本文详细介绍了如何下载、安装并配置Oracle客户端，包括下载安装包、声明环境变量、准备网络配置文件及连接数据库，解决ORA-21561错误的方法。

1. 下载并安装oracle客户端安装包

rpm -ivh oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm

rpm -ivh oracle-instantclient12.1-devel-12.1.0.2.0-1.x86_64.rpm

rpm -ivh oracle-instantclient12.1-sqlplus-12.1.0.2.0-1.x86_64.rpm

2. 声明环境变量

export LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client64/lib:$LD_LIBRARY_PATH
export PATH=/usr/lib/oracle/12.1/client64/bin:$PATH
export ORACLE_HOME=/usr/lib/oracle/12.1/client64/bin

3. /usr/lib/oracle/12.1/client64/bin/network/admin下准备一下文件

listener.ora sqlnet.ora tnsnames.ora

sqlnet.ora
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES)

listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /opt/oracle)
(PROGRAM = extproc)
)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)

tnsnames.ora
orcl_db =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.211.85)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
