Linux上如何安装sqlplus客户端

oracle-instantclient11.2-basic-11.2.0.2.0.x86_64.rpm

oracle-instantclient11.2-sqlplus-11.2.0.2.0.x86_64.rpm

2.安装软件包

rpm -ivh oracle-instantclient11.2-basic-11.2.0.2.0.x86_64.rpm
?
rpm -ivh oracle-instantclient11.2-sqlplus-11.2.0.2.0.x86_64.rpm

alien oracle-instantclient11.2-basic-11.2.0.2.0.x86_64.rpm

alien oracle-instantclient11.2-sqlplus-11.2.0.2.0.x86_64.rpm

得到

oracle-instantclient11.2-basic-11.2.0.2.0-2_amd64.deb

oracle-instantclient11.2-sqlplus-11.2.0.2.0-2_amd64.deb

然后dpkg安装

dpkg -i oracle-instantclient11.2-basic-11.2.0.2.0-2_amd64.deb

dpkg -i oracle-instantclient11.2-basic-11.2.0.2.0-2_amd64.deb

这样会安装在默认的目录下——/usr/lib/oracle/11.2/client64/

4.安装完成之后，还需要暴露一些环境变量

nano /etc/profile

在最后加上：

export ORACLE_HOME=/usr/lib/oracle/11.2/client64
export TNS_ADMIN=$ORACLE_HOME
export PATH=$PATH:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib

5.配置TNS连接文件。

cd /usr/lib/oracle/11.2/client64/
vi tnsnames.ora
?
TEST=
? (DESCRIPTION =
? ? (ADDRESS_LIST =
? ? ? (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.109)(PORT = 1521))
? ? )
? ? (CONNECT_DATA =
? ? ? (SERVICE_NAME=orcl )
? ? )
? )

6.执行sqlplus，如出现找不到包libaio，到这里下载并安装。

同样的道理Redhat/CentOS直接rpm安装，Debian/Ubuntu转成.deb包后安装。

wget ftp://mirror.switch.ch/pool/3/mirror/centos/4.8/os/x86_64/CentOS/RPMS/libaio-0.3.105-2.x86_64.rpm

6.再执行sqlplus，如果仍然有错，则reboot试试应该就OK了。

sqlplus system/123456@test
