登陆WSL系统上，从Oracle下载几个压缩包

分别解压四个压缩包:

root@jinju:~# mkdir instantclient
root@jinju:~# mv instantclient-* instantclient# unzip instantclient-basic-linux.x64-21.11.0.0.0dbru.zip 
# unzip instantclient-sqlplus-linux.x64-21.11.0.0.0dbru.zip 
# unzip instantclient-sdk-linux.x64-21.11.0.0.0dbru.zip 
# unzip instantclient-jdbc-linux.x64-21.11.0.0.0dbru.zip

然后全部进入～/instantclient/instantclient_21_11里了

root@jinju:~/instantclient# cd instantclient_21_11/
root@jinju:~/instantclient/instantclient_21_11# ls

规范一下放置的路径，放到上面解压的路径也是可以的

root@jinju:~/instantclient# mkdir -p /u01/app/oracle/product/19.0.0/client_1
root@jinju:~/instantclient# cp -rf ～/instantclient/instantclient_21_11/*  /u01/app/oracle/product/19.0.0/client_1/

/etc/profile 添加路径

root@jinju:~/instantclient/instantclient_21_11# more /etc/profile
。。。
export ORACLE_HOME=/u01/app/oracle/product/19.0.0/client_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
export TNS_ADMIN=$ORACLE_HOME/network/admin
export PATH=$PATH:$ORACLE_HOME:$ORACLE_HOME/lib:$ORACLE_HOME/sdk/include

安装个JDK

root@jinju:~/instantclient/instantclient_21_11/sdk# apt install openjdk-17*

测试下SQL*Plus ，可以用连接串访问Oracle

添加tnsnames.ora 配置，简化连接串访问

root@jinju:~# cd $ORACLE_HOME/network/admin
root@jinju:/u01/app/oracle/product/19.0.0/client_1/network/admin# touch tnsnames.ora

继续测试
