Install Oracle Instant Client and SDK

Step 1

Download the Oracle Instant Client and SDK from Oracle website. (Need to login in Oracle page)

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

Files: instantclient-basic-linux.x64-12.1.0.2.0.zip and instantclient-sdk-linux.x64-12.1.0.2.0.zip.

Step 2

Create a new folder to store Oracle Instant Client zip files on your server.

Upload the Instant Clients files inside this folder.

mkdir /opt/oracle

Step 3

Now we need to extract the files.

cd /opt/oracle
unzip instantclient-basic-linux.x64-12.1.0.2.0.zip
unzip instantclient-sdk-linux.x64-12.1.0.2.0.zip

Step 4

Next, we need to create a symlink to Instant Client files.

ln -s /opt/oracle/instantclient_12_1/libclntsh.so.12.1 /opt/oracle/instantclient_12_1/libclntsh.so
ln -s /opt/oracle/instantclient_12_1/libocci.so.12.1 /opt/oracle/instantclient_12_1/libocci.so

Step 5

Add the folder to our ldconfig.

echo /opt/oracle/instantclient_12_1 > /etc/ld.so.conf.d/oracle-instantclient

Step 6

Update the Dynamic Linker Run-Time Bindings

ldconfig

Done. Now we can proceed to the next part.

Install Additional Packages

To install the OCI8 extension, we need to install some additional package on our server.

Step 1

Run these command:

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

Step 2

Once installed, we need to get the OCI8 file.

pecl install oci8

When you are prompted for the Instant Client location, enter the following:

instantclient,/opt/oracle/instantclient_12_1

Step 3

We need to tell PHP to load the OCI8 extension.

echo "extension = oci8.so" >> /etc/php/7.1/fpm/php.ini
echo "extension = oci8.so" >> /etc/php/7.1/cli/php.ini

Step 4

Check if the extension is enabled.

php -m | grep 'oci8'

If returns oci8, its works!

Step 5

Restart the PHP-FPM

service php7.1-fpm restart

Now you can connect to Oracle DBMS from your PHP applications.

Hello, I've done everything that you instruct here, but I couldn't connect to oracle database. I used wrong connection test example or drivers installed incorrectly. Please help me. OS: Ubuntu 16.04 LTS desktop. "php -i" results:

When calling phpinfo(); browser says:

No topic about OCI8 there, but I enabled oci8.so extension in both php fpm and cli.

php test code that I've used:

<?php

error_reporting(E_ALL);
ini_set('display_errors', 'On');

$conn = oci_connect('USERNAME', 'PASSWORD', 'DATABASE');

$stid = oci_parse($conn, 'select count(*) from SOME_TABLE');
oci_execute($stid);

echo "<table>\n";
while (($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) != false) {
    echo "<tr>\n";
    foreach ($row as $item) {
        echo "  <td>".($item !== null ? htmlspecialchars($item, ENT_QUOTES) : "&nbsp;")."</td>\n";
    }
    echo "</tr>\n";
}
echo "</table>\n";

?>

result on browser:

Fatal error: Uncaught Error: Call to undefined function oci_connect() in /var/www/html/test.php:6 Stack trace: #0 {main} thrown in /var/www/html/test.php on line 6

That code I got from here:

What I'm doing wrong?

Hello, I followed the above tutorials and I am still getting an error. :)

Steps 4 and 5 are version specific, so make sure you downloaded exactly the same version. I used tab complete on steps 4 and 5 because I had downloaded 12.2 instead of 12.1.

Hello, I followed the above tutorials and I am still getting an error. :)
for the new 12.2
Fatal error: Uncaught Error: Call to undefined function oci_connect() in /var/www/html/oracle/1.php on line 2

$conn = oci_connect("user_name_db","password", "1.0.6.10:1521/data_name");
I try many tutorials but i cant solve my problem.
Please can u help me :)

I had the same problem and did not find anything for a full day, until I found .... https://forum.remirepo.net/viewtopic.php?pid=9291#p9291
this is what worked for me:

systemctl edit apache2
inside we add these two lines

[Service]
Environment = LD_LIBRARY_PATH = / opt / oracle / instantclient

save and restart the apache service

service apache2 restart

and that´s it.

I have ubuntu server 17.10, orale client 12.1.0.2.0 oci8 ver. 2.1.3
I hope it works for u

I had the same problem on Ubuntu 16.04 and this is how i resolved it.

1. Make sure you add this line extension = oci8.so to /etc/php/7.1/apache2/php.ini to make apache aware of oci8
2. Add the following lines to /etc/apache2/envvars
   export LD_LIBRARY_PATH=/opt/oracle/instantclient_12_2
   export ORACLE_HOME=/opt/oracle/instantclient_12_2
3. Finally restart apache2 using the command /etc/init.d/apache2 restart

Thank you!

Hi,

Any help with the below error will be much appreciated:

PHP Warning: PHP Startup: Unable to load dynamic library 'oci8.so' (tried: /usr/lib/php/20170718/oci8.so (libmql1.so: cannot open shared object file: No such file or directory), /usr/lib/php/20170718/oci8.so.so (/usr/lib/php/20170718/oci8.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

@nwaweru Where are you seeing that message? In the terminal, when you execute php? Or when you attempt to start the webserver? Also, which OS are you using?

If you're seeing that error in the terminal, then you need to add the Instant Client path to the environment. On Ubuntu 18.04 LTS, for example:

echo 'LD_LIBRARY_PATH="/opt/oracle/instantclient_12_2"' >> /etc/environment

You should then log out of the terminal session and then back in, and the error should disappear.

If you're seeing this error when you start the apache2 daemon, then you need to add the LD_LIBRARY_PATH value to your Apache environment, e.g.:

echo 'export LD_LIBRARY_PATH=/opt/oracle/instantclient_12_2' >> /etc/apache2/envvars

And then restart the Apache service.

For whatever reason, none of this was needed on Ubuntu 16.04 LTS, but it appears to be required in Ubuntu 18.04 LTS.

Unfortunately, I can't figure out how to apply the same solution to PHP-FPM running via NGINX. I've tried adding

env['LD_LIBRARY_PATH'] = /opt/oracle/instantclient_12_2

to the effective FPM pool configuration, and while the Environment section of phpinfo()'s output reflects the above value, the OCI8 extension simply does not load. I don't see any errors in relation to libmql1.so in the FPM log, either, even with verbosity set to debug. Really frustrating!!!

Hello guys, for any has this problem
"PHP Warning: PHP Startup: Unable to load dynamic library 'oci8.so' (tried: /usr/lib/php/20170718/oci8.so (libmql1.so: cannot open shared object file: No such file or directory), /usr/lib/php/20170718/oci8.so.so (/usr/lib/php/20170718/oci8.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0"

I solved adding the following to /etc/environment:
LD_LIBRARY_PATH=/opt/oracle/instantclient_12_2:$LD_LIBRARY_PATH

I also had the same PHP Warning as above and I solved it by following this tutorial:

hi,
i am getting the error below. how to resolve it?
Warning: oci_connect(): ORA-12154: TNS:could not resolve the connect identifier specified in /app/src/public/oci8.php on line 3

Fatal error: ORA-12154: TNS:could not resolve the connect identifier specified in /app/src/public/oci8.php on line 7

I had:
php -m | grep 'oci8'

Then I use:
cat /etc/ld.so.conf.d/oracle-instantclient.conf
/opt/oracle/instantclient_18_3

sudo ldconfig -f /etc/ld.so.conf -C /etc/ld.so.cache

And that's all

solved with:

echo "/opt/oracle-instantclient-12-2" >> /etc/ld.so.conf.d/x86_64-linux-gnu.conf
ldconfig

and restart the php-fpm service

solved with:

echo "/opt/oracle-instantclient-12-2" >> /etc/ld.so.conf.d/x86_64-linux-gnu.conf
ldconfig

and restart the php-fpm service

Thank you

it should be

Please check have just one version php on your server I have had because I had two versions php

The instructions above helped me a lot. I was able to get a PHP 7 application running with this Dockerfile:

FROM php:7.2.10-apache

RUN docker-php-ext-install mysqli && docker-php-ext-enable mysqli
RUN apt-get update

COPY instantclient-basic-linux.x64-12.2.0.1.0 /opt/oracle/instantclient/
COPY instantclient-sdk-linux.x64-12.1.0.2.0 /opt/oracle/instantclient/

RUN ln -s /opt/oracle/instantclient/libclntsh.so.12.1 /opt/oracle/instantclient/libclntsh.so

RUN echo '/opt/oracle/instantclient' > /etc/ld.so.conf.d/oracle-instantclient.conf \
    && ldconfig

RUN apt-get install build-essential libaio1 -y
    
RUN echo 'instantclient,/opt/oracle/instantclient' | pecl install oci8-2.2.0 \
       && echo "extension=oci8.so" > /usr/local/etc/php/conf.d/php-oci8.ini

In my case, I also had to install mysql extension because of the application's requirements. So you can ignore the first RUN instruction.

# pecl install oci8
pecl/oci8 requires PHP (version >= 8.1.0), installed version is 7.0.33-0ubuntu0.16.04.16
No valid packages found
install failed

For the above failure use below command.

pecl install oci8-2.2.0

When i ran the procedure this was my error :
PHP Warning: PHP Startup: Unable to load dynamic library 'oci8_19' (tried: /usr/lib/php/20210902/oci8_19 (/usr/lib/php/20210902/oci8_19: cannot open shared object file: No such file or directory), /usr/lib/php/20210902/oci8_19.so (/usr/lib/php/20210902/oci8_19.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

I had: php -m | grep 'oci8' PHP Warning: PHP Startup: Unable to load dynamic library 'oci8.so' (tried: /usr/lib/php/20180731/oci8.so (libmql1.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

Then I use: cat /etc/ld.so.conf.d/oracle-instantclient.conf /opt/oracle/instantclient_18_3

sudo ldconfig -f /etc/ld.so.conf -C /etc/ld.so.cache

And that's all

Thank you
