只安装需要远程连接的oracle客户端

需求：
服务端在172.16.100.102，现在需要在Linux上安装连接服务端的oracle客户端。

一、下载

oracle官网地址
或复制：
http://www.oracle.com/technetwork/database/database-technologies/instant-client/overview/index.html

• 1、点击downloads

  

• 2、选择系统版本
  
• 3、选择客户端需要的3个文件，basic，sqlplus，sd****k
  

下载完之后，上传到Linux服务器。

二、解压

mkdir -p /opt/oracle/lib 
mkdir -p /opt/oracle/network/admin

unzip instantclient-basic-linux.x64-11.2.0.4.0.zip
unzip instantclient-sqlplus-linux.x64-11.2.0.4.0.zip
unzip instantclient-sdk-linux.x64-11.2.0.4.0.zip

自动会解压到:

/root/instantclient_11_2

[root@worker-136 ~]# cd instantclient_11_2/
mv sdk  /opt/oracle/sdk
mv *  /opt/oracle/lib

三、配置环境变量

vim /etc/profile

export JAVA_HOME=/usr/local/jdk1.8.0_171
export JAVA_BIN=/usr/local/jdk1.8.0_171/bin
export PATH=${JAVA_HOME}/bin:$PATH
export CLASSPATH=.:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tools.jar

ORACLE_HOME=/opt/oracle
DYLD_LIBRARY_PATH=$ORACLE_HOME/lib
PATH=$JAVA_HOME/bin:$ANT_HOME/bin:$ORACLE_HOME/lib:$PATH
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME ANT_HOME PATH CLASSPATH DYLD_LIBRARY_PATH ORACLE_HOME LD_LIBRARY_PATH
export TNS_ADMIN=$ORACLE_HOME/network/admin

:wq

source /etc/profile    //立即生效

vim /root/.bash_profile

export ORACLE_HOME=/opt/oracle
export PATH=$ORACLE_HOME:$PATH
export TNS_ADMIN=$ORACLE_HOME/network/admin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:$ORACLE_HOME

:wq

source /root/.bash_profile        //立即生效

四、配置oracle参数(也可以省略)

此步骤是为了客户端直接使用监听名字方便，
比如服务端的监听名字是：orcl

修改三个配置：

[root@worker-136 admin]# cd  /opt/oracle/network/admin
[root@worker-136 admin]# ll
总用量 12
-rw-r--r-- 1 root root 280 7月   3 14:22 listener.ora
-rw-r--r-- 1 root root  87 7月   3 14:24 sqlnet.ora
-rw-r--r-- 1 root root 312 7月   3 14:19 tnsnames.ora

这三个文件配置如下：
listener.ora

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = orcl)
      (ORACLE_HOME = /opt/oracle)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.100.102)(PORT = 1521))
    )
  )

sqlnet.ora

SQLNET.AUTHENTICATION_SERVICES= (NTS)

NAMES.DIRECTORY_PATH= (TNSNAMES,EZCONNECT)

tnsnames.ora

LISTENER_ORCL =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.100.102)(PORT = 1521))



ORCL =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.100.102)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

五、测试连接

连接成功！

[root@worker-136 admin]# sqlplus census/oracle@172.16.100.102:1521/orcl
