Centos7下安裝Sql*Plus並連線遠端Oralce伺服器

1.下載oracle sqlplus,選擇下載 .rpm檔案(以12.2版本為例)

https://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html

2. 下載兩個 .rpm檔案

oracle-instantclient12.2-basic-12.2.0.1.0-1.x86_64.rpm

oracle-instantclient12.2-sqlplus-12.2.0.1.0-1.x86_64.rpm

3. 安裝 rpm

rpm -ivh oracle-instantclient12.2-basic-12.2.0.1.0-1.x86_64.rpm

rpm -ivh oracle-instantclient12.2-sqlplus-12.2.0.1.0-1.x86_64.rpm

4.編輯sqlplus配置檔案

成功安裝rpm包後,oracle客戶端的預設路徑為: /usr/lib/oracle/12.2/client64

編輯配置檔案ld.so.conf

$ sudo vim /etc/ld.so.conf

#在檔案尾部新增--根據自己實際情況
/usr/lib/oracle/12.2/client64/lib

5. 配置oracle環境變數

編輯配置檔案.bashrc, .bashrc檔案在 ~ 路徑下,在檔案末尾加上:

#sqlplus remote configure


export ORACLE_HOME=/usr/lib/oracle/12.2/client64
export TNS_ADMIN=$ORACLE_HOME
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/loacl/lib:$LD_LIBRARY_PATH
#export SQLPATH=$ORACLE_HOME
#export NLS_LANG=AMERICAN_CHINA.ZHS16GBK
export PATH=$PATH:$ORACLE_HOME/bin

儲存,使生效: source .bashrc

6.配置oracle連線檔案tnsnames.ora

在/usr/lib/oracle/12.2/client64/路徑下新建資料夾 network/admin/,再新建檔案 tnsnames.ora

編輯tnsnames.ora

# tnsnames.ora Network Configuration File: /opt/oracle/12c/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

LISTENER_ORCL =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.122.133)(PORT = 1521))

轉接名 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.122.133)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = serviceName)
)
)

7. 測試

sqlplus username/userpwd@轉接名

查詢當前使用者下的表

select table_name from user_tables;
