1、安装解压缩到/data/oracleClient

  • mkdir /data/oracleClient 创建解压目录
  • unzip /data/oracleClient/instantclient-basic-linux.x64-11.2.0.4.0.zip
  • unzip /data/oracleClient/instantclient-sqlplus-linux.x64-11.2.0.4.0.zip

2、创建tnsnames.ora监听文件

  • mkdir -p network/admin
  • cd network/admin
  • vim tnsnames.ora 新建tnsnames.ora文件
 
A_IPS =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.12.192.78)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = A_IPS)
    )
  )

3、添加环境变量

家目录 cd ~   vi .bash_profile

export ORACLE_HOME=/software/instandclient_11_2
export ORACLE_SID=orcl
export TNS_ADMIN=$ORACLE_HOME/network/admin
export LD_LIBRARY_PATH=$ORACLE_HOME:$LD_LIBRARY_PATH
#export NLS_LANG='simplified chinese_china'.ZHS16GBK
export NLS_LANG='simplified chinese_china'.AL32UTF8
export PATH=$ORACLE_HOME:$PATH

4、使环境变量生效

source .bash_profile

5、测试连接Oracle数据库

方式一: sqlplus usernaem/password@主机字符串
example : sqlplus username/passwd@cm

 

方式二:sqlplus username/password@远端ip:端口号/服务名
Linux环境Oracle client客户端安装_环境变量
