Wallet作用

从Oracle 10g R2开始, 通过使用Oracle Wallet达到任意用户不使用密码登录数据库(非操作系统认证方式), 这对在shell中要使用用户密码登录数据库进行操作的脚本来说是非常有用的, 可以不暴露用户密码. 比如在Oracle客户端通过mkstore命令设置Wallet认证信息, 然后通过"sqlplus/@connect_string"方式就可以直接连接数据库.

本例是让sysrls用户无需使用密码登录系统, mkstore用法如下:

$ $ORACLE_HOME/bin/mkstore

mkstore [-wrl wrl] [-create] [-createSSO] [-delete] [-deleteSSO] [-list] [-createEntry alias secret] [-viewEntry alias] [-modifyEntry alias secret] [-deleteEntry alias] [-help]

1)安装Oracle Client

2)创建wallet存放目录和修改.bash_profile
mkdir /home/sysrls/wallet
vi .bash_profile
ORACLE_BASE=/opt/oraapp
ORACLE_HOME=/opt/oraapp/client/12.1.0.2_x64_DBAocl030
TNS_ADMIN=$ORACLE_HOME/network/admin/
PATH=$ORACLE_HOME/bin:$PATH
LD_LIBRARY_PATH=${ORACLE_HOME}/lib:${LD_LIBRARY_PATH}
LANG="en_US.UTF-8"
NLS_LANG="AMERICAN_AMERICA.AL32UTF8"
ORA_NLS10=$ORACLE_HOME/nls/data
export ORACLE_BASE LANG ORACLE_HOME PATH LD_LIBRARY_PATH NLS_LANG ORA_NLS10 TNS_ADMIN

3)生成wallet
$ $ORACLE_HOME/bin/mkstore -wrl /home/sysrls/wallet -create

Enter password:<输入钱包密码>

Enter password again:<确认钱包密码>

[sysrls@cnl20059850 wallet]$ ll
total 8
-rw-------. 1 sysrls sysrls 581 Jul 18 11:01 cwallet.sso
-rw-rw-rw-. 1 sysrls sysrls 0 Jul 18 10:52 cwallet.sso.lck
-rw-------. 1 sysrls sysrls 536 Jul 18 11:01 ewallet.p12
-rw-rw-rw-. 1 sysrls sysrls 0 Jul 18 10:52 ewallet.p12.lck

4)修改网路配置
vi $ORACLE_HOME/network/admin/tnsnames.ora

CRCDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 133.9.207.35)(PORT = 2001))
)
(CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = CRCDB)
)
)

$ vi $ORACLE_HOME/network/admin/sqlnet.ora

WALLET_LOCATION=(SOURCE=(METHOD=FILE)(METHOD_DATA=(DIRECTORY=/home/sysrls/wallet)))

SQLNET.WALLET_OVERRIDE=TRUE

5)给特定数据库用户生成Credential
$ORACLE_HOME/bin/mkstore -wrl /home/u_test/wallet -createCredential CRCDB wallet test123

5) 确认用户认证信息已经加入到Wallet

$ $ORACLE_HOME/bin/mkstore -wrl $ORACLE_HOME/network/admin/wallet -listCredential

6)如何生成让wallet仅本机可用
Oracle Wallet is a container that stores authentication and signing credentials.

Trusted certificates are stored in the Oracle Wallet when the wallet is used for security credentials.

PeopleSoft enables you to create an Oracle Wallet in two ways:

ORAPKI command line - The ORAPKI tool is available with Oracle database, so this tool can be used only by those users have a license for Oracle database.

OpenSSL utility - Users who do not have a license for Oracle database can use this utility to create their own certificates.

After creating an Oracle Wallet, you must configure SSL for the Workstation Listener and Jolt Listener ports to ensure secure client and server communications.
