Linux基础
1 前言
笔者需要一个Oracle客户端用于测试与服务器之间的连通性，于是此文产生。
2 最佳实践
2.1 系统环境
OS = CentOS 6.8 x86_64
IP Address = any
Host Name = any.cmdschool.org
2.2 基础配置
2.2.1 安装所需的工具包
yum install -y unzip
2.2.2 下载软件包
cd ~ wget https://download.oracle.com/otn/linux/instantclient/185000/instantclient-basic-linux.x64-18.5.0.0.0dbru.zip wget https://download.oracle.com/otn/linux/instantclient/185000/instantclient-sqlplus-linux.x64-18.5.0.0.0dbru.zip
如果下载异常或需要其他版本，请参阅如下链接，
https://www.oracle.com/database/technologies/instant-client/linux-x86-64-downloads.html
2.2.3 解压软件包
cd ~ unzip instantclient-basic-linux.x64-18.5.0.0.0dbru.zip unzip instantclient-sqlplus-linux.x64-18.5.0.0.0dbru.zip
2.3 部署SQLPlus
2.3.1 创建目录结构
mkdir -p /usr/lib/oracle/18.5/client64/bin mkdir -p /usr/lib/oracle/18.5/client64/lib mkdir -p /usr/share/oracle/18.5/client64/doc/
2.3.2 部署软件包
cd ~/instantclient_18_5 mv adrci /usr/lib/oracle/18.5/client64/bin/ mv genezi /usr/lib/oracle/18.5/client64/bin/ mv uidrvci /usr/lib/oracle/18.5/client64/bin/mv mv libclntsh.so.18.1 /usr/lib/oracle/18.5/client64/lib/ mv libclntsh.so /usr/lib/oracle/18.5/client64/lib/ mv libclntshcore.so.18.1 /usr/lib/oracle/18.5/client64/lib/ mv libipc1.so /usr/lib/oracle/18.5/client64/lib/ mv libmql1.so /usr/lib/oracle/18.5/client64/lib/ mv libnnz18.so /usr/lib/oracle/18.5/client64/lib/ mv libocci.so.18.1 /usr/lib/oracle/18.5/client64/lib/ mv libocci.so /usr/lib/oracle/18.5/client64/lib/ mv libociei.so /usr/lib/oracle/18.5/client64/lib/ mv libocijdbc18.so /usr/lib/oracle/18.5/client64/lib/ mv libons.so /usr/lib/oracle/18.5/client64/lib/ mv liboramysql18.so /usr/lib/oracle/18.5/client64/lib/ mv network /usr/lib/oracle/18.5/client64/lib/ mv ojdbc8.jar /usr/lib/oracle/18.5/client64/lib/ mv xstreams.jar /usr/lib/oracle/18.5/client64/lib/ mv ucp.jar /usr/lib/oracle/18.5/client64/lib/ mv BASIC_LICENSE /usr/share/oracle/18.5/client64/doc/ mv BASIC_README /usr/share/oracle/18.5/client64/doc/ mv sqlplus /usr/lib/oracle/18.5/client64/bin/ mv glogin.sql /usr/lib/oracle/18.5/client64/lib/ mv libsqlplus.so /usr/lib/oracle/18.5/client64/lib/ mv libsqlplusic.so /usr/lib/oracle/18.5/client64/lib/ mv SQLPLUS_LICENSE /usr/share/oracle/18.5/client64/doc/ mv SQLPLUS_README /usr/share/oracle/18.5/client64/doc/
2.3.3 配置环境变量
vim /etc/profile.d/oracle-lient.sh
加入如下定义，
export ORACLE_CLIENT_HOME=/usr/lib/oracle/18.5/client64
export LD_LIBRARY_PATH=${ORACLE_CLIENT_HOME}/lib:$LD_LIBRARY_PATH
export PATH=${ORACLE_CLIENT_HOME}/bin:$PATH
使用如下命令加载环境变量，
source /etc/profile
另外，亦可使用如下快速命令实现，
echo 'export ORACLE_CLIENT_HOME=/usr/lib/oracle/18.5/client64' > /etc/profile.d/oracle-lient.sh
echo 'export LD_LIBRARY_PATH=${ORACLE_CLIENT_HOME}/lib:$LD_LIBRARY_PATH' >> /etc/profile.d/oracle-lient.sh
echo 'export PATH=${ORACLE_CLIENT_HOME}/bin:$PATH' >> /etc/profile.d/oracle-lient.sh
source /etc/profile
环境变量“LD_LIBRARY_PATH”用于声明库文件的路径，否则运行命令行将会收到如下提示，
sqlplus: error while loading shared libraries: libsqlplus.so: cannot open shared object file: No such file or directory
2.3.4 测试命令行运行
sqlplus -V
可见如下提示，
SQL*Plus: Release 18.0.0.0.0 - Production Version 18.5.0.0.0
2.3.5 获取使用帮助
sqlplus -h
可见如下提示，
SQL*Plus: Release 18.0.0.0.0 - Production
Version 18.5.0.0.0
Copyright (c) 1982, 2018, Oracle. All rights reserved.
Use SQL*Plus to execute SQL, PL/SQL and SQL*Plus statements.
Usage 1: sqlplus -H | -V
-H Displays the SQL*Plus version and the
usage help.
-V Displays the SQL*Plus version.
Usage 2: sqlplus [ [] [{logon | /nolog}] [] ]
is: [-AC] [-C ] [-F] [-L] [-M ""] [-NOLOGINTIME]
[-R ] [-S]
-AC Enable Application Continuity.
-C Sets the compatibility of affected commands to the
version specified by . The version has
the form "x.y[.z]". For example, -C 10.2.0
-F This option improves performance in general. It changes
the default values settings.
See SQL*Plus User's Guide for the detailed settings.
-L Attempts to log on just once, instead of
reprompting on error.
-M "" Sets automatic HTML or CSV markup of output. The options
have the form:
{HTML html_options|CSV csv_options}
See SQL*Plus User's Guide for detailed HTML and CSV options.
-NOLOGINTIME Don't display Last Successful Login Time.
-R Sets restricted mode to disable SQL*Plus commands
that interact with the file system. The level can
be 1, 2 or 3. The most restrictive is -R 3 which
disables all user commands interacting with the
file system.
-S Sets silent mode which suppresses the display of
the SQL*Plus banner, prompts, and echoing of
commands.
is: {[/][@] | / }
[AS {SYSDBA | SYSOPER | SYSASM | SYSBACKUP | SYSDG
| SYSKM | SYSRAC}] [EDITION=value]
Specifies the database account username, password and connect
identifier for the database connection. Without a connect
identifier, SQL*Plus connects to the default database.
The AS SYSDBA, AS SYSOPER, AS SYSASM, AS SYSBACKUP, AS SYSDG,
AS SYSKM and AS SYSRAC options are database administration privileges.
can be in the form of Net Service Name
or Easy Connect.
@[ | [//]Host[:Port]/]
is a simple name for a service that resolves
to a connect descriptor.
Example: Connect to database using Net Service Name and the
database net service name is ORCL.
sqlplus myusername/mypassword@ORCL
Host specifies the host name or IP address of the database
server computer.
Port specifies the listening port on the database server.
specifies the service name of the database you
want to access.
Example: Connect to database using Easy Connect and the
Service name is ORCL.
sqlplus myusername/mypassword@Host/ORCL
The /NOLOG option starts SQL*Plus without connecting to a
database.
The EDITION specifies the value for Session Edition.
is: @|[.] [ ...]
Runs the specified SQL*Plus script from a web server (URL) or the
local file system (filename.ext) with specified parameters that
will be assigned to substitution variables in the script.
When SQL*Plus starts, and after CONNECT commands, the site profile
(e.g. $ORACLE_HOME/sqlplus/admin/glogin.sql) and the user profile
(e.g. login.sql in the working directory) are run. The files may
contain SQL*Plus commands.
Refer to the SQL*Plus User's Guide and Reference for more information.
