在 Ubuntu 桌面上有很多图形化工具连接 Oracle 数据库, 比如 DBeaver 等, 但有时还是需要通过 sqlplus 连接远程数据库,这时需要安装 Oracle 客户端了。本文介绍 Ubuntu 下安装 Oracle 12.2.0.5 客户端的步骤。

备注:根据需要下载相应版本的客户端。
--下载以下 rpm 包
linuxidc@linuxidc:~/Downloads$ ll *.rpm

-rw-rw-r--1 linuxidc linuxidc 776K 8月2609:57 oracle-instantclient-sqlplus-10.2.0.5-1.x86_64.rpm
--安装: alien

备注:安装完成。
--运行 sqlplus
linuxidc@linuxidc:/usr/lib/oracle/10.2.0.5/client64/bin$ ./sqlplus
./sqlplus: error while loading shared libraries: libsqlplus.so: cannot open shared object file:No such file or directory
备注:是因为 lib 环境变量没加。
--环境变量添加以下
linuxidc@linuxidc:~$ vim ~/.bashrc
# env
export ORACLE_HOME=/usr/lib/oracle/10.2.0.5/client64
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
--再次测试
linuxidc@linuxidc:~$ source .bashrc
linuxidc@linuxidc:~$ which sqlplus
/usr/lib/oracle/10.2.0.5/client64/bin/sqlplus
sqlplus username/password@//dbhost:1521/SID
备注:这时测试 sqlplus 连接远程 oracle 数据库成功,文档中提到如果此步出现缺少 libaio.so.1 文件的错误,则需要运行 “sudo apt-get install libaio1” 命令。
