
oracle soft stack 10240
Add the following line to the "/etc/pam.d/login" file, if it does not already exist.
session required pam_limits.so
四、安装环境检查及设置
Setup
1、检查所需包是否安装
The following packages are listed as required, including the 32-bit version of some of the packages. Many of the packages
should be installed already.
yum install binutils -y
yum install compat-libstdc++-33 -y
yum install compat-libstdc++-33.i686 -y
yum install gcc -y
yum install gcc-c++ -y
yum install glibc -y
yum install glibc.i686 -y
yum install glibc-devel -y
yum install glibc-devel.i686 -y
yum install ksh -y
yum install libgcc -y
yum install libgcc.i686 -y
yum install libstdc++ -y
yum install libstdc++.i686 -y
yum install libstdc++-devel -y
yum install libstdc++-devel.i686 -y
yum install libaio -y
yum install libaio.i686 -y
yum install libaio-devel -y
yum install libaio-devel.i686 -y
yum install libXext -y
yum install libXext.i686 -y
yum install libXtst -y
yum install libXtst.i686 -y
yum install libX11 -y
yum install libX11.i686 -y
yum install libXau -y
yum install libXau.i686 -y
yum install libxcb -y
yum install libxcb.i686 -y
yum install libXi -y
yum install libXi.i686 -y
yum install make -y
yum install sysstat -y
yum install unixODBC -y
yum install unixODBC-devel -y
yum install zlib-devel -y
yum install elfutils-libelf-devel -y
Create the new groups and users.
2、创建用户及组
groupadd -g 54321 oinstall
groupadd -g 54322 dba
groupadd -g 54323 oper
#groupadd -g 54324 backupdba
#groupadd -g 54325 dgdba
#groupadd -g 54326 kmdba
#groupadd -g 54327 asmdba
#groupadd -g 54328 asmoper
#groupadd -g 54329 asmadmin
useradd -g oinstall -G dba,oper oracle
passwd oracle
Note. We are not going to use the extra groups, but include them if you do plan on using them.
3、创建安装目录
Create the directories in which the Oracle software will be installed.
mkdir -p /u01/app/oracle/product/11.2.0.4/db_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01
If you are using X Emulation, login as root and issue the following command.
xhost +<machine-name>
4、oracle用户环境变量修改
Login as the oracle user and add the following lines at the end of the "/home/oracle/.bash_profile" file.
以oracle用户登录添加如下内容到这个文件：/home/oracle/.bash_profile
# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_HOSTNAME=rusky-oel.com; export ORACLE_HOSTNAME
ORACLE_UNQNAME=DB11G; export ORACLE_UNQNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0.4/db_1; export ORACLE_HOME
ORACLE_SID=orcl; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
五、执行安装
installation
Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.
DISPLAY=192.168.1.203:0.0; export DISPLAY
Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory.
./runInstaller DISPLAY报错处理：http://www.cnblogs.com/rusking/p/4232835.html
《参数文档： http://oracle-base.com/articles/11g/oracle-db-11gr2-installation-on-oracle-linux-7.php》
=========
安装过程中报错，处理方法：
1、检查安装环境时，缺少pdksh包，忽略即可。
Proceed with the installation of your choice. You can see type of installation I performed by clicking on the links below to see screen shots of each stage. The "pdksh" package will be listed as missing, which can be ignored because we installed the "ksh" package instead.
2、ins_emagent.mk报错
During the link phase you will encounter an error invoking the "ins_emagent.mk" file. To fix this, edit the "$ORACLE_HOME/sysman/lib/ins_emagent.mk", doing a search and replace for the line shown below.
FROM: $(MK_EMAGENT_NMECTL) TO : $(MK_EMAGENT_NMECTL) -lnnz11
Click the "Retry" button.
