ORACLE安装教程
最近的项目需要用php访问oracle数据库,不得不在linux下给php安装oci8扩展。php也可以使用pdo访问oracle数据库,但还是需要安装客户端。
首先到oracle官网的这个页面下载相关的文件,注意要连数据库服务器的版本,一定要对应,否则安装成功也会连不上,同时也要区分32位、64位服务器,比如我要连的数据库服务器是oracle10.2.0.4,64位主机,那么我要下载下面三个文件:
代码如下:
oracle-instantclient-basic-10.2.0.4-1.x86_64.rpm
oracle-instantclient-devel-10.2.0.4-1.x86_64.rpm
oracle-instantclient-sqlplus-10.2.0.4-1.x86_64.rpm
1.用以下命令安装
代码如下:
# rpm -ivh oracle-instantclient-basic-10.2.0.4-1.x86_64.rpm oracle-instantclient-devel-10.2.0.4-1.x86_64.rpm oracle-instantclient-sqlplus-10.2.0.4-1.x86_64.rpm
2.安装OCI8 PHP扩展
代码如下:
# yum install libaio
# cd ~
# wget http://pecl.php.net/get/oci8-1.3.5.tgz
3.然后执行命令
代码如下:
# tar zxvf oci8-1.3.5.tgz
# cd oci8-1.3.5/
# /usr/local/php5/bin/phpize CFLAGS=/usr/lib/oracle/11.2/client64/ CXXFLAGS=/usr/lib/oracle/11.2/client64/
# ./configure --with-php-config=/usr/local/php5/bin/php-config --with-oci8=instantclient,/usr/lib/oracle/11.2/client64/lib/
# make
# make install(这里多运行几次,直到出现如下提示)
[root@webserver02 oci8-1.3.5]# make install
/bin/sh /root/oci8-1.3.5/libtool --mode=install cp ./oci8.la /root/oci8-1.3.5/modules
cp ./.libs/oci8.so /root/oci8-1.3.5/modules/oci8.so
cp ./.libs/oci8.lai /root/oci8-1.3.5/modules/oci8.la
PATH="$PATH:/sbin" ldconfig -n /root/oci8-1.3.5/modules
----------------------------------------------------------------------
Libraries have been installed in:
/root/oci8-1.3.5/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
Installing shared extensions: /usr/local/php5/lib/php/extensions/no-debug-zts-20090626/
# cd /usr/local/php5/lib
4.创建ext目录
代码如下:
# mkdir ext/
把oci8.so文件拷贝到php.ini 的ext目录里面
代码如下:
# cp /root/oci8-1.3.5/modules/oci8.so /usr/local/php5/lib/ext/
5.在php.ini里面加上extension=oci8.so
如下:
代码如下:
extension_dir = "/usr/local/php5/lib/ext"
extension = "oci8.so"
session.save_path = "/tmp/php"
oci8.privileged_connect = on
重启apache服务:
代码如下:
/usr/local/apache2/bin/apachectl stop
/usr/local/apache2/bin/apachectl start
刷新测试页面。发现oci8出现了,则大功告成.

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.

The article discusses PHP, detailing its full form, main uses in web development, comparison with Python and Java, and its ease of learning for beginners.

PHP handles form data using $\_POST and $\_GET superglobals, with security ensured through validation, sanitization, and secure database interactions.

The article compares PHP and ASP.NET, focusing on their suitability for large-scale web applications, performance differences, and security features. Both are viable for large projects, but PHP is open-source and platform-independent, while ASP.NET,

PHP's case sensitivity varies: functions are insensitive, while variables and classes are sensitive. Best practices include consistent naming and using case-insensitive functions for comparisons.
