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.x64-11.2.0.4.0.zip and instantclient-sdk-linux.x64-11.2.0.4.0.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.x64-11.2.0.4.0.zip
unzip instantclient-sdk-linux.x64-11.2.0.4.0.zip

Step 4

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

ln -s /opt/oracle/instantclient_11_2/libclntsh.so.11.1 /opt/oracle/instantclient_11_2/libclntsh.so
ln -s /opt/oracle/instantclient_11_2/libocci.so.11.1 /opt/oracle/instantclient_11_2/libocci.so

Step 5

Add the folder to our ldconfig.

echo /opt/oracle/instantclient_11_2 > /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_11_2

Step 3

We need to tell PHP to load the OCI8 extension.

echo "extension = oci8.so" >> /etc/php/7.2/apache2/php.ini

Step 4

Check if the extension is enabled.

php -m | grep 'oci8'

If returns oci8, its works!

Step 5

Add the following lines to /etc/apache2/envvars

export LD_LIBRARY_PATH=/opt/oracle/instantclient_11_2
export ORACLE_HOME=/opt/oracle/instantclient_11_2

Step 6

Restart the Apache

service apache2 restart

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