Linux下Oracle client客户端安装

0、zip格式 

(0)下载地址:

a、Oracle官网

(1)安装过程:

a、将zip文件分别解压到/software/下,放在同一个目录instandclient_11_2/下

b、在/software/instandclient_11_2/文件夹下,创建network/admin/文件夹;
并在/software/instandclient_11_2/network/admin/目录下创建文件tnsnames.ora

[root@localhost admin]# cat tnsnames.ora 
zkl =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.125)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SID = orcl )
      (SERVER=DEDICATED )
    (INSTANCE_NAME = testdb1) )

c、在版本18.3之前,为Instant Client版本创建适当的链接。例如:

[root@localhost software]# cd /software/instantclient_11_2/
[root@localhost instantclient_11_2]# ln -s libclntsh.so.12.1 libclntsh.so
[root@localhost instantclient_11_2]# ln -s libocci.so.12.1 libocci.so

d、向.bash_profile文件中添加如下代码:

//修改配置文件,直接在末未添加如下内容
[root@localhost software]# vi ~/.bash_profile 
export ORACLE_HOME=/software/instandclient_11_2
export PATH=$ORACLE_HOME:$PATH
export ORACLE_SID=orcl
export TNS_ADMIN=$ORACLE_HOME/network/admin
export LD_LIBRARY_PATH=$ORACLE_HOME:$LD_LIBRARY_PATH
#export NLS_LANG='simplified chinese_china'.ZHS16GBK
export NLS_LANG='simplified chinese_china'.AL32UTF8
//重新加载配置文件生效
[root@localhost software]# source ~/.bash_profile

注:ORACLE_HOME是你自己的安装地址,NLS_LANG是显示的字符编码集格式。

e、如果不想将环境配置写在.bash_profile中,也可以直接在/etc/profile中配置

ORACLE_HOME=/software/instantclient_11_2
ORACLE_SID=orcl
TNS_ADMIN=$ORACLE_HOME/network/admin
LD_LIBRARY_PATH=$ORACLE_HOME:$LD_LIBRARY_PATH
#export NLS_LANG='simplified chinese_china.ZHS16GBK'
NLS_LANG='simplified chinese_china.AL32UTF8'
export PATH=$ORACLE_HOME:$ORACLE_SID:$TNS_ADMIN:$LD_LIBRARY_PATH:$NLS_LANG:$PATH

致此,你就可以放心的连接数据库了。

f、连接诶测试

[root@localhost instantclient_11_2]# sqlplus scott/tiger@//192.168.1.125:1521/testdb1
[root@localhost instantclient_11_2]# sqlplus scott/tiger@zkl
