Linux上如何安装sqlplus客户端
1.首先到Oracle的官方网站下载两个包:
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
a)RedHat/CentOS直接rpm安装。
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
b)由于是rpm包,在Debian/Ubuntu下先将其转成deb包:
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
