前言

在学习Oracle的过程中,除了要安装Oracle数据库软件以外,我们经常要在没有Oracle数据库环境的主机上安装Oracle client,以便通过网络访问Oracle服务器。现在将在RHEL 5.5 x86 系统中安装Oracle Instant Client具体步骤演示如下:

安装环境:

在本文中,RHEL 5.5 x86是安装在虚拟机中,用secureCRT进行连接。

一 、下载安装文件

安装文件在Oracle官网有相应的下载地址,地址:

找到本文中所对应的系统,进行下载。在本文中,笔者选择下载一下三个文件:

二、将安装文件上传到要安装Oracle client的虚拟机中
      在本文中,笔者用secureCRT的SFTP向RHEL 5.5 x86传输数据:

      sftp> lcd "~/Desktop/client /"
 
      sftp> lls
 
      instantclient-basic-linux-11.2.0.3.0.zip    instantclient-sdk-linux-11.2.0.3.0.zip
 
      instantclient-sqlplus-linux-11.2.0.3.0.zip  listener.ora
 
      sqlnet.ora            tnsnames.ora
 
      sftp> cd /home/oracle/
 
      sftp> put instantclient-basic-linux-11.2.0.3.0.zip 

      sftp> put instantclient-sdk-linux-11.2.0.3.0.zip
 
      sftp> put instantclient-sqlplus-linux-11.2.0.3.0.zip
      sftp> ls                                           
      instantclient-basic-linux-11.2.0.3.0.zip    instantclient-sdk-linux-11.2.0.3.0.zip
      instantclient-sqlplus-linux-11.2.0.3.0.zip
      至此,安装文件上传完毕。
 
三、创建用户
        [root@frank ~]# groupadd dba
        [root@frank ~]# groupadd oinstall
        [root@frank ~]# useradd -g oinstall -G dba oracle
        [root@frank ~]# passwd oracle
        Changing password for user oracle.
        New UNIX password:
        BAD PASSWORD: it is based on a dictionary word
        Retype new UNIX password:
        passwd: all authentication tokens updated successfully.
 
四、配置环境变量
        [root@frank ~]# su - oracle
        [oracle@frank ~]$ vi .bash_profile
     
      # .bash_profile
        # Get the aliases and functions
        if [ -f ~/.bashrc ]; then
        . ~/.bashrc
        fi
        # User specific environment and startup programs
        PATH=$PATH:$HOME/bin
        export PATH
        export ORACLE_HOME=/home/oracle/instantclient_11_2
        export TNS_ADMIN=$ORACLE_HOME
        export LD_LIBRARY_PATH=$ORACLE_HOME:/usr/local/lib:${LD_LIBRARY_PATH}
        export SQLPATH=$ORACLE_HOME
        export PATH=$PATH:$ORACLE_HOME:/home/oracle/instantclient_11_2
        [oracle@frank ~]$ source .bash_profile
        至此,环境变量配置完毕。
 
五、解压安装文件
        [oracle@frank ~]$ unzip instantclient-basic-linux-11.2.0.3.0.zip
        [oracle@frank ~]$ unzip instantclient-sdk-linux-11.2.0.3.0.zip
        [oracle@frank ~]$ unzip instantclient-sqlplus-linux-11.2.0.3.0.zip
        [oracle@frank ~]$ ls
        instantclient_11_2                        instantclient-sdk-linux-11.2.0.3.0.zip      oradiag_oracle
        instantclient-basic-linux-11.2.0.3.0.zip  instantclient-sqlplus-linux-11.2.0.3.0.zip
 
六、配置tnsname.ora文件
      在这一步中,将要连接的数据库的相关信息配置在tnsname.ora中:
        [oracle@frank ~]$ cd instantclient_11_2/
        [oracle@frank instantclient_11_2]$ vi tnsnames.ora 

        # tnsnames.ora Network Configuration File:                 
        /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
        # Generated by Oracle configuration tools.
        ENMOEDU =
        (DESCRIPTION =
        (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.80.10)(PORT = 1521))
        )
        (CONNECT_DATA =
        (SERVICE_NAME = ENMOEDU)
        )
        )
        DUPL =
        (DESCRIPTION =
        (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.80.10)(PORT = 1521))
        )
        (CONNECT_DATA =
        (SERVICE_NAME = DUPL)
        )
        )
        退出保存。至此,,tnsname.ora配置成功。
 
七、测试连接
        [oracle@frank ~]$ sqlplus sys/oracle@ENMOEDU as sysdba
        SQL*Plus: Release 11.2.0.3.0 Production on Wed Mar 5 15:44:48 2014
        Copyright (c) 1982, 2011, Oracle.  All rights reserved.
        Connected to:
        Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - Production
        With the Partitioning, OLAP, Data Mining and Real Application Testing options
 
      SQL>
     
      测试成功。
      至此 Oracle instant client 全部配置成功。
