- 下載 在oracle官網搜索Instant Client Downloads，下載包名例子
instantclient-basic-linux.x64-12.1.0.2.0.zip instantclient-jdbc-linux.x64-12.1.0.2.0.zip instantclient-sqlplus-linux.x64-12.1.0.2.0.zip instantclient-tools-linux.x64-12.1.0.2.0.zip
2. 新建 linux用戶 oraclelinux
useradd oracle passwd oracle 連續兩次輸入密碼，默認oracle的目錄是/home/oracle 切換到oracle用戶，目錄天然在/home/oracle su - oracle
3. 上傳解壓 unzip解壓四個會解壓到一個文件夾中，例如：instantclient_12_1sql
4. 修改環境變量bash
vi ~/.bash_profile #添加如下內容 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
#新建文件夾 mkdir -p /home/oracle/instantclient_12_1/network/admin cd /home/oracle/instantclient_12_1/network/admin vi tnsnames.ora #添加如下內容 orcl= (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 172.17.1.18)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = orcl) ) )
6. 驗證spa
sqlplus username/password@ip:port/service_name sqlplus username/password@orcl
