2. 新建 linux用户 oraclelinux
useradd oracle passwd oracle 连续两次输入密码，默认oracle的目录是/home/oracle 切换到oracle用户，目录天然在/home/oracle su - oracle
3. 上传解压 unzip解压四个会解压到一个文件夹中，例如：instantclient_12_1sql
4. 修改环境变量bash
vi ~/.bash_profile #添加如下内容 export ORACLE_HOME=/home/oracle/instantclient_12_1 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME export PATH=$PATH:$ORACLE_HOME export TNS_ADMIN=$ORACLE_HOME/network/admin export NLS_LANG=AMERICAN_AMERICA.UTF8 source ~/.bash_profile
五、新建tnsnames.rsa文件oracle
#新建文件夹 mkdir -p /home/oracle/instantclient_12_1/network/admin cd /home/oracle/instantclient_12_1/network/admin vi tnsnames.ora #添加如下内容 orcl= (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 172.17.1.18)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = orcl) ) )
6. 验证spa
sqlplus username/password@ip:port/service_name sqlplus username/password@orcl
