PHP下的Oracle客户端扩展(OCI8)安装教程
这篇文章主要介绍了PHP下的Oracle客户端扩展(OCI8)安装教程,本文在Linux系统中实现,OCI8是用来连接Oracle数据库的PHP扩展模块,需要的朋友可以参考下
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：
- 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:
- extension_dir = "/usr/local/php5/lib/ext"
- extension = "oci8.so"
- session.save_path = "/tmp/php"
- oci8.privileged_connect = on
重启apache服务:
/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.
