1、进入oracle官网 https://www.oracle.com/database/technologies/instant-client/linux-x86-64-downloads.html 下载： oracle-instantclient-basic-21.3.0.0.0-1.el8.x86_64.rpm oracle-instantclient-sqlplus-21.3.0.0.0-1.el8.x86_64.rpm oracle-instantclient-devel-21.3.0.0.0-1.el8.x86_64.rpm 依次安装： rpm -ivh oracle-instantclient-basic-21.3.0.0.0-1.el8.x86_64.rpm rpm -ivh oracle-instantclient-sqlplus-21.3.0.0.0-1.el8.x86_64.rpm rpm -ivh oracle-instantclient-devel-21.3.0.0.0-1.el8.x86_64.rpm 安装的文件默认放在两个位置： 头文件：/usr/include/oracle/21/client64 下，如果在使用时报错找不到头文件，记得看路径是否是这个。 包文件：/usr/lib/oracle/21/client64下，包含{bin、lib}两个文件夹； 2、创建监听文件，并添加内容 cd /usr/lib/oracle/21/client64/lib/network/admin vi tnsnames.ora ORCL = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.169.1.109)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl) ) ) Note:host是远程数据库的ip地址，service_name为远程数据库的sid 配置环境变量 vi /etc/profile，添加 #配置ORACLE环境变量 vi /etc/profile export ORACLE_BASE=/usr/lib/oracle/21 export ORACLE_VERSION=21 export ORACLE_HOME=/usr/lib/oracle/21/client64 export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH export SQLPATH=$ORACLE_HOME/lib/network/admin export TNS_ADMIN=$ORACLE_HOME/lib/network/admin export NLS_LANG=AMERICAN_AMERICA....
