首先创建组、用户、目录
#groupadd oinstall
#groupadd dba
#useradd -m -g oinstall -G dba oracle
#id oracle
#passwd oracle
#mkdir -p /u01/oracle
#chown -R oracle:oinstall /u01
#chmod -R 775 /u01
修改配置文件
(配置内核参数)
#cat >> /f <<EOF
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 6815744
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500
EOF
/
sbin/sysctl –p(执行此行以上生效)
#cat >> /etc/f <<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
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
umask 022
fi
EOF
#cat >> /etc/csh.login <<EOF
if ( \$USER == "oracle" ) then
limit maxproc 16384
limit descriptors 65536
umask 022
endif
EOF
切换为oracle用户
vi /home/oracle/.bash_profile 
环境变量的配置内容放在这行注释下# User specific environment and startup programs
ORACLE_SID=orcl
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
ORACLE_HOME_LISTNER=$ORACLE_HOME
PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin
export ORACLE_SID ORACLE_BASE ORACLE_HOME ORACLE_HOME_LISTNER PATH
环境变量设置生效命令source ~/.bash_profile
解压安装包到同一个目录database
并进行安装
安装路径设置为之前创建的u01/oracle目录下
(配置实例:dbca
配置监听:netca
启动实例:sqlplus / as sysdba
启动监听:lsnrctl start
启动停止em：emctl start/stop  dbconsole)
启动实例执行sqlplus / as sysdba过程中报错如下
SP2-0667: Message file sp1<lang>.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
则执行chcon -t texrel_shlib_t /u01/oracle/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1
配置监听 设置为 本地net… 其他的选择下一步即可 其中注意 实例名 ip的设定
若是linux系统下安装的oracle11g 需要通过本机的xp访问需要现在xp上安装oracle客户端 和 pl/sql developer工具
(注意:Sqlplus 用户名/密码 as sysdba)
