How to install OCI8 on Ubuntu 17.10 and PHP 7.1

This guide refers to Instantclient Version 12.2.0.1.0

Install Oracle Instant Client and SDK

Step 1

Download the latest Oracle Instant Client and SDK from the Oracle website (Yeah, fuck you Oracle, you need to create an account to download the files).

http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html

Look for instantclient-basic-linux.x64-12.2.0.1.0.zip and instantclient-sdk-linux.x64-12.2.0.1.0.zip.

Step 2

Create a new folder to store the Oracle Instant Client files on your machine.

mkdir /opt/oracle

And move your files to /opt/oracle.

Step 3

Extract the files

cd /opt/oracle
unzip instantclient-basic-linux.x64-12.2.0.1.0.zip
unzip instantclient-sdk-linux.x64-12.2.0.1.0.zip

Step 4

Next, we need to symlink the .so files.

ln -s /opt/oracle/instantclient_12_2/libclntsh.so.12.2 /opt/oracle/instantclient_12_2/libclntsh.so
ln -s /opt/oracle/instantclient_12_2/libocci.so.12.2 /opt/oracle/instantclient_12_2/libocci.so

Step 5

Now lets add the folder to the ldconfig's config folder.

echo /opt/oracle/instantclient_12_2 > /etc/ld.so.conf.d/oracle-instantclient.conf

And update the dynamic linker runtime bindings.

ldconfig

Great! We're almost there!

Add the extension to PHP

To install the OCI8 extension, we need to get some additional packages.

Step 1

Run these commands to install the necessary packages:

apt install php-dev php-pear build-essential libaio1

Step 2

Install the oci8 extension via PECL.

echo "instantclient,/opt/oracle/instantclient_12_2" | pecl install oci8

Step 3

We now can tell PHP to load the OCI8 extension.

echo "extension=oci8.so" >> /etc/php/7.1/mods-available/oci8.ini

ln -s /etc/php/7.1/mods-available/oci8.ini /etc/php/7.1/cli/conf.d/20-oci8.ini

ln -s /etc/php/7.1/mods-available/oci8.ini /etc/php/7.1/fpm/conf.d/20-oci8.ini

Step 4

Check if the extension is enabled.

php -m | grep oci8
php-fpm7.1 -m | grep oci8

If you see oci8, you're almost done!

Step 5

Restart PHP-FPM.

service php7.1-fpm restart

Finished! Well done! Thanks for pulling through with this tedious procedure!

Take a look at /etc/php/7.1/mods-available/oci8.ini, I bet there are two lines like this:

extension=oci8.so
extension=oci8.so

Just delete one of those lines.

i've deleted one, but the problem was in the installation, because the version the i had installed was the version 19_3. So if anyone has more question about i ask that to take a look the version you're installing. Thank's

Dang I feel that I'm missing something. I followed things to a 'T'. I'm using /opt/oracle/instantclient_18_3 for my installation. I had this module working on php 7.2 since April and just yesterday upgraded to 7.3. Now things aren't coming back on line. I get down to php -m | grep oci8 and I have the following error.

$bash:/etc/php/7.3/mods-available$ php -i | grep ini
PHP Warning:  PHP Startup: Unable to load dynamic library 'oci8.so' (tried: /usr/lib/php/20180731/oci8.so (/usr/lib/php/20180731/oci8.so: cannot open shared object file: No such file or directory), /usr/lib/php/20180731/oci8.so.so (/usr/lib/php/20180731/oci8.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

I've checked my oci8.ini file for duplicated lines like @mazedlx mentioned but that didn't work cause I only have a single line for an entry.

Any thoughts on what I can do?

I think the problem is that you've upgraded PHP to 7.3, but you haven't compiled oci8 for this version yet.

@mazedlx - Thanks for the suggestion. Not sure what you mean that my OCI8 wasn't compiled for PHP 7.3. After some googling and thinking I decided to perform a

pecl uninstall oci8

I followed any prompts that came up. After the uninstall I started back over with the above tutorial at Step 2. Followed everything in the tutorial for my 18_3 install version and it worked. Thanks for your help.

Still works for 20.04, tested with PHP 7.4 and 8.0 with Oracle 21.1.0.0.0

Only URLs have slightly changed and current version of oci8 is PHP 8.0 only.
