oracle用户图形界面：

root用户执行：
yum install gcc libaio-devel compat-libstdc++-33 elfutils-libelf-devel glibc-devel glibc-headers gcc-c++ libstdc++-devel pdksh
wget -O /tmp/pdksh-5.2.14-37.el5_8.1.x86_64.rpm http://vault.centos.org/5.11/os/x86_64/CentOS/pdksh-5.2.14-37.el5_8.1.x86_64.rpm
rpm -ivh /tmp/pdksh-5.2.14-37.el5_8.1.x86_64.rpm
点fix and Check again：
root用户执行修复程序：
root执行完，再点ok
然后点ignore
点install
安装中碰到报错：
vi /u01/app/oracle/product/11.2.0/dbhome_1/sysman/lib/ins_emagent.mk
$(MK_EMAGENT_NMECTL) -lnnz11
然后点retry
最后用root执行两个脚本：
bash /u01/app/oraInventory/orainstRoot.sh
bash /u01/app/oracle/product/11.2.0/dbhome_1/root.sh
安装完成
oracle 用户执行：
vim ~/.bash_profile
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
export PATH=$ORACLE_HOME/bin:$PATH
source .bash_profile
图形界面oracle用户登录，使用dbca创建数据库：
sid ：suzhi
em没打勾
这里密码oracle
完成
配置网络
netca
lsnrctl start
lsnrctl stop
测试：linux用户oracle
export ORACLE_SID=suzhi
sqlplus / as sysdba
新建用户：
create user alex identified by alex;
grant dba to alex;
