安装Oracle数据库客户端需要root用户

1. 将oracle-instantclient-basic-10.2.0.3-1.x86_64.rpm，
   oracle-instantclient-basiclite-10.2.0.3-1.x86_64.rpm，
   oracle-instantclient-devel-10.2.0.3-1.x86_64.rpm，
   oracle-instantclient-jdbc-10.2.0.3-1.x86_64.rpm，
   oracle-instantclient-sqlplus-10.2.0.3-1.x86_64.rpm这5个文件
   拷贝到主机某目录，如

   /home/goldemv/oracleclientsetup,
   

   并cd 到该目录

2. 执行rpm安装命令：

   rpm -ivh oracle-instantclient-basic-10.2.0.3-1.x86_64.rpm
   rpm -ivh oracle-instantclient-basiclite-10.2.0.3-1.x86_64.rpm --nodeps
   rpm -ivh oracle-instantclient-devel-10.2.0.3-1.x86_64.rpm
   rpm -ivh oracle-instantclient-jdbc-10.2.0.3-1.x86_64.rpm
   rpm -ivh oracle-instantclient-sqlplus-10.2.0.3-1.x86_64.rpm
   

3. 设置环境变量
   vim /etc/profile添加如下数据

   export ORACLE_HOME=/usr/lib/oracle/10.2.0.3/client64
   export ORACLE_BASE=/usr/lib/oracle/10.2.0.3
   export LD_LIBRARY_PATH=/usr/local/SQLAPI/lib:/usr/local/mysql/lib:$ORACLE_HOME/lib:$LD_LIBRARY_PATH
   export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
   export LD_LIBRARY_PATH=$ORACLE_HOME/bin:$LD_LIBRARY_PATH
   export TNS_ADMIN=$ORACLE_HOME/network/admin
   export PATH=$ORACLE_HOME:$ORACLE_HOME/bin:$PATH
   

4. 设置生效

   source /etc/profile
   

5. 建立oracle相关目录执行以下命令：

   cd $ORACLE_HOME
   mkdir  network
   cd network
   mkdir  admin
   cd $TNS_ADMIN
