一、下载oracle 10g sqlplus软件

http://www.oracle.com/technology/software/tech/oci/instantclient/index.html

oracle-instantclient-basic-10.2.0.4-1.i386.rpm

oracle-instantclient-sqlplus-10.2.0.4-1.i386.rpm

oracle-instantclient-devel-10.2.0.4-1.i386.rpm

二、安装rpm包

rpm -ivh oracle-instantclient-basic-10.2.0.4-1.i386.rpm

rpm -ivh oracle-instantclient-sqlplus-10.2.0.4-1.i386.rpm

rpm -ivh oracle-instantclient-devel-10.2.0.4-1.i386.rpm

三、指定sqlplus运行所需要的库

由于是RPM包安装的，因此，oracle客户端默认所在的路径为/usr/lib/oracle/10.2.0.4/client/lib/

#vi /etc/ld.so.conf

在最后加入：/usr/lib/oracle/10.2.0.4/client/lib

四、重启ldconfig

ldconfig

五、启动sqlplus

sqlplus /nolog

一、配置oracle环境变量

#vi /etc/profile最后加入

export ORACLE_HOME=/usr/lib/oracle/10.2.0.4/client

export LD_LIBRARY_PATH=:$ORACLE_HOME/lib:/usr/local/lib:$LD_LIBRARY_PATH:.

export TNS_ADMIN=$ORACLE_HOME

export PATH=$PATH:$ORACLE_HOME/bin:.

六、配置连接tnsnames.ora

test =
　　(DESCRIPTION =
　　　　(ADDRESS_LIST =
　　　　(ADDRESS = (PROTOCOL = TCP)(HOST = ip)(PORT = 1521))
　　)
　　(CONNECT_DATA =
　　　　(SID = test )
　　　　(SERVER=DEDICATED )
　　)
)

七、启动

# sqlplus 用户名/密码@test
