linux安装oracle client客户端远程连接数据库

linux安装oracle client客户端远程连接数据库。

1.到oracle官网下载basic,sqlplus,devel三个软件包

oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.tar

oracle-instantclient11.2-sqlplus-11.2.0.4.0-1.x86_64.tar

oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.tar

2.到root用户下创建一个oracle文件夹

mkdir-p /root/oracle

3.将下载的三个软件包全部解压到oracle文件夹下

tar -zxvf 软件包名(不要忘记加后缀)

4.oracle client客户端不会自动生成tnsnames.ora和listener.ora文件，所以需要从本地导入服务器oracle文件夹

5修改文件配置

vi tnsnames.ora

ORCL =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.169.1.109)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

)

)

6.配置环境变量

vi .bash_profile

export ORACLE_HOME=/usr/lib/oracle/11.2/client64

export TNS_ADMIN=$ORACLE_HOME/network/admin

export NLS_LANG='simplified chinese_china'.ZHS16GBK

export LD_LIBRARY_PATH=$ORACLE_HOME/lib

export PATH=$ORACLE_HOME/bin:$PATH

7.生效环境变量

source .bash_profile

echo $OARCLE_HOME

8.测试

/root/oracle/sqlplus username/password@orcl

9.如果出现权限不足

#chmod 777 filename
