liunx安裝oracle client客戶端遠程連接數據庫

1.到oracle官網下載basic,sqlplus,devel三個軟件包

    oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.tar

    oracle-instantclient11.2-sqlplus-11.2.0.4.0-1.x86_64.tar

    oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.tar

2.到root用戶下創建一個oracle文件夾

    mkdir -p /root/oracle

3.將下載的三個軟件包全部解壓到oracle文件夾下

    tar -zxvf 軟件包名(不要忘記加後綴)

4.oracle client客戶端不會自動生成tnsnames.ora和listener.ora文件，所以需要從本地導入服務器oracle文件夾

5修改文件配置

    vi tnsnames.ora

    ORCL =
      (DESCRIPTION =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.169.1.109)(PORT = 1521))
        (CONNECT_DATA =
          (SERVER = DEDICATED)
          (SERVICE_NAME = orcl)
        )

      )

6.配置環境變量

    vi .bash_profile
        export  ORACLE_HOME=/usr/lib/oracle/11.2/client64
        export  TNS_ADMIN=$ORACLE_HOME/network/admin
        export  NLS_LANG='simplified chinese_china'.ZHS16GBK
        export  LD_LIBRARY_PATH=$ORACLE_HOME/lib 

        export  PATH=$ORACLE_HOME/bin:$PATH

7.生效環境變量
        source .bash_profile

        echo $OARCLE_HOME

8.測試

    /root/oracle/sqlplus username/password@orcl

9.如果出現權限不足

    #chmod 777 filename

10.哦了。繼續測試
