1、检查内存空间大小

[root@tech_002 ~]# grep MemTotal /proc/meminfo
MemTotal: 3041772 kB


2、查看交换分区swap

[root@tech_002 home]# grep SwapTotal

/proc/meminfo SwapTotal: 2031608 kB


3、假如交换分区空间不够，可以增加

创建/home/swap这么一个分区文件。文件的大小是5120000个block，一般情况下1个block为1K，所以这里空间是5G。

dd if=/dev/zero of=/home/swap bs=1024 count=5120000
5120000+0 records in
5120000+0 records out
5242880000 bytes (5.2 GB) copied, 39.3974 seconds, 133 MB/s


接着再把这个分区变成swap分区。

[root@tech_002 home]# /sbin/mkswap /home/swap

Setting up swapspace version 1, size = 5242875 kB


然后把它加到fstab里面

[root@tech_002 home]# echo "/home/swap swap swap defaults 0 0" >> /etc/fstab ; cat /etc/fstab

/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
/dev/VolGroup00/LogVol01 swap swap defaults 0 0
/home/swap swap swap defaults 0 0


4、linux.net527.cn/fuwuqiyingyong/Oracle/index.html'>oracle 11g 所必须的安装包

[root@tech_002 ~]# rpm -q binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel gcc- gcc-c++ libaio-devel libaio libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel

5、配置内核参数


cat >> /etc/sysctl.conf <<EOF
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 4194304
net.core.rmem_max=4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144
EOF


然后执行



[root@tech_002 etc]# /sbin/sysctl -p
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 68719476736
kernel.shmall = 4294967296
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144


6、给系统添加oracle用户

groupadd oinstall
groupadd dba
useradd -g oinstall -G dba oracle
passwd oracle


7、添加参数

cat >> /etc/security/limits.conf <<EOF
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
EOF

 

cat >> /etc/pam.d/login <<EOF
session required /lib/security/pam_limits.so
session required pam_limits.so
EOF


cat >> /etc/profile <<EOF
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
EOF


8、创建目录

mkdir -p /oracle_11/app/
chown -R oracle:oinstall /oracle_11/app/
chmod -R 755 /oracle_11/app/
sudo mkdir /oracle_11/tmp
sudo chmod a+wr /oracle_11/tmp


9、修改用户的shell

more /home/oracle/.bash_profile
# .bash_profile
umask 022
TMP=/oracle_11/tmp
TMPDIR=/oracle_11/tmp
export TMP TMPDIR
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
export ORACLE_BASE=/oracle_11/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.1.0/db_1
export ORA_CRS_HOME=$ORACLE_BASE/crs
export ORACLE_PATH=$ORACLE_BASE/common/oracle/sql:.:$ORACLE_HOME/rdbms/admin
export ORACLE_SID=orcl
export PATH=$ORACLE_HOME/bin:$ORA_CRS_HOME/bin:${PATH}:$HOME/bin
export PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
export PATH=${PATH}:$ORACLE_BASE/common/oracle/bin
export ORACLE_TERM=xterm
export TNS_ADMIN=$ORACLE_HOME/network/admin
export ORA_NLS10=$ORACLE_HOME/nls/data
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib:$ORACLE_HOME/oracm/lib:$ORACLE_HOME/lib
export LIBPATH=$LIBPATH:$ORA_CRS_HOME/lib:$ORACLE_HOME/lib
export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib:$ORACLE_HOME/jlib:$ORACLE_HOME/network/jlib:$ORACLE_HOME/JRE
export NLS_LANG=AMERICAN_AMERICA.ZHS16G


10、用Xstart连接centos的图形界面


解压数据库文件，安装数据库

#unzip linux.x64_11gR1_database.zip
#su - oracle
$export DISPLAY=192.168.93.202:0.0
$./runInstaller
