一、Docker运行Oracle 12c服务

a.拉取镜像

docker pull truevoly/oracle-12c

b.运行

docker run -d -p 1521:1521 -p 2484:2484 -v /data/oracle/:/opt/oracle --name oracle_12c truevoly/oracle-12c

c.查看日志

docker logs -f oracle_12c

d.出现如下信息，则启动成功

e.客户端连接测试

连接信息如下：
hostname: localhost
port: 1521
username1: system
password1: oracle
sid: xe

二、配置SSL

a.进入docker容器

docker exec -it oracle_12c /bin/bash# 安装vim
apt-get update
apt-get install vim
# 修改目录权限
chown oracle:dba /opt/oracle/ -R
# 切换到oracle用户
su oracle

b.生成key

mkdir -p /opt/oracle/wallet
# 生成key
$ORACLE_HOME/bin/orapki wallet create -wallet /opt/oracle/wallet -pwd test@123 -auto_login
$ORACLE_HOME/bin/orapki wallet add -wallet /opt/oracle/wallet  -pwd test@123   -dn "CN=`hostname`" -keysize 1024 -self_signed -validity 365
# 查看key信息
$ORACLE_HOME/bin/orapki wallet display -wallet /opt/oracle/wallet -pwd test@123
# 生成jks文件
$ORACLE_HOME/bin/orapki wallet pkcs12_to_jksls -wallet /opt/oracle/wallet -pwd test@123 -jksKeyStoreLoc /opt/oracle/wallet/oracle12c_ks.jks -jksKeyStorepwd test@123 -jksTrustStoreLoc /opt/oracle/wallet/oracle12c_ts.jks -jksTrustStorepwd test@123# /opt/oracle/wallet目录下会生成如下6个文件
cwallet.sso
cwallet.sso.lck
ewallet.p12
ewallet.p12.lck
oracle12c_ks.jks
oracle12c_ts.jks

c.修改配置文件

cd /u01/app/oracle/product/12.1.0/xe/network/admin
# 分别添加三个配置文件
vim listener.ora
vim sqlnet.ora
vim tnsnames.ora

文件内容如下：

• listener.ora

SSL_CLIENT_AUTHENTICATION = FALSEWALLET_LOCATION =(SOURCE =(METHOD = FILE)(METHOD_DATA =(DIRECTORY = /opt/oracle/wallet)))LISTENER =
(DESCRIPTION_LIST =(DESCRIPTION =(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))(ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521)))(DESCRIPTION =(ADDRESS = (PROTOCOL = TCPS)(HOST = 0.0.0.0)(PORT = 2484)))
)DEDICATED_THROUGH_BROKER_LISTENER=ON
DIAG_ADR_ENABLED = off

• sqlnet.ora

WALLET_LOCATION =(SOURCE =(METHOD = FILE)(METHOD_DATA =(DIRECTORY = /opt/oracle/wallet)))SQLNET.AUTHENTICATION_SERVICES = (TCPS,NTS,BEQ)
SSL_CLIENT_AUTHENTICATION = FALSE
SSL_CIPHER_SUITES = (SSL_RSA_WITH_AES_256_CBC_SHA, SSL_RSA_WITH_3DES_EDE_CBC_SHA)

• tnsnames.ora

SSL=
(DESCRIPTION =(ADDRESS = (PROTOCOL = TCPS)(HOST = 0.0.0.0)(PORT = 2484))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = XE))
)XE=
(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = XE))
)

d.重启listener

$ORACLE_HOME/bin/lsnrctl stop
$ORACLE_HOME/bin/lsnrctl start
# 查看listener状态
$ORACLE_HOME/bin/lsnrctl status

e.重启oracle

$ORACLE_HOME/bin/sqlplus / as sysdba
shutdown
startup

三、验证SSL

a.sqlplus验证

$ORACLE_HOME/bin/sqlplus system/oracle@SSL# 出现如下信息则成功：
SQL*Plus: Release 12.1.0.2.0 Production on Tue Sep 19 09:34:12 2023Copyright (c) 1982, 2014, Oracle.  All rights reserved.Last Successful login time: Tue Sep 19 2023 08:56:51 +00:00Connected to:

b.java代码验证
