概述
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
# 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
# yum install libaio
# cd ~
# wget http://pecl.php.net/get/oci8-1.3.5.tgz
3.然后执行命令
# 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
# mkdir ext/
把oci8.so文件拷贝到php.ini 的ext目录里面
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.
