Autoconf installation

root@linux:~# wget http://ftp.gnu.org/gnu/m4/m4-1.4.9.tar.gz
root@linux:~# tar -zvxf m4-1.4.9.tar.gz
root@linux:~# cd m4-1.4.9/
root@linux:~# ./configure && make && make install
root@linux:~# cd ..
root@linux:~# wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.62.tar.gz
root@linux:~# tar -zvxf autoconf-2.62.tar.gz
root@linux:~# cd autoconf-2.62/
root@linux:~# ./configure && make && make install

Register and Download Oracle Instant Client. Choose your platform compatibility, if the package not compatible with your platform then installation process will failed. At least, we just need Basic and SDK. Then put on /opt/oracle or whatever directory did you liked.

root@linux:~# mkdir -p /opt/oracle
root@linux:~# cd /opt/oracle
root@linux:~# unzip instantclient-basic-linux32-11.2.0.1.zip
root@linux:~# unzip instantclient-sdk-linux32-11.2.0.1.zip
root@linux:~# mv /opt/oracle/instantclient_11_2 /opt/oracle/instantclient

Create symbolic links for dinamic library and Add instant client to system ld.

root@linux:~# cd /opt/oracle/instantclient
root@linux:~# ln -s libclntsh.so.11.1 libclntsh.so
root@linux:~# ln -s libocci.so.11.1 libocci.so
root@linux:~# echo /opt/oracle/instantclient > /etc/ld.so.conf

Compiling OCI8 and enter instantclient,/opt/oracle/instantclient when you are prompted.

root@linux:~# pecl install oci8

Enable oci8 extension on php.ini then restart apache2 web server

root@linux:~# echo extension=oci8.so > /usr/local/lib/php.ini
root@linux:~# echo extension=oci8.so > /etc/php5/cli/php.ini
root@linux:~# sudo /etc/init.d/apache2 restart

Then check phpinfo() and the successfull installation should be :

I’ve got an error before, the error are no oci8 extensions on phpinfo() after installation finished and oci8.so added to php.ini. We can manually check with php command on console. And just install libaio with apt.

root@linux:~# php
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20090626/oci8.so' - libaio.so.1: cannot open shared object file: No such file or directory in Unknown on line 0
