最近的項目需要用php訪問oracle數據庫，不得不在linux下給php安裝oci8擴展。php也可以使用pdo訪問oracle數據庫，但還是需要安裝客戶端。
首先到oracle官網的這個頁面下載相關的文件，注意要連數據庫服務器的版本，一定要對應，否則安裝成功也會連不上，同時也要區分32位、64位服務器，比如我要連的數據庫服務器是oracle10.2.0.4，64位主機，那么我要下載下面三個文件：
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.用以下命令安裝
# 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.安裝OCI8 PHP擴展
# yum install libaio
# cd ~
# wget http://pecl.php.net/get/oci8-1.3.5.tgz
3.然后執行命令
# 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(這里多運行幾次,直到出現如下提示)
[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.創建ext目錄
# mkdir ext/
把oci8.so文件拷貝到php.ini 的ext目錄里面
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
重啟apache服務:
/usr/local/apache2/bin/apachectl stop
/usr/local/apache2/bin/apachectl start
刷新測試頁面。發現oci8出現了,則大功告成.
