我在RHEL6 32位上安装。使用GNOME图形界面,,安装的时候把Development Tools里的开发包都安装上,或者快速安装后搭建本地yum源再利用群组安装也可。值得注意的是swap要求至少3G,我的机器为2G物理内存。
安装过程分为两步,一是修改系统参数,二是软件及数据库安装。
修改系统参数
step1: vi /etc/sysctl.conf, 添加如下参数:
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 1073741824
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 = 1048586
保存并使之生效
/sbin/sysctl -p
如果有如下提示错误,忽略,因为即使未修改参数也提示有这个错误
error: “net.bridge.bridge-nf-call-ip6tables” is an unknown key
error: “net.bridge.bridge-nf-call-iptables” is an unknown key
error: “net.bridge.bridge-nf-call-arptables” is an unknown key
注意: kernel.shmmax’s 的值是物理内存的一半。 我的是2G内存,所以是1073741824
step2: vi /etc/security/limits.conf,添加:
Oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
step3: vi /etc/pam.d/login,添加参数:
session required pam_limits.so step4:vi /etc/profile:
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
step4: vi /etc/csh.login:
if( $USER == “oracle” ) then
limit maxproc 16384
limit descriptors 65536
umask 022
endif
step5: vi /etc/RedHat-release,修改为如下值,成功安装数据库后在修改回来:
Red Hat Enterprise Linux Server release 5.0 (Tikanga)
step6: 添加相关用户及用户组:
/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/useradd -m -g oinstall -G dba oracle
echo “oracle”|passwd –stdin oracle (我比较懒,管道命令修改oracle密码)
Step 6: 创建安装路径及修改权限:
mkdir -p /opt/11g/oracle
chown -R oracle:oinstall /opt/11g/oracle
chmod -R 775 /opt/11g/oracle
mkdir -p /opt/11g/oraInventory
chown -R oracle:oinstall /opt/11g/oraInventory
chmod -R 775 /opt/11g/oraInventory
Step 7: vi /home/oracle/.bash_profile, 其中ORACLE_SID的值可以自己定,我的设为orcl
TMP=/tmp; export TMP
ORACLE_BASE=/opt/11g/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1; export ORACLE_HOME
ORACLE_SID=orcl; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=$ORACLE_HOME/bin:/usr/sbin:$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
umask 022
使环境变量生效:
source ~/.bash_profile
