ubuntu下安装 oracle客户端

1、从oracle下载Instant Client

http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html

选择适合的版本，下载rpm包

 oracle-instantclient-basic和oracle-instantclient-sqlplus

2、转换rpm为deb

sudo alien oracle-instantclient-basic.rpm

3、安装deb

sudo dkpg -i oracle-instantclient-basic.deb

4、配置环境变量

vim ~/.profile

export ORACLE_HOME=/usr/lib/oracle/10.2.0.5/client
export PATH=$PATH:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib
export TNS_ADMIN=$ORACLE_HOME/network/admin

5、立即生效变量

source ~/.profile

6、创建目录与tnsnames.ora文件

sudo mkdir -p $ORACLE_HOME/network/admin

sudo vim tnsnames.ora

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = dbserver)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

 这里需要在系统hosts文件中添加dbserver的ip对应。

7、测试连接

sqlplus 'scott/tiger@orcl'

这个单引号是必须的。
