3.安装oracle客户端
我们先把下载的rpm放到服务器上，我们这里放到/root 目录
查看rpm默认安装的目录
[root@bogon ~]# rpm -qpl oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm /usr/lib/oracle/11.2/client64/bin/adrci /usr/lib/oracle/11.2/client64/bin/genezi /usr/lib/oracle/11.2/client64/lib/libclntsh.so.11.1 /usr/lib/oracle/11.2/client64/lib/libnnz11.so /usr/lib/oracle/11.2/client64/lib/libocci.so.11.1 /usr/lib/oracle/11.2/client64/lib/libociei.so /usr/lib/oracle/11.2/client64/lib/libocijdbc11.so /usr/lib/oracle/11.2/client64/lib/ojdbc5.jar /usr/lib/oracle/11.2/client64/lib/ojdbc6.jar /usr/lib/oracle/11.2/client64/lib/xstreams.jar
安装有两种方式rpm 和yum 推荐采用yum安装
yum安装
[root@bogon ~]# yum install oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm
rpm安装
[root@bogon ~]# rpm -ivh oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm
依次把所下载的rmp包安装
4.创建所需目录和对应的环境变量
#创建存放TNS文件的目录 [root@bogon ~]# mkdir -p /usr/lib/oracle/11.2/client64/network/admin #可以直接修改/etc/profile全局变量 #[root@bogon ~]# vi /etc/profile [root@bogon ~]# vi ~/.bash_profile #install oracle client by:xiaofeng.org export ORACLE_VERSION=11.2 export ORACLE_HOME=/usr/lib/oracle/$ORACLE_VERSION/client64 export LD_LIBRARY_PATH=$ORACLE_HOME/lib export TNS_ADMIN=$ORACLE_HOME/network/admin export NLS_LANG=AMERICAN_AMERICA.AL32UTF8 export PATH=$PATH:$ORACLE_HOME/bin
5.测试安装是否完成
退出root用户重新登陆系统
[root@bogon ~]# sqlplus system/passwd@10.0.0.110:1521/dbtst SQL*Plus: Release 11.2.0.4.0 Production on Wed Oct 16 17:24:19 2019 Copyright (c) 1982, 2013, Oracle. All rights reserved.
