创建用户和组（用root用户创建）
/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/useradd -g oinstall -G dba oracle
（给oracle用户添加密码)
#passwd oracle
创建安装oracle客户端软件时所需要的目录
# mkdir -p /u01/app/
# chown -R oracle:oinstall /u01/app/
# chmod -R 775 /u01/app/
编辑/etc/hosts文件
#自己的IP和主机名
192.168.3.62 oraclient
#数据库的IP和实例名
192.168.3.61 orcl
以下环境都在oracle用户下执行
用户环境变量
ORACLE_BASE=/u01/app/oracle
ORACLE_SID=orcl
export ORACLE_BASE $ORACLE_SID
export ORACLE_OWNER=oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/client_1
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:usr/lib
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export LANG=en_US
安装软件
1、将oracle 11.2.0.3客户端的包上传到oracle安目录下并解压
（查看软件包）
[oracle@oraclient ~]$ ls
p10404530_112030_Linux-x86-64_4of7.zip
（解压软件包）
[oracle@oraclient ~]$ unzip p10404530_112030_Linux-x86-64_4of7.zip
（查看解压的包）
[oracle@oraclient ~]$ ll
total 643788
drwxr-xr-x 6 oracle oinstall 4096 Sep 22 2011 client
-rw-r--r-- 1 oracle oinstall 659229728 Feb 5 11:30 p10404530_112030_Linux-x86-64_4of7.zip
2、开始安装软件，进入到"client"目录并执行安装命令
[oracle@oraclient ~]$ chown oracle:oinstall -R client
[oracle@oraclient ~]$ chmod 775 -R client
[oracle@oraclient ~]$ cd client/
[oracle@oraclient client]$ ./runInstaller
（在弹出的界面中选择 “Administrator(1.38GB)”-->"Next")
(在随后弹出界面中选择自己想要的语言，然后"Next")
(接下来一直选择默认就好，直到最后弹出一个界面，让执行一个脚本，到此安装完成）
3、配置Tnsname.ora
切换到oracle启用并执行netca命令
[oracle@oraclient ~]$ netca
（在弹出的界面中选择“Local Net Service Name configuration”进行配置）
（选择“Add”然后选择"Next")
（输入 orcl数据库的实例名后再选择“next”)
（这里默认TCP通信协议，点“Next”)
（输入数据库服务器的IP地址，然后一直点击 “Next”直到配置完成）
4、连接测试
[oracle@oraclient ~]$ sqlplus system/redhat@orcl
#账号 #密码 #数据库实例名
